SQPR, Sub Quantum Physical Reality, dispenses from the Big Bang alltogether, replacing it by a very long duration, maybe 100 billion years, slow expansion driven by Dark Energy, an emerging property caused by SQPR (this emergence explains the Hubble tension, as the expansion is accelerating).
The present Big Bang reigning model is called the Lambda Cold Dark Matter model. ΛCDM is god-like, yet even more precise than the Bible: it knows everything there is to know about the first three minutes, not just seven days, and all the peaks of temperature in cosmic weather, 14 billion years ago… All this precious precision arises from supposing a lot of things… many of which have never been observed, but hypothesized to make the ΛCDM fit apparent observations.
An example is the Inflaton Field. Nobody has seen an Inflaton. It’s supposed to have accelerated the expansion of the universe just so, many orders of magnitude beyond the speed of light. There is no hope of seeing the Inflaton appear at CERN. The Inflaton inflates all, hence its name. However, there is something else that inflates, namely Dark Energy… Dark Energy showed up as the accelerated distanciation of Type I Supernovae… by a number of teams. The Nobel Prize was awarded, so strong is the experimental evidence for this Dark Energy. Question: why would the universe have two distinct inflation mechanisms, one observed, Dark Energy, and the other, the Inflaton, to please cosmologists and their book publishers, thrilled by the market power of the first minutes of god?
ΛCDM evolved from the Big Bang, which was criticized from its onset. To ridiculize it, physicist George Gamow invented the term “Big Bang”. Little did he know that his mockery would become sacrosanct…
ΛCDM assumes that Dark Matter was there from the beginning, and brought galaxies into existence. So galaxies should start small, and then accrete. We should see that in the distance. However, the six meter space telescope is revealing enormous, well formed spiral monsters, out there in the most distant past…. While more recent galaxies turn out to be smaller… and the latter were expected to be bigger from increasing accretion caused by Dark Matter. it’s the universe upside down!
The El Gordo galactic cluster, a large structure located at seven billion light-years, is more consistent with cosmological simulations in the framework of Modified Newtonian Dynamics MOND due to more rapid structure formation. I do not believe in MOND, because it’s ad hoc, but SQPR, which does not contradict Newtonian Dynamics as grossly as MOND does, is fully compatible with El Gordo… And SQPR was derived to solve problems in Quantum Physics… It’s not ad hoc, like MOND, stated just to depict what gravity acts like… If Dark matter did not exist (but there is evidence it does, see the Bullet Cluster, which looks impossible to explain without Dark Matter).
ΛCDM assumes that Cosmic Background Light does not get tired: all the observed Cosmological Redshift is caused by the expansion of the universe, according to ΛCDM. Interestingly the Cosmological Principle (that the universe looks everywhere the same, from everywhere) seems to be violated by observations, as there is a motion discrepancy, and other visual asymmetries between Cosmic Microwave Background and motions of dstant quasars (inter alia). As a result of the Hubble tension in cosmology, some researchers have called for new physics beyond the ΛCDM model…. But they stay prisoners of the Standard Model of QFT, which predicts neither DM nor DE.
Considering Quantum Entanglement at a cosmological scale, there are good reasons to believe it would break asymmetrically. Assuming Asymmetric Quantum Entanglement Collapse (AQEC), brings forth the SQPR theory, in which there is just one inflation mechanism, light gets a bit tired, Dark Matter, and Dark Energy are both emergent and with a common origin, namely AQEC.
The very precision of the ΛCDM model obtained from a lot of suppositions, makes it brittle. “If anything changes, it’s going to change everything,”as a famous cosmologist put it. It is entirely possible that dead cosmologists confused appearances and reality, by making suppositions about reality, 14 billion years ago, more compatible with the Bible of their childhood… than with what modern telescopes see.
A model can fit to “observations” pretty well, and be completely wrong, as happened with Ptolemaic astronomy. The professionalization of science is no guarantee against that, far from it. Well paid and honored professionals have no interest to rock the boat they are first class passengers of.

P/S:
“The Big Bang never happened” says Eric Lerner, a longtime advocate of an alternative cosmology to the mainstream, known either as a plasma cosmology or the electric universe.

The plasma universe was first proposed by Hannes Alfvén in the mid-1960s. With such high energies, large numbers of charged particles, and dense environments, cosmological electric and magnetic fields could get quite large.
Alfvén wound up developing the field of physics that’s now known as magnetohydrodynamics (MHD), which plays important roles:
- in the environments of stars and stellar remnants,
- in plasmas throughout stellar systems and the interstellar medium,
- around black holes and neutron stars,
- and throughout galaxies, where they help shape large-scale magnetic fields.
For his revolutionary work, Alfvén won the 1970 Nobel Prize, and MHD is now an essential part of a wide variety of astrophysical applications.
Alfvén went a step farther when he proposed his plasma cosmology, asserting that perhaps, on cosmic scales, gravity isn’t all that important, and that instead, electric and magnetic fields and forces were responsible for shaping the Universe. In this model of the Universe, a wide variety of observables with a standard explanation within the Big Bang paradigm would need to be replaced with a wild alternative.
This Alfvén universe must be cyclic, which seem contrary to observations. Such is not the case with MOND and SQPR, which are compatible with an expanding, evolving universe.
