Every time you see a diagram, an article, or a story talking about the “big bang singularity” or any sort of big bang/singularity existing before inflation, know that you’re dealing with an outdated method of thinking. The idea of a Big Bang singularity went out the window as soon as we realized we had a different state — that of cosmic inflation — preceding and setting up the early, hot-and-dense state of the Big Bang.
Sigh. Because we what happened before cosmic inflation is unknowable, it’s another hook creationists will hang a “Creator” on.

He’s right about the BB being more pop culture than anything real. It’s a hypothesis. Not exactly sure why he’s saying singularities are impossible, though. Black holes (both spinning and fixed) will produce them. The simple fact is we have absolutely no idea what was happening before inflation.

From what I read in his piece, a singularity is not possible in an inflationary model.

Right, because of the dispersion of heat as recorded in the W map. Saw a good line on Twitter the other day, and it rings true:
“The universe didn’t have a beginning. It had a change of state.”

We can’t be entirely sure, no. But the BBT does a fair job of explaining the things we do know. The measurement of the Cosmic Microwave Background went a long way to support the theory.
If religion had half the data supporting it as does all of science, a few more atheists might well be believers… 😉

Certainty is impossible. The cosmic microwave background only explain events after the beginning of inflation. It doesn’t go beyond that and I think this is his argument

You’re right, everything up to a point can be explianed, and it certainly seems intuitive that on the other side of inflation was a singularity (perhaps housed inside a black hole from a collapsing 4D star) then the bloody physics breaks down.

I’m not sure I buy the argument that human consciousness somehow “creates” the universe. Does the act of observation in itself create the entity being observed? That seems rather desperately arrogant. And it ignores a vast universe out there beyond our observation. It also veers rather closely to the Christian “God created the Cosmos for us” theory only with arcane math rather than Scholastics debates about angels on pins. It also easily allows the nonsense of Quantum Wood promoted by the likes of Deepak Chopra and his ilk.
I have no problem with punting on the question. Why does there “have to be” a “matchmaker”? Maybe the universe just IS?

Does a tree falling in the forest make a sound if there is no one to hear it? I think the question of consciousness creating the universe is in the same class of thought exercises

My response — Didn’t cosmic inflation go out the window when we realized we were a simulation 😉

Does having a simulation rule out inflation?

You asked — “Does having a simulation rule out inflation?”
My answer — Yes. It would mean that what we are seeing is only code changing the positions of ones and zero’s in memory.
Science would then have to change to predict program code and not physical space.
