Interstellar Flight: Perspectives and Patience

Won't dreams stay dreams?

There's literally nothing there, why go all that way? The distances are so incredibly vast. It seems like we ought to be content with staying put.

All life on Earth is going die. Humanity has never been content with staying put, why would we start now? And what do you mean "literally nothing there"? The universe has a loooooot of stuff in it.

To quote Babylon 5

Ask ten different scientists about the environment, population control, genetics, and you'll get ten different answers, but there's one thing every scientist on the planet agrees on. Whether it happens in a hundred years or a thousand years or a million years, eventually our Sun will grow cold and go out. When that happens, it won't just take us. It'll take Marilyn Monroe, and Lao-Tzu, and Einstein, and Morobuto, and Buddy Holly, and Aristophanes, and - all of this - all of this - was for nothing. Unless we go to the stars

And those stars will go out as well.

Well true.

That's the fallacy in the given argument.
