I think interstellar travel is very feasible. But not for humanoids as such without modifications. If we start traveling to distant planets, it will be by robots, robotics and AI. Not in human form or human beings as we know them. Perhaps we become genetically improved to survive in space, then again, maybe not. My bet is with AI and robots. Perhaps even a human brain transplant into a robotic body. Who knows? We do have the technology today to plug a human brain into a robots body, but not the transplant yet.

I do firmly believe that if humankind is to survive as a species, it must leave this world and begin colonializing other planets. We’re a sitting duck for another asteroid or comet hit like the one 65 million years ago or the eruption of a super volcano, nuclear holocaust, draught, ice age and more. Maybe some cockroach who survived one or more of the above, which evolved into an intelligent being will be studying the fossilized remains of us like we study dinosaurs.

It's high past time that we start electing Americans to congress and the presidency who put America first instead of their political party. For way too long we have been electing Republicans and Democrats who happen to be Americans instead of Americans who happen to be Republicans and Democrats.
