The fact of the matter is that we don't know where the universe we see around us came from. The earliest time our observations can tell us about was 13.8 billion years ago, when it was so hot and dense that we can't say what, if anything, happened prior to that. When scientists say the universe was created 13.8 billion years ago, they mean the universe as we know it.Until the 60's or 80's science believed the universe always existed. Ooops. NOW they don't and science says it came into being but they don't know how.
Would you say this is SOMETHING from NOTHING?
I THINK SO....
There is a wide variety of models for how our universe may have arisen and/or what happened prior to the earliest time we can infer from observation.
If you read his book, you'll see that he uses the word 'nothing' in a number of ways - and takes great pains to explain exactly what he means by it in each case, to forestall just that kind of misleading implication.I see Lawrence Krauss trying to prove now that SOMETHING can come from NOTHING....
What more needs to be said?
Just as we commonly say, "there's nothing in the cupboard" when the cupboard is empty except for air, he makes the point that 'empty' spacetime, i.e. spacetime with no particles or forces (the void), is often called 'nothing', but is a source of continual oscillations of quantum fields, and has the potential to phase-change to a different state, producing a new kind of spacetime, a new expanding universe. Likewise, it seems likely that spacetime itself is emergent from an 'emptier' state, another kind of 'nothing', which has the potential to spontaneously generate spacetime universes.
You can argue with the physics or the mathematics underlying it, and you can disagree with his interpretations, but misrepresenting him is ignorant.
