Sounds like you think that 100% of what's in all the physics books is 100% accurate.
I'm sure the scientists before Gallelio sp? felt that way, too.
It's suchhhhhhhhhhhhh an IMPRESSIVE perspective.

Not at all. But even to this day we can only get electrons to accelerate to 99.99999% of the speed of light. It very much appears to be asymptotic.
“An engineer will tell you that it's an absolute ... like the firmness of the earth.”
Well, that was conjecture. No math to support the assumption.
When we break the speed of light barrier, I will adjust my ideas. Could it happen? Maybe. But Star Trek and Star Wars and warp speed and hyperspace are still science “fiction.”
Personally, I think the universe is teaming with life. Where conditions allow, life will occur. Whether such life is as advanced as we are can't be said for sure. Whether they can visit us or not can't be ascertained either.
Either way, the axiom still holds. “Extraordinary claims require extraordinary proof.” - Marcello Truzzi
