[Star Wars] Does the theory of relativity apply in the SW universe? Do some planets go through time quicker than others?

Since someone here once posted: 

>"One piece of evidence for relativity in Star Wars is that Luke receives all his training from Yoda in the time it takes Han and Leia to travel to Bespin without a hyperdrive.

>That would be consistent with the idea that the Millennium Falcon is travelling at a high sub-light speed, enabling Luke's months of training to coincide with a few days on the Falcon."

Relativity is bypassed by the rules of the Star Wars universe, but it does exist.

The example of Luke training while Han and Leia went to Bespin actually has a much more mundane explanation. As you remember, their hyperdrive was down. They had to travel to Bespin on their backup hyperdrive (much slower) which took them several weeks. 

The reason ships traveling at superluminal speeds doesn't break relativity, and can happen at all, is because hyperspace is a separate dimension that is parallel to our own. The ships access this and use it to travel between points without breaking the laws of physics and to avoid the effects of time dilation.
