Question

explain string theory?
what is a spinning black hole?​

Answer 1

$\huge{\underline{\underline{\mathrm{\red{AnswEr}}}}}$

Fuzzball theory replaces the singularity at the heart of a black hole by positing that the entire region within the black hole's event horizon is actually a ball of strings, which are advanced as the ultimate building blocks of matter and energy.

Rotating black holes are formed in the gravitational collapse of a massive spinning star or from the collapse or collision of a collection of compact objects, stars, or gas with a total non-zero angular momentum. ... In late 2006, astronomers reported estimates of the spin rates of black holes in The Astrophysical Journal.

• String theory is a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects called strings. String theory describes how these strings propagate through space and interact with each other. Thus string theory is a theory of quantum gravity.
• A rotating black hole is a black hole that possesses angular momentum.
