“Black holes are mathematical solutions to the Einstein equation,” Giorgi says — the “master equation” that is the basis of the general theory of relativity. She and other mathematicians ...

Crucially, this bounce occurs entirely within the framework of general relativity, which applies on large scales such as ...

The 81 squares in the grid correspond to vertices in a mathematical graph. A line connects vertices that appear in the same row, column, or subgrid. This translation allowed the mathematicians to ...

Holographic duality is a mathematical conjecture that connects ... So inside the shape of a black hole, for example, gravity exists in three dimensions while a particle theory exists in two ...

has given rise to mathematical structures of relevance to measurable physics far from the rarefied realm of strings. A visualization of two black holes scattering off each other and emitting ...
