As we all know the universe is a vast place. Well in excess of 10 billion light years from end to end. Now according to Einstein one can’t exceed the speed of light. So if you’re like me and don’t fancy spending 10 billion years in stasis just to take your annual holidays on FAsuKtil-B49XZ//\\5.2 (which I hear is really a happening place, albeit a little out of the way) you’re gonna have to get there without actually travelling there (or your particles travelling there if your thinking about Star Trek). But is that possible and if so, how? Any thoughts?

I don't know how often I have repeated this next statement here, but Einstein
never said you couldn't travel faster than light. What he said is this...
any material object within the (this) universe cannot travel AT the speed of light. There are solutions to SR which
require that you must be traveling faster than light and whilst some of the conditions for being able to do so are bizarre compared to what we normally experience (like imaginary mass), they are not impossible physically.
So, to the rest of the question...yes, you can. It's called a wormhole
Now for the size of the universe....10 billion light years is nothing. The universe is actually closer to 94 billion light years across. If you want to understand why it's this big, go
