So now you choose to argue for a multiverse.
Nope. You are trying to assign to me a position that I do not hold. I make absolutely no claim as to the number of expandiverses that exist or that have existed beyond the one in which I find myself. I have thoroughly explained my (humanity's) severe lack of visibility. I do not know and I have no belief in that regard. I don't even have any interest. My only interest is in the properties of the expandiverse in which I find myself.
Light is not concrete nor a boundary.
Yes, it most certainly is. The light as I described it most certainly forms the boundary that I described.
This is assuming there is a 'first light',
Yes, which is why I took the time to explain the concept of a singularity. i.e. roll back time to the theoretical limit.
i.e. a Big Bang. Circular reasoning.
Nope. The idea of a singularity is a rational assumption based on countless observations. No one is requiring you to accept the observations, but you can't very well hold those observations against those who have made them and documented them.
You are making that claim,
I never have.
A gallon is not a measure of the universe.
Sure it is. I can point to one gallon of the universe right now. You can too.
No science is being discussed here.
That's what I've been saying. Nobody has breached any of Hawking's properties. All that has been discussed is the theoretical limit of a singularity, which is nothing more than a definition.
Also, Hawking addressed your idea of an infinitely timeless universe and noted that for it to be the case, the stars that we see would have had to have had an infinite supply of energy, having shown for an infinite amount of time. This is a valid argument that needs a response. If your answer is that God has been feeding the stars with energy for eternity, then there is a problem because science can't build religion into its models (Occam's Razor cuts it out). Without an explanation, however, the 2nd law of thermodynamics kills that idea. An expanding universe from a singularity not only does
not suffer from this problem, it conforms to all observations.
It's a tough model to circumvent on the science front. Religion, of course, provides an expanded possibility set, but those can't reside in science.
Note: if this thread should ever get beyond the singularity and the expanding universe description (in the book's introduction) and begin discussing the actual science in the thesis, Hawking references Maxwell's equations and their impact on science, and I'm looking forward to popping that out of my back pocket for a nice sub-thread.
