The Navy Says Those UFO Videos Are Real

123. oh I don't agree with that necessarily on the alone forever part

It's certainly a highly difficult prospect, and I don't believe aliens are visiting us currently.

But even if the fastest we ever got was 1/10th speed...we could "island hop" the entire galaxy in a not absurd length of time (about a million years). I suspect we could easily reach half light speed in say I don't know 200-300 years or less? Fusion or solar light sails could both accomplish that. That would cut the time down to about 200K years. Modern humans have already been around 200K years on this planet so that's not as long as you think.

Alpha Centauri would only be 8 years at 50 percent C, 40 years at 10 percent C. You send some 20 year olds and they are 60 by the time they get there. (I'd probably wait for the .5 C ships since they will probably get there first anyways).

Now, will we be around for a million years? well, like I said, we are already 20 percent of the way there...and dinosaurs were around for 150+ million years.

Point being, I agree aliens aren't very likely visiting us, and I agree it's awfully hard to travel interstellar distances...but forever? That's a mighty long time.
