Neil deGrasse Tyson on UFOs, Government Files, and the Physics of Alien Claims

Until you show me an alien, it's a belief system. So what is your answer to the Feremy paradox? Where's everybody? Assuming they're not here yet. The one that I like best is the one that has geopolitical implications. And this w was first put forth by Steve Soder, a colleague of mine. It has to do with I let's say you do figure out how to Colonized planets. So the way you would do it is you launch a rocket from one planet, it goes to another planet, and then you make two rockets, then you launch to two planets from there. And each of those m builds two rockets and then you do so it doubles. Okay? There's not many doubling times.

Before you can completely populate one hundred percent of the planets in the galaxy. You could do that in a much smaller time than the lifetime of the galaxy itself. So where are they? So the argument is the primary reason why anything is classified is uh especially with regard to equipment, is so that our enemy adversaries do not know the precision with which we can make an observation or a measurement. It's not that we have some craft that is completely unknown or un it's it's generally it's the specs on the thing that was designed that gets classified. Just so people know. The laws of physics That nowhere in the universe where we have seen matter and energy interact have there been a violation of these laws. So we have no expectation that an alien of this universe is violating physical laws routinely. Period.
