Einstein tried to explain to the world about Relativity.
Many do not understand what Relativity means.
What is time dilation?
What is Space malleable?

What is passage through a nexus?

Passage through nexus? This is a model. It is no better or worse than infinite density and temperature exploding out of nothing.

Well, I happen to think that it is better. Of course, it could only be at an atomic (or below) level. No star ships slipping through undetected. Densities and temperatures quite high. After all, stars form when matter gets compressed.

By whatever mechanism (and anything is better than exploding out of nothing at infinite density) the dying phase was probably compressed by gravity. Don't forget, this is only a model. At a certain point, the pressure becomes sufficient and the contents (the dying phase of the Universe) 'squirts' through the nexus to be 'born again' as the new phase of the Universe.

"i still try to imagine how that would happen."

I could never imagine anything so . . . . . . (I am lost for words) . . . . . . as an infinitely small Universe at infinitely high density (and all the other infinity stuff) suddenly appearing out of nothing and exploding for no apparent reason.

Same.

To be honest, I agree with the BBT in almost every axiom of it, except singularity. How about replacing it with planck star?

In loop quantum gravity theory, a Planck star is a hypothetical astronomical object, theorized as a compact, exotic star, that exists within a black hole's event horizon, that is created when the energy density of a collapsing star reaches the Planck energy density.
Planck star - Wikipedia

Hi IG, I would think that 'my' nexus must be conceptually similar to a black hole, at least in some respects (minus singularity).

"Under these conditions, assuming gravity and spacetime are quantized, there arises a repulsive 'force' derived from Heisenberg's uncertainty principle. The accumulation of mass-energy inside the Planck star cannot collapse beyond this limit" My emphasis - I like it! Ergo nexus. But it is still hypothetical.

The following paper is worth understanding what is out there.
You can also search arXiv for Super Clusters of Galaxies, giving you an idea of the size of objects.
Not only the size but the enormous number to be researched.

The eROSITA Final Equatorial-Depth Survey (eFEDS): Catalog of galaxy clusters and groups

Seppi, Q. Thibaud
The eROSITA Final Equatorial-Depth Survey has been carried out during the PV phase of the SRG/eROSITA telescope and completed in November 2019. This survey is designed to provide the first eROSITA-selected sample of galaxy clusters and groups and to test the predictions for the all-sky survey in the context of cosmological studies with clusters. In the 140 deg2 area covered by eFEDS, 542 candidate clusters and groups are detected as extended X-ray sources, down to a flux of ∼10−14erg/s/cm2 in the soft band (0.5-2 keV) within 1'. In this work, we provide the catalog of candidate galaxy clusters and groups in eFEDS. We perform imaging and spectral analysis on the eFEDS clusters with eROSITA X-ray data, and study the properties of the sample. The clusters are distributed in the redshift range [0.01, 1.3], with the median redshift at 0.35. We obtain the ICM temperature measurement with >2σ c.l. for ∼1/5 (102/542) of the sample. The average temperature of these clusters is ∼2 keV. Radial profiles of flux, luminosity, electron density, and gas mass are measured from the precise modeling of the imaging data. The selection function, the purity and completeness of the catalog are examined and discussed in detail. The contamination fraction is ∼1/5 in this sample, dominated by misidentified point sources. The X-ray Luminosity Function of the clusters agrees well with the results obtained from other recent X-ray surveys. We also find 19 supercluster candidates in eFEDS, most of which are located at redshifts between 0.1 and 0.5. The eFEDS cluster and group catalog provides a benchmark proof-of-concept for the eROSITA All-Sky Survey extended source detection and characterization. We confirm the excellent performance of eROSITA for cluster science and expect no significant deviations from our pre-launch expectations for the final All-Sky Survey.

Where am I going with this?
To understand you must research?
When people say the universe is 13.7 Billion years old, they do not know the complexity and depth of the universe.
Deep field images area of a rice seed over 13,2 billion years northern hemisphere
Showed over 5000 galaxies over 14 billion years old
Deep field images 13.2 billion years in the Southern Hemisphere showed the same.

So far no one person has given me evidence of the BBT.

Harry, just check this out and tell us which part you don't believe.

I accept most of it EXCEPT the part very close to t = 0 (for want of a better word) where physics breaks down by trying to divide the real world by infinity. I do not believe in a singularity. I prefer a nexus to a previous 'phase' of the Universe.

