An older universe existed before the Big Bang, and
proof for its existence can still be found in black holes, according to a Nobel
Prize-winning physicist. Sir Roger Penrose made the assertion after receiving
the award for advances in Einstein’s general theory of relativity and proof of
black hole existence. Sir Roger contends that inexplicable regions of
electromagnetic radiation in the sky, known as ‘Hawking Points,’ represent vestiges
of an earlier universe.
It is part of the “conformal cyclic cosmology”
universe hypothesis, and it is proposed that these spots constitute the final
outflow of energy known as “Hawking radiation,” conveyed by black holes from
the older cosmos. A black hole is an area of space where stuff has collapsed on
itself and has such a strong gravitational pull that light cannot escape. Such
an event could be happening at the centre of our galaxy; Reinhard Genzel and
Andrea Ghez, who shared the Nobel Prize with Sir Roger, provided the most
compelling evidence of a supermassive black hole in the centre of our galaxy.
There is a chance that the timescale for a black hole’s complete evaporation is
longer than the age of our present universe and hence cannot be detected.
Many people have criticized the theory, and the
existence of the type of radiation emitted by these black holes has yet to be
proved. Furthermore, since an infinitely vast universe in one existence must
become an infinitely small cosmos in the next, all particles must lose mass as
the universe ages, a concept that has also been received with skepticism.
According to conventional cosmology, the cosmos experienced a brief expansion
or ‘inflation’ following the Big Bang, which would have removed anomalies in the
universe’s structure. Sir Roger said that black holes were likewise disregarded
as simply being in mathematics until their reality was proven.
