I have read for a couple weeks now about a universe from nothing. I understand that the gluon field supports quarks in a proton. I understand that the universe has zero total energy. I'm confused about the beginning of the universe, and terminology.

When Dr. Lawrence Krauss debated Hamza Tzortzis, Krauss told Tzortzis that "nothing" meant "NOTHING! Zip, zero, nada!" There was no universe, no quantum, and no foam. OK, nothing means no universe. No space, time, or laws. The universe was created when nothing was there before, or it wasn't there before. Then, the Lambda CDM theory asserts a quantum foam, substrate, or some such, prior to the big bang.

Q: Is Dr. Krauss referring to a different model than the Lambda CDM?

A:

  • $\begingroup$ No... laws. I’m skeptical that Dr. Krauss thinks that. (I did not downvote.) $\endgroup$ – G. Smith Sep 26 '20 at 20:20
  • $\begingroup$ @G.Smith No laws because there is nothing for them to apply to. There's an earliest time and anything before that is "north of the north pole". $\endgroup$ – benrg Sep 27 '20 at 0:08
  • $\begingroup$ I understand that the gluon field supports quarks in a proton. What do gluons have to do with the universe-from-nothing idea? $\endgroup$ – G. Smith Sep 27 '20 at 1:46
  • $\begingroup$ @G.Smith youtube.com/watch?v=8Zp32xPzbw0 Why I brought up the gluon field: I've been watching videos that talk about empty space at the macro and micro level, but even at the macro level, there are quantum fluctuations, so we are back to the micro. I heard you can destroy a quark from empty space. So, my confusion stems from a lack of the explanation I seek. Since I was confused, A better question might be, what kind of scalar field could be created by a fluctuation resulting in a mass that weighs 1/100,000 of a gram? $\endgroup$ – Ari Sep 27 '20 at 22:53
