Extraterrestrial Intelligence Quotes

Sometimes I think we're alone in the universe, and sometimes I think we're not. In either case the idea is quite staggering.

If you're sending a message to extraterrestrials, what you want to send is what's special about us and our planet - what is unusual. Now, that's not basic chemistry or mineralogy; it's pretty much the cultural stuff and the consequences of evolution.

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.

For many centuries, humans have speculated that there might be planetary systems around other stars and that there could be extraterrestrial life there and even intelligent being. However, those were simply speculations, and now we have evidence for the first part of these ideas.

If we ever established contact with intelligent life on another world, there would be barriers to communication. First, they would be many light years away, so signals would take many years to reach them: there would be no scope for quick repartee. There might be an IQ gap.

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!'

Listen, I mean that from my knowledge of the world that I see around me, I think that it is much more likely that the reports of flying saucers are the results of the known irrational characteristics of terrestrial intelligence than of the unknown rational efforts of extra-terrestrial intelligence.

What a splendid perspective contact with a profoundly different civilization might provide! In a cosmic setting vast and old beyond ordinary human understanding we are a little lonely, and we ponder the ultimate significance, if any, of our tiny but exquisite blue planet, the Earth.... In the deepest sense the search for extraterrestrial intelligence is a search for ourselves.

Extraterrestrial intelligence could have sent DNA-seed packets out through space to plant life on hospitable planets such as earth.

Ridley Scott's 'Prometheus' is a magnificent science-fiction film, all the more intriguing because it raises questions about the origin of human life and doesn't have the answers.

I think everyone agrees First Contact was our best film, and even at that, they're kind of... I don't know, they're sort of movies. But they're kind of really Star Trek movies, if you take my meaning. It's hard for me to say. I was glad to be doing them. Whether they were good isn't really up to me to determine, and it doesn't matter what I think. I thought we had a really nice script on Nemesis, and the audience didn't seem to care for it, so what can you do?

I think there's a lot of intelligence out there, but that's just my guess. Question is: Are they peaceable or hostile? You could say that the peaceable ones are just going to stay at home and play with their Nintendos, so if you do meet any of them, they might be hostile.

When I was a kid, I was obsessed with UFOs in particular, and the paranormal.

Like many of the ideas that mattered in the American Revolution, extraterrestrials got their start in antiquity. The Greek philosopher Epicurus speculated that the universe must be infinite, eternal and abounding in 'worlds' just like our own.

Maybe the search for life shouldn't restrict attention to planets like Earth. Science fiction writers have other ideas: balloon-like creatures floating in the dense atmospheres of planets such as Jupiter, swarms of intelligent insects, nano-scale robots and more.

We could tell them [alien civilization] things that we have discovered in the realm of mathematical physics, but there is stuff that I would like to know. There are some famous problems like how to bring gravitation and quantum physics together, the long-sought-after theory of quantum gravity. But it may be hard to understand the answer that comes back.

We know that within the solar system is very unlikely there will be anything more advanced than microbial life, but if we think outside the solar system and then, the distances are, of course, immense, then there could be Earth-like planets with more advanced form of life.

No one would have believed in the last years of the nineteenth century that this world was being watched keenly and closely by intelligences greater than man's and yet as mortal as his own; that as men busied themselves about their various concerns they were scrutinised and studied, perhaps almost as narrowly as a man with a microscope might scrutinise the transient creatures that swarm and multiply in a drop of water.

If we find life out there, and it's not us, we will deem it not intelligent. But what may be equally as likely is that we find life that's vastly more intelligent than we are. If that's the case, we are putty in their hands.

My only hope is that every other alien civilization isn't doing exactly what we are doing because then everybody would be listening, nobody would be receiving, and we would collectively conclude that there is no other intelligent life in the universe.

We only have to look at ourselves to see how intelligent life might develop into something we wouldnt want to meet. I imagine they might exist in massive ships, having used up all the resources from their home planet. Such advanced aliens would perhaps become nomads, looking to conquer and colonize whatever planets they can reach.

Why should we consider defining intelligence as something global and as something that hasn't actually yet appeared on Earth? It may be useful for envisioning the future of our own civilization and any others that may be out there among the stars. It might give us something to strive for.

We all have a right to know, and if the government has been suppressing information about other life forms, that's the cruelest hoax of all.

I hope that someday we will find evidence that there is intelligent life among humans on this planet.

I think humans are stupid. We fight and kill each other. I think that's dumb. Aliens would be smarter than that and wouldn't approach things on that level. I can't really fathom it being a negative thing for aliens to visit.
