DC Dialogues: A Brief History of Time

NYU DC Dialogues presented, "A Brief History of Time." This event featured a two-and-a-half-hour lecture on basic cosmological theory through the eyes of Professor Stephen Hawking, as presented by NYU's Director of the Center for Cosmology and Particle Physics and Associate Professor of Physics, Matthew Kleban.

This event was inspired by the late Professor Hawking’s monumental publication, A Brief History of Time (1988), and DC Dialogues seek to bring Professor Hawking’s work to a live discussion—a précis on one of the most complicated hard sciences in accessible vernacular, presented in a free, university-level lecture format open to the public.

There aren’t enough Matthew Kleben lectures on YT.

What a lazy cameraman! We didn’t see nearly enough of his slide projections.

The energy which is converted into the gravity wave from the emergent black hole;, Is this gravity wave absorbed by something else or is it ultimately converted to other forms of energy or matter? Is the sum of all gravity waves on the Universe pond the value of the gravitational constant? thus growing with time like entropy?

Yeah those aren't "Gravitational" waves. Those are more closely related to sound waves and electromagnetic waves which you only see the visible or audible part of. There is no Gravity as a force. It's simply the geometry of the earth being a sphere causing everything to fall back towards it's center. It's the same reason why if you traveled in a airplane in one direction why you'd eventually end up back at the same spot. So it's not only slightly curved but it's curved in on itself. Thus you throw an object up and it travels back down towards it's center. To me its that simple. If every point on a sphere is its center, that means no matter who you are or where you are you're ALWAYS at the center of the earth from your own perspective. The heart is at Your center, well the word Earth is a anagram for hEart which you're at the center of.

[AFRoSHEENTARCMICHAEL]

If the stars weren't in their locations and the earth wasnt a sphere we would have never been able to travel around the earth. It's almost as if they were placed that far just so we could navigate the planet. Something to at least consider.

I think in the movie 1 minute in that planet was 1 year but they lost more time because he enter in the black hole love time talks :) great talk to

Funny how they are all avoiding the Electric Universe Theory.

There is your “Grand Unification Theory”. It’s Electricity. There, I said it.

So we're in the middle of observable universe? Is that also true for lets say satellites north of galactic plane? No observable parallax?

Also why " _not_ mention" Zel'dovich and Starobinsky who convinced Mr. Hawking of the existence of Hawking radiation and who actually discovered CMBR and Doroshkevich and Novikov who were the first to publish a paper on it and never got any Noble Prize? Just sayin...

[traciemorell]

I dunno I wrote a poem about gravity. I think it’s easier to understand than all these words you guys use.

[username]

Just program this into Helo and theyll compute all your answers. :)) Who knows. Gotta build bigger telescopes and fewer tanks.

Interesting lecture but is Hawking saying time is moving backwards? Is this a linguistic misnomer because I cant seem to get winning lottery numbers from yesterday? Or is he referring to cosmic scale only which he never mentions? Otherwise I'd win and retire. I'm starting to think we know more about this than physicists. Pure "Alice in Wonderland." Total simulation. An imaginary number. Like rent.

Blasphemy!! Earth is flat, universe is spherical. 19:00 time drift. _Very_ special relativity.
