Look, science is hard, it has a reputation of being hard, and the facts are, it is hard, and that's the result of 400 years of science, right? I mean, in the 18th century, in the 18th century you could become an expert on any field of science in an afternoon by going to a library, if you could find the library, right?Seth Shostak Seth Shostak Sayings By Seth Shostak: Look, science is hard, it has a reputation of being hard, and the facts are,
While human space travel is daunting, machines - with their indefinitely long lifetimes - could travel the galaxy. It might make little difference to them that bridging the distance from one star to the next could take hundreds of thousands of years or more.Seth Shostak Seth Shostak Sayings By Seth Shostak: While human space travel is daunting, machines - with their indefinitely long lifetimes - could
Like prospecting in the 19th century, reconnaissance of the asteroids would of necessity take place in an arena where trouble is likely and help is distant. Heroic stories of individual triumph and failure, set on landscapes never seen by humankind, are in the cards.Seth Shostak Seth Shostak Sayings By Seth Shostak: Like prospecting in the 19th century, reconnaissance of the asteroids would of necessity take place
Studying Sol's interior by looking for analogous patterns on its incandescent face is known as helioseismology, an active - if largely unpronounceable - research area that uses sound as a probe of our home star.Seth Shostak Seth Shostak Sayings By Seth Shostak: Studying Sol's interior by looking for analogous patterns on its incandescent face is known as
It seems obvious that if a species has the brainpower for speech, along with the sort of appendages that can manipulate a pair of pliers, it will eventually blunder into science, technology, and radio.Seth Shostak Seth Shostak Sayings By Seth Shostak: It seems obvious that if a species has the brainpower for speech, along with the
The fact that we can't easily foresee clues that would betray an intelligence a million millennia farther down the road suggests that we're like ants trying to discover humans. Ask yourself: Would ants ever recognize houses, cars, or fire hydrants as the work of advanced biology?Seth Shostak Seth Shostak Sayings By Seth Shostak: The fact that we can't easily foresee clues that would betray an intelligence a million
The idea of close encounters of the zero'th kind - which is to say, not a close encounter at all, but simply uncovering evidence that someone's out there - dates back to the Victorian era.Seth Shostak Seth Shostak Sayings By Seth Shostak: The idea of close encounters of the zero'th kind - which is to say, not
While about one-third of Americans believe in ghosts, you won't find many exhibits on these spooky beings down at the local science museum. Why? Well, one explanation that you might consider, ghosts are just figments of our highly fertile imaginations!Seth Shostak Seth Shostak Sayings By Seth Shostak: While about one-third of Americans believe in ghosts, you won't find many exhibits on these
The central region of the Milky Way, known as the bulge, is stuffed with literally tens of billions of stars. And most of these are old - considerably older than our Sun or its neighbors - because this part of the galaxy formed first. Consequently, bulge stars are generally deficient in heavy elements.Seth Shostak Seth Shostak Sayings By Seth Shostak: The central region of the Milky Way, known as the bulge, is stuffed with literally
The usual metric for whether a planet is habitable or not is to ascertain whether liquid water could exist on its surface. Most worlds will either be too cold, too hot or of a type (like Jupiter) that may have no solid surface and be swaddled in noxious gases.Seth Shostak Seth Shostak Sayings By Seth Shostak: The usual metric for whether a planet is habitable or not is to ascertain whether
It's worth noting that invoking God as the entity who set our universe in motion isn't contradicted by the data. Of course, scientists would say the supreme being hypothesis is faith, and outside the realm of science - that it's not amenable to experiment. But we currently have the same problem with the notion of parallel universes.Seth Shostak Seth Shostak Sayings By Seth Shostak: It's worth noting that invoking God as the entity who set our universe in motion
Lamentably, alien audiences may be frustrated by the switch to digital television. That's because the transmitter power for DTV is fairly evenly spread across the spectrum. The spikiness is gone, and from afar, the attention-grabbing squeals of analog television's carriers have been replaced by DTV's smooth, low hiss.Seth Shostak Seth Shostak Sayings By Seth Shostak: Lamentably, alien audiences may be frustrated by the switch to digital television. That's because the
The next time you check your moves in the mirror and reflect on how special you are, consider that somewhere in this universe or in another parallel universe, your double might be doing the same. This would be the ultimate Copernican Revolution. Not only are we not special, we could be infinitely ordinary.Seth Shostak Seth Shostak Sayings By Seth Shostak: The next time you check your moves in the mirror and reflect on how special
Very few societies on Earth developed science as we know it today. On the other hand, the number is not zero - the Greeks, the Chinese, and the Maya did, among others. Once invented, science proved so useful that it spread like mold on a petri dish.Seth Shostak Seth Shostak Sayings By Seth Shostak: Very few societies on Earth developed science as we know it today. On the other
We're not just any star stuff, most of which is humdrum hydrogen and listless helium. Our bodies include fancier ingredients like carbon, oxygen, nitrogen, phosphorous, and a few other herbs and spices.Seth Shostak Seth Shostak Sayings By Seth Shostak: We're not just any star stuff, most of which is humdrum hydrogen and listless helium.
