I'd be really impressed if we actually made something go that fast. Look at the last 35 years of space travel advancement compared to computer tech. Space tech is at a stand still.
How fast can we make things go? and what if we run into a speck of dust at that speed.
A speck at that speed would be really noisy, in the vacuum of space that is.
I was stationed at White Sands for a while 30 odd years ago. They were doing laser acceleration/launching of frisbee sized ‘flying saucers’ that had very little mass.
No less than 4 huge and serius diesel generators producing power just for the laser and they could only fire it for a few seconds. If you thought the generators were loud it was insane when the laser fired. Very primitive in the tech but amazing.
