But maybe there was a universe before the Big Bang…

From ScienceDaily:

Although for five decades, the Big Bang theory has been the best known and most accepted explanation for the beginning and evolution of the Universe, it is hardly a consensus among scientists.

Brazilian physicist Juliano Cesar Silva Neves part of a group of researchers who dare to imagine a different origin. In a study recently published in the journal General Relativity and Gravitation, Neves suggests the elimination of a key aspect of the standard cosmological model: the need for a spacetime singularity known as the Big Bang.

In raising this possibility, Neves challenges the idea that time had a beginning and reintroduces the possibility that the current expansion was preceded by contraction. “I believe the Big Bang never happened,” the physician said, who Works as a researcher at the University of Campinas’s Mathematics, Statistics & Scientific Computation Institute (IMECC-UNICAMP) in Sao Paulo State, Brazil.

…

Black holes are the starting point of Neves’ investigations about “Bouncing Universe.” “Who knows, there may be remains of black holes in the ongoing expansion that date from the prior contraction phase and passed intact through the bottleneck of the bounce,” he said. Paper. (paywall) – J. C. S. Neves. Bouncing cosmology inspired by regular black holes. General Relativity and Gravitation, 2017; 49 (9) DOI: 10.1007/s10714-017-2288-6 More.

“Who knows, there may be” is not a promising beginning for a thesis in science but so much of current cosmology seems stuck there, mainly for philosophical reasons.

Comments
My understanding is that the stuff that existed the instant BEFORE The Big Bang was so completely destructificated that NOTHING could possibly have survived containing information about that preceding instant. For example, our universe, the only one we will ever experience or be able to take measurements on, was so completely WITHOUT complexity that it had to MANUFACTURE Helium out of Hydrogen. So, any extended discussion about what existed BEFORE The Big Bang is not merely Science Fiction. It's Fantasy. And I enjoy competent Fantasy as much as the next guy. But I can't see any useful SCIENTIFIC discussion of exactly what the elves and fairies were doing just before THEIR universe was crushed down into Primordial Soup. Now from a Theological standpoint, we can speculate on how many times The Designer took a whack at building a Universe. And many ancient religions in fact claim that Earth and our Universe were NOT the original Creation. Ya kinda build a Mark 0 intergalactic sand castle, and it falls down. So you try the Mark I, which is a clear improvement ("improvement" of course depending on your design goals), but still falls down. And when you get to Mark VI or Mark VII, it runs stably for eons. But the guys in the back room are still talking about doing the Mark VIII, which not only has air conditioning and stereo, but will even have Cruise Control.vmahuna

Guessing and speculative statements don't seem derived from knowledge, but from lacking it.
"In a study recently published in the journal General Relativity and Gravitation, Neves suggests the elimination of a key aspect of the standard cosmological model..."
"In raising this possibility, Neves challenges the idea that time had a beginning and reintroduces the possibility that the current expansion was preceded by contraction. “I believe the Big Bang never happened,” the physician said"
“Who knows, there may be remains of black holes in the ongoing expansion that date from the prior contraction phase and passed intact through the bottleneck of the bounce,” he said.
Denyse commented very well:

Nobody knows "jack sh*t" about the Reality prior to the Big Bang. One may speculate all day long, but until they come up with a theory that makes specific, distinguished, and falsifiable predictions, it's all noise. Then start testing. And testing. And again. Then ring the bell.mike1962

Ok, so tell me why there were universes before the Big Bang?OldArmy94