The stars look the same from night to night. Nebulae and galaxies are dully immutable, maintaining the same overall appearance for thousands or millions of years. Indeed, only the sun, moon and planets - together with the occasional comet, asteroid or meteor - seem dynamic.Seth Shostak Seth Shostak Sayings By Seth Shostak: The stars look the same from night to night. Nebulae and galaxies are dully immutable,
I still remember my dismay in the summer of 2007 when - for the first time in the history of planet Earth - America's share of auto production dropped below 50 percent.Seth Shostak Seth Shostak Sayings By Seth Shostak: I still remember my dismay in the summer of 2007 when - for the first
We're interested in things that have big teeth, and you can see the evolutionary value of that, and you can also see the practical consequences by watching 'Animal Planet.' You notice they make very few programs about gerbils. It's mostly about things that have big teeth.Seth Shostak Seth Shostak Sayings By Seth Shostak: We're interested in things that have big teeth, and you can see the evolutionary value
'Battleship' is not a film that Francois Truffaut would have made. Nor would any of those other namby-pamby European directors. Nope, this picture eschews that Continental obsession with small stories, set in quaint towns filled with pockmarked folk doing their banal things.Seth Shostak Seth Shostak Sayings By Seth Shostak: 'Battleship' is not a film that Francois Truffaut would have made. Nor would any of
The thing to keep in mind is that we're still in the very early days when it comes to the search for extraterrestrial intelligence. Saying there's a silence is a bit like if Columbus, looking to discover a new continent, only sailed 10 miles off the coast of Spain before turning back to say, 'Nothing out there!'Seth Shostak Seth Shostak Sayings By Seth Shostak: The thing to keep in mind is that we're still in the very early days
Despite the impression you may have from watching too much TV, movies are not about reproducing reality. They're about telling stories.Seth Shostak Seth Shostak Sayings By Seth Shostak: Despite the impression you may have from watching too much TV, movies are not about
Our retinas and brains have been wired by a hundred million years of evolution to find outlines in a visually complex landscape. This helps us to recognize prey and predators.Seth Shostak Seth Shostak Sayings By Seth Shostak: Our retinas and brains have been wired by a hundred million years of evolution to
Sending greeting cards to aliens is hardly a new idea. In 2005, Craigslist solicited messages for broadcast to space by a transmitter in Florida, and in 2008, NASA beamed a Beatles song to the North Star (Polaris), on the assumption that any putative Polarians would appreciate the Fab Four's 1960s-genre compositions.Seth Shostak Seth Shostak Sayings By Seth Shostak: Sending greeting cards to aliens is hardly a new idea. In 2005, Craigslist solicited messages
There will be an end point to how good TV pictures can get. The boob tube has hugely benefited from the rapid advance of digital electronics. Consequently, the strategy for hardware has changed. In the old days, sets had to be as simple as Elmer Fudd to keep them inexpensive. All the technical 'smarts' were at the transmitter end.Seth Shostak Seth Shostak Sayings By Seth Shostak: There will be an end point to how good TV pictures can get. The boob
It's hard to imagine anything more interesting than learning how we're woven into the enormous tapestry of existence. Where did our universe come from? How special is our world, and how special are we? We allocate tens of billions of dollars annually to NASA, NSF and academia in search of the answers.Seth Shostak Seth Shostak Sayings By Seth Shostak: It's hard to imagine anything more interesting than learning how we're woven into the enormous
