Thanks, I am not far off in the book, and I recognize tensor calculus just shown to me in a different notation, and more complicated way i.e Kronecker delta. It's intimidating.
I desire to read General relativity by Wald. I am a student who is self teaching, and I know tensor calculus by Pavel grinfield's introduction to tensor analysis and calculus of moving objects. The book states things from advanced calculus. Do I have more math to learn before hand?
If I had a small clump of clay and gave it a spherical orientation adding more clay a.k.a mass to the sphere would increase its circumference. As we both know, curvature becomes more intense as circumference decreases. Therefore, bigger cicurmference compared to increase mass will decrease...
Since a black hole goes to a singularity, theoretically wouldn't added mass to that point decrease the spacetime curvature by increasing of the circumference, and then not have a loss in information.
Since black holes takes matter to a singularity, theoretically could there be a hole that does the opposite? As in push everything away like negative pressure.
I understand what you guys are saying, thank you. Medical physicist could be a possibility with me, as for engineering, I'm not much of a fan. All this made me reflect what should I do with my life.
So I know relatively close to nothing on topology... Just the very basic... From a set of videos part of a general relativity course on YouTube by something winter school. I can post the link if you'd like.. I know I sound like some ignorant kid messing with something out of his reach, but I...
Oh my fault... I meant yes as in the sense yes for understand wald... I don't know any of that stuff... Topology I know is the very basics like charting ithe original into a image by taking open subsets of the original and lowering the dimension... Practically the first few pages of wald's book...
