Asked at ZME Science:

This very homogeneous image of the early universe is proof of two things we discussed. First, that the ‘bang’ was not triggered by something, and second, if there is no point of origin for an explosion, there is no center of the universe, no privileged spot.

There is another important characteristic of the universe, it does not indicate any relevant direction. In fancy words, the universe is isotropic in the big picture, meaning it doesn’t have a preferred direction. Roads are not isotropic, you have to be going in a direction, a sink is not isotropic, the water moves to the drain. – Paula Ferreira* (March 8, 2023)

How do we know that the Big Bang was not “triggered by something”? Do we know anything about what went on before that?

*Ferreira is a PhD student in physics.

Within the framework of general relativity, it is logically impossible for the “Big Bang” to have “triggered” by anything.
I take it "triggered" means "caused." So, this means that it is (somehow) "logically impossible" that our universe has a cause. Does this mean that the existence of our universe is necessarily unrelated to any proposed multiverse? IOW is it "logically impossible" for a proposed multiverse to have any causal relationship with our universe?Origenes

Within the framework of general relativity, it is logically impossible for the "Big Bang" to have "triggered" by anything. This is because what we call "the Big Bang" is a badly chosen term for a mathematical truth -- more precisely, a mathematical truth within the framework of general relativity. As I understand GR, the universe is a four-dimensional object. As one approaches the "edges" of this object, the value for the curvature of space-time approaches infinity. The so-called "singularity" is the name for the parameter that is asymptotically approached by the value of the curvature of space-time. Since we can only asymptotically approach the singularity, the question "what caused the Big Bang?" is meaningless -- as long as one is working within the basic assumptions of general relativity. Hence, until such time as general relativity is replaced by a successor theory, the question "what caused the Big Bang?" has no meaningful scientific answer. If one wishes to insist that it's a meaningful question, by all means -- as long as we're clear that it is at that point that one has crossed over the border between science and metaphysics.PyrrhoManiac1

We are left with two choices: the center can be anywhere we wish, even the center of the earth, or the center of the earth. Hmmmmm.buffalo

From the article,
"Our current understanding of the universe is guided by the Big Bang Theory.,,, Our universe went through different ‘moods’. First, a sudden accelerated expansion (called inflation).,,, The CMB is the relic that we can observe today to understand the structure of the universe. The Planck Satellite mission observed, with high precision, those CMB photons and concluded the universe is nearly the same on large scales.,,, No privileged place This very homogeneous image of the early universe is proof of two things we discussed. First, that the ‘bang’ was not triggered by something, and second, if there is no point of origin for an explosion, there is no center of the universe, no privileged spot."
Funny, a spokesman for Planck from the European Space Agency had a VERY different take on what Planck has revealed,
New Planck Findings Challenge the Big Bang Theory - (Disconfirms inflationary models) – video Quote at 2:00 minute mark: "What's surprising in Planck's latest findings and is inconsistent with prevailing theories, is the presence of unexpected large scale anomalies in the sky. Including a large cold region. Stronger fluctuations in one half of the sky than the other. And less light signals than expected across the entire sky." Planck spokesman: "When we look at only the large features on this (CMBR) map you find that our best fitting theory (inflation) has a problem fitting the data." "Planck launched in 2009,, is the 3rd mission to study the Cosmic Microwave Background to date. While these unusual features in the sky were hinted at the two previous US missions, COBE and WMAP, Planck's ability to measure the tiniest of fluctuations in the Cosmic Microwave Background has made these so called anomalies impossible to ignore." Planck spokesman: "Because of these features that we are finding in the sky, people really are in a situation now where they cannot ignore them any more. ,,, We've established them (the anomalies) as fact!". https://www.youtube.com/watch?v=M2CWaLU6eMI
In fact, these 'anomalies' in the CMB have done more than just cause problems for inflation theory, these anomalies have, directly contrary to what Ferreira claimed her article, revealed a "privileged spot" in the universe.
"The Cosmic Microwave Background (CMB) Radiation contains small temperature fluctuations. When these temperature fluctuations are analyzed using image processing techniques (specifically spherical harmonics), they indicate a special direction in space, or, in a sense, an axis through the universe. This axis is correlated back to us, and causes many difficulties for the current big bang and standard cosmology theories. What has been discovered is shocking. Two scientists, Kate Land and João Magueijo, in a paper in 2005 describing the axis, dubbed it the “Axis of Evil” because of the damage it does to current theories, and (tongue in cheek) as a response to George Bush’ Axis of Evil speech regarding Iraq, Iran and, North Korea.,,, The “Axis of Evil” correlates to the earth’s ecliptic and equinoxes, and this represents a very unusual and unexpected special direction in space, a direct challenge to the Copernican Principle. - Robert Sungenis - What Is Evil About The Axis Of Evil? - February 17, 2015
Here is an excellent clip from "The Principle" that explains these ‘anomalies’ in the CMB in an easy to understand manner.

