Can a theory of everything describe both the beginning and the end of the universe?

The physics behind the beginning of the universe  was probably different than it is today.  For instance the period of inflation was not something that is happening now  Unless the current expansion of the universe is the same thing just slowed down.  But I would say the chances are that even a TOE won't help us understand where the universe came from.

I believe it. I also believe in the theory, in which, as you may also know, whole cosmos is going to turn back into that extra atom. What I wonder alot, when the expansion of the universe will stop and start to shrink back :=)))

I can't say i'm a supporter of either UNS / BigB theories coz both isn't convincing enough to me. Your point here is exactly why i don't believe in UNS, as for BigB, yes your argument does suggest that everything starts from a singularity.. then what is that singularity? Can universe be considered started because of the big bang then? or was that singularity was actually been part of the universe all along? if you think from here further.. don't you think UNS sounds more logical?\n\nall and all.. they're all theories, and believes.. just like we can't prove the theories about Multiverse.

The name for the theory that everything was created 'as is' is the Omphalos theory. I'm not sure about the other, but it sounds like a variant of the 'tired light' theory.

I think space is the container for the matter which makes up everything.  I also think there is more than one container which could potentially be parallel dimensions or other worlds with differenet physical rules.  I think the path to these other worlds lies in what is known as a black hole.  They say the universe is infinite so maybe there are an infinite number of containers which would mean they would never run out and have always existed.  Also, time may not me restriced to how we view it.  Our lives may be just a blink to other worlds or almost infinite to others.  There is no possible way to explain it definately, it is all speculation and beliefs.  One way to expalin it is with religion, but what is religion?  A belief in a greater being with absolute control? Or the belief that the "big bang" theory exists?  They are one in the same a belief nothing more.

The universe will end when the sun and all the stars collapse and engulf everything killing everything and sucking it all into a dot. We will all be dead, so it doesn't matter what happens after that. Of course, we still have a few billion years before that happens, so I wouldn't worry about it. Besides, I believe the Lord will return before then, but the universe will not end at that time, only change.

Even though big bang theory suggests the origin of universe from singularity, there are many questions unanswered. There are theories that suggest that big bang is not the starting point but part of a cyclical process of several big bangs and collapes happening from time to time. The concept and understanding of infinity, multiverse and timelessness are beyond our comprehension and so looks complicated. I believe in multiverse with its own space-time. String theory explains it more. I would think of universe as being a big bubble with its own space and time and when collided with another bubble(another universe) would create chaos (or may be not) and eventually form a new universe. And this might be taking place with several universes at different levels(dimensions). This might or might not be true, but just wanted to throw my thought. Additional comments/thoughts are always welcome.

The universe is full of surprises.  Things have baffled us in the past, and will continue to alter your current understanding of the universe.  The theory of the Holographic universe may be our current understanding that the whole is contained is every part that makes up the whole.  Every atom is a universe, and every universe is also an atom.

The universe is everything that exists.  The opposite would be everything that doens't exist.  So, the opposite is nothing.

Everything started off with The Big Bang. As there is the Big Bang Theory, there is also the big crunch theory if im not wrong. During the Big Bang, the universe is formed and it is expanding. But scientific discovery have showed that the Universe is expanding at a decreasing speed. It will come to a point of time where the Universe will stop expanding and due to the internal gravitational force, the Universe will also start contracting but at a slow rate. It will be really contract really slow at first but the rate of contracing will speed up. Think it as a exponential curve. Yup... Then everything will be suck back to the point of sigularity again and when energy in it becomes unstable it will explode again thus forming the new Universe. But anyway we wouldnt be ard to witness this by then. Not even a million lifetime. HAhahah... So dun worry!

To say universe is infinite is partly correct because nobody has ever found its corner or a boundary. But some ppl think that if u set out in one direction ina hope to get to some end/boundary one day, you might end up turning a full circle without realing so, because space has some really small and complex curves much beyond our comprehension with our present knowledge and intelligence

