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

String theory is a theoretical framework that attempts to reconcile quantum mechanics and general relativity. It proposes that the fundamental building blocks of the universe are not particles, but tiny, vibrating strings. These strings interact with each other and create different particles depending on their vibration pattern. String theory also suggests that black holes and universe expansion are influenced by the behavior of these strings.
In string theory, black holes are formed when a large amount of matter collapses into a singularity, which is a point of infinite density. This singularity is surrounded by an event horizon, which is the point of no return for anything that enters it. String theory suggests that at the center of a black hole, the matter is transformed into strings, and the behavior of these strings determines the properties of the black hole.
Yes, string theory offers a possible explanation for the expansion of the universe through the concept of branes. According to string theory, the universe is made up of multiple dimensions, and our universe exists on a brane (short for membrane) that is expanding. As the brane expands, it carries matter and energy with it, causing the expansion of the universe.
String theory predicts that black holes have a temperature and emit radiation, known as Hawking radiation, due to the interaction of the strings at the event horizon. It also suggests that the entropy (or disorder) of a black hole is proportional to its surface area, rather than its volume, as predicted by classical physics.
Currently, there is no direct evidence to support string theory's predictions. However, there have been some indirect observations, such as the detection of gravitational waves, that are consistent with the predictions of string theory. Further research and observations are needed to fully test and validate the theory.