Also of note, the cosmological principle, (which is a main assumption behind the standard model of cosmology), is now being brought into question,
“Two years ago I told you about a new quasar measurement that came out completely wrong. A stunning 4.9 sigma away from the prediction. What they did in this work was to calculate the motion of our galaxy relative to all the other matter in the universe, and relative to the radiation from the cosmic microwave background. According to the currently accepted standard model of cosmology the two results should agree. They do not. “This analysis has now independently been repeated by a second group, which just reported their results on the pre-print server. The paper has not yet been peer-reviewed, but they confirm the anomaly and indeed they find an even higher statistical significance of 5.7 sigma. “I really think that cosmologist should pay more attention to this anomaly, … – Sabine Hossenfelder – – New Cosmology Anomaly Confirmed, Particle Physics Anomaly Vanishes (2:24 minute mark – January 11, 2023) https://uncommondescent.com/intelligent-design/sabine-hossenfelder-on-an-anomaly-that-no-one-seems-to-be-investigating/#comment-773797 A Test of the Cosmological Principle with Quasars (2021) and Testing the Cosmological Principle with CatWISE Quasars: A Bayesian Analysis of the Number-Count Dipole (December 2022) Our model of the universe has been falsified The cosmological standard model is wrong - Feb. 14, 2023 Excerpt: "The standard cosmological model also assumes the cosmological principle, according to which the universe looks the same in every direction. Using these assumptions, scientists can calculate how the initial smoothness of the cosmic microwave background evolved into an increasingly clumpy and moving distribution of matter, made of filaments, galaxy clusters and galaxies. The measurement of this process allows astronomers to test if the model is correct.,,, What we do we know about the smoothness, or the lack thereof, of the matter distribution in the universe, from more direct measurements, is that it’s much clumpier and faster-moving in parts than the standard cosmological model allows. In fact, the observations tell us that the Universe is structured on every scale, amounting to a falsification of the standard model of cosmology with extreme (more than 5 sigma) statistical confidence. A serious physicist would never again touch a theory that has been ruled out at such a significance level. (Concluding sentence),, Thus, rather than discarding the standard cosmological model, our scientific establishment is digging itself ever deeper into the speculative fantasy realm, losing sight of and also grasp of reality in what appears to be a maelstrom of insanity. https://iai.tv/articles/our-model-of-the-universe-has-been-falsified-auid-2393?_auid=2020
It is important to note that the cosmological principle, (which is a main assumption being challenged by these anomalies), derives from the Copernican Principle. (And the Copernican principle has been one of the main arguments used by atheists to try to argue that earth, and man, are not to be considered 'privileged' in this universe)
Copernican principle Excerpt: The standard model of cosmology, the Lambda-CDM model, assumes the Copernican principle and the more general cosmological principle. https://en.wikipedia.org/wiki/Copernican_principle#Physics_without_the_principle
Here another recent finding which also implies “an apparent breakdown of the Copernican principle or its more generalization, cosmological principle, upon which all modern cosmological theories are based upon.”,,,
Is there a violation of the Copernican principle in radio sky? – Ashok K. Singal – May 17, 2013 Abstract: Cosmic Microwave Background Radiation (CMB) observations from the WMAP satellite have shown some unexpected anisotropies (directionally dependent observations), which surprisingly seem to be aligned with the ecliptic\cite {20,16,15}. The latest data from the Planck satellite have confirmed the presence of these anisotropies\cite {17}. Here we report even larger anisotropies in the sky distributions of powerful extended quasars and some other sub-classes of radio galaxies in the 3CRR catalogue, one of the oldest and most intensively studies sample of strong radio sources\cite{21,22,3}. The anisotropies lie about a plane passing through the two equinoxes and the north celestial pole (NCP). We can rule out at a 99.995% confidence level the hypothesis that these asymmetries are merely due to statistical fluctuations. Further, even the distribution of observed radio sizes of quasars and radio galaxies show large systematic differences between these two sky regions. The redshift distribution appear to be very similar in both regions of sky for all sources, which rules out any local effects to be the cause of these anomalies. Two pertinent questions then arise. First, why should there be such large anisotropies present in the sky distribution of some of the most distant discrete sources implying inhomogeneities in the universe at very large scales (covering a fraction of the universe)? What is intriguing even further is why such anisotropies should lie about a great circle decided purely by the orientation of earth’s rotation axis and/or the axis of its revolution around the sun? It looks as if these axes have a preferential placement in the larger scheme of things, implying an apparent breakdown of the Copernican principle or its more generalization, cosmological principle, upon which all modern cosmological theories are based upon. A large anisotropy in the sky distribution of 3CRR quasars and other radio galaxies http://arxiv.org/pdf/1305.4134.pdf
And it is the large scale structures of the universe, on top of the CMB anomalies, which drive the final nail in the coffin for the belief that the earth does not have a ‘privileged’ position in the universe. As the following article explains,
