New Maps of the Bizarre, Chaotic Space-Time Inside Black Holes | Quanta Magazine

Physicists still believe that if they can come up with a coherent explanation for what actually happens in and around singularities, something revelatory will emerge.

In the late 1960s , some physicists speculated that singularities might be surrounded by a region of churning chaos, where space and time haphazardly grow and shrink.

These “dynamics are supposed to be a very general phenomenon in gravity, but it’s something that fell off the map.”.

Relativity holds that two regions of space can be disconnected, meaning that nothing that takes place in one region can have any possible effect on the other.

In the presence of strong gravitational fields, such as those found in and around a black hole, these fields slow down the flow of time so much that interaction becomes impossible.

Stanford students set out to use the correspondence to find out what happens to an AdS black hole.

After Hartnoll first found BKL-like chaos in AdS /CFT, others have been trying to figure out what, exactly, causes it to arise.

Oling has shown that it arises even in a toy black hole model where the speed of light is set to zero .
