Scientists have claimed that evidence for past universes may exist in the night sky – namely the remnants of black holes from another universe.
As reported by New Scientist, the idea is based around something called conformal cyclic cosmology (CCC). This is the theory that our universe goes through constant cycles of Big Bangs and compressions, rather than having started from a single Big Bang.
While most of the universe would be destroyed from one cycle to the next, these scientists claim that some electromagnetic radiation could survive the recycling process. Their findings are reported on arXiv.
“What we claim we’re seeing is the final remnant after a black hole has evaporated away in the previous aeon,” University of Oxford mathematical physicist Roger Penrose, co-author on the study and co-creator of CCC theory, told New Scientist.
The evidence comes in the form of “Hawking points”, named after the late Stephen Hawking. He theorized that black holes would emit radiation known as Hawking radiation, and it’s this that Penrose and his colleagues suggest may pass from one universe to the next.
Wow, this is freaky
. What I don't get is, how exactly do they attribute this to a previous universe
?
(Also, if the universe is in a cycle of 'Big Bangs' and 'Big Crunches', then why is the current universe expanding at an ever-increasing rate? Something would have to slow down the expansion, and then eventually cause the universe to collapse back in on itself!)
