What happened before the Big Bang? Was there just matter about or was there a big bang before the big bang?

I think there are some theories out there that there is a big bang, the universe expands, then it contracts until its a singularity again, and then the process repeats itself..
this scares physicists(hawkings at least), before the big bang there was imaginary time.Originally posted by dav2008

scared of the notion of an ultimate beginning, i think so, mainly because a beginning points to a creator. I am still not too keen on the specifics of imaginary time. is it infinite or finite? and how can one justify this?Originally posted by DrChinese
Before the BB: there be dragons...
I doubt you will find many scared physicists, least amongst them Hawking.

How can everything come from nothing, that's an oxymoron
There was nothing before the big bang..the answer is correct if we agree "that everything came from nothing because its the only thing that do not come from anything" and if we agree to the answer that there was something (anything!) before the big bang then still its true as things are true till they are not proven worng...sOOO
Well, its the starting point for human brian as none of us could have peeped in the period before big bang...

the only reason the BB doesn't point to a creator now is because of the imaginary time theory and the no boundary hypothesis.Originally posted by DrChinese
First, there is nothing about the Big Bang that requires a creator. Or even points to one.
Second, so what if God created the Big Bang and has had little or no subsequent involvement in the unfolding of the universe? That is a perfectly reasonable hypothesis. Why would it scare any physicists?

well not scared in a sense of being afraid, but science just will just never accept god as the only answer, they make things logical by adding new terms and new theories. im not saying it's a bad thing, but when you continually invent new theories and ideas just to suit your previous theories i get kind of skeptical.

im not exactly sure, but i believe imaginary time is simply a theory (i have no clue how someone could prove it). therefore, one must think that perhaps it's only relevance would be to make sense of a situation that doesn't make sense. this doesn't flow well with me because it seems like a scapegoat for physics without real proof of any kind. the same thing happens with the weak anthropic principle and very strange numbers such as the cosmological constant.

yes, but can you observe imaginary time as you can gravity? and i far as i know the Earth being round is proven .Originally posted by kyle_soule
The interest thing is, gravity is only a theory too, the world being round is also only a theory.
funny thing is that the "laws of physics not being changeable" is the no boundary hypothesis in a nutshell. if just one point in the universe has a different set of laws the whole theory crumbles (finding that one point(s) would be very difficult though, also i assume if it was proven false another hypothesis or theory would just take it's place). also if god is all-powerful it wouldn't matter what theory you came up with, god could always have created the universe just the way the theory states. it's really an endless argument that as of now shows no clear answer.Originally posted by kyle_soule
If God created the BB this wouldn't really scare physicists, per ce, but it would make the laws of physics changeable, which doesn't happen. Occam's razor apply's to God in science, and as of now we don't need Him.

if god created the universe he would have in turn created the laws of physics. why would god have to create places in the universe that don't obey the same laws anyways? and I am not too sure if i would call the human race a "screw-up", but if you use that logic you could easily see black holes as a screw-up, but really now, both the human race and black holes are spectacular things.Originally posted by kyle_soule
Well, I wasn't sure the Earth being round, it seems to be only a theory, since our space flights are debateable and some people still think the Earth is flat...but I will take your word for it and assume now it is fact
If God created the universe according to the laws of physics then wouldn't the laws have to exist before God? and therefore created God? maybe, I'm not positive about this. The problem with God creating the universe, with a set of laws or not, is that we have never observed a place in the universe that doesn't obey our set of laws, you would think, of course this isn't a sure fire way of thinking, that if God existed we would see that sometimes in someplaces the laws change, if only for a short period of time. He screwed up on man, Noation deluge fixed that, it seems reasonable to assume he screwed up on a much larger scale (with much more room for screwing up) on the cosmo's, so he would simple push that little blue spec a few light miles over to keep it in a nice tight orbit our the sun?
Lets see if I can find it...and schwarzchild how did they come to the conclusion that an alternate universe would have to exist? sounds like a cool idea though, can you post a link to the article?

And just where can we find "proof" of these parallel universes? Certainly not in the sensationalist Sci-American article posted. Even if they were, the first 3 type of multiverses listed still require a beginning. For example, the type one multiverse rests on the notion that the universe is infinite, and so everything possible will happen somewhere. But that infinite universe is expanding and begins with a big bang.
With type 2, you can push back the beginning to the past, long before our universe. But this inflationary universe is still expanding, and sooner or later you'll hit a singularity in the past.

There are actually some very interesting theories involving universes created everytime a black hole is formed and any time there is a big crunch. In other words, when a star collapses into a black hole it creates a tunnel in spacetime that opens a new universe, another big bang. This creates a multiverse. (Of course, since by definition a universe is "everything" by definition the multiverse should actually be called a universe, which is perhaps why a new definition for universe needs to be written.)

The exact cause of the Big Bang is still unknown and is a topic of ongoing research and debate among scientists. Some theories suggest that it was triggered by a quantum fluctuation in the early universe, while others propose the existence of a previous universe that collapsed and led to the Big Bang.
The concept of time did not exist before the Big Bang, so it is not accurate to say that there was something "before" it. The Big Bang marks the beginning of our universe, and it is currently impossible for scientists to determine what existed or happened before it.
The Big Bang theory suggests that the universe began as a singularity, a point of infinite density and temperature. This singularity then expanded rapidly, creating the universe as we know it. However, the exact mechanisms of this process are still not fully understood.
As mentioned before, the concept of time did not exist before the Big Bang, so it is not possible to describe what the universe was like "before" it. The laws of physics as we know them also did not exist, so the conditions before the Big Bang are beyond our current understanding.
It is currently impossible for us to know what happened before the Big Bang, as the event itself marks the beginning of our universe. However, with advancements in technology and scientific research, we may one day gain a better understanding of the origins of our universe.
