(154,021 posts)I played with one type of drive in fiction, that a few physicists said it's also possible. I guarantee both, if all the technical issues, see energy chiefly, are overcome, are not just within lifetimes, but in one case within minutes... It will take half an hour for you to make the translation from Alpha Centauri to Earth... Two hours, calculations needed not to jump into the sun, from a system 50 LY from Earth, such as my fictional Chara II. (The actual Chara system is closer)
I have talked to people who do this thing called particle physics and string theory.
One of them happens to be my cousin, when we rarely see each other we talk of this shit, not because little green men are visiting, but because we will need to leave the solar system or go extinct. What pray tell you tells you other intelligent species did not, or are not, having the same needs? Stars have finite fuel up you know. Any intelligent species will understand the life of stars once it reaches a certain tech level.
But right now we can, theoretically mind you, cross interstellar space with our current tech base. Oh and building a gen ship would take the World's GNP for a generation. I have no idea, neither do you, if we survive technological adolescence, if and when we will develop possible FTL.
Anybody who has, is way ahead of us. So earth is visited (if at all) for research in a benign way, or scouts to strip it of resources.
