Scientists have found evidence of previous universes in the night sky in the form of leftovers of black holes.

Reported first by New Scientist, this is based on a concept dubbed Conformal Cyclic Cosmology (CCC) that basically says that our universe instead of beginning with one Big Bang actually goes through multiple cycles of it.
When major parts of the cosmos would be destroyed from one cycle to the other, some electromagnetic radiation could survive the recycling process, according to scientists.?
According to one Roger Penrose -- a study co-author who is also a mathematical physicist at the University of Oxford, this is the final remnant after a black hole has evaporated away in a previous aeon.?
The data is revealed in the form of Hawking points -- named after the late Stephen Hawking, who hypothesised that black holes would release Hawking radiation. According to Penrose, it is capable of travelling from one universe to the other.
Researchers are of the belief that Hawking points could arise in the cosmic microwave background that’s leftover radiation from the Big Bang. On this map, Hawking spots would be visible like rings of light, also referred to as B-modes.?

Earlier it was believed that such locations in the CMB were created by gravitational waves or interstellar dust. Penrose and his team, however, believe that their theory could offer a thrilling response and one such Hawking point could have already been discovered by BICEP2 project which intends to map the CMB.
The team explained, “Though seemingly problematic for cosmic inflation, the existence of such anomalous points is an implication of conformal cyclic cosmology (CCC). Although of extremely low temperature at emission, in CCC this radiation is enormously concentrated by the conformal compression of the entire future of the black hole, resulting in a single point at the crossover into our current aeon.”?
