Singularities, What is Inside a Black Hole and Behind the Big Bang?
Sunday Express reported on the possibility for research in standard Big Bang cosmology into areas before not empirically researched. That point being before the singularity at the moment of creation or the Big Bang as it is sometimes called.
It has been notoriously thought as something outside of the realm of empirical physics and only left to theoretical physicists to speculate and compare with moments of the universe after T=0, when time began — literally came into existence.
One international team of researchers is proposing a different picture of a before of creation, of a time before the Big Bang. Apparently, the singularity of black holes is akin to the Big Bang because the laws of physics appear to break down.
With some complex math and quantum strangeness, the international team of researchers claim the origins of the universe and the center of a black hole can be explained, comprehended, and not seen as a sort of known unknown.
Professor Mir Faizal at the University of Lethbridge in Alberta, Canada and the University of British Columbia, Okanagan in British Columbia, Canada explained, “It is known that general relativity predicts that the universe started with a big bang singularity and the laws are physics cannot be meaningfully applied to a singularity.”
Faizal co-authored the paper with Salwa Alsaleh, Lina Alasfar, and Ahmed Farag Ali. Faizal said that the current theories show the singularities, in black holes and at the Big Bang, are built into the interpretations of the math to make the theories. They follow from the math.
However, if they include quantum effects to remove the singularities, then the standard theories based on work by Roger Penrose, Emeritus Rouse Ball Professor of Mathematics in the University of Oxford and Emeritus Fellow of Wadham College, Oxford, and Stephen Hawking, Director of Research at the Centre for Theoretical Cosmology within the University of Cambridge, can be modified.
Those changes to remove the singularities imply new models. Those old models without the quantum effects to the remove the singularities relied on specific models with problems. One model includes string theory, which, as noted, has its own problems.
Only “very general considerations” rather than a specific model is needed to ‘prove’ the proposal in the paper by Faizal and others. The paper concludes that the centers of black holes do not amount to singularities, but, rather, to empirically testable areas of future research.
“The absence of singularity means the absence of inconsistency in the laws of nature describing our universe, that shows a particular importance in studying black holes and cosmology,” the paper said.
