This background is especially relevant as E=mc2 does not necessarily work in all parts of the universe:

A hundred years ago, Einstein’s General Theory of Relativity broke physics. After putting the pieces back together with the new rules, physicists saw that not everything was working as expected. For one, some galaxies were spinning around each other faster than they should. Since that speed would be a function of mass, the only way to reconcile the discrepancy was to posit the existence of invisible, heavy particles. Lots of them. Like, 75 percent of all the matter in the universe.

In the video simulation, gamma rays are the glowing dots gathering en masse on the left side of the black hole. “On the left side it’s really spacetime itself coming towards you, sweeping along all these gamma rays,” says Schnittman. It’s impossible for anything to move against the flow of spacetime.

We hope you like the video and that astronomers and physicists keep pushing the envelope with new tests, theories and apparatus to study the universe.
