Yes, I understand that, that's why I'm asking not if such a thing is _possible_ but whether it is even remotely _likely to exist_, given what we know about the universe, how galaxies and stars came to exist, etc. That is, in order for something to have this immense energy in our frame of reference, that something (or Earth) would have to get that energy somewhere. What I'm asking, essentially, is how likely is it that such conditions would exist at some point?