An emission of light starts from far away, say fourteen billion light years away. It is not going to travel in a straight line since the curvatures, actually the spirals, of the universe turn light's straight lines along curved paths. Be that as it may, the 2-d frame accumulates 2-d frames from the rear (from infinity, thus imploded as to accumulation (what that might look like I leave to your imagination) since infinity cannot possibly be observed), sides, and front, as mergers, as it travels through the universe It, the accumulated merger of 2-d frames arrives at the Earth observer's telescope as movement closest to Earth being largest, graduating to infinitesimal far away, and no movement at all -- a fixed picture -- farthest from Earth. The observable, sensed, universe with its myopic physics (otherwise known as "relative physics" or "physics of relativity").

But universes, time-verses, from Earth to fourteen billion x 6 trillion miles from Earth are universes, plural, now and not observed or observable from Earth. At fourteen billion x six trillion miles the movement that has been occurring over fourteen billion years at that distance, much less beyond that distance -- to infinity, would be the purest blur if they could be observed from Earth at all. Universes, plural, because locally there, there would not be any greater movement than we observe locally to us. So movement in the universe, as to look, is most likely exactly the opposite to what is observed in the light frames, and otherwise sensed, from Earth. Exactly the opposite to relativity's myopia. The greatest movements over time have occurred exactly where we observe the least movement to have occurred, the distances (to infinity) most distant from Earth. And that translates, relatively speaking ('relativity' to local, foreground, Earth speaking (as if the entire universe were closed up to the Earth)) to pure speed, accelerations, in universe! And, again relative speaking, then observed, then thought, to come from what?!

Then again, as I've alluded to before, the non-local background infinity generates its own material physics toward the local (toward us for one local) that in fact do not exist locally to any of an infinity of locals. The totaled up background non-local toward each of all of an infinity of foreground locals. Analogous to the forest having material influence upon each tree making up the forest (the trees are in the forest. The forest is in each of the trees.) It has its own look. It has its own physicality, its own dimensionality in the multi-dimensionality of the Multiverse.

This non-local background materiality has heat as part of its physical multi-dimensionality (BB / Planck heat). It is horizon constant. A constant of distant horizon -- like the constant of the speed of light -- no traveler traveling the open system (therefore the opening system), the hyperspace hyperplanes (plane to plane, to plane), would ever approach.

Which reminds me of the multi-dimensionality of gravity, almost always seen as being 1-dimensional. It is also a dimensionality of planes within planes, within planes. It isn't solely contractive, it is also expansive, else there would be no surface of the Earth, an expanding expanse when approached from outer-space -- or even from high in the sky of Earth. If our local universe were to be descending, dropping, into a large depth of Abyss, we might not observe it to be contracting (closing up), we might observe it to be expanding (opening up), that very expansiveness a product of gravity.

After 268 posts. I believe it to be established that, even if t'were 'grammatical and complete', then it was south of the south pole to begin with.

I have read all the WIKI notes.
If you wish to prove the BBT, than do so, but Using hear say there say , is not proof.
When you talk about infinity and T=0
What do people mean?

I keep on saying show me the proof.
Wiki is written by people who know very little of the complexity of the universe and the properties of matter.

Images showing matter going through changes in time to explain the BBT are Stone Age explanations. Particularly when the images show a monopole rather than a dipolar.
But! Saying that
We do observe dipolar fields coming out of so called condensates that mimic black hole properties.
M87 is a prime example, along the dipole vortices we do observe formation of stars and clusters of stars.
At the centre of the Virgo Super Cluster there lives a mimic black hole, that’s over 100 billion solar masses and the size of the vortices are so big that our Milky Way can fit in the vortex, what the BBT tries to explain, that is happening kind of now as a cyclic event.

I am perfectly happy with my understanding of cosmology and am quite prepared to discuss it in a sane and straightforward manner with interested parties. However, I am not here to be the subject of demands for information from anyone. If anyone doubts the recognised BBT (as I do in a small part around the so called singularity) then they are at liberty to pursue their own enquiries (as I do). I will not readily turn down any polite requests for what are simply my own opinions on the subject, but I am not going to respond to what I consider to be imperious demands.

With due respect, if i offend, I’m very sorry.
No body demands.
Discussion is always open.
If you want to cook in the kitchen, be prepared sometimes to get burnt.
At the end of the day, you eat what you prepare.

Believe what you can prove.
