The Big Bang: What really happened at our universe's birth?

[Admin]

Our universe was born 13.7 billion years ago in a massive expansion that blew space up like a giant balloon.

The author might want to correct a nit or two...

"These newly created atoms were all positively charged, as the universe was still too hot to favor the capture of electrons."

["nuclei" not "atoms".]

Also, the updated age for the Universe is now 13.8 billion years.

Another discussion on the topic too but perhaps a bit more disclosed as well.

MSN reported this too, https://www.msn.com/en-us/news/tech...erse-s-birth/ar-AATAdLj?ocid=msedgdhp&pc=U531

"So the very beginning of the universe remains pretty murky. Scientists think they can pick the story up at about 10 to the minus 36 seconds — one trillionth of a trillionth of a trillionth of a second — after the Big Bang. At that point, they believe, the universe underwent an extremely brief and dramatic period of inflation, expanding faster than the speed of light. It doubled in size perhaps 100 times or more, all within the span of a few tiny fractions of a second."

We know from Alan Guth in 2013, that the universe scale at inflation maps 10^-53 m to 1 m size today. It is not hard to figure out the size here using 93 billion light years diameter today. In the range 10^-27 m size and Allen's Astrophysical Quantities, Fourth Edition reports the classical electron radius in the 10^-15 m range. It is amazing to me how cosmology works to explain our origins and how *accurate* all the math must be so today we can know with *heliocentric certainty* that everything we see today, started out in an area smaller than an electron That is quite a creation account
