    Our lone galaxy is 100,000 light years across. Just ours. In a sea of an uncountable number of galaxies.

    I have no doubt that there is other life out there. But we’re so far away from anything.

    Our tiny minds (mine included) can’t even fathom the scale of our universe. And to the best of our current knowledge there’s no getting past the speed of light. So it’s 100,000 years to cross this one galaxy at the currently understood peak of what we might be capable of centuries from now.

      And to the best of our current knowledge there’s no getting past the speed of light.

      An important point that I rarely hear discussed, “to the best of our current knowledge”.

      This is the key point, putting our current limitations due what we currently understand (and don’t understand) about physics and science in general, and placing those limitations on a potentially more advanced intelligence, does not satisfy me at all.

      If they exist, and are more advanced, then by definition of “more advanced” they will know more than we do, otherwise they wouldn’t be more advanced. We can’t know what that is until we discover it ourselves or they tell us.

      200 years ago we got around on horses or walking. 100 years ago we still hadn’t split the atom yet. We could still be like toddlers of scientific discovery.

      In the end you could be right, the speed of light could be a final unbreakable limit. Could be wrong though and we won’t know until we do.
