Knowing that our universe is constantly expanding and therefore by reversing the process we accept that the universe began following the Big Bang from this point of singularity.
Are we able (or has anyone been able) to calculate where this point of singularity occured?

It occurred everywhere. Every point in the universe is moving away from all other points. Going back in time until the big bang, all points move closer to eachother, until they are (almost) infinitely densily packed.Originally Posted by Chris B

I've told this a lot of times before but no matter, I'll tell this again (seeing as we have quite a few new members on board and all): the Finnish astronomer Esko Valtaoja likes to say that the Big Bang occured at the tip of his nose. You can see it in this pic:
Otherwise, it's as Slang said. If you are thinking about the famous balloon analogy, then the point from which the balloon expands is a point in time (the lowest possible limit to which is known, probably fairly accurately) and the surface of the balloon of a 2D representation of the 3D (as in spatial dimensions) universe.

All the talk about the Higgs Boson has got me thinking:
Has the Higgs Field been absolutely constant since a fraction of a second after the BB?
Is it possible that the mass of a certain object is larger in the past than in the future (because the Higgs Field is getting attenuated with universal expansion)?
When we look to cosmological distances, are we seeing regions where the Higgs Field is denser, and therefore matter has more mass?

I don't think so. There are likely ways to falsify such an idea. It would, however, help to explain how early stars and galaxies formed earlier than expected.

Why is that? You assume there was only 1 BB, and only 1 universe. How do you know there werent BBs after some other BBs?
What if the other universes are as well created by BBs? Maybe a BB(or a hundred) occurred after the one that created our
universe.
If there are billions of galaxies, why cant there be billions of universes? Also, why wasnt there a universe prior to the BB?
For the BB to occur, something must cause it; otherwise, the universe would have been at rest or at the state it was prior
to the BB. Ok, so how long was it before the BB occurred?
Maybe a BB is just a black hole that eventually blew up all that it had swallowed.

It all boils down to evidence. We have evidence of one universe. We have evidence of one BB. We have zero evidence of anything else.

Not really. We have evidence of the observable universe expanding from a hot dense state. That is about it. Anything out side that is speculation because we have no models to describe what went on before a short period after the lines on our graphs converge.We have evidence of one BB.
And maybe it was Arkvoodle jump starting his car. Equal amounts of evidence for either speculation. We do not have the physics models to probe that far back in time, simple as. We have a few ways to constrain what has happened but that is about it.Maybe a BB is just a black hole that eventually blew up all that it had swallowed.

Really? I have never seen any positive evidence of the BB. In fact many theorists are now doubting the BB all together. The posibility of God existing has the same EXACT probability of the BB theory.

Would you mind posting your statistical analysis that shows that?

The point being is that a simple Google search is all that is needed to show that what I claim is FACT. I stand by my statement.

3 for 3 utterly false statements. You appear to be on the wrong website.

This article is titled "Big Bang Theory Busted By 33 Top Scientists."
The first "top scientist" listed is.... Eric Lerner. Eric Lerner has a bachelor's degree, then he dropped out of grad school. Eric Lerner is about as far from a "top scientist" as you can get. I notice Halton Arp is also listed. Arp was a fair scientist 20-30 years ago. Then he turned in his card and became something else - not a "top scientist."
You're not going to seriously discuss any of this, are you, Randy?

Slang's description is correct. We do not and can not know about other BB Events. Even if there was something before the BB the BB is a vale we currently can not peer through so doing so is more philosophical then science.
Also it is a logical logical fallacy to say that for the BB to occur something must have caused it. If you ask a question about before the BB that is one thing because the BB came from a pre-existing condition. Where that came from ... who knows but science is pointing to the fact that there need not be a cause and if you talk about before time and space then causality has absolutely no place there.
regardless everything we see seems to have come from the same big bang. Basically our whole universe emerged from a single event and we may never know anything about "before" that event if that is even a valid question in the first place.
