I am not sure where to find people who may understand the following paper but I figured someone here might be interested and or educated enough to weigh in on this subject.
I tried with my local astronomical society and haven't heard anything back from them.
This idea is interesting to me but I don't have the background in mathematics to verify these two people's work that is the focus of the article.
Anyways I thought I'd drop it here as it doesn't look like it has been mentioned and might get bounced around and reviewed or even debunked or confirmed.
Looking forward to dropping jaws, eyes the size of saucers, and wringing of the hands too.
maybe some hair pulling...

No Big Bang? Quantum equation predicts universe has no beginning

The universe may have existed forever, according to a new model that applies quantum correction terms to complement Einstein's theory of general relativity. The model may also account for dark matter and dark energy, resolving multiple problems at once.

here is a link to the actual paper ( it's 4 pages long )

We already have a thread on this here: https://www.physicsforums.com/threads/quantum-equations-suggest-the-big-bang-never-happened.797073/

Not going to happen. :wink:
From the thread linked above:

...there's no reason to take this seriously.

It's standard knowledge within cosmology that the big bang singularity is impossible. The question remains as to what was going on in the densest times. There are two general approaches that theorists have taken in an attempt to explain the discrepancy:
1. Come up with an alternative model which, when extrapolated forward in time, gives a universe that looks like our own. Cosmic Inflation is one example of following this paradigm.
2. Take the currently-known components of our universe and extrapolate backward in time towards the singularity, but make use of a theory of quantum gravity to describe the universe at very early times. Loop Quantum Cosmology is one example here. This is also the approach taken by Ali and Das.

Since there's already a thread on this I'm going to lock this one.

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
