Kryptid, no-one can truly explain the Big Bang theory.
I understand the modern theories.
It seems daft.
In Science - never, ever, believe unconditionally in any current theory. Give it no more than guarded acceptance.
You know all this. The Big Bang theory originated because spectroscopic observations seem to indicate that galaxies are presently moving apart from each other.The mathematicians said that must mean, that in the past, the galaxies were closer to each other.The mathematicians then said this proved that the galaxies must have come from a single mathematical point.

Isn't that like saying that when a crowd of people go to a football match, and after the match is over, are observed to be dispersing and getting further apart, that the crowd must have come from a single mathematical point within the football stadium.
During this braking, the universe will now look like the big bang is occurring.
relative reference affect
a reference illusion
reference change
base reference
reference of the naked eye
classic universe reference
The telescope only collects photons that were emitted long ago, but which reach us now. This creates a good view in distance for that time, but a poor view in real time. This makes inferring the universe not based on real time data. It would be like inferring modern humans from ancient fossils. A lot of time is ignored due to lack of data.
wouldn't we infer that humans were skeletons who lived underground.

With cosmology,
The expansing adds what could be modeled as a second time vector,
Objects that existed close to the start of BB, no longer exist,
A very distant planet, say 5 billion light years away, that was viewing the earth, would assume the earth, today, was an infant planet due to the time delay. It could not infer our last 5 billion years and what the present looked like on the earth. Looking for intelligent life on distant planets, outside our solar system, runs into the time delay problems. We see the past and but its present.
What we see today, is the most distant objects, appearing to move the fastest. However, since there is a time delay, the behavior of these most distant objects, are not from the present, but are a snapshot from their most distant past. The most distant past had the fastest objects. As we decrease the observational time delay, by looking at things that are closer and closer, the objects get slower; less red shift. This is consistent with an explosion of sorts. Upon detonation the matter expands quickly like a firework in the sky, then the debris slows with time. Based on signal time delay this is observed.
Let me see if I can simplify this with an easier example.
I now added another time vector
As we have grown tired of telling you, Time is not a vector.
