For lack of a better way to phrase it, there it is.

Human language cannot well describe a 'time before' there was no 'Time', (and hence no 'before').

Likewise, there is not adequate language to describe 'where' something was if there was no 'where', i.e. Space did not exist.

So, if you'd like to furnish empirical evidence that the hypothetical singularity did not exist 'until' the BB, and the nature of the 'where' that it came from, go for it, Chumly.

Otherwise, you're simply defending a guess (the BB) with another guess (there was no Space/Time).

real, I don't have a need to cherry-pick from that link; I believe all of it. On the other hand, you have a problem with BB, so you're the one that needs to cherry-pick and challenge what it says. I'm sure I'm not the only one who wishes to see your challenges to that article.

You 'believe it all', eh?

Very aptly put, CI.

But are you sure you do?

Better make sure your denomination has given it's approval to the presentation in this particular document before giving it your unqualified faith and blessing, CI.

A common problem with BBers is that the advocates of competing versions of the theory both like to use 'Big Bang' to describe their version, and pretend that there is no other version.

In reality, some BBers think that the universe came into being at the BB --- or they may , as your link details, think that the universe is essentially eternal, having 'come into being' at NO point.

So which is it for you, CI?

Was/is the universe 'eternal' -- with no beginning point, simply reshaping and reorganizing matter/energy in various combinations eternally into the past and future?

Or did the universe 'come into being' at the BB?

These are essentially philosophical differences and are supported by inferences drawn largely from circumstantial evidence; since neither side has empirical (i.e. scientific) evidence of what actually took place eons ago, since there was nobody there to observe it.

An example, the universe appears to be expanding, so it is inferred that it 'exploded'. An unwarranted assumption, since something can easily expand without having exploded.

real, You're talking philosophy about the BB is fruitless; it's a scientific theory.

are you aware, rl, of some of the evidence that has been forwarded that is consistant with a BB?


Hi Farmerman,

Just as with evolution, I think that the majority of evidence that I have seen to support the BB tends to be circumstantial and (rather weak) inferences are put forward and treated as if they were conclusive proof.

If you've got something specific in mind, I'd be glad to discuss.

From your link , CI:

Quote:
1) What is the Big Bang theory?
a) Common misconceptions about the Big Bang
In most popularized science sources, BBT is often described with something like "The universe came into being due to the explosion of a point in which all matter was concentrated." Not surprisingly, this is probably the standard impression which most people have of the theory. Occasionally, one even hears "In the beginning, there was nothing, which exploded."

There are several misconceptions hidden in these statements:

---The BBT is not about the origin of the universe. Rather, its primary focus is the development of the universe over time.

---BBT does not imply that the universe was ever point-like.

---The origin of the universe was not an explosion of matter into already existing space.

The famous cosmologist P. J. E. Peebles stated this succinctly in the January 2001 edition of Scientific American (the whole issue was about cosmology and is worth reading!): "That the universe is expanding and cooling is the essence of the big bang theory. You will notice I have said nothing about an 'explosion' - the big bang theory describes how our universe is evolving, not how it began." (p. 44). The March 2005 issue also contained an excellent article pointing out and correcting many of the usual misconceptions about BBT.



Do you support this version of the BB?

Do you believe the BB does NOT describe how the universe began?

Actually that's called the Steady State theory (the eternal one).

Bob Wilson, the guy who discovered the Microwave Background Radiation (CMBR) originally preferred the Steady State theory, but changed his opinion (grudgingly I think) after his own discovery.

By the way, go ahead and use the CMBR as a piece of evidence which supports the BB theory. If you want to challenge one, you might as well start with that one.

You always get hung up on observation. Observation of an event is not required to prove (scientifically) an event. Only observation of the evidence is required.

I can observe a burned out car by the side of the road. But if I didn't observe the event itself, the car is circumstantial evidence. I need more evidence to say how it got that way.

Objects in the universe are observed to move away from each other, but to say conclusively that it is due to an 'explosion' is an inference. The evidence itself is circumstantial.

Alright, show how CMBR could ONLY have come from an explosion of a 'singularity' which existed 'before' the universe did.

(Simply responding 'well where ELSE could it have come from?' really doesn't get you too far.)

Here we go again, the old, "I have no evidence to support anything I say, so Ill try to trash yours". When did this topic morph from evolution to cosmology?

Circumstantial evidence becomes compelling when theres
1lots of it

2Nothing to refute each piece

3No similarly evidenced explanation exists.

All evidence is circumstantial, otherwise it would be the event itself.

I'm sorry you're not happy with the way science works.

I hope I don't lose too much sleep worrying about you tonight. Smile

Not so as physics can demonstrate that without mass-energy there can be no space-time. Again your presumption of causality is false.

That's not how science works.

The way science works is that you give us a different scientific theory which matches the evidence of the CMBR and ALSO matches all the other evidence (as the BB theory does). THEN we take you seriously.

Otherwise, how can we differentiate you from any one of countless nutcases with a pet theory?
