Actually, the Bir Bang does not postulate that ‘all matter’ was concentrated in a singularity. Here again you err, along with conflation of ‘creating’ and ‘forming’, as TxnMa has cogently pointed out. The singularity may have been without temperature, without mass even. It was CREATED by the Creator. What we may conjecture is that the CREATED singularity differentiated into ‘some thing’, formed into something, and that what followed, by God’s direction/information injected into the formless void, was the manifestation of what would eventually form quarks and every other form of matter. It is like saying you can create life in a test tube, but you will need a little RNA to get started, if you get my drift.
Silly me! Guess that's what passes for public school science. To be sure, I read the NASA website, and took the following statement
"...when the entire Universe was contained in a single point in space."
to mean all matter as well. Thanks for clarifying my simplistic reading! You advise NASA to clarify their misleading statements.
You may also want to correct Stephen Hawking as well, who stated
At this time, the Big Bang, all the matter in the universe, would have been on top of itself. The density would have been infinite. It would have been what is called, a singularity.
You're not half as clever as you think!
