Not sure if this is the best place to post this, but here goes anyway.
While musing about various weirdness recently, I wondered about the following:
Last I heard, cosmologists still refere to the universe has having a size (i.e., light years across). After the Big Bang, and at some point afterwards, the universe's "radius" was less than twice its mass, so the event horizon (so to speak) was outside the confines of the universe. Eventually, the universe expanded, and this "radius" exceeded twice the mass (haven't done any calculations to see when or even if this has occurred yet). So that means one could theoretically escape the event horizon for the universe (to who knows where) on the assumption one could overtake the Hubble expansion.
I know there's something funadmentally wrong with this, but I can't quite put my finger on it.
