Exploring String Theory at Black Holes & Universe Expansion

Click For Summary
SUMMARY

String theory aims to reconcile the conflicting principles of quantum mechanics and general relativity at black hole singularities and during the universe's expansion. It proposes that singularities do not exist in their traditional form but rather as extremely small, entangled structures known as "string balls," which preserve information. Additionally, string theory supports the notion that dark energy is responsible for the universe's expansion, with no compelling alternatives currently prevailing in the field.

PREREQUISITES
  • Understanding of quantum mechanics principles
  • Familiarity with general relativity concepts
  • Basic knowledge of string theory fundamentals
  • Awareness of dark energy and its implications in cosmology
NEXT STEPS
  • Research the mathematical foundations of string theory
  • Explore theories on black holes as "string balls"
  • Investigate the role of dark energy in cosmic expansion
  • Examine current debates and alternatives to dark energy in cosmology
USEFUL FOR

Physicists, cosmologists, and anyone interested in the intersection of quantum mechanics and general relativity, particularly in the context of black holes and universe expansion.

Hey, does anybody know what the string theory tries to prove at singularities of black holes and the expansion of our universe?

I believe, and I'm no physicist so don't trust much I say, but I believe that string theory is trying to show that in black hole singularities that are incredibly small (quantum) and incredibly massive (general relativity) that the two are somehow not at odds, and can be combined into one theory, because normally they are at odds and that's why singularities like the Big Bang and the Black Hole ones make no sense.
 
a few quick notes:

(A) string theory imposes minimums and maximums on size. A minimum size implies no exact singularity, but rather something very small istead. A few in the field have advanced theories of black holes that look more like places for strings to get caught and entangled together in giant "string balls" almost. This allows for information to be preserved, which even people like Hawking are now admitting seems accurate.

(B) I believe in string theory, dark energy still acounts for the expansion of our universe. I think some alternatives have been proposed, but so far the majority still feel dark energy makes the most sense.

(Note, I only have a bachelor in physics, and haven't yet studied string theory mathematically - only conceptually through articles/books/etc. Anyone is free to correct my comments on it.)
