My work indicated that if we consider smaller and smaller black holes, at some stage, the properties of black holes become indistinguishable from those of elementary particles.

I work in string theory. This is a branch of physics which assumes that the elementary objects in the universe are not particles but one-dimensional objects, that is, strings.

One of the main successes of string theory is that it has been able to unify the general theory of relativity, which describes gravity, and quantum mechanics.
