I understand what your saying, but your concept has a very large hole, lets follow your logic and see whats missing. So before the big bang there was no time, time did not exist, so there was never a time when there was nothing.
Yes
That is what your trying to say, but look at the next step and this is where your problem comes in. So let's continue your logic at time zero, the time when the big bang began, when time began, then matter began, but where did it come from, how did time begin, what brought about time, it still requires some past energy or matter,
It could have been caused by a random quantum event, or by a number of other things...I am no physicist, but the point is that
matter does not have to exist stretching back for an infinite amount of time in order to satisfy the 'matter cannot be created' part of thermodynamics. The linear time that we experience is something of an illusion, as time in physics (as far as my understanding goes) is relative and finite (as are the first three dimensions, I believe, according to quantum mechanics)...not the infinite linear continuum that we think it is.
if there was ever a period when there was no time because it did not exist then we would not exist. existance of energy or matter requires a beginning by your logic. there can not be a time zero,
You are forgetting that time is not linear-- it is a relative concept that can have a beginning. We humans experience time as linear, but time is not linear, it is actually the fourth dimension and is used (as are the first three) to describe the position of an object in space. The Big Bang occurred at a position in space where time equals zero.
it is impossible because there would be nothing to bring about a time zero, what started the big bang?
There never was a nothing to bring about the big bang. The universe has always been. Reread number 4, and keep in mind that time is not an infinite linear continuum.
that why you can't find any scientist that subscribe to your idea, because it is impossible, wether you say time existed or not, your idea says the big bang was caused by nothing.
There could have been a number of causes, such as a random quantum event. String theory is another possibility, though I do not know much about it. The point is that something can seem to us to 'come from nothing' (like the Big Bang) when in fact we are only fooled by our human perception of time. And I never said there is no explaination for the Big Bang....only that matter can 'come from nothing' without violating thermodynamics (if the time that elapses 'before' the matter is 'created' is equal to zero).
that's why scientis are exploring the idea of the expanding universe that perhaps it is expanding out then will eventually collapse on itself and form another big bang, because they understand the fundamental concept that matter can not come from nothing.
What you are talking about is the closed-universe theory. Most scientists think that we live in an open-universe (that the galaxies will never come back together to form another big bang). This is because the calculated velocity at which the galaxies are traveling away from each other is increasing, not decreasing.
if you still wish to hang on to your theory answer that question for me, what started the big bang?
This is a very difficult question which requires a very complex answer. There is still a lot we do not know about the big bang, but one thing is very clear--it did occur, however the method.
My point is that just because there was possibly nothing "before" the big bang does not mean it violates thermodynamics, given our modern understanding of time.
One more thing--if I am misinformed on anything, please feel free to correct me.
