And (as you demonstrated) equivalent.

It's too bad, but we are probably stuck with the universe as we know it.

I used to think FTL was required to get around in the universe, but after 
understanding that nanotechnology should be able to keep you healthy for a 
million years at least, slower than light travel will do.  And it has some 
advantages.  Government requires timely feedback.  If you don't care for 
being under a government, a few light years takes care of that problem.
