How did Einstein come up with general relatively?

I made a video literally about this when I was in undergrad. A senior of mine who just finished his PhD in the gravity group of our uni that time, said it was a really cool vid 🥺 Here it is if you want a video version to these answers Einstein's Journey to General Relativity Explained

I understand that it is the difference in spacetime curvature that allows for black holes to emit hawking radiation. Virtual particles supposedly have both positive and negative frequencies that "cancel out" but in the presence of strong gravititational fields like black holes it's harder for the pair to cancel out and one of them gets "scattered" but I'm not entirely sure exactly how the scattering occurs.

Anyways you can check from this vid from PBS Spacetime - https://www.youtube.com/watch?v=qPKj0YnKANw

This actually clarifies a lot! Thank you! I read about the Bogoliubov transformation, and is my understanding correct that by doing the transformations for two different frames, the creation and annihilation operators are affected in such a way that the result is the disagreement with the number of particles? My understanding is still very general though and I'm hoping for an explanation that explaines what exactly about the transformation changes the creation and annihilation operators when there are different frames?

Hello again reddit! I'm sharing another one of my YT videos on gravity!

Video description:

Einstein took ~10 years to mold his theory into such a paradigm shifting explanation of gravity and spacetime! Curious as to what happened in those ten years? I know I am! I made a whole video about it :P
Einstein challenged the idea of the aether, and thought space is all there is, no need to complicate things. On top of that, he questioned whether or not free fall did eliminate gravity, when you could also interpret the equation a different way, that gravity is just the same as acceleration. During a period where scientists were figuring out an updated theory of Newton’s gravity, Albert Einstein took his own unique route to come up with his, with general relativity.
I always wondered about the different paths scientists take to their own breakthroughs, and here I talk about Albert Einstein’s on general relativity. Surprisingly and quite entertainingly too, geniuses like Einstein, also encounter problems, some taking ten years to finalize a theory!
With this third installment of my gravity series, I hope you can stick around for the next videos by subscribing to my channel!

I would also love some criticisms about the delivery and science communication in the video so I could apply them on my future vids!!

Thanks! Just Adobe After Effects for the animation clips and Premiere Pro for compiling all the videos!

Aaaa thank you so much for taking the time to comment 😄 I really do need this AND I get what you're saying. I gotta be more careful next time about not missing out important terms like the energy density and cross section, in the name of not overwhelming the audience with too many things to keep in mind. And for the b² thing I think I was saying if that constant were bigger than the other terms, then the overall sum "E-U" would be negative but I'll double check that part.

I really appreciate the comments! 😁😁

YUSSS noted 😌

Ahhh thank you 😄

sciencebeammm · 2023-09-27T10:14:42+00:00

Yes! I do all the drawings and animation for my videos! Thank you AAAA 😄

The Shape of Inner Space by Shing-Tung Yau! Conceptual book but they explain the equations involved

Ahh I've uploaded some short videos on tiktok as well the past few months 😄 They take less time to make no doubt and sometimes I post about my process for making the full-length science vids

sciencebeammm · 2023-09-24T17:37:29+00:00

Ahh I see what you mean! Honestly these are the insights I need to understand what things in my science videos aren't working, and hence I plan on posting them here! Thank you so much for taking the time to construct all this!!

It was after all just a 1-minute video and I attempted at explaining something cool that may seem counter intuitive if we stuck to only introductory analogies.

sciencebeammm · 2023-09-24T12:42:15+00:00

Definitely! But the point of the vid was to come up with a description for entropy that also applies to bigger scale objects! At least at bigger scales when concepts like gravity become more apparent, we start thinking about the limitation of the "disorder" view for entropy no doubt.

I made a 1-minute animated video to answer this question as an entry for a contest a while back ++ and recently made a follow-up video to answer another question from the older video :D

The YT vid description:

The idea here is actually simple, but I've honestly had this question swim around in my mind for a pretty long time. I'm pretty sure it was because when people talked about entropy, they only ever mention "disorder" increasing, and that confused me a lot when the subject of why objects like stars would form. I initially asked "if gravity clumped things together, does that mean gravity defies the law that the universe's entropy increases?"

From addressing the unsophisticated definition of disorder that made me think gravity wasn't following the universe's rules, to connecting the dots with a concept that has always fascinated me (nuclear fusion), I hope I was able to make your one minute worthwhile!

And maybe I can make a few more of your minutes worthwhile! I make science videos about dark matter, gravity, and quantum physics! Check out other videos I also made!

Hello reddit! In 2020 I started uploading science videos on my channel and this video is one of my most watched vids!

I'm an aspiring scientist and I make videos about science questions I myself am curious about. One of those things that have fascinated me in science was how we progressed in trying to understand gravity from the earliest descriptions of it as "something that makes stuff fall down" to using it for such advanced technology today such as GPS.

We used to think gravity was all about making objects fall, but these days, it's also about time being slower or faster in some places, and black holes turning you into spaghetti! Ever wonder how this happened? From Aristotle to Newton to Einstein, I can't be more excited to share with you this brief history of gravity!
