The written word of Hawking it is then....Quote from jem:
1. its stu against the written word of hawking.
"The universe can and will create itself from nothing"
"Spontaneous creation is the reason there is something rather than nothing, why the universe exists, why we exist."
"It is not necessary to invoke God to light the blue touch paper and set the universe going."
Quote from jem:
Hawking says this in the end of the paper quote...
"In a cosmology based on eternal inflation there is only one universe with a fractal structure at late times, whereas in top down cosmology one envisions a set of alternative universes, which are more likely to be homogeneous, but with different values for various effective coupling constants."
So what do you imagine Stephen Hawking means by .."one envisions a set of alternative universes"..?
Youâre the dictionary dictator, so you should practice what you preach and accept without question the dictionary meaning of the word universe which is - everything that exists everywhere.
So ask yourself in that case, what is it Hawking is getting at by including the word envisioned here? A multiple -everything that exists everywhere- can't be right. Could you possibly bring yourself to consider you're missing something ?
No of course not, you'd never be able to do that.
Hawking, like God, only means what you want him to.
"A central idea that underlies the top down approach is the interplay between the fundamental laws of nature and the operation of chance in a quantum universe. In top down cosmology, the structure and complexity of alternative universes in the landscape is predictable from first principles to some extent, but also determined by the outcome of quantum accidents over the course of their histories."
... so these "alternative universes" in string theory are the quantum state of all alternative histories for the universe.
Oh and donât forget the written word of Hawking. The top down proposal says the universe is â¦
"the interplay between the fundamental laws of nature and the operation of chance in a quantum universe."
Lol.Quote from jem:
2. Stu you got the entire point of the paper incorrect. Hawkings paper is multiverse coupled with a top down approach.
http://arxiv.org/PS_cache/hep-th/pdf/0602/0602091v2.pdf
".... In fact if one does adopt a bottom-up approach to cosmology, one is immediately
led to an essentially classical framework, in which one loses all ability to explain cosmologyâs central question - why our universe is the way it is. In particular a bottom-up approach to cosmology either requires one to postulate an initial state of the universe that is carefully fine-tuned [10] - as if prescribed by an outside agency or it requires one to invoke the notion of eternal inflation [11], which prevents one from predicting what a typical observer would see.
What multiverse.
So?Quote from jem:
3. Here we put forward a different approach to cosmology in the string landscape,
based not on the classical idea of a single history for the universe but on the quantum
sum over histories [12]. We argue that the quantum origin of the universe naturally
leads to a framework for cosmology where amplitudes for alternative histories of the
universe are computed with boundary conditions at late times only. We thus envision
a set of alternative universes in the landscape, with amplitudes given by the no
boundary path integral [13].
Like I said earlier, string theory is not sufficiently falsifiable. Hawking is proposing the top down approach is a better way to take it further.
No divine creator in this anywhere. Pathetic how you're always trying to stuff one in.
