According to Sir Roger Penrose, there will be other Big Bangs in the
future. Sir Roger Penrose, an Oxford-based mathematician and physicist who
recently won the Nobel Prize in physics, claims that our universe has
undergone multiple Big Bangs and that there is still another one
coming.
Version 2.0 of the earlier article.
Albert Einstein's general theory of relativity was proved and expanded by
Penrose's mathematical methods, and he also received the Nobel Prize in
Physics for his research on black holes, which showed how objects that
become too dense are gravitationally collapsed into singularities, or points
of infinite mass.
Penrose reiterated his confidence in "a crazy notion of mine" that the
cosmos would continue to grow until all matter decays as he accepted the
Prize. Then, a new universe will be created by a second Big Bang.
In an interview with The Telegraph, Penrose asserted that "the Big Bang was
not the beginning." We shall have something in the future because something
existed before the Big Bang. What evidence does the scientist have to
support this alternative to the Big Bang hypothesis, which he calls
"conformal cyclic cosmology" (CCC)?
He claimed to have located six "warm" sky regions, each around eight times
the size of the Moon (called "Hawking Points"). They are named after
Professor Stephen Hawking, who proposed the idea that black holes "leak"
radiation before dissipating. Finding such holes is highly unlikely because
it may take more time than the 13.77 billion years that our universe has
existed.
Hawking collaborator Penrose (89) thinks we can observe "dead" black holes
left by earlier universes or "aeons." If verified to be accurate, this would
support Hawking's ideas.
The physicist found "anomalous circular patches" in the CMB that had high
temperatures in his 2020 study, which was published in the Monthly Notices
of the Royal Astronomical Society. The spots were found using information
from the Planck 70 GHz satellite, and up to 10,000 simulations were used to
establish their existence. In his article from 2018, Penrose discovered
radiation hot spots in the CMB that could be brought on by black holes that
are evaporating.
In a 2010 paper, Penrose and Vahe Gurzadyan of the Yerevan Physics
Institute in Armenia found evidence in favor of cyclic cosmology in the
uniform temperature rings of the CMB. At the time, the scientists suggested
that the rings were created by gravitational wave traces left behind by
merging black holes in an earlier universe.
Cosmologists disagree on these points of view, with some citing the
difficulties of going from an infinitely huge universe in one eon to a
super-small one in the next. This would indicate that all particles lose
mass as the universe gets older.
Here
is Penrose's
most recent
article, "Apparent evidence for Hawking points in the CMB Sky."
For still another intriguing notion,
look at Penrose's theories
regarding the quantum-level beginnings of human awareness.
