Genesis - Big Bang mash-up

Sarcasm alert!!

Start a thread on the noboundry concept of the universe and Theoretical Physics and Cosmology, Quantum Mechanics and we will deal with it.

Actually on second thought read the references that began this thread if you understand them,

this is a good thread. I may post osme references on concepts like the no boundary and the time issues.
I am familiar with the 'something from nothing' bb theories, but they are a theoretical conceptualization of an impossible event.

I dont see why given that the "nothing" referred to in the theories seems to be more of a technical term meaning nothing but the fabric of space-time and not the strawman absolute nothing you appear to be implying in my view.

Ok, if the fabric of space-time of the universe pre-exists the bb in the bb theory, then so long as the mass of the universe stays the same pre and after bb, I'm ok with it as a theory. But getting mass from no mass is impossible.

It is unknown if there was a "pre-big bang" according to my understanding, scientists only have a limited knowledge of what happened at T>0, so it is not possible to compare the mass after the big bang to an unknown quantity.
But getting mass from no mass is impossible.
Well the mass may have always been there or it may have come from something different to mass, as far as I'm aware it is unknown.

But if there was no pre-bb, then that implies absolute nothing! Mass from no mass, existence from no existence, something from nothing is not solid science imho.

I guess that pretty much settles it,

although I suspect that your "familiar with" suggests more familiarity than is warranted.​

And when Santa looks north from his North Pole abode he is truly staring into the void.

To what should we credit your expertise regarding "solid science"?

There are many hypothesis on pre bb, here is one considering a universe from nothing. And it is solid science, backed ip with solid maths.

[1404.1207] Spontaneous creation of the universe from nothing
But where did the pre-bb vacuum bubble that was created by quantum fluctuations of the metastable false vacuum that expand exponentially no matter whether the bubble is closed, flat or open, and ends when the bubble becomes large come from?

Quantum fluctuations as it says in the part you quoted.

If you take this view based on your intentional ignorance of science and Quantum Mechanics,

The "nothing" in a allegorical description of the Quantum World based on Quantum Mechanics is NOT truly "absolute nothing."

Ok, I have no trouble accepting cosmic transmutations involving one state into another state, but mass from no mass is impossible. Do you agree?

No it implies a Quantum world of Quantum fluctuations that form singularities like black holes and likely the merging of Black Holes,
Mass from no mass, existence from no existence, something from nothing is not solid science imho.
The mass of our universe did not come from nothing. It came from the expansion of the energy of the singularity of the initial universe, The equivalence of energy and matter described by Einstein. Hydrogen formed first.

So quantum fluctuations of the false vacuum pre-exist bb? Well that is not something from nothing.


Read (and understand) the paper, not just the preamble. The quanta in the vacuum bubble appear from nothing. Yes i know its a difficult concept to get your head around but ignorance of quantum mechanics does not make it go away.
