Every metaphor is a trap-- ether, photons, phlogiston...
Make the math work and reality will map the numbers.
So far, anyways. ;^)

Does this explain why I can see fish better when I have my polarized sun glasses on?
I'd rather broil them, than microwave, though.
(Catchy name, BTW - back in graded school, a bio. on PH was the first book of over 300 pp. that I ever read --and enjoyed it even....)

Why are we here? There is a single question that can be asked on all of those levels and more.Yes, but to confuse the levels serves neither philosophy/religion nor science. Your denigration of science does not make your philosophy attractive.

When time periods get small enough, the very nature of before and after make no sense because on uncertainty principles. Which doesn't bear on larger periods of time, I take it. Or should we use the uncertainty principle to understand that everything in the cosmos, past, present, and future, is somehow happening simultaneously?

nanrod said: "...having everything, all the mass, energy, and everything in the universe collapsed to a point would be the ultimate black hole. "
Hawking predicted "radiation" from black holes due to the creation of virtual particle-antiparticle pairs at the event horizon. One of the pair would be swept into the black hole and the other would move away. In this way, black holes "evaporate" over time.
If the entire universe collapsed into a small enough region, the "Hawking radiation" which would result would probably be of sufficient magnitude to reverse the collapse, just as the Big Bang theory proposes.
For those who believe in a Supreme Being, it is only necessary to believe that that Being would choose to create a universe with an apparent history going back billions of years which is consistent with scientific observation. Is that really so difficult that a Supreme Being could not accomplish it?
For all I know directly, the entire universe was created when I was two years old. Every occurrence older than that was only reported to me by others.

We will never know why simple things like gravity and magnetism work let alone the real natural mysteries of the universe. BW, I'm a disciple of our Lord too, but I've got a problem with this. Just because there's a God doesn't mean science isn't worth pursuing. And your statement above... the one I quoted... reminds me of what people used to say about air, or the mathematical concept of zero, or the human circulatory system.
Just because "Why?" is the predominate question doesn't mean "How?" is pointless.

I think this is one of those things that "I'd like to study up on some day." ;-` I should really catch up on my fishing, maybe, first.

What caused the big bang? 23 posted on 12/20/2002 1:31 PM EST by biblewonk
Let ... THERE (right there, where/when the bubble began the expansion) ... be light. The Creator issued the command that brought about a conjunction of space and time, two of His dimensional qualities, and started the entire shebang. Later, much later by our reckoning, He involved another of His dimensional qualities, LIFE, and the lifeless took on awareness. Even later, He issued another integration of a dimensional quality He possesses, and spirit entered into the mixes of dimensional expressions.

Just because there's a God doesn't mean science isn't worth pursuing. I never said that, but in titus 6:20 the 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.
To: RightWhale
This happens as relief to stress in the cosmos and it will never end. Our own personal BB ocurred 14 billion years ago. Nothing special. Current thought on the subject. 40 posted on 12/20/2002 1:56 PM EST by RightWhale Questions for you, RW: these stress relievers occur in the spacetime bubble of our reality or outside of it, then intersect our spacetime to then disappear? Our 'BB' brought space and time into being, or the 'BB' happened in an already existing spacetime background?

Well, maybe it does, and maybe it doesn't... but if you don't mind my asking, do you have the qualifications to make that call?
The question is kind of irrelevant anyhow, because whether the universe Big Banged or not, science can get no grip on the whole notion of why it happened. It's not what science is about. By the same token, I find scientists who disbelieve in a Creator on the basis of their work to be as laughable as a mechanic who disbelieves in Henry Ford. "Been lookin' for his fingerprints for years," he might say. "Never found 'em... NOT EVEN ON FORDS!!!"

I like the analogy of a line, a plane, and a hemisphere to visualize past, present, and future. Because we exist on the plane of present, our 'view' is limited to the plane, while in our past, only one intersection with the plane is possible, from our reckoning, and from the point on the plane (our individual where/when) that is our now, think of how many vectors many be extended off of the plane into the hemisphere ... and each of these vectors will be the linear past when we move to the next present plane, and the next and the next.

Jesus and John the Baptist are not qualified to preach in most of the Christian churches in this country. College is a joke, been there and see the results of "higher education" in my peers.

these stress relievers occur in the spacetime bubble of our reality Would be inside our continuum, and then something clicks and it's gone, taking the stress with it. But whatever causes the stress is still operating, so stress continues to build until *Pop* it's gone again. Like sand bars in the river.

College is a joke, been there and see the results of "higher education" in my peers. On the basis of our brief interaction I would guess that you have been both resolute and successful in resisting its insidious effects.

The notion of a big bang is way beyond ridiculous.Then why do you suppose that so many of the most brilliant minds in science have devoted their lives to studying it?
Several people have mentioned this on FR but the evos here do not appear capable of absorbing it or handling it: having everything, all the mass, energy, and everything in the universe collapsed to a point would be the ultimate black hole.
Tell me, what is the total energy of the universe? What would you say if I told you that it is something very close to zero?
Nothing could bang its way out of that, big, little, or otherwise.
What makes you think we are out of that? According to inflationary cosmology, we are in a black hole right now.
The whole notion is idiotic and PatrickHenry and several of these people who make all the noise on FR on these topics are basically a bunch of idiots.
It's aggressively ignorant statements like that that make FreeRepublic--and conservatism in general--into a laughing stock.
To: Physicist
Always a pleasure to read what you have to say, Physicist.
To: nanrod
How about the great chicken created the universe 100,000 years ago today? That's not really GOOD, but it's better than the "big bang"; that isn't asking for much. How about the universe has simply always been around and will always be around? 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.
