I was always a firm believer in space travel until I finally read just how far the next ANYTHING is and--how much fuel and time it would take to reach there.
The only choice is to put people into some kind of non-aging hibernation for 400 years to get to the next ANYTHING.
Or we have to discover a new source of fuel. Solar energy is WAY off in the future. At least, that is the latest stuff on space travel. We are just TOO FAR AWAY from everything.
I think that there's a reason for that.

What's mind boggling is that not only is there plenty of "space" or distance or whatever, "out there," "here" is mostly empty space too.
If the nucleus of an atom is the size of a golf ball, the closest electron is a mile and half away.
