Being a smart-aleck, the next question I'm likely to ask is "What happened before that?"

BB Cosmology involves the idea that space AND time come into existence concurrently at t=0. Therefore, by definition, there is no such thing as t<0. Hence, there is no "before" the BB, as the word "before" presupposes the ability to establish temporal order, and if there is no "time" then there can be no temporal order.

The standard way of illustrating this is to use the analogy that asking what is "before" the BB is like asking what is North of the North pole, or what is colder than absolute zero.

How about the universe has simply always been around and will always be around?

Because nobody's figured out any mathematically workable model that is consistent with the observed data.

Why do you need these beginning myths? Oh, the "expanding universe" you say? Turns out, at least from what I hear, that one's a myth too.

Well, you heard wrong, because the expansion of the universe is an observed fact. Even the old, failed "steady-state" models exhibited cosmological expansion.

Well, of course. It would have to.

God points out that there are things passing themselves off as science. That's pretty much what we have here when we see a 1 part per 100,000 difference in the distribution of background radiation at 2.7ish degrees K and conclude that it supports the big bang theory.

That you can't be bothered to do the math is a poor substitute for a valid critique.

The other quantum events that occur as 'BB's' that flash out of our universe, do those happen in a field of spacetime, our spacetime, even if only for a moment? If so, would that infer a background dimensional field out of which our 'BB' bubbled?

I never said that, but in titus 6:20 the God points out that there are things passing themselves off as science.

Really? It says that? I seem to be fresh out of Bibles with that mysterious sixth chapter of Titus, and I can't seem to find it online anywhere. Now, I'm no Bible wonk or anything, but maybe someone's slipping stuff in when you're not looking?

It would be very difficult for me to say....

Do you have any evidence of that OTHER than redshift?

Good post! Another victory for the scientific method. The anti-science cre-IDs are going to be upset again.

That's their destiny. They love it.

That would explain how the distance between myself and my exwife has been constantly increasing.

And also why the pants of my old Army uniform no longer fit.

You stated yourself earlier in this thread that you used to be a "materialist in Sagan's church" ...

It's part of some kind of mantra they get from somewhere. I'm embarrassed to say what it reminds me of, but I won't let that stop me, of course.

In my misspent youth, I used to go in strip bars sometimes. (Blush!) The girls would try to talk to me and hustle me for some very expensive drinks. Would you believe that every one of those girls had just broken up with her boyfriend in the last week/month? Probably still true today, although my personal survey of the subject ended about 20 years ago.

I'm told--haven't checked this one out personally--that every criminal in the State Pen was framed, too.

Incredible numbers of the creos used to be evolutionisits until their minds expanded and they began to question. (If these are questioning minds, I'd hate to see "doctrinaire.")

I tend to put my old Air Force field jacket on when I wash my car in cold weather. (Said jacket and a blue raincoat being the last useful residues of my time in the service.) I just noticed today that the field jacket seems to have undergone some kind of thirty-years delayed shrinkage.

Yes. We can look at the time evolution of the most distant type Ia supernovae (in other words, how they increase and die off in brightness over time). These supernovae should follow the same profile over time, all over the universe. But supernovae that are receding from us rapidly will brighten and dim more slowly, for two reasons: the Doppler effect and time dilation. As it turns out, both of these effects are measurable in the distant supernovae and are in good agreement with the observed redshifts. There is no doubt that they are receding from us in a manner that increases with distance.

Yeah, like all those brilliant "scientists" at places like "Creation Research Institute" who used to be "darwinists" until they discovered Noah's Ark. Funny thing about those scientists ... they never seem to make any scientific discoveries. I wonder why that is.

I have a theory, of course. When you buy into "Goddidit," you don't want to hear anything else. Doesn't give you much to offer to the advancement of discovery.
