"cosmic dust(or something)" just appeared out of nothing and exploded. like how does that even make any fucking sense | ||

We expand then collapse over and over and it is infinite (it obviously takes huge amounts of time for even 1 cycle though). So it always was and always will be, just in different forms. But anyways, when compared with other accepted theories (creationism for example) they have huge fucking flaws in them as well. Where did god come from? Who created him ? It's the same shit, really. Nothing is 100% fact, you just gotta take some of it on faith. PS- if you watch the above video, this is an even better theory imo, he suggest that blackholes perhaps suck in tons of crap and eventually just explode into 'white holes' on the other side creating a whole new universe, and this cycle is ongoing as well. So in lamen's terms its mini big bangs going off billions and trillions of times from blackholes creating new universes all the time. | ||

The theory is relative to the universe evolution, not to the causes. We just cant know, we cant messure time or distance, two concepts that are part of the universe itself and the base for physics aswell. Before the bigbang it cant be physics as we know them, so we cant answer that. Go and ask your favorite priest. I just read the whole thread and have to say many things here are in fact the accepted big bang theory, but i want to make a few observations: I am most into chaotic inflation theory of the multiverse, that is just an extended system of big bangs not lynked by causality. This is exactly many parallel universes that could or could not have any space/time or energy related situation. When we talk about parallel universe we need to focus them as physic realities or then we wouldnt talk about them while doing physics. The quantic particles sometimes just arent where they are supposed to be, and therefore the distance (position) doesnt just relate to time, its actually the result of a chaotic equation. Is more accurate talking of something that is probably there than something that is actually there. This could only be truth if we think that space/time is in fact discrete. In the thing related to light speed, it is a natural limit to any information traveling, of course that is inside our universe. so the furthest things in the universe to the earth are going away exactly at this speed. Anything that moves faster is in fact outside the universe rules. The thing is that here we are talking about relative speeds (like always, in physics everything is about delta when modeling shits) Finally each universe has a set of rules that put them in a markovian space. This is we just need to look where we are now to know the evolution, the past will be always a mistery. | ||

Nothing is 100% fact, you just gotta take some of it on faith. Two things: The big bang theory actually only descrives the expanding part. The colapsing part are less accepted interpretations, is a nice idea to think that things that have a beginning should have an end, but we cant know that for now. Cosmic time is so out of our scale. I just decided not to write was i wanted to write, because as i said before i think this thread is not for that. Can we keep it on physics? oh, yes, and third... is 100% fact that universe is expanding. the light as mechanic wave (it is both, right? mechanic and electromagnetic, thats einstein) is succeptible to doppler effect, that means that the color of a star deppends lineally on its speed, and can be proved that further stars moves faster than closer stars. Lynking this two facts you have only one possible explanation, that the space between any two objects in the space growths constantly. Thats the base. | ||

So a=1 for the present universe, and goes down as you go back in time towards 0. It makes things a lot easier since you can easily change from a to redshift, or into expansion rate which is more useful than actual time. Also in the inflation period the universe was expanding WAY faster than the speed of light, so parts of it that were in contact before inflation suddenly couldn't see each other. As the expansion slowed down they started drifting back into contact but it explains the large scale patterns in the universe As for where it's expanding into.. yeah.. it's like the balloon. But what if "time" = the scale factor? E.g. 1 second = "1^150 more stretching"? Although it wouldnt make much sense if the strech wasnt linear as you described. Is it decreasing though? Or increasing - like U pattern. Personally I have this theory that you cannot go back in time because: a) time = stretching of the universe b) the same atom cannot be at the same spot at the same time (ok, they talk about the quantum bubbles, but these are not the same atoms) - think of it as a giant database There's actually a theory that the direction of time is tied to the expansion of the universe. So when the universe contracts, time actually reverses and everything starts going backwards. But I don't think it's popular, since there are processes that are time-dependent that aren't tied to expansion. If time went faster when the universe was expanding quickly, everything else would move faster as well so it would cancel out. The actual equation relating time to the expansion rate is pretty complicated, and depends on whether the universe is dominated by radiation, dark and regular matter, or dark energy (one interesting thing about cosmology is that the "standard" theories are based on the existence of dark matter and dark energy, which have never been detected and no one knows what the hell they are).

But I'm definitely not saying that, people can take an interest in whatever they want. It's just going to be really confusing, like trying to understand builds without having played starcraft. | ||

But for our universe none of these things really apply since the limit for how far we can see is the cosmic microwave background (basically the glow from right after the big bang) So in theory if we had a telescope that could see through all the stuff in the way we could see the big bang happening.

The end of time and beginning of time is actually going in the same direction as it expanding. When you move from one place to another, its actually the 15th dimension that is moving with you. If we look at the 2 slits experiment, there are actually 12 explanation for it. One of the explanation is that there parallel universe and maybe infinity of universe if you see it in dimension 7. In order to understand the larger picture we need to understand the fundamental parts of the universe. Super string theory explains the universe in only 10 dimensions. You need to get to 16 dimensions. The thing is our brain needs to imagine the 16 dimensions. Since we only experience the 3rd dimension, we think in the 4th dimension. In order to get to higher dimension, we need to use drugs to open our brain up. I would suggest taking a large amount of weed to understand parallel universe. One time I ate brownie and got so high. I was between two universe. Two of my conscious mind were connected into one. At first I was jumping from one mind into another but both of my minds joined into one. Also if you think about how our brain creates reality. What if our brain is what keeping us in this universe. If we were to released from our brain could travel into other universe with our consciousness. I'm planning to study more about physics and possibly find a way to travel between universes. lol. I love this post. About the most interesting troll I've read so far. | ||

Is when you model a state for something and add the generation variable and all that you need to know the next generation state is the actual generation state. In a simple way think in any square matrix and start multipling by itself. Not like a potence, actually by itself on any generation. Of course a matrix isnt either complex or interesting. Conway's game of life is a good example. The thing is you cant really go backwards, because many different states could bring you to the same state, like we cant really know what is before the big bang. | ||

Up until a decade or two ago this was a very serious contender... but more recently it's been demonstrated to be highly unlikely. | ||

You. Thanks for copy & pasting the difference between a law and a theory. I'm sure that clears up everyone's misunderstanding... Or, perhaps you could realize that most people here have graduated elementary school and you probably don't have to spout inane elementary bullshit. Being dismissive of the big bang theory is generally harmful to cosmology and other relevant fields. Scientists may not be absolutely correct in all aspects of the big bang. Historically, scientists learn the best they can in in their given environment. There will never be a point when we know everything. As we know it, the big bang is the best possible catalyst for the creation of our known universe. Scientists are not prophets, they are never infallible or completely correct. That doesn't mean that the collective understanding of the universe that mankind has compiled since we first started writing shit down is worthless.

It can account for some of the more peculiar aspects of the universe, particularly its large scale homogeneity. Educate yourselves. | ||