When I graduated high school, nearly a half-million people subscribed to 'Popular Electronics' magazine. Soldering up some radio or hi-fi amplifier on the basement workbench was not just a personal passion - a lot of young people were doing the same. The magazine expired in 1999 for lack of interest.Seth Shostak Seth Shostak Sayings By Seth Shostak: When I graduated high school, nearly a half-million people subscribed to 'Popular Electronics' magazine. Soldering
Everything you see is filtered through your visual system (imperfect) and your brain (also imperfect, despite what your mom told you). Witness testimony is the worst kind of evidence in science.Seth Shostak Seth Shostak Sayings By Seth Shostak: Everything you see is filtered through your visual system (imperfect) and your brain (also imperfect,
Exploration is an oft-lauded human activity, and one that resonates in the same way that music and good stories do. It's hard-wired into our species (and into many others), no doubt because it has survival value. Exploration occasionally rewards those who accept its risks, usually with new resources.Seth Shostak Seth Shostak Sayings By Seth Shostak: Exploration is an oft-lauded human activity, and one that resonates in the same way that
Ever since the infamous quiz show scandals of the 1950s, the feds had insisted that TV game shows be honest - or that at least they didn't cheat. So as a 'Dating Game' bachelor, I didn't know what I was going to be asked. The other bachelors and I were required to concoct our answers in real time.Seth Shostak Seth Shostak Sayings By Seth Shostak: Ever since the infamous quiz show scandals of the 1950s, the feds had insisted that
Mountains aren't eternal: even the most imposing massifs are smoothed away by weathering in a few hundred million years or less. Plate tectonics makes new ones, and without it, our future would be flat.Seth Shostak Seth Shostak Sayings By Seth Shostak: Mountains aren't eternal: even the most imposing massifs are smoothed away by weathering in a
Even if the Moon didn't exist - even if it had been vaporized billions of years ago by cantankerous Klingons - there would still be (somewhat lower) tides raised by the Sun. For creatures dependent on the oceans' ebb and flow, life could go on.Seth Shostak Seth Shostak Sayings By Seth Shostak: Even if the Moon didn't exist - even if it had been vaporized billions of
Admittedly, it would take industrial-grade chutzpah and a massive dose of malevolence for anyone to bulldoze the spot where Neil Armstrong stepped off the Eagle lander. But even innocent visits could be damaging.Seth Shostak Seth Shostak Sayings By Seth Shostak: Admittedly, it would take industrial-grade chutzpah and a massive dose of malevolence for anyone to
If the cosmos isn't finite, then far, far away, floating duplicates of your brain - with all its experiences, thoughts, and emotions - are occasionally (and temporarily) thrown together by the random combining of atoms. Such 'Boltzmann brains,' as they're called, are a disturbing consequence of an unlimited universe.Seth Shostak Seth Shostak Sayings By Seth Shostak: If the cosmos isn't finite, then far, far away, floating duplicates of your brain -
We haven't yet found a speck of evidence for biology on another world, so we have no objective way to judge whether life is a onetime fluke or a near-inevitable phenomenon.Seth Shostak Seth Shostak Sayings By Seth Shostak: We haven't yet found a speck of evidence for biology on another world, so we
I think a lot of kids are interested in two science subjects: dinosaurs and aliens. The reason is almost genetic; we're hard-wired to be interested in things that might be a little dangerous.Seth Shostak Seth Shostak Sayings By Seth Shostak: I think a lot of kids are interested in two science subjects: dinosaurs and aliens.
