As far as _we_ know. Till some time ago we did not knew about relativity. P.S. It's really funny to see forbes as a source of science.

  If we’re going to seriously discuss things we don’t know, and have reasons to believe aren’t possible, where are the boundaries? What if advanced civilisations asked fairies to take the messages for them?

    I'm always a bit skeptical about physics because whatever models we find and celebrate now will have to be adjusted at some point in the future. I wonder if there's any way of knowing that something is indeed impossible or if our model of something is final and set in stone. I'm happy there are at least some universal constants like absolute zero or the max possible temp or planck length. And as for anything FTL, I hear it breaks the rules of causality and that seems to be a big no-no and is indeed impossible.

      >I'm always a bit skeptical about physics because whatever models we find and celebrate now will have to be adjusted at some point in the future... The physics we have at any given time is tested through experimentation, and has proven effective and accurate to some degree. Within those parameters it's verified. So skepticism of current physics makes sense to a point, we know it's not complete, but we also know that in a massive range of many complex and sophisticated tests it turns out to be precisely accurate. That's got to count for something. Testability is a strength not a weakness, it means we know for sure what the limits of our understanding are. Outside the domain of science we have no such heuristic, so we have no idea whether or to what extent anything we think up bears any relation to reality whatsoever.
