I have seen discussions of universes with different numbers of spatial dimensions, universes without a strong arrow of time, universes with differing physical constants, etc. but I was wondering
(here it comes, you are wondering)
(LOL)
would our universe be substantially similar with a drastically different speed of light?
(and everything else the same, protons and gravity and such)
For instance, if light propagated at 550 km/second ??
Or
if light traveled at 90,000,000,000 km/second ??
And by substantially similar, would there be stars, and fusion, and planets and orbits, and galaxies ?
