Well, to be fair (and be Devil's Advocate), the laws of physics won't be changing in a thousand years.
That said, I don't have a problem with the lazors as shown, or the Highway to the Danger-Zone contrails. It's all good.
Thats a big assumption...
Think of all the things that have been discovered and since changed in the last 1000 years.
What is fact today can become false tomorrow. It might not of course, but who is to say that someone doesn't design lasers using a different mechanism which requires more of a light source, just for stupid example.
A thousand years ago I'm not sure people knew what space was, let alone fly in it and shoot something called a laser.
