Now gravity I can get my head around. Electromagnetism, not so much.

Gravity affects light, hence black holes.
An explosion can only happen as fast as waves can propogate through a medium. That will be the local speed of sound. If gravity affects light, I imagine it affects sound, too.
I'm sure I read somewhere that it takes millions of years for a radiated particle emitted from the centre of the sun to emerge at the surface.
