Your own article rebuts your assertion here.Kenny wrote: ↑Sat Dec 18, 2021 2:02 pmThere is a big difference between expansion vs explosion. If it is going to claim to speak for scientific observations and theory, the least they could do is understand these differences.

The first paragraph of your link acknowledges that scientific community often refers to the Big Bang as an explosion.
"'The Big Bang was an expansion of space, not like an explosion at all, despite what countless books, videos, articles and statements (even by scientists) often depict. Let’s look at the differences between an explosion of something into space versus an expansion of space."
So even your own source acknowledges that the scientific community often describes the Big Bang as an "explosion".
That said I do agree with Wikipedia and your article here that
The Big Bang was not an explosion of something into space
An accurate description of the Big Bang would be...
The Big Bang was an explosion or expansion OF space.
And neither of the National Geographic videos describe the Big Bang as an explosion INTO space.
That is a true statementNo. AT 1min 05sec into the video it says the explosion happened and during that time matter and energy were created.DBowling wrote: ↑Sat Dec 18, 2021 10:50 am You are wrong on the facts here
Matter and energy were created during the Big Bang explosion/expansion. The Planck Epoch makes up the earliest phase of the expansion and does not encompass the full duration of the Big Bang.
The Planck Epoch lasted from time = 0 to 10^(-43) seconds (your assertion that the Planck Epoch occurred tens of thousands of years after the beginning of the explosion/expansion is inaccurate. 10^(-43) seconds is the smallest fraction of a second not tens of thousands of years)
According to the National Geographic video, energy existed during the Planck Epoch, but matter did not exist during the Planck Epoch (which I have no disagreement with).
Again you either misunderstand or misrepresent the sequents of events the video is describing.at 1min 19sec it speaks of 2 major era’s that happened after the explosion was the radiation era where all the epoch’s began to include the Planck Epoch where it claims matter did not exist during this time.
The video clearly states that energy existed during the Planck Epoch.
All the matter and energy of the universe were created during the Big Bang explosion, but at different times during the explosion.
The video explicitly states that energy was present during the earliest phase of the explosion (the Planck Epoch) and that matter was not present during the Planck Epoch.
Uh... do you understand how exponential notation works?“after the Planck Epoch and during the inflammatory Epoch which was hundreds of thousands of years later”,DBowling wrote: ↑Sat Dec 18, 2021 10:50 am As noted above you are factually incorrect regarding the timing of the Planck Epoch
You are also factually incorrect about when the universe grew from the size of an atom to the size of a grapefruit.
According to the video that occurred during the Inflationary Epoch (not the Planck Epoch)
those were my exact words
The Inflationary Epoch occurred a fraction of a second later, not "hundreds of thousands of years later"
I already stated that I disagreed with the size of initial singularity given in the first National Geographic video.So when did it go from a few cm wide (claims of the first video) to the size of an atom (claims of the second video) vs we can’t determine the size of anything because we can only guess concerning the size of the observable Universe which is not the entire Universe (claims of Wikkipedia)? You can’t claim they are all right, because each contradicts each other, so you gotta pick one.
But as I noted earlier
The key here is that the precise size of the singularity (which science doesn't know for sure anyway) has no bearing on whether matter, energy, space and time were created by the Big Bang.
I do agree with the key relevant point about the singularity from the video
"Big Bang began as a hot and infinitely dense point"
