Astronomers Find First Evidence Of Other Universes

via Technology Review

Our cosmos was “bruised” in collisions with other universes. Now astronomers have found the first evidence of these impacts in the cosmic microwave background
Eternal Inflation

There’s something exciting afoot in the world of cosmology. Last month, Roger Penrose at the University of Oxford and Vahe Gurzadyan at Yerevan State University in Armenia announced that they had found patterns of concentric circles in the cosmic microwave background, the echo of the Big Bang.

This, they say, is exactly what you’d expect if the universe were eternally cyclical. By that, they mean that each cycle ends with a big bang that starts the next cycle. In this model, the universe is a kind of cosmic Russian Doll, with all previous universes contained within the current one.

That’s an extraordinary discovery: evidence of something that occurred before the (conventional) Big Bang.
