166. Interstellar travel. That's the thing here.

Fri Oct 30, 2015, 04:13 PM

Oct 2015

First, the distances are huge. The galaxy is really, really big. And the distances between stars is really, really large. So I have that going for me in this discussion.

Add the fact that to think about interstellar travel one must consider high velocities, otherwise it is a complete non-starter. Oh! And then we have to start considering time dilation and what the fuck one would do about the atoms impinging on a spacecraft traveling any significant fraction of light speed. Of course, that means shielding, which means more mass. And... We are back to that nasty old rocket equation again, which is where I believe we started.

Sorry! Your case, whatever it is, does not stand.

I sincerely apologize for being impolite and I thank you for your response. However, I must reject it, mainly due to what basic science says. This stuff is physics 101.

My best to you.
