The laws of general relativity apply to everything on all scales.
However, if you only consider events that are close to each other in
space and time, general relativity makes the same predictions as special
relativity — including the cosmic speed limit c. That means you
will never see something move past you faster than light, but it’s fine
for distant objects to move faster than c relative to you.
