Thank you Dr. Greene. Stay safe and healthy!

[giovannasculli]

Hello Prof Greene ok we'll be waiting. Take care!

[iam]

Thank u sir !
Will.hv to stay up all night..to catch u live ..and try...asking. Q with a near perfect timing so tht u see it !!🤠

[alnilam]

Indeed: Curveture is to Time as Length to Distance: Thank you ProfGreene!

[jad]

Can you please discuss equations related to Electromagnetic phenomena, such as Gauss's law, Greene's Theorem etc.

[danielbachour]

Looking forward for seeing you tomorrow professor Brian! Amazing video and great explanation as well .. I checked this video out some time ago! I never get tired of watching it!! The bottle of water experiment is perfect, and at the end, the mathematics of General Relativity, a beauty!! Thanks professor!!

[AndrewBarfield]

Please discuss the "curvature of time". Sounds interesting!

[demetrismanikas]

Professor Greene you talked in one of your lectures about how neutrinos may give an answer to why there is more matter than antimatter these days. Is there any math behind it and if so do they treat time as reversible?

[paulc]

The bit at the end of the Stephen Colbert Show was really funny !!

Hi Dr.Greene, in mathematics of General Relativity, What is the Difference between Space dimensions and Time dimension? can we represent Time as a Vector, like we do for Space ???

[martinnyberg]

Could you explain why the standard model has one field for each type of particle, rather than treating e.g. all leptons as different excitations of a single lepton field?🤔

Temperature is the measure of random speed of particles. Let's say we have a box with a gas and it has a given temparature. This means, that the molecules have on aggregate some speed. Then imagine we double the volume of the box, which decreases the pressure of the gas and it's temperature. Now, the question is: since the temperature is the measure of the speed of the gas molecules, and the temperature went down, it means, that the speed of the molecules also decreased. How is it possible by simply increasing the volume of the box? We didn't even touched the molecules. They only have more space, so they collide with each other less frequently, but the speed should stay the same. What's wrong with it?

Tell me if I'm wrong, most of the current mass and energy in Universe was condensed from the inflaton field after a tremendous expansion, so the total energy of the Universe increased. Does this break the first law of thermodynamics of energy conservation? It would be nice if you answer tomorrow, thank you

[RajdeepDhareed]

Eagerly waiting for the next video Professor Greene and also the derivation of Reimann Curvature te nsor.

Professor Greene, I have a question : What is Einstein-Hilbert action ? and What are Penrose diagrams ?

Also Professor Greene could you kindly recommend us a book for General Relativity for beginner/amateur like us with all the details of GR and its Math too ?
Thank you

Hey, could it be possible to make a video discussing the basic math of string theory or some other quantum gravity theory? I have your super awesome book "The Elegant Universe" about string theory, but I can't say that there are many equations in that book. An example of an equation you could discuss is the Wheeler-de Witt equation. I have heard about it, but I have absolutely no idea what it says or how it's derived.

[safirahman]

Prof. Kindly explain superspace also..

[silversamurai-]

Hello sir. I had a question about quantum gravity..as we know, the whole science community has confirmed the idea of general relativity as the theory of gravity.. every theoretical physics fan knows that it has been a huge problem to bring general relativity with quantum mechanics..so my question is that..what are the major problems, we will face if we take quantum gravity as the theory of gravity..why we can't take it as our quantum mechanical theory of gravity?....thank you SIR ..I am Mrityunjoy Medhi from Assam, India

[chiranjibidhakal]

Can you please make videos on Tensor analysis in physics ?
thankyou so much professor for these awesome videos ..i am enjoying alot😊

[MyWissam]

Question to Dr. Greene's Q&A tomorrow: Mass, or more specifically you said energies, are deforming or giving shape to spacetime ... and this includes electromagnetic energy. A charged particle in an electric field, when it moves (oscillates) there is a delay in the reaction of the electric field surrounding it (pertaining to the speed of light) and a deformation of that field... How is this deformation in the electric field related to the deformation of spacetime?

[petkucius]

What time is the live? I dont want to miss it, I got a couple of questions lined up. Cheers.
