This past weekend, Neil deGrasse Tyson did a reddit AMA: “I am Neil deGrasse Tyson, your personal Astrophysicist.”

Naturally, with this irresistible prompt, he got numerous responses, like this one: “Do you think we will ever make contact with complex organisms within the next 50 years?”

Unfortunately, for those hoping to make contact, this was his answer:

Fermi’s Paradox

There are around 100 billion planets in the Milky Way galaxy alone.

If even a tiny percentage of them are habitable (and they should be, even using conservative standards), that would still provide for alien life on millions of planets, and intelligent life on hundreds of thousands of those planets.

Given these facts, the Fermi paradox asks: why do we appear to be alone?

Recent research from the Australian National University in 2016 suggested the reason we may not have found alien life is because any life that may have existed on other planets has died. 

Our survival on Earth, then, is largely down to a mix of planetary quirks and chance. 

Physicist Brian Cox thinks we won’t hear from intelligent aliens anytime soon (if ever) because life forms at that level tend to out-engineer themselves into extinction; destroying themselves by creating more technologies than they have the social and political expertise to manage (does that sound familiar?) 

Cornell Astronomers appear to be on the same page as NdGT, arguing that due to the sheer amount of time it would take extraterrestrial life to receive our signals and respond, it could be around 1,500 years before we hear from any alien neighbours.

At a panel on extraterrestrial life, NASA and SETI representatives pointed out that intelligent alien life may not even have a drive to explore and reach out.

Or that if they do, they may have a policy similar to Star Trek’s Prime Directive, where they deliberately avoid making contact with other civilisations (namely, ours).

Stephen Hawking characterises any first contact as dangerous, and points out that when Columbus came into contact with the populations native to the Americas, they were subject to a dominant culture that possessed superior technology and a world view that assessed them as inferior – something that could happen to us.

Douglas Vakoch, the president of METI International, feels that any civilisations capable of interstellar travel would know about us already, so therefore they must not be hostile.

However, Tyson was responding to the question of our ability to strike out and discover life elsewhere, and his assessment is based on the challenges posed by travelling interstellar distances.

It seems likely that if we progress in our abilities to travel through space faster than he’s predicting, he’ll be happy to have been proven wrong.

Makes sense, from our perspective, but maybe far more advanced civilization that figured out different way to travel through space, and even time and doing so might even be trivial for them.
