My thinking is that science is not capable of everything and visiting
even the nearest stars is a good example. I do not doubt that millions

but they could not escape being bound by the same laws of physics and
the restraints of time that we are. So it is best to accept that all
must just sit around and ponder the "if we only could" scenario.


Of course, I could be wrong.


Well, I don't know either.

I do think that it's unlikely science will discover a way to travel faster than
light, but I don't know for sure.

As for ways to travel at close to the speed of light, so that we could travel to
the nearest stars in 400 to 4,000 years, _that_ is an engineering problem. It's
not something I have any reason to think science is not able to do. But, on the
other hand, what science may not be able to achieve is to make doing that easy
enough that it would seem to humanity to be _worth_ doing.

So the obstacle there is not what science can do, but how much effort and wealth
we are willing to dedicate to that goal.
