In the beginning, there was chaos.
Hot, dense, and packed with energetic particles, the early Universe was a turbulent, bustling place. It wasn’t until about 300,000 years after the Big Bang that the nascent cosmic soup had cooled enough for atoms to form and light to travel freely. This landmark event, known as recombination, gave rise to the famous cosmic microwave background (CMB), a signature glow that pervades the entire sky.
Now, a new analysis of this glow suggests the presence of a pronounced bruise in the background — evidence that, sometime around recombination, a parallel universe may have bumped into our own.

Reading theories like these always make me wonder, what happens if two universes collide directly? What is the "skin" of the universe that separates it and protects it from glancing blows from other universes? What's the medium universes are moving into smack into eachother? Is it dense, is it sparse and this supposed collision was just one in a bajillion chance? Can we expect universal level dinosaur destruction when a universe meteor smashes into our universe? Will universal Bruce Willis have to leave our universe for multiverse space with his rag tag universal drilling crew to blow up the universal asteroid before it smashes our universe? This idea just evokes so many questions.
