I understand what you are saying, but the possibility of travelling, a: at light speed, and b: for 600 years +, even if ever possible, would mean that the population problem would overrun us many years before we could act.
The logical course must be to address the problem, not run.

But, I didn't intend a discussion really, I suppose. How can there be one? There's no solution at present even worth considering, let alone spending £10000000 on.
Just thinking in text, really.
