    Professor Kendall, I just have to thank you for posting these fantastic lectures. I listen to them all every few months, and they just never get old. I know I'm probably asking a lot, but I genuinely hope you do more of these in the future (although you've already covered just about everything worth covering, in my eyes, but I'm confident there have to be other things unbeknownst to me that I would find just as enthralling)
    Again, thanks and I hope all is well.

      Glad you like them! Yes, there are quite a few subjects I did not touch on. Cosmic rays, exoplanets (ehrmagehrd), planets (in general), space weather, human exploration, robotic exploration of the solar system, advances in the space industry, space policy....

    That animation of the tubes, and the whole video, was as good a description as I've encountered. Good work.

      @@JasonKendallAstronomer Well deserved tribute. If you haven't exceeded your quota of stupid questions, I've never believed gravity needed a force-carrying particle, but what properties would allow it to escape a black hole, if one existed. Sorry, it's what happens when you expose yourself to the world.

    I have seen many videos about ligo-virgo, but the part beginning in 42:50 is new to me, jaw dropping.
    Just to imagine Prof Weiss, planning as a student perhaps the most precise instrument possible nowadays, one which even Einstein said would be impossible to build, and actualizing his plan along 50 years of perseverance, is for me an amazing personal, human, scientific, story and achievement.
    (and to think that Germany, the origin of so much great science, would send him to the gas chambers only because he was a Jewish child, is also a symbolic aspect of Western civilization, which I will never be able to grasp. )

      You've captured it. This discovery is truly astounding.

      @@JasonKendallAstronomer You see, Rai Weiss is just 16 years older than me, and less than 20 years younger from my parents, who also studied in Vienna and had to escape the Nazis, so it is all so real for me, and his genius, nice personality, perseverance, and achievement are so amazing... Also the other members of his staff are such nice people to listen to, the whole thing is of the sort that makes me say, and in spite of all, it is worthwhile to stay around for a little while more, incredible things are still happening. Altogether the dimensions of the modern measurement tools are amazing: The SK telescope in Australia and Africa, the CERN machine, the south pole drills to detect those particles, even something like the James Webb, just to compare it to the ground breaking tool a few hundred years ago, with all respect to Galileo's telescope, -- it is impressing LOL. And never accuse me of under appreciating the great achievements of the past. I adore people like ("people like" ha?) Euclid, Aristo, Kepler, Newton, etc etc to the 19th and 20th century. Still, I am impressed! LOL

    Does this finding support quantum gravity theory? Thank you professor Kendall.

    • @JasonKendallAstronomer
      @JasonKendallAstronomer  4 ปีที่แล้ว +1

      Actually it supports the classical Einsteinian Relativity. There is no need to include quantum gravity to explain the observations.

    Binge watching your lectures, and in your slide "Nearly flat spacetime with a little bump", shouldn't the dr2 term be 1/ (1+ ...)? I think that's what you had in your Black Hole lecture.

    How could the explosion of 2 relatively small black holes be the most powerful event except for the big bang ?

      most powerful *known* event. we don't know about all the other black hole mergers from before LIGO

    warp and woof
    The essential foundation or base of any structure or organization; from weaving, in which the warp - the threads that run lengthwise - and the woof - the threads that run across - make up the fabric: “The Constitution and the Declaration of Independence are the warp and woof of the American nation.”
