The multiverse is so crowded that universes bump into each other. We need to move our universe out into a rural part of the multiverse so we can get some peace. Background cosmic microwave radiation provides evidence of whole universe collisions?
Now Stephen Feeney at University College London and a few pals say they've found tentative evidence of this bruising in the form of circular patterns in cosmic microwave background. In fact, they've found four bruises, implying that our universe must have smashed into other bubbles at least four times in the past.
We are just a bubble floating around in the multiverse?
Are there any causally identical universes which are ahead or behind us in time?
