Frank Tipler actually produced a simulation argument as an endorsement of Christian belief. Along with some interesting cosmology making it possible for this universe to simulate itself! (It's easy when the accessible quantity of computronium tends to infinity as the age of the universe approaches its limit.) In Tipler's theory, God may not exist yet, but a kind of Singularity will create Him.

Of course, the average Christian has not yet heard of Tipler, nor would said Christian accept the endorsement. But it is out there.

It's worth pointing out that we now know that the universe's expansion is accelerating, which would rule out the omega point even if it were plausible before.

IIRC, Tipler had that covered. A universe of infinite duration allows us to use eons of future time to simulate a single second of time in the current era. Something like the hotel with infinitely many rooms.

But please don't ask me to actually defend Tipler's mumbo-jumbo.

I don't think it can be defended any more. I picked it up a few weeks ago, read a few chapters, and thought, do I want to read any more given that he requires the universe to be closed? Dark energy would seem to forbid a Big Crunch and render even the early parts of his model moot.

Sweet! Wikipedia's image for Physical Cosmology, including your Dark Energy link, is the cosmic microwave background map from the WMAP mission. That was the first mission I worked with NASA. My job, as junior-underling attitude control engineer, was to come up with some way to salvage the medium cost, medium-risk mission if a certain part failed, and to help babysit the spacecraft during the least fun midnight-to-noon shift. Still, it feels good to have been a tiny part of something that has made a difference in how we understand our universe.

Disclaimer: My unofficial opinions, not NASA's. Blah, blah, blah.

I think you duplicated my post.

So I did. Context in Recent Comments unfortunately only reaches so far.
