Neil deGrasse Tyson Quotes

It is surely unreasonable to credit that only one small star in the immensity of the universe is capable of developing and supporting intelligent life. But we shall not get to them and they will not come to us.

Perhaps, as some wit remarked, the best proof that there is Intelligent Life in Outer Space is the fact it hasn't come here. Well, it can't hide forever - one day we will overhear it.

I'm sure the universe is full of intelligent life. It's just been too intelligent to come here.

It's hard enougth to find intelligent life right here in Washington!

and we’ll be saying a big hello to all intelligent life forms everywhere … and to everyone else out there, the secret is to bang the rocks together, guys.

Another random thing I do is the search for extraterrestrial intelligence, or SETI. And you may be familiar with the movie 'Contact,' which sort of popularized that. It turns out there are real people who go out and search for extraterrestrials in a very scientific way.

Within the scientific community, there is healthy skepticism. And the question is, 'How do you ever get to a meaningful null result? How long and how hard do SETI scientists have to look for extraterrestrial intelligence and find nothing before they say, 'There is nothing. We are alone.'

While NASA talks about 'Are we alone?' as a number one question, they are putting zero money into searching for intelligent life. There's a big disconnect there.

We have never denied that it is possible, indeed probable, that other forms of life, even intelligent life, exist in the universe. But this is different from the belief that we are now being visited by extraterrestrial beings in spacecraft, that they are abducting people, and the there is a vast government cover-up.

I'd sooner exchange ideas with the birds on earth than learn to carry on intergalactic communications with some obscure race of humanoids on a satellite planet from the world of Betelgeuse.

I've been saying for a long time that I'm hoping to find intelligent life in Washington.

The best proof that there's intelligent life in the universe is that it hasn't come here.

Is mankind alone in the universe? Or are there somewhere other intelligent beings looking up into their night sky from very different worlds and asking the same kind of question?

NASA even sent Chuck Berry's music on a space probe searching for intelligent life in outer space. Well, now, if they're out there, they're duck walking

We may be living at that moment, on the cusp, when we go from being a species that feels a kind of loneliness in the cosmos to actually one sometime in the not too distant future being able to confirm the existence of other intelligent life.

Perhaps we've never been visited by aliens because they have looked upon Earth and decided there's no sign of intelligent life.

It's feasible that we'll meet other sentient life forms and conduct commerce with them. We don't now have the technology to physically travel outside our solar system for such an exchange to take place, but we are like Columbus centuries ago, learning fast how to get somewhere few think possible.

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.

We can never prove that we're alone in the universe. But the Allen Telescope Array could prove that we're not.

People quite often think of the question 'Are we alone in the universe?' in terms of other civilizations out there: life forms that have reached at least our level of technological development.

I think there's all kinds of life out there, including intelligent life, but the reason we haven't found each other is because of vast distances.

Galactic plankton is undoubtedly out there, but it's statistically highly likely there's also another intelligent civilisation out there somewhere. Unfortunately, the distances and time differences are so great, communication might remain impossible.

Radio astronomers are aware in the back of their minds that if there are other civilizations out there in space, it might be the radio astronomers who first pick up the signal.

The pulsar map is not dangerous at all. It will likely never even be seen by extraterrestrials.

I think it's fantastically narcissistic to believe that in the entire universe, with all of the planetary systems that we've already discovered and the countless others that are out there, that we are the only forms of life. Now, the real question is not are there other forms of life out there, but are there other intelligent forms of life out there right now. Because the universe is not only really big but it's also really long. It's been around for a long time; it's going to be around for a long time.