There is a point of view among astronomical researchers that is generally referred to as the Principle of Mediocrity ... If the Sun and its retinue of worlds is only one system among many, then many other systems will be like ours: home to life. Indeed, to the extent that this is true, we should be prepared for the possibility that, even in the Milky Way galaxy, billions of planets may be carpeted by the dirty, nasty business known as life.Seth Shostak Seth Shostak Sayings By Seth Shostak: There is a point of view among astronomical researchers that is generally referred to as
It bears mentioning that the Milky Way is only one of 150 billion galaxies visible to our telescopes - and each of these will have its own complement of planets.Seth Shostak Seth Shostak Sayings By Seth Shostak: It bears mentioning that the Milky Way is only one of 150 billion galaxies visible
It's hardly a secret that I'm skeptical of declarations that the aliens are out and about on our planet. Still, I try to answer every one of these mails and phone calls because, after all, it's not a violation of physics to travel from one star system to another.Seth Shostak Seth Shostak Sayings By Seth Shostak: It's hardly a secret that I'm skeptical of declarations that the aliens are out and
The most attractive habitats for synthetic sentience might be the vicinities of exceptional sources of energy - for example black holes, or even the neighbourhoods of large stars, which routinely boil off the energy of ten thousand suns. These are the destinations they may seek.Seth Shostak Seth Shostak Sayings By Seth Shostak: The most attractive habitats for synthetic sentience might be the vicinities of exceptional sources of
When I was a kid, which was just after Edison invented moving pictures, there were films that involved aliens coming to Earth for bad purposes.Seth Shostak Seth Shostak Sayings By Seth Shostak: When I was a kid, which was just after Edison invented moving pictures, there were
If you could drive straight down, into a tunnel bored through the crust of the planet, you'd hit this molten mess in about an hour. It's called the asthenosphere - a sluggish sea, several hundred miles thick, on which floats the Earth's cool epidermis - the so-called tectonic plates.Seth Shostak Seth Shostak Sayings By Seth Shostak: If you could drive straight down, into a tunnel bored through the crust of the
The planets and moons of our solar system are blatantly visible because they reflect sunlight. Without the nearby Sun, these planets would be cryptic and dark on the sky.Seth Shostak Seth Shostak Sayings By Seth Shostak: The planets and moons of our solar system are blatantly visible because they reflect sunlight.
The total funding of SETI (the Search for Extraterrestrial Intelligence) in the U.S. is 0.0003 percent of the tax monies spent on health and human services. And it's not even tax money. The SETI Institute's hunt for signals is funded by donations.Seth Shostak Seth Shostak Sayings By Seth Shostak: The total funding of SETI (the Search for Extraterrestrial Intelligence) in the U.S. is 0.0003
Clearly, enriching the cosmos with heavy elements takes a while. So there's inevitably an interval between the sterile aftermath of the Big Bang and a time when the cosmic chemistry set had enough ingredients to make rocky planets (and squishy biology).Seth Shostak Seth Shostak Sayings By Seth Shostak: Clearly, enriching the cosmos with heavy elements takes a while. So there's inevitably an interval
Astronomers still can't decide what the shape of our universe is. Is it closed and finite, which is to say, is there a countable tally of all the galaxies that exist, even beyond the ones we can see? Or is it infinite? The latter possibility is still on the table.Seth Shostak Seth Shostak Sayings By Seth Shostak: Astronomers still can't decide what the shape of our universe is. Is it closed and
Heads are a good deal, and I think they would be a common feature. It's hard to think of species that don't have heads, although there are some. It's good to have a head because it puts some of the sensory organs - eyes, ears, whiskers or whatever - next to the CPU, the brain.Seth Shostak Seth Shostak Sayings By Seth Shostak: Heads are a good deal, and I think they would be a common feature. It's
Every day, the temperature of Sol's surface increases by five billionths of a degree, a change of no consequence for thousands of millennia to come. But a few hundred million years from now, barring a fix by our descendants, this relentless heating will substantially change Earth's biosphere in ways that might not be survivable for us.Seth Shostak Seth Shostak Sayings By Seth Shostak: Every day, the temperature of Sol's surface increases by five billionths of a degree, a
If you took all the sand from all the beaches, all the desserts, and all the oceans and called that the Universe, our whole solar system would be less than one grain of sand.Seth Shostak Seth Shostak Sayings By Seth Shostak: If you took all the sand from all the beaches, all the desserts, and all
Are two eyes, four appendages and an upright posture really essential for any creature that can ace the galactic SAT's? Maybe not. In fact, I'd venture that any aliens we ever detect or (less likely) encounter will look quite different than this self-referential stereotype.Seth Shostak Seth Shostak Sayings By Seth Shostak: Are two eyes, four appendages and an upright posture really essential for any creature that
Here's a news flash: scientists can be wrong. That's no big deal (unless the scientist is you), since research is self-correcting. Consequently, most errors by scientists become historical curiosities, with little long-term importance.Seth Shostak Seth Shostak Sayings By Seth Shostak: Here's a news flash: scientists can be wrong. That's no big deal (unless the scientist
About the only things that are unique to Earth are our biota and our culture. If aliens ever come here, they'd most likely be either biologists or music fans. Neither one has much reason to antagonize our armed forces.Seth Shostak Seth Shostak Sayings By Seth Shostak: About the only things that are unique to Earth are our biota and our culture.