Debunking Palm and MacAndrew on the CMB Evidence”, p. 8 Excerpt: “Of course to have an exact position, (or what we would call an ‘exact center’ in the universe), we would need an X axis, a Y axis, and a Z axis, since that will give us three dimensions in Euclidean space. The CMB dipole and quadrupole gives us the X axis and Y axis but not a Z axis. Hence, the X and Y axis of the CMB provide a direction, but only an approximate position. That is why we have continually said that the CMB puts Earth “at or near the center of the universe.” For the Z-axis we depend on other information, such as quasars and galaxy alignment that the CMB cannot provide. For example, it has been discovered that the anisotropies of extended quasars and radio galaxies are aligned with the Earth’s equator and the North celestial pole (NCP)4.,,, Ashok K. Singal describes his shocking discovery in those terms: “What is intriguing even further is why such anisotropies should lie about a great circle decided purely by the orientation of earth’s rotation axis and/or the axis of its revolution around the sun? It looks as if these axes have a preferential placement in the larger scheme of things, implying an apparent breakdown of the Copernican principle or its more generalization, cosmological principle, upon which all modern cosmological theories are based upon.” – Ashok K. Singal4 “Is there a violation of the Copernican principle in radio sky,” Ashok K. Singal, Astronomy and Astrophysics Division, Navrangpura, Ahmedabad, India, May 17, 2103,.. Signal states: “We can rule out at a 99.995% confidence level the hypothesis that these asymmetries are merely due to statistical fluctuations.” – R. Sungenis – (“Debunking Palm and MacAndrew on the CMB Evidence”, p. 8). – article http://debunkingalecmacandrew.blogspot.com/2014/10/debunking-palm-and-macandrew-on-cmb_22.html
Thus, far from the small temperature variations in the CMBR being a product of random quantum fluctuations, (as they falsely presupposed with their inflation model), the small temperature variations in the CMBR combine with the ‘largest scale structures of the observable universe’ to reveal teleology, (i.e. a goal directed purpose, a plan, a reason), that specifically included the earth and solar system from the very start of the creation of the universe itself.,,, The earth and solar system, (from what our best science can now tell us), is not just the result of some random quantum fluctuation as atheists had erroneously presupposed with their ad hoc inflation model, (a model which, by the way, was ‘invented’ solely to ‘explain away’ the fine-tuning of the flatness of the universe and the homogeneity of the CMB).
Isaiah 45:18-19 For thus says the Lord, who created the heavens, who is God, who formed the earth and made it, who established it, who did not create it in vain, who formed it to be inhabited: “I am the Lord, and there is no other. I have not spoken in secret, in a dark place of the earth; I did not say to the seed of Jacob, ‘seek me in vain’; I, the Lord speak righteousness, I declare things that are right.”
Of supplemental note, Moreover, it is not just these findings from cosmology that are signaling “an apparent breakdown of the Copernican principle or its more generalization, cosmological principle", there are multiple lines of scientific evidence that converge to overturn the Copernican principle.
Dec. 2022 - In fact, when other lines of scientific evidence are brought forth on top of this evidence from General relativity, such as what Michael Denton has brought forth, and such as evidence from quantum mechanics, CMBR anomalies, life existing at the ‘geometric mean’,, etc, etc.. then we do indeed find that the Copernican principle, (and/of the Principle of Mediocrity) has been thoroughly and impressively, overturned. https://uncommondescent.com/intelligent-design/michael-denton-the-miracle-of-man/#comment-772161
As much as it may hurt an atheist’s feelings to know this, and as far as our best science can now tell us, we are not merely to be considered “chemical scum” as Stephen Hawking, via the erroneous assumption of the Copernican Principle, tried to imply that we were.
“The human race is just a chemical scum on a moderate-sized planet, orbiting around a very average star in the outer suburb of one among a hundred billion galaxies. We are so insignificant that I can’t believe the whole universe exists for our benefit.,,,” – Stephen Hawking – 1995 TV show, Reality on the Rocks: Beyond Our Ken,
Hopefully atheists will soon get over the ‘sad’ fact that they are not to be considered merely ‘chemical scum’ in short order.
Romans 8:20-22 - Common English Bible Creation was subjected to frustration, not by its own choice—it was the choice of the one who subjected it—but in the hope that the creation itself will be set free from slavery to decay and brought into the glorious freedom of God’s children. We know that the whole creation is groaning together and suffering labor pains up until now.

The concept of inflation/expansion of the universe as well as Einstein's general theory of relativity (specifically, spacetime distortion near massive objects) would indicate that ALL points in the universe are indeed the "center" of the universe. The idea that there was no cause for the universe . . . (a) breaks causality, without which everything is magical, and (b) that the universe (which includes space-time, mass-energy, etc.) was caused by space-time inflation is wildly illogical, equivalent to a snake regurgitating itself into existence (eww) as a sort of Ouroboros in reverse. (c) That the universe popped into being by a probabilistic quantum fluctuation doesn't make sense since probability doesn't exist without the passage of time. -QQuerius
