tl;dr: Astronomers find signs of concentric circles in the universal background radiation.
If you believe that the universe is cyclic - that there's been a series of Big Bangs starting off each cycle - then this shows there have been many Big Bangs.
If you believe the universe is always expanding, then this shows our universe has bumped up against other universes when they were forming...
Of course, the "evidence" might just be data artifacts. There's a better data set coming soon.

them. Adversaries remain citizens of the same state, common subjects of
the same sovereign, servants of the same law."
