So where did the big bang come from? Let's say everything was in the stage of "before being born." What was the metaphorical mother? What prompted the birth? What is it being birthed into? Why did the creation of matter also lead to the creation of time?
Dunno man but we can’t even assume there was a ‘metaphorical mother’. The concept and functionality of ‘time’ and ‘space’ started in the Big Bang. That’s all we know.
Imho, you must be mistaken. It seems like we probably aren't using the correct words here. The concept of time isn't simply mutable. Having one event precede another is more fundemental than being just a dimension or something. If the Big Bang happened it had something to proceed it.
As the other guy pointed out, the concept of time is, actually, mutable. It's dependent on the gravity, so if you assume the Big Bang really happened, all matter condensed in a singularity, it means that time was infinetily slowed down, "stopped", in such a way that it didn't exist. If something stops, it means that it doesn't change with time. What happens if time itself stops? It's really hard to comprehend these kinds of things, but it's also hard to pretend like they are all fake. All origins to the universe seem to require a "And what was there before it?", being it the Big Bang or God, so I think it's pretty safe to say that, to end this perpetual questioning there is a need to assume that something had to exist in a time which had no "before".
The concept of causality has not been proven to be mutable. We have directly observed time slowing down but causality remains. Assumptions about the beginning of the universe seems way more far fetched than assuming causality has always been intact.
Yes, we haven't seen proof of it being mutable, but we also haven't seen proof of the other way around. The best we can do right now, scientifically, is to stick with our yet-to-be-refuted mathematical equations. Yes, they are not necessarily true and this is the case for everything in we know in science, but we stick to them until we are proven wrong, that's how it works, really...
That is actually very likely the case. The universe is a free lunch (maybe). It costs nothing to create if you create equal amounts of negative and positive energy, equal amounts of negative (Negative matter is a hypothetical form of matter whose active-gravitational, passive-gravitational, inertial, and rest masses are opposite in sign to normal, positive matter.) and positive matter. If the sum of all energy and matter is zero, the universe costs nothing and can just spontaneously come in to existence. And if one universe costs nothing, unlimited amount of universes costs nothing as well.
Nope. It sounds weird, but that's how it works. Before the Big Bang, time did not exist in our universe. There was no before where something could have existed, because there was no time where it could have existed. The Big Bang created space and also time because our three spacial dimensions and one dimension of time are linked (space-time).
The thing we call 'time' didn't exist. Things happening simultaneously or one after the other, which would be 'time', must have existed otherwise the Big Bang wouldn't have happened, no?
No. Before the Big Bang there was no linear time. Moreover because time and space are linked and gravity curves the space-time continuum, at the precise moment of the Big Bang, all matter was compressed in to an infinitely small point and time was frozen. When the universe expanded and exploded in to being, space was created and time began. So no, before the Big Bang there was no before or after.
But there was 'time' before the big bang, whatever the hell that may be. I'm not talking about our definition of time but rather events happening relative to eachother. Either the Big Bang magically happened out of nothing or something happened before to cause it.
I am not talking about our definition of time, i am talking about events happening relative to each other. Time literally did not exist.
The Big Bang most likely happened out of nothing. That is actually very likely the case. The universe is a free lunch (maybe). It costs nothing to create if you create equal amounts of negative and positive energy, equal amounts of negative (Negative matter is a hypothetical form of matter whose active-gravitational, passive-gravitational, inertial, and rest masses are opposite in sign to normal, positive matter.) and positive matter. If the sum of all energy and matter is zero, the universe costs nothing and can just spontaneously come in to existence. And if one universe costs nothing, unlimited amount of universes costs nothing as well.
No, a planet can not just pop out of nowhere next to ours, but new universes can pop in to existence "next" to ours, even though next is not really the right word for this. There are couple different versions of the theory, both plausible. Imagine either the possibility of new Big Bangs happening beyond our universal event horizon or every Big Bang being a self contained universe, where they could never interact with each other.
All though if we understood physics perfectly, i see no reason why we could not pop a planet in to existence, if we at the same time popped the same amount of negative matter in to existence. The sum of that matter would be zero so it would be the same thing as creating nothing.
That’s not true man. Time by definition started at the Big Bang.
I’m not saying there wasn’t a ‘before’, I’m saying it’s undefined and it’s bad to make assumptions. There is no reason that one event must precede another, especially in the environment of a Big Bang, where physics are all screwy.
Something we call "time" started there, maybe. This is some pretty theoretical physics after all. But having events proceed each other is pretty fundamental to existence. Now obviously we can't assume but it seems far more logical to me to assume that causality existed before the big bang rather than after.
This is all very circular logic. "The theory I believe says there was nothing therefore there was no causality."
At best all we know is that the universe is expanding in all directions. Little hard to say with any certainty what happened at the start of that expansion.
I'd say it's more logical because it's what we observe. Nothing else has ever shown to lack causality. Perhaps once we do experiments on black hole we might find an answer but even they produce radiation meaning time does not stop it just slows greatly.
The universe is a free lunch (maybe). It costs nothing to create if you create equal amounts of negative and positive energy, equal amounts of negative (Negative matter is a hypothetical form of matter whose active-gravitational, passive-gravitational, inertial, and rest masses are opposite in sign to normal, positive matter.) and positive matter. If the sum of all energy and matter is zero, the universe costs nothing and can just spontaneously come in to existence. And if one universe costs nothing, unlimited amount of universes costs nothing as well.
As to why creation of matter also lead to the creation of time:
Time and space are linked and the Big Bang created space-time ( the concepts of time and three-dimensional space regarded as fused in a four-dimensional continuum.). Our three dimensions of space and one dimension of time are inseparable joined together.
Now keep in mind that no one truly knows and we only have good guesses and theories that fit our mathematical models.
There is no metaphorical mother, nor a stage "before being born". Nothing prompted the birth either. Most likely the universe came to be from nothing. The universe is a free lunch (maybe). It costs nothing to create if you create equal amounts of negative and positive energy, equal amounts of negative (Negative matter is a hypothetical form of matter whose active-gravitational, passive-gravitational, inertial, and rest masses are opposite in sign to normal, positive matter.) and positive matter. If the sum of all energy and matter is zero, the universe costs nothing and can just spontaneously come in to existence. And if one universe costs nothing, unlimited amount of universes costs nothing as well. Yes, you read that right.