The number of habitable worlds in our galaxy is certainly in the tens of billions, minimum, and we haven't even talked about the moons. And the number of galaxies we can see, other than our own, is about 100 billion.Seth Shostak Seth Shostak Sayings By Seth Shostak: The number of habitable worlds in our galaxy is certainly in the tens of billions,
We'll be 'outsourcing' our creativity and our thought processes to manufactured components that could be inconspicuously implanted beneath our coiffeurs. Welcome to the Borg. You might not be entirely comfortable with such cybernetic enhancements, but all the smart money says it's going to happen.Seth Shostak Seth Shostak Sayings By Seth Shostak: We'll be 'outsourcing' our creativity and our thought processes to manufactured components that could be
What's a space elevator? Simply described, it's a thin ribbon, about 3 feet wide and 60 thousand miles long, stretching upwards from the surface of the Earth. The lower end is bolted to a heavy anchor (think of an oil drilling platform), and the top is capped with a counterweight.Seth Shostak Seth Shostak Sayings By Seth Shostak: What's a space elevator? Simply described, it's a thin ribbon, about 3 feet wide and
Typically, only about 2 percent of the American populace tunes in to PBS's 'Nova' series - the most successful science show on the tube. 'Survivor' and 'X Factor' get twice the ratings.Seth Shostak Seth Shostak Sayings By Seth Shostak: Typically, only about 2 percent of the American populace tunes in to PBS's 'Nova' series
We come from goldfish, essentially, but that [doesn't] mean we turned around and killed all the goldfish. Maybe [the AIs] will feed us once a week ... . If you had a machine with a 10 to the 18th power IQ over humans, wouldn't you want it to govern, or at least control your economy? - SETH SHOSTAKRay Kurzweil Seth Shostak Sayings By Ray Kurzweil: We come from goldfish, essentially, but that [doesn't] mean we turned around and killed all
In 1908, there was a persuasive demonstration of the power of high-speed, low-mass asteroids in rural Siberia. The Tunguska impactor iced millions of pine trees and about a zillion mosquitoes - and was no larger than an office building.Seth Shostak Seth Shostak Sayings By Seth Shostak: In 1908, there was a persuasive demonstration of the power of high-speed, low-mass asteroids in
The bottom line is that the position of the Sun relative to the stars slowly changes for any given date, and over the course of 26,000 years, it can easily slide between constellations. So you may think you're a Pisces, but you're actually an Aquarius.Seth Shostak Seth Shostak Sayings By Seth Shostak: The bottom line is that the position of the Sun relative to the stars slowly
The overwhelming bulk of the cosmos is deathly quiet. But here and there - on worlds where matter is thick and conditions are right - noises are commonplace. And in some cases, these noisy worlds may ring with the sounds of life - the bleats and bellows of creatures we have never seen, but may someday discover.Seth Shostak Seth Shostak Sayings By Seth Shostak: The overwhelming bulk of the cosmos is deathly quiet. But here and there - on
Star Trek's genial premise is that the cosmos is flush with intelligent species, and our descendants will interact with them face-to-face, thanks to warp drive and some winsome space cadets.Seth Shostak Seth Shostak Sayings By Seth Shostak: Star Trek's genial premise is that the cosmos is flush with intelligent species, and our
Sure, nobody will make a fortune if we figure out why the Big Bang happened. But just about everyone would like to know.Seth Shostak Seth Shostak Sayings By Seth Shostak: Sure, nobody will make a fortune if we figure out why the Big Bang happened.
