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?
