Scientists have claimed that evidence for past universes may exist in the Nox sky – namely the remnants of black yap from another universe .
As report byNew Scientist , the thought is based around something calledconformal cyclic cosmology(CCC ) . This is the hypothesis that our universe goes through unvarying cycles of Big Bangs and compressions , rather than having started from a exclusive Big Bang .
While most of the universe would be destroy from one cycle to the next , these scientists claim that some electromagnetic radiation could live on the recycling unconscious process . Their findings are report onarXiv .
“ What we arrogate we ’re seeing is the net remnant after a black hole has vaporise away in the previous aeon , ” University of Oxford mathematical physicist Roger Penrose , co - writer on the study and co - Godhead of CCC hypothesis , told New Scientist .
The evidence comes in the shape of “ Hawking points ” , name after the late Stephen Hawking . He theorise that bootleg holes would emit radiation therapy known as Hawking radiation therapy , and it ’s this that Penrose and his colleagues suggest may pass from one population to the next .
They say that Stephen William Hawking spot could appear in the remnant heat in the universe from the Big Bang , known as the cosmic microwave oven background ( CMB ) . pitch degree would look likecircles of lighton the CMB map , know as B - modes .
Previously theseanomalous pointsin the CMB were thought to be make by either gravitative waves of interstellar dust . But Penrose and his colleagues say their theory could allow for an challenging answer , and one such Hawking point may already have been found by theBICEP2 project , which is aiming to map out the CMB .
“ Though on the face of it problematical for cosmic ostentation , the creation of such anomalous point is an implication of conformal cyclic cosmology ( CCC ) , ” the squad wrote in their paper .
“ Although of passing low temperature at emission , in CCC this radiation is tremendously concentrated by the conformal compression of the intact future of the black-market hole , result in a unmarried point at the crossover into our current eon . ”
The possibility of a recycling universe isnot without tilt . Most of our evidence suggest that the enlargement of the universe isaccelerating , with the universe not beingdense enoughto squeeze back into a single point and enlarge again – sometimes call the Big Bounce theory .
We ’ve alsoyet to findany evidence of Hawking radiation , let alone Stephen Hawking points . So while this is an interesting theory , there ’s plenty more work to do just yet before anyone go about claim the definitive existence of a previous cosmos .
