Many years ago I attended a talk by Richard Feynman. It was as much of a highlight of my life as seeing Jimi Hendrix.
Anyway, Feynman at one point was asked what he thought of UFOs. He stated that he firmly believed it was impossible to exceed the speed of light so interstellar travel was unlikely. He did, however note that most of the reported sightings could be just as easily explained by time-travel. He said that there was no such thing as yet but that time travel did less violence to physics than faster-than-light travel.
Who knows? UFOs could be our distant descendants coming back to take a look
True.
Speed of light supposedly limited by mass—the faster you travel the more massive you become and at speed of light you have infinite mass, can’t accelerate an infinite mass. Trick would be to isolate your mass so your mass never becomes infinite.
I’m no physicist so I may be wildly wrong.
Anyway, maybe someday we will either crack faster than light travel or time travel.
The speed of light issue is so yesterday.
Use the super-duper wormhole generator energy machine and you can go anywhere in the universe faster than you can say “Congressional hearing”....
