I was pretty sure this theory had been around for a while, but apparently a new study is suggesting that black holes may actually be wormholes leading to entirely new universes. Of course, this being an astronomy and physics theory, there’s little consensus on the validity of the results. Assuming it’s true, maybe we should be thinking about building a warp drive to get us to the nearest interdimensional gateway. But wait – if that’s possible, then there’s a chance that extraterrestrial intelligences have pipped us to the technological post, and are heading our way in a mighty battle fleet! But George Dvorsky says there’s little point spending any time worrying about what to do in the event of an alien invasion – it’ll be over before we know it’s arrived.
