The expansion of spacetime became so fascinating after one of the astronomers on the โThe First Secondโ episode of HTUW explained how faster-than-light expansion was possible. Nothing can move through space faster than light, but the fabric of space itself can. That revelation blew my mind!
This reply above is pretty much correct. All motion is relative, so everything moving relative to everything else. But the universe itself- spacetime - is expanding, and everything see that as them being in the center of the expansion. www.youtube.com/watch?v=9B7I...

Spectral methods are very efficient for modeling BBH spacetimes because the spacetime metric is smooth. But we also need to be able to parallelize our problem so it can run on larger supercomputers. Thatโs where discontinuous Galerkin shines. 3/8
