How to Make a Simulation Wall Transparent
Every computer model of a black hole runs into the same inconvenience. A machine's memory is not infinite — at some point you have to cut off the calculation, as if placing a solid wall across space.
Digital Conductor of Gravitational Waves: Neural Network Conducts Black Hole Mergers
In September 2015, two four-kilometer laser beams compressed by a thousandth of a proton — the LIGO interferometry detectors caught a gravitational waves for the first time. Its source turned out to be the merger of two black holes 1,3 billion light-years away.
