Physicist Sean Carroll explains general relativity #science #space #einstein

Einstein did not solve the problem of gravity. He made it a better problem.

My grandfather was the smartest man in the room and whatever room.He was in not because he believed it but because he was. He was unofficially consulted about just about everything going on with World War 2 in 1 way or another.Officially, he was in charge of the Brooklyn.Naval yard because the aircraft carrier's catapult and arresting gear system was his desiand congress in a moment of brilliance assigned him the task. Einstein came up in a conversation when I was about ten years old and my grandfather called him the most brilliant blank idiot he ever met. And I asked him.When did you meet him. He was doing his thing in the broken navy yard when he was called to us.Senate committee meeting to discuss the delivery of a new bomb specifically for blowing up on a target, far far away. He looked at the math describing the effect of the bomb and he said this is not reasonable or possible with conventional explosives.Are you messing around splitting atoms. He was never told yes or no just if it was possible to deliver a five thousand pound bomb to a target and have the plane land on a carrier after delivered. He's like yes.Of course.It is, but the described yields is one tenth of what you're going to be seeing in a typical atomic bomb. They did the little boy test and were horrified to find out that it yielded ten times the energy that they expected. They never told them about that part. The interesting thing is he only had one tenth to formula the yield formula. He went to his grave regretting any work he did for the military spent the rest of his life building houses. You never said why houses. And they never talk science again.

As a visual display of bent space in 2D is a pretty useless way to display what is a 3D issue. I'd be interested in a better visual description of space-time and gravity.

[craiger]

Oh, thank you that was simple did he say!?!?!

[noeldacosta]

That doesn't explain it. That describes it. Not the same thing at all.

[davidhunt]

The passage of time literally slows down around mass, and more so around more massive bodies. Other mass tends to move where time is flowing slower also as there is less potential energy there.

Now why does the presence of mass change the rate of time passing... I have no idea?!??

I, for years had a physics question that people now say the answer is that's what gravity is. I was pretty pissed off because I assumed that Einstein's theory was simply right therefore the answer to my question, could not have been gravity, but it had to be something. Since then I've developed my own theory of gravity. And if I remember correctly a few YouTube comments basically said that this is what gravity is.
I know I'm not saying what it is😅 but to be honest with you I've only recently gotten to the level that I can understand physics equations to some degree and I believe that I have to really look into a few physicists including, Einsteins theories, on a physics formula level just to have a better understanding of what the options are.
But with all honesty I do believe I know what gravity is
And I also believe a lot of people know what it is too but for some reason it's not meant to be common knowledge.
Like Tesla he probably figured out what gravity was, Probably! That being said, what happened to him😮

[The-Singularity-M]

I don't know when this interview was done but I believe that the scientific community has come up with a new theory of gravity, or better yet a different theory of gravity.?

[ross]

But the real questions are what is space time and what is gravity.

[joshk]

"Matter tells space time how to curve, space time tells matter how to move."

"Sitting with a beautiful girl in the park for an hour feels like a minute, sitting on a hot stove for a minute feels like an hour."

A. Einstein

[mikeb]

Time is not relative. Add up all the seconds from the big bang until the last star dies and it will be a precise #. Its not relative, in fact it is already a predetermined amount, set in stone as it were

[davidschneide]

“gravity doesn’t pull on us, it pulls on a 3D fabric of space time that we inhabit…”

[cizzle]

Is the "The particle at the end of the universe" Sean Carroll?

[mansoorkaghaz]

If space is curved it means we are in some universal spider web

[UnravelingtheMystieries-vncg]

Is it just me or is he the spitting image of our boi Elon

[scottjamtgard]

Gravity changes with the size or mass something has right? When changing gravity does that change space time?

[georger]

186, 000 mi./s speed of light. The quantum entanglement says everything is connected at instantaneous speed and that’s not even true outside the headset. We’re starting to work outside the headset that’s like meditation. I do med.

[Pete]

Gravity is a fundamental force, it curves spacetime...not the other way around.

[d.tesneair]

Yeah but is there like a practical use
