If this is true it almost literally means black holes are a way for universes to make children. If we apply Darwin’s principles of the strongest survive this must mean that universes that produce the most black holes are the “best”. If correct, what does this actually mean?

Darwinian logic requires a feedback loop. And because those universes are isolated then there’s no “incentive” of a universe to have more “offspring”?

Earlier quoted context omitted.

How so? If you attribute it to an earlier universe, you are just pushing the problem further back. It doesn't seem to be a proof or even a mild indication.

The universe casually didn't follow the laws of physics immediately after the Big Bang, an improbable event directly after an improbable event. No explanation has been found, even according to CERN, why everything that was created was not spontaneously annihilated. Attributing that to a divine intervention is the most probable explanation. CERN attributing this to "Some unknown entity" is humorous. One theory (which…

Incorrect.

First, let's be clear, "our understanding of the laws of physics" is not "the actual laws of physics". Every physicist knows this. The universe always follows the real laws, physicists are very excited about the difference because it's a chance to win a Nobel Prize.

For example, the one in 1980 for the discovery (in 1964, they're slow to award the prize) of CP violation in decays of neutral kaons, which is fancy physics language for "matter and antimatter do not behave the same way". This year, the LHCb experiment in CERN also discovered CP violation in baryons.

In fact, this is in your own linked article from CERN: """In the past few decades, particle-physics experiments have shown that the laws of nature do not apply equally to matter and antimatter. Physicists are keen to discover the reasons why."""

That said, personally I like the response from Sabine Hossenfelder: There's nothing to be explained, conservation laws only apply to time-evolution of a system, not to the initial conditions.

We don't look for a reason why the mass-energy was non-zero, why do we even need one for why the baryon number isn't zero?

Might as well believe in God if you’re going to believe in spontaneous accidental creation…

Belief in anything is completely trivial unless you act based on those beliefs. No one is going to waste time worshiping, or murder someone over, the "nothing" from before "something".

What is the currently accepted theory?

We have no theories working at those conditions. Wiki says

> General relativity also predicts that the initial state of the universe, at the beginning of the Big Bang, was a singularity of infinite density and temperature.[6][obsolete source] However, classical gravitational theories are not expected to be accurate under these conditions, and a quantum description is likely needed[7].

At t=0 or "before" none

I speculate that the big bang is/was fueled by all the black holes that existed and will exist, like a huge cycle where all the energy sucked into black holes converges at the same point in time causing the big bang.

How do you deal with Hawking radiation?

Maybe with space expansion? With more space, particles interaction is weaker overall. So the whole system kind of loses total energy.

The word "research" in this title is a handy placeholder for indeterminate conjecture. No research happened, it's a theory he made up.

I would argue that theory is a critical part of the research process and is therefore research.

There’s of course a line between simply coming up with ideas that are quickly provably wrong or inconsistent vs generating ideas that are consistent and not quickly falsified. It’s especially valuable the ideas are falsifiable and it seems like this is the case here.

As such, theory finds patterns in existing knowns, makes some leaps and tries to connect them. Then empirical evidence can help solidify or falsify those ideas. But we tend not to just connect dots of empirical data without attempting to know the casual relationship, otherwise the connections can be rather nonsensical or may have weak predictive power.

With all that said I didn’t read the paper in detail nor am I qualified in this domain to say if it’s quackery or a reasonable shot a developing some new theory. It is peer reviewed and published in APS so I suspect it’s not complete quackery: https://journals.aps.org/prd/abstract/10.1103/PhysRevD.111.1...

I'm not a scientist or astrophysicist but i do believe in science, is it ok to believe that we as humans and all our scientific development still very very far from proving anything remotely close to how the universe got created? I feel this subject is for humanity in year 2600 to start discussing it.

Scientist still can show their theories and search papers and i can't understand a shit but i don't believe in any theory that proves how the universe got created.