Scientists - who prefer explanations subject to laboratory tests - figure that everything we see today was as inevitable as wrinkles, once the Big Bang established physics. Stars and planets were cooked up as huge clouds of matter collapsed and coalesced.Seth Shostak Seth Shostak Sayings By Seth Shostak: Scientists - who prefer explanations subject to laboratory tests - figure that everything we see
The strongest signals leaking off our planet are radar transmissions, not television or radio. The most powerful radars, such as the one mounted on the Arecibo telescope (used to study the ionosphere and map asteroids) could be detected with a similarly sized antenna at a distance of nearly 1,000 light-years.Seth Shostak Seth Shostak Sayings By Seth Shostak: The strongest signals leaking off our planet are radar transmissions, not television or radio. The
Recent results from astronomers who study the occasional gravitational lensing of unknown worlds by intervening stars suggest that orphan planets could be at least as numerous as the stars. In other words, there could be hundreds of billions of orphan worlds shuffling through our galaxy.Seth Shostak Seth Shostak Sayings By Seth Shostak: Recent results from astronomers who study the occasional gravitational lensing of unknown worlds by intervening
The total number of people that do a job that has the same description as mine in the entire world is fewer than 10. There's a lot of effort looking for life in space - that's a lot of what NASA does, but they're not necessarily looking for the kind of life that can hold up its side of a conversation.Seth Shostak Seth Shostak Sayings By Seth Shostak: The total number of people that do a job that has the same description as
The Moon is a ball of left-over debris from a cosmic collision that took place more than four billion years ago. A Mars-sized asteroid - one of the countless planetesimals that were frantically churning our solar system into existence - hit the infant Earth, bequeathing it a very large natural satellite.Seth Shostak Seth Shostak Sayings By Seth Shostak: The Moon is a ball of left-over debris from a cosmic collision that took place
By 2020, most home computers will have the computing power of a human brain. That doesn't mean that they are brains, but it means that in terms of raw processing, they can process bits as fast as a brain can. So the question is, how far behind that is the development of a machine that's as smart as we are?Seth Shostak Seth Shostak Sayings By Seth Shostak: By 2020, most home computers will have the computing power of a human brain. That
Charles Darwin sailed around the world for two years on the 'Beagle,' and he had quite a bit of interest in things like the iguanas of the Galapagos, even though they were primitive compared to your average Englishman.Seth Shostak Seth Shostak Sayings By Seth Shostak: Charles Darwin sailed around the world for two years on the 'Beagle,' and he had
The Earth has been lawned with life for something over 3.5 billion years. That's a span of time great enough to encompass some honest-to-goodness catastrophe. For example, 700 million years ago, Earth underwent a planet-wide deep freeze, with ice covering the oceans from the poles to the equator.Seth Shostak Seth Shostak Sayings By Seth Shostak: The Earth has been lawned with life for something over 3.5 billion years. That's a
The ideas of science germinate in a matrix of established knowledge gained by experiment; they are not lonesome thoughts, born in a rarified realm where no researcher has ever gone before.Seth Shostak Seth Shostak Sayings By Seth Shostak: The ideas of science germinate in a matrix of established knowledge gained by experiment; they
One of the jovian moons, Europa, is coated with twice as much liquid water as is sloshing around our planet.Seth Shostak Seth Shostak Sayings By Seth Shostak: One of the jovian moons, Europa, is coated with twice as much liquid water as
'What was there before the Big Bang?' That's a question that both kids and adults love to pose to anyone who seems sympathetic. After all, if the universe has only been around for roughly 14 billion years, isn't it legitimate to ask what was in existence before the mother-of-all-events cranked up the cosmos?Seth Shostak Seth Shostak Sayings By Seth Shostak: 'What was there before the Big Bang?' That's a question that both kids and adults
It seems that 'rocket scientist' is a job category that's here for the long haul, like 'mortician.' But all this activity masks an important point: rockets are not a terribly efficient way to lift things into space.Seth Shostak Seth Shostak Sayings By Seth Shostak: It seems that 'rocket scientist' is a job category that's here for the long haul,
In a movie, it's often important to have aliens whose gestures and facial expressions can be 'read' by humans. And in the days before sophisticated computer animation, most extraterrestrial bit players were guys in rubber suits. Such practical considerations forced Hollywood's hand when it came to aliens - they look like us for good reasons.Seth Shostak Seth Shostak Sayings By Seth Shostak: In a movie, it's often important to have aliens whose gestures and facial expressions can
I studied Latin in high school, and I was reading stuff from Cicero. And that signal took a few thousand years to get to me. But I was still interested in what he had to say.Seth Shostak Seth Shostak Sayings By Seth Shostak: I studied Latin in high school, and I was reading stuff from Cicero. And that
