New Theories / Big Bang Theory - How the BBT really works?
« on: 07/11/2020 04:39:13 »
Let's start with the following simple question:
What is the size of the Universe? Is it finite or Infinite?
In the following explanation from NASA, it is stated that the Universe is an "infinite universe expanding into itself?
https://www.jwst.nasa.gov/content/features/bigBangQandA.html
"The Big Bang is a really misleading name for the expanding universe that we see. We see an infinite universe expanding into itself."
How could it be?
I do recall that just few years ago our scientists have claimed that it is finite.
They even told us that the maximal size of our Universe might be 92 BLY (which is called - Observable Universe).
Few weeks ago I had been told that it is finite but unbounded which means a finite Universe without End.
Now it becomes Infinite Universe expanding into itself.
Dr. John Mather, Nobel Laureate and James Webb Space Telescope Senior Project Scientist had also stated:
"The Big Bang happened everywhere at once and was a process happening in time, not a point in time."
However, in the following article it is stated that the Big bang started at singularity:
https://www.big-bang-theory.com/
"According to the standard theory, our universe sprang into existence as "singularity" around 13.7 billion years ago."
Our universe is thought to have begun as an infinitesimally small, infinitely hot, infinitely dense, something - a singularity."
So, please:
What is the real size of our current Universe? Is it finite or Infinite?
If it is finite - Can you specify the real size?
If it is infinite – then how an infinite Universe could expand into itself?
How the Big Bang happened everywhere while it took place at singularity point According to the standard theory?
If it is infinite today, then how it could be at singularity 13.8 BY ago?
That issue of size is critical for the CMBR which had been set during the Era Of Recombination
https://www.jwst.nasa.gov/content/science/firstLight.html
"This process of particles pairing up is called "Recombination" and it occurred approximately 240,000 to 300,000 years after the Big Bang. The Universe went from being opaque to transparent at this point. Light had formerly been stopped from traveling freely because it would frequently scatter off the free electrons. Now that the free electrons were bound to protons, light was no longer being impeded. "The era of recombination" is the earliest point in our cosmic history to which we can look back with any form of light. This is what we see as the Cosmic Microwave Background today"
If the Big Bang took place everywhere, then during the Era of recombination the Universe was already everywhere.
If it was already everywhere then how the expansion could reduce the CMBR temp while it was already everywhere as it was "infinite universe expanding into itself"
Don't you agree that if the Universe is infinite today - it must be infinite at the Big bang moment?
If it is expanding into itself - how that process could reduce the CMBR temp?
Sorry – If our scientists don't know even the basic understanding about the real size of our Universe, (finite or infinite), then how do they know for sure that the whole BBT is correct?
