Last week, we looked at this article on the quest for validation of a multiverse hypothesis. If each universe in the multiverse is physically distinct, they might interact with each other. Those interactions could leave telltale patterns in the cosmic background radiation. (Cosmic background radiation is an energy signal from the early days of the universe; it's basically our universe's very first baby photo.) Find those patterns -- circular impressions, like you get when two bubbles bump into each other -- and you … [Read more...] about Science in Review: Avengers Annihilate!