Of course there is still unexplored terrestrial territory, but most of it is waterlogged. Submersed secret places, such as the Challenger Deep, which today lure hi-tech adventurers like Richard Branson and James Cameron, will undoubtedly provide welcome fodder for 'National Geographic.'Seth Shostak Seth Shostak Sayings By Seth Shostak: Of course there is still unexplored terrestrial territory, but most of it is waterlogged. Submersed
Humans have existed only for the last 0.001 percent of cosmic time. All of which says that - unless the Homo sapiens brain is the one-and-only instance of cogitating machinery - nearly all the intelligence that's out there is beyond our level. And that intelligence is more than just a little bit beyond.Seth Shostak Seth Shostak Sayings By Seth Shostak: Humans have existed only for the last 0.001 percent of cosmic time. All of which
In general, when moviemakers talk to scientists, they usually see them as a resource to solve particular technical problems or script problems for them. So, something like: what sort of weaponry would aliens be able to wield?Seth Shostak Seth Shostak Sayings By Seth Shostak: In general, when moviemakers talk to scientists, they usually see them as a resource to
We can no better imagine what will be happening on the moon 500 years from now than Columbus could imagine contemporary Manhattan. Except to say that it will be a place familiar to billions of people.Seth Shostak Seth Shostak Sayings By Seth Shostak: We can no better imagine what will be happening on the moon 500 years from
The search for extra-terrestrial life is a failure until that moment when it suddenly becomes a success.Seth Shostak Seth Shostak Sayings By Seth Shostak: The search for extra-terrestrial life is a failure until that moment when it suddenly becomes
The limitless content of our universe might be only one instance of a large (and possibly infinite) number of other universes.Seth Shostak Seth Shostak Sayings By Seth Shostak: The limitless content of our universe might be only one instance of a large (and
Mars still remains the astrobiology community's number one choice for 'nearest rock with life,' but there are many researchers who argue that the moons of Jupiter are better bets. In particular, Europa, Ganymede, and Callisto are all thought to hide vast oceans of liquid water beneath their icy, outer skins.Seth Shostak Seth Shostak Sayings By Seth Shostak: Mars still remains the astrobiology community's number one choice for 'nearest rock with life,' but
Any beings advanced enough to traverse interstellar distances are at least a thousand years beyond our technical level. Spending gobs of time examining our missiles is equivalent to sending the Air Force back to the Middle Ages and insisting they examine the chain mail factories.Seth Shostak Seth Shostak Sayings By Seth Shostak: Any beings advanced enough to traverse interstellar distances are at least a thousand years beyond
I've often fantasized about visiting the Bahamian beach where Columbus first stumbled ashore in 1492. Sadly, no one knows where that beach is. In fact, no one's even sure which island Columbus first encountered (there are three candidates). It's a pity, a disappointment, and a lost revenue source for the Bahamians.Seth Shostak Seth Shostak Sayings By Seth Shostak: I've often fantasized about visiting the Bahamian beach where Columbus first stumbled ashore in 1492.
On Mars, where the air is spare - a hundred times less dense than on Earth - someone could hear you scream. But you'd have to really strain to get anyone's attention. On the Red Planet, where the wind is high-pitched and faint, even a symphony orchestra will sound as thin as cheap gruel.Seth Shostak Seth Shostak Sayings By Seth Shostak: On Mars, where the air is spare - a hundred times less dense than on
In archaeology, context is the basis of many discoveries that are imputed to the deliberate workings of intelligence. If I find a rock chipped in such a way as to give it a sharp edge, and the discovery is made in a cave, I am seduced into ascribing this to tool use by distant, fetid and furry ancestors.Seth Shostak Seth Shostak Sayings By Seth Shostak: In archaeology, context is the basis of many discoveries that are imputed to the deliberate
'E.T.' was far-fetched. 'E.T.' was this wimpy-looking kid that came to Earth to pick some plants, but he came from the Andromeda Galaxy to do that.Seth Shostak Seth Shostak Sayings By Seth Shostak: 'E.T.' was far-fetched. 'E.T.' was this wimpy-looking kid that came to Earth to pick some
The bottom line is, like, one in five stars has at least one planet where life might spring up. That's a fantastically large percentage. That means in our galaxy, there's on the order of tens of billions of Earth-like worlds.Seth Shostak Seth Shostak Sayings By Seth Shostak: The bottom line is, like, one in five stars has at least one planet where
When was the last time you bought an American-made radio or television? If you're Gen X or younger, the answer is 'never.' Does the label on that shirt or skirt you're wearing say 'Made in the U.S.A.'? If so, you probably got it at Goodwill, or maybe at a Smithsonian garage sale.Seth Shostak Seth Shostak Sayings By Seth Shostak: When was the last time you bought an American-made radio or television?

