Cassius lol it's connected 😂. I finally watched that Krauss/Dawkins video last night, and it was excellent! It was clear that Dawkins was very excited about Krauss' "something from nothing" and was saying that it is a huge blow to religions, by demonstrating that something from nothing doesn't require a god. I agree with him. Although the "nothing" had gravitational fields, it had no matter but was unstable and then "something " appeared. It really is amazing that stuff, matter, could come into existence.
It's definitely an example of how language, an abstraction, can't substitute for the reality it describes. But for most people, the phrasing is right. Most people don't consider a gravitational field with no particles to be a "thing". If you stretch the definition to include fields, then obviously the sentence falls apart and there is maybe no such thing as "nothing" anywhere, so it's a moot point.
For most people, and I think for Epicurus based on his reasoning, getting all the "stuff" we see in the universe from a condition with no particles is at least like getting "more something" than you started with, and that's a violation of nothing comes from nothing. Because of that, something from nothing is closer to "more something from less something", and it's probably as good a description as can be made without coining new words.
Epicurus' model really did not have elementary particles that could come from something else or change into each other. That is a big difference. They could come together to make different things but not one alphabet letter turn into another or a letter come from the page.
I am with Dawkins on the god as barnacle!😂
Anyway, Dawkins wasn't disagreeing with Krauss. If you mean the part where Krauss uses the analogy of biology from chemistry as something from nothing... it's again a difficulty of language, but Krauss is right in that consciousness remains confusing to the point that some researchers still wonder if it has to be some inherent property of matter that becomes more complex with structural complexity. Is consciousness emergent, a something of a new type, or something else? Nobody knows yet.
You have said you don't like how Krauss acts as if we know this happened for sure, but he never said that! What he said is that it _could_ have happened, and that alone is marvelous. He was very careful not to exceed what was supported by observations. It was beautifully stated.
It was also fun to hear them talk about the possibility that alternative physics could have arisen-- different universal constants, etc. Still minus god. There could have been, or maybe is, a universe where the observations we make about matter/energy are very different! But it still wouldn't need a god.
I thought it was a lovely, friendly, enthusiastic discussion between friends. I'm glad I watched it. These men have the attitude towards science I wish everyone had-- they take delight in it. It's fun, pleasurable. And it consistently renders god a redundant barnacle of a notion. 😂
