    I love NDT, but hate how much he will not even remotely give the idea that it doesn’t have to be Aliens, but a space probe as we humans would send first to study a solar system. We humans sent Voyager, but we don’t want to fathom that aliens would do the exact same thing!! What is wrong with humans?

    When people do these book tours, are they really the author? I mean, did they sit down and write out the whole thing or did someone else write it based on what was said to them and the "author" is just taking credit?

      Professional non-fiction writers will usually acknowledge that they had "help" while writing their books. Namely their editors, publishers,,
      researchers, secondary interviewers, fact checkers, and ,of course, their wonderful colleagues, family and friends. They are, however,
      responsible for the final product . Some famous authors have occasionally been caught "cutting corners" (AKA PLAGIARISM).
      Fiction writers, likewise, sometimes have assistance from others but not to the same degree as the non-fiction writers. BTW if you ever come
      across a book, either fiction or non-fiction by a famous CEO, actor, pop star, or sports icon, etc. you can probaly be assured they got
      lots of "help" (AKA PROFESSIONAL GHOST WRITERS).

      Its a Comedy Show. Colbert has to help Dr. Neil make ASTROPHYSICS both interesting and fun (for the audience) for 10 minutes. They all do
      it...its part of their job.

  • Peter Sage

    Please, Neil; that's a deep rabbit hole, but we've had top neurophysiologists working on it even before Chris Carter codified it in his little TV show. If the aliens are "doing those sex experiments on you" and you aren't fighting them off, you're paralyzed or otherwise restrained. Practically anyone who's experienced hyonogogic sleep paralysis recognizes the feeling of helplessness that comes with it and produced cultural fabrications like alien abduction, succubi, and shadow folk. If you can't move, how you gonna steal that ashtray? I'm serious, Neil: let Alice tie you up in bed, try to stop her from dripping candle wax on your nuts, then imagine asking someone who claims he was abducted by the fair folk why he didn't grab their pot of gold. I'm not saying their claims can't be dismissed without evidence; I'm just saying that if you understand the physiological origin of these claims, you also understand why there can't be any evidence.

    I don't get why neil is so touchy kinda bugs me in every interview he has he touches the person. he does a video with that guy from space time an the guy is talking an neil literaly touched the guys lips an said stop talking lol. an neil said that ship they had on video was more likely to be aliens. Stephen had that all day because there is more evidence showing that there anre aliens than aren't.

    Debunking of Oumuamua's sensational shape - search for a video called "Oumuamua's Rubbish Shape Estimate" on my channel.
    Estimating shapes of asteroids/ comets by studying a tiny flickering dot of light in space (lightcurve analysis) is pseudoscience. The video explains why.

    Mr. Tyson, you don't know if asteroids are loosely held together or solid pieces, in reality. I have heard the loose gravel asteroid theory and somehow that doesn't seem very 'space' to me. You see, our objects in space don't loosely clump if they've got mass. They pound and wedge and compress, unless you have a real reason why not. We have celestial bodies that have greater, equal, or less mass than these asteroids, and many can be considered solid (exceptions due to gas giants, at the least). Your nemesis, Pluto, and his buddy, Charon are both small and solid, so chances are that many of the space rocks that are truly not planets are solid themselves. That is my on-going theory. Now, go get me the funding to send a satellite to determine just how solid (or not) an asteroid is.