Virtually any pointed edifice is considered a candidate for alien engineering.

Engineers are now experimenting with 4,096-line TV systems, suggesting that with the next generation of sets you'll be able to count the grass blades on the Superbowl field, an obvious lifestyle improvement.Seth Shostak Seth Shostak Sayings By Seth Shostak: Engineers are now experimenting with 4,096-line TV systems, suggesting that with the next generation of
We're hard-wired by 200,000 years of evolution to be sensitive to the idea that someone might be watching us. They might be predators, after all. An uneasy feeling is perfectly natural if you suspect that someone has you in their ocular sights, whether it's a ghost or just some guy at the bus stop.Seth Shostak Seth Shostak Sayings By Seth Shostak: We're hard-wired by 200,000 years of evolution to be sensitive to the idea that someone
The longtime standard for American TV was 525 lines from top to bottom of the image. As a practical matter, that was roughly equivalent to 350 thousand pixels - pretty crude, given that photos made with your iPhone boast five million pixels.Seth Shostak Seth Shostak Sayings By Seth Shostak: The longtime standard for American TV was 525 lines from top to bottom of the
Consider that the overwhelming majority of those 40,000 near-Earth asteroids are small enough to fit on the parking lot at the mall. And while these rocky runts won't cause Armageddon, they could still flatten such popular hominid hangouts as Manhattan or downtown Des Moines.Seth Shostak Seth Shostak Sayings By Seth Shostak: Consider that the overwhelming majority of those 40,000 near-Earth asteroids are small enough to fit
Our brains are wired to interpret shapes as faces and bodies. That's why people see the Virgin Mary in the clouds or even in cheese sandwiches. It's your cytoplasm, not some strange ectoplasm.Seth Shostak Seth Shostak Sayings By Seth Shostak: Our brains are wired to interpret shapes as faces and bodies. That's why people see
[O]ne might ask why, in a galaxy of a few hundred billion stars, the aliens are so intent on coming to Earth at all. It would be as if every vertebrate in North America somehow felt drawn to a particular house in Peoria, Illinois. Are we really that interesting?Seth Shostak Seth Shostak Sayings By Seth Shostak: [O]ne might ask why, in a galaxy of a few hundred billion stars, the aliens
The bottom line is that finding orphan planets - small, faint, and located who-knows-where - is not for the faint of heart. The task is comparable to observing a match flame at the distance of Pluto. The WISE satellite, a hi-tech, space-based infrared telescope especially suited for such work, has found only a few.Seth Shostak Seth Shostak Sayings By Seth Shostak: The bottom line is that finding orphan planets - small, faint, and located who-knows-where -
Plate tectonics is not all havoc and destruction. The slow movement of continents and ocean floors recycles carbon dioxide dissolved in the oceans back into the atmosphere. Without this slow speed carbon cycle, Earth's temperatures would cool dozens of degrees below your comfort zone.Seth Shostak Seth Shostak Sayings By Seth Shostak: Plate tectonics is not all havoc and destruction.

Most of the intelligence out there must be artificial intelligence. We keep looking for critters like us living on a planet like ours, where in fact the majority of the intelligence out there is not biological. That would be my argument.Seth Shostak Seth Shostak Sayings By Seth Shostak: Most of the intelligence out there must be artificial intelligence. We keep looking for critters
The mission of NASA's Kepler telescope is to lift the scales from our eyes and reveal to us just how typical our home world is. Kepler operates by measuring the dimming of stars as planets pass ('transit') in front of them. It has found thousands of previously unknown worlds.Seth Shostak Seth Shostak Sayings By Seth Shostak: The mission of NASA's Kepler telescope is to lift the scales from our eyes and
