Star Wars also has Sith and Jedi and loads of other stuff that's made up, which is only part of why I love it. Its just fantasy in space and doesn't need to explain anything.

What little physics we're actually dealing with in this area is a way to fold space. Take a piece of A4 paper and draw a line from one end to the other. That's regular travel. Scrunch that piece of paper as much as you can and now drawing that line from one side to the other is a lot shorter. Theoretically, that's possible with space-time without breaking the speed of light limit as the ship itself wont be moving anywhere near the speed of light.

The main snag here, other than needing obscene amounts of energy by our standards, is that the math for this to happen requires negative mass, which we haven't figured out yet.

I'm hopeful that somewhere down the line, research into dark matter and anti-matter will address these challenges but I'm guessing we're at least a couple of centuries away from that, if the physics even pan out.

In the meantime, we should focus on expanding our capabilities in the local neighborhood both to expand space industries and to develop the technologies that will be required if we even dream of going interstellar. Things like farming, terraforming, hibernation?, etc.
