Nobody assumes the 'laws of physics' were the same before the universe began, because they did not even form until shortly after the universe begun. They were a result in the random breaking of symmetry, and the constants and laws of physics are a random outcome of this early symmetry breaking. It's all in the paper. Once again I must suggest that the people responding in this thread actually read the thread that this thread is centered around.
Let me point out the assumptions I think happen in the paper and you tell me.
According to the natural scenario, by means of a random quantum fluctuation
[Quantum fluctuation before the current time and space existed? What is fluctuating and how?] the universe tunneled from pure vacuum ("nothing") to what is called a false vacuum
[Do we know/Can we ever know that the initial state was a state of "nothing"?], a region of space
[I was under the impression that the BB is responsible for the origin of space and time as we know it what kind of space are we talking about here?] that contains no matter or radiation but is not quite nothing. The space inside this bubble of
false vacuum was curved, or warped.
Underlinded text is added by me. Italic parts are edited after being corrected by Jet.
On the laws of conservation yes the paper has a good point, I have also read good papers on the anthropic principles and, trust me, I knew about the model this paper talks about.
However I was under the impression that our scientific "eyes" could not see beyond plank time.
That is what I am talking about. In order to have a fluctuation you need to have something to fluctuate, you do not and cannot know what was there "before the BB" (Even
this phrase is silly in the BB model) and how it behaved.
I read through the paper I have yet to see where it justifies its assumptions that is why I am asking.
