My Romance with Caltech and with Black Holes - Kip S. Thorne - 2/27/2019

[@haroldfloyd5518]

I love listening to Kip. I’m sure I don’t understand what he’s talking about, but he makes me feel like I do. And he has a way of springing mind boggling ideas on you that I also enjoy.

U love cats ? They are very nice pets. Some people have lots of pets.

Excellent presentation and discussion on the work of a great scientist. Thanks for posting!

[@coastwalker101]

Super talk, especially the potted history of black hole theory. I had never really understood what frame dragging was but got it the moment he showed the graphics illustrating how it comes about. Thanks! Like many I bought the Telephone Book back in 1981 despite not being able to do most of the mathematics it requires, it is still a great read.

[@dancooper8551]

Excellent presentation. Just another reason I’m setting up a scholarship fund for Caltech Ph.D students.

Einstein was proven both right and wrong with LIGO. Right with that relativity was the real way the universe was structured. Wrong with that Einstein believed we would never be able to detect gravitational waves, and we did. Kip Thorne is one of the best physicists that have ever lived.

This is an excellent presentation!

[@brainstormingsharing1309]

Absolutely well done and definitely keep it up!!! 👍👍👍👍👍

Great lecture from a great physicist. I can't help wondering though, how anything can move past or through the event horizon, when time has stopped there. If time stops then there can be no events and no motion. Seems like they've overlooked this?

[@jeanqnguyen4542]

(not a physicist) My little understanding of Gravity is the warping of spacetime, spacetime switch places beyond the Event Horizon

[@KonBlo]

Time stops there according to the external observer's perception of reality. What actually happens inside the Event Horizon is a whole different story which cannot YET be described by the Maths of this poor planet.

[@TheBinaryUniverse]

Exactly. They're just guessing. It all hinges on whichever of two interpretations is correct. The mainstream view is that although time at the EH stops relative to us, they go on to assume that time carries on somehow within the frame of reference of the EH. Meaning they view time as purely relative. But they don't know what time is so they are not entitled to make this assumption, at least, not without considering the alternative. The alternative is that time is relative, sure, but it is also finite. When it runs out, it runs out in absolute terms, in which case, all events stop at the EH, not just from our point of view, but also the frame of reference at the EH has become frozen, indefinitely. This hinges on the interpretation of Special Relativity which is where this "purely relative" view of time originates from. I resolve this complex issue (along with many others) in my book, "The Binary Universe" - A Theory of Time.

[@eden8426]

Time doesn’t stop past the event horizon, it stops at the end of a black hole as we call it the spacetime singularity. Something beyond the laws of our physics put forth space and time to come to a complete stop. Maybe some research into Hawking radiation might help you understand a black hole better.

[@eden8426]

Matter in a black hole has collapsed to such a high energy density it creates a very strong gravitational field surrounded it. The reason nothing can escape not even light is because the event horizon is traveling at escape velocity.

[@Oceansideca1987]

Keep on keeping on Kip

[@whirledpeas3477]

I absolutely want to believe that after QM there is something that will help humanity. Sometimes I think that it's just like seeing how far we can push Pi.

[@keybutnolock]

Great talk. and a nice Willy Nelson impression !

[@sumanthravikumar4585]

I understood a lot about Caltech and gravitational waves after seeing this video

[@TMPreRaff]

That's the video title of the year.

[@jonathanhoodstock4484]

I would love to smoke a joint with this man and I think he will enjoy it too :) Thank you for keeping me busy during this lockdown Kip, I love your videos they make me tripping a lot. Cheers from Italy

11:37 does bad memory have any advantage? it cause you to figure out one topic several times with several different ways! cool

[@adzz8012]

Cygnus x-1 and a certain year long subscription should have played into this convo 🤣

[@merlepatterson]

Can a thing really exist at a detectable and visibly representative point in space and time which is said to have no time quantity in and of itself if it can also effect surrounding bodies of orbiting gas, dust and stars in its detected point location in space time? If there is no time quantity to a thing, does it (can it) exist as an influential body to surrounding objects observing or orbiting it via its effects in non time dilated space time? One might think if there is no 'time' quantity to a singularity that there would also be no 'time' for it to have effects on surrounding bodies and therefore be 'time invisible'.

The lecture was to long. A good length of time would of been 30-45 minutes.

[@LavenderTown40]

Most colloquia and lectures I've been to averaged around an hour.
