On time, read Einstein. See: relativity, special and general. There's a reason it's called spacetime and not just space.

Because time is not something separate, but tied to the fabric of spacetime and the movement of light, in parts of the galaxy where gravitational effects get wonky, you'll get such weird features as time dilation. Even in normal conditions, somebody traveling at 99% the speed of light will experience "time" as passing slower than somebody traveling at effectively 0% the speed of light. There's a classic thought experiment demonstrating this.