IN THE BEGINNIG IF THERE WAS ONE>>>>\n\nIn the Beginning, there was no Beginning because at the time, there was no Time. However, our minds cannot grasp a condition of no-time, so let us pretend that there was a Beginning and begin again: \n\nIn the Beginning, there was THAT WHICH WAS, IS, and ALWAYS WILL BE -- or “IT”, for short.\n\nNow IT was and is both NOTHING and EVERYTHING at the same time. IT was NOTHING because in the Beginning, there were no things--only IT. However, IT was also simultaneously EVERYTHING because IT could be, would be, and always is every thing and all things that can ever exist. IT is infinite CREATIVE POWER with the potential to create anything, to BE anything. But at the beginning, as yet no-thing was created and there was only IT.\n\nAnd because there is only IT, anything that IT should create, IT would have to create it out of ITself. There was-is nothing else to create anything out of. There is not and cannot be that which is not IT. There is only the ONE.\n\nIT is far, far beyond human comprehension and anything we humans say about IT is less than a grain of sand on the Sahara. To even talk about IT, we have to use a comparison, an analogy, of something already within our experience=knowledge. Let’s start with a desert. \nImagine an infinite desert, an infinite plane of pure sand, with absolutely nothing else existing. Our desert is absolutely level without the least depression or the smallest mound. IT is exactly the same everywhere; there is absolutely no distinction, no differentiation, no distinguishing mark, and no landmarks. Even the grains of sand are identical. There is only IT. Infinite in all directions, IT has no limit, no edge--and therefore no center. Or everywhere is the center, depending on how you want to look at it. \n\nNotice that you have absolutely no way of knowing where you are on this plane. There is absolutely no reference point, no center, no edge, no distinctive feature, no landmark to distinguish any point from any other point. There is no relation or relationship—no Relativity--to anything else because there is no-thing else. Without Relativity, you can have no Identity. (The concepts of Relativity and Identity are explained in subsequent chapters.)\n\nIt makes no difference where you are on this plane—there are no differences, remember--because everywhere you are, IT is exactly the same. And no matter how you move or where you go, you are always exactly at the center of an infinity of sameness. Thus, there isn’t any place different to go—everything is the same. Nor can you go anywhere because no matter how you move you are always at the center of an infinity of NOTHING. Without Relativity to some point, to some distinction or landmark, you couldn´t even tell if you are moving or not. Therefore, there is no motion. \n\nPicture all this before you continue.\n\nNow let’s upgrade our analogy to three dimensions. The word and concept that we humans have that most closely corresponds to IT is “ENERGY”. IT is ENERGY with the characteristics of CONSCIOUSNESS, INTELLIGENCE, WILL and CAUSE=CREATOR. \n\nThe highest form of physical energy that we humans can perceive is light. Let’s use light for our analogy and move from two to three dimensions. So now imagine IT as light, as a glowing white fog. Imagine this lighted fog as infinite in all directions with no end, no edge and therefore no center--or everywhere is the center, depending on how you want to look at it. \n\nImagine every part of our fog=IT as exactly the same; there is no variation, no thinning, no concentration, and no differentiation of any kind. There is no distinction, no distinguishing mark, no things, no objects, no waves. There is no gravity or any other force by which to know an orientation or a direction. There is no up-down, left-right, in-out, above-below, north-south, etc.\n\nOur Light-Energy is CONSCIOUSNESS: Consciousness is the awareness, the experience of, existence.

the universe is constantly expanding although the rate is slowing and never reaches zero.\nexperts believe that the universe is finite yet has no edge, just like the surface area of a sphere. this could imply that if u reached one 'end' of the universe, u would end up on the opposite side or something like that

Well you can never be sure, but one theory is "The Big Bang".  Some useful websites are: \n\n- liftoff.msfc.nasa.gov/academy/universe/b_bang.html\n- www.umich.edu/~gs265/bigbang.htm\n- en.wikipedia.org/wiki/Big_Bang \n\nHave fun!

I hate to be the philosopher but that is why the question still reamins. No one can accuratly tell what lies beyond the boundries of the universe. Is there another? Is it just white noise? I believe that space is infinite and our "universe" could well be a part of a cluster of "multiverses". i was once told that the universe is expanding in the same way that a balloon is blown up. So what lies beyond our universe? I say space, space, and more space! \n\nIf our universe began with the "big bang" then that would mean that at some point the universe had collapsed upon itself, leaving empty space.

Gremlin I have contemplated this question for many years. The conclusion I have come to is this. For the Universe to exist today one of two things that we deem to be impossible has to have happened. Either something materialized from nothing, or something always was. At that point that we call "the beginning" one of those two things was fact. Which one, we may never know. So for me, "In the beginning God created" is as good an explanation as any. It cannot be proved or disproved. Perhaps it may be stated that in the beginning God said "BANG!!!". Perhaps God's previous job was just being an idea. Perhaps it was being the Idea (logos). Then the idea exploded into being, and God said "BANG".

I think that the big bang theory is flawed. It was theorized and believed by humans who just refuse to fathom infinity. Its based on the premise that everything has a beginning and an end. Greater enlightenment points to every ending is a new beginning. I think you're right, the little bangs theory makes more sense. And I will take it one step further, that these little bangs are the other black holes (assuming there are two kinds) where matter comes from another place not in this universe, a negative image of this universe. And everything in this universe is headed towards one of these (as yet undiscovered) black holes to be pushed out (bang) into the alter universe.
