[pbqmidor] 4D science

How would science be different if we lived in a 4-dimensional universe instead of 3?

Astrophysics would probably be very different, especially objects rotating and orbiting.  Probably Maxwell's equations and general relativity would behave significantly differently.  Linear motion would stay the same.  It might be much harder for particles to collide for nuclear fusion because there is more space to miss.  On the other hand, gravity will keep compressing to compensate.

Chemistry: geometry of electron orbitals, steric effects (steric hindrance).
