I agree.
I watched one of those real science shows , not the one’s in the former History Channel.
It was said that the energy needed to traverse the distance just between the nearest star using an engine capable of light year travel was so immense that the ship couldn’t carry the bulk load of (nuclear fuel) and travel the distance.
I’m paraphrasing but that’s what I remember. It was just impossible as the physics as we know it.
And the alien people believe in the Roswell incident where a rancher picked up a few pieces of tin foil and turned it into an martian spacecraft.
that the ship couldn’t carry the bulk load of (nuclear fuel) and travel the distance.

What about a zero point drive?
What about a Einstein-Rosen Drive?
