Its being said that the universe extends to several million light years... Whats there beyond that? I mean after that there should be something... Its being heard that there is some kind of gases and all! Whats there beyond that???

ur question is "what is at the end of the universe"but does it really have an end because if the big bang theory is correct then then when the whole universe was one atom or very small what did it expand into because if there was nothing there it couldnt have expanded. for example if you have a room and you say that the walls are the end of the universe then you build on to the room to make it bigger (the universe expanding) there has to be room on the other side of the wall for you to build into.

There is nothing called the end of the Universe. There are three possibilities of the shape of the Universe.

First, the Universe might have what we call positive curvature like a sphere. In this case, the Universe is called "closed" and it has a finite size but without a boundary, just like a baloon. In a closed Universe, you could, in principle, fly a spaceship far enough in one direction and get back to where you started from.

The second possibility is that the Universe is flat. This kind of Universe can be imagined by cutting out a piece of a baloon material and stretching it with your hands. The surface of the material is flat and not curved. You can expand and contract it by tugging on either end. Flat Universes are infinite in extent and have no boundaries.

Finally, the Universe might be "open" or have negative curvature. Such Universes are also infinite in spatial extent and have no boundaries.

Thus whatever be the shape of the Universe, there is nothing called a boundary and hence nothing called the edge or end of the Universe.

space exists only IN the Universe and there is no meaning to the term "outside the Universe". What happens in expansion is that the space itself is expanding. Thus, when we talk of galaxies receding from us due to the expanion, it is not that the galaxies are moving, but the space in between us and the galaxies is expanding.

every region of the universe, every distance between every pair of galaxies, is being "stretched", but the overall size of the universe was infinitely big to begin with and continues to remain infinitely big as time goes on, so the universe's size doesn't change, and therefore it doesn't expand into anything. If, on the other hand, the universe has a finite size, then it may be legitimate to claim that there is something "outside of the universe" that the universe is expanding into. However, because we are, by definition, stuck within the space that makes up our universe and have no way to observe anything outside of it, this ceases to be a question that can be answered scientifically. So the answer in that case is that we really don't know what, if anything, the universe is expanding into.

or if it's really expanding.
who knows we might never know the answer to this question

The universe, if it means the galalactic matter alone is in space and it is void - emptiness that is beyond and around everything that is matter , Matter has shape and boundary. But space - emptiness - "ntothing " has n0o shape and no boundary- but this emptiness contains everything in the Universe.Nothing can exist or move without this emptiness . So it is space ha is beyind everuything - including the universe . Universe will have shape and boundary as it is made up of matter and space has no boundary and is able o hold everything as it is boundless and immeasurable and infinity.,because it is "NOTHING " It is simply inconceivable . If thre is something - SOMETHING - there will always be something beyond it and something else beyond tha something and so on endlessly . only nothnginess can hav ethe charcter of absolutism and finality without character and end or direction or circumscription.There is no question of anything being beyond it .This may be difficult to conceive for the human brain that is used to a controlled and closed environment on the earth subject to the effects of gravitational forces.An environment totally different from the one that is prevailing on this earth is not used to us and not experienced by us and so it might gbe something strage to conceive of something that has no boundary.
The Astronomers say tha that he space also came out of he Big Bang . It mens haha the space was wihing the primodial mater and tha space was contained in the matter.This idea is s9omly wrong for he simple reason tha follows. even if he primordial matter were a microscopic atom , it should have existed in space only as it should have had a volume however microscopically small it might have been. If it had no volume , hen it could not have been exised . Everything for its existence needs at least some space to the minimum of its most compressible volume. It tha much of spcase had no been here , the matter could not have existed at all. .So space is "sine qua non" for the existence of everyhing that is matter . Matter must necessarily have shape and boundary and its boundary would naturally be cicumscriped by the empty space only.So beyond everything and beyond the boundary of everything there is spce and space alone comprises everything and everything exists in space alone . Space alone needs nothing to exist in. That is its singularity.

You can consider the entire universe as an expanding soap bubble in water. Its a kind of vacuum in space-time and created out of nothing.

But the creation of the universe shall also have resulted in the birth of another universe filled-up with antimatter. When these two collide, all energy shall be emitted in the form of light.

Coming to your point - what is beyond the universe. The answer is vacuum - meaning nothing.

The entire universe was created out of nothing, and it is going to be nothing at the end. However, the very basic principle is that "dynamism" shall always be maintained in one form or the other. That is, there shall be some kind of "local oscillations" in the vacuum, which shall contribute to the birth of another universe or, star.

But why these "local oscillations"? The basis is that there is only one "fundamental force" - but that can not reference anything - including itself (like without positive there shall be no meaning to negative). In order to make a reference, it manipulates itself so that some reference is obtained. In that process, the opposite field is created - paving way for the creation of the universe.

You can also go through some of the literature of Stephen Hawkins.

More universes. Do you really think that if you made a toy that you would not continue making other toys, especially if you enjoy it? What you really call the "end of the universe" is that the elements which made what we call universe are not there at the end of that universe, right? Thus, the constitution of this outside-our-universe is made up of elements that are different that what the universe we live in is made of. Thus, that difference is hard for us to recognise. Every action has an equal opposite reaction... the other universe is growing smaller while ours is becoming larger.

The universe is FINITE but WITHOUT BOUNDARIES.
It's sorta like wrapped around.NO EDGES.Remember the videogames of the 80ies such as Pac-Man where you would re-appear on the left of the screen when you disappeared on the right? It's somewhat similar in reality but in all directions(and 3-dimensional space).Should you travel for 15 billion years at lightspeed you'd occupy the same position you started from again.
Now this is more tricky.When we say the universe is expanding it is not matter that travels further appart through a fixed space-time but rather the FABRIC of SPACE-TIME itself that expands.Imagine a 2D space unfolded in a 3D space as a balloon.Matter would only exist on the fabric of the balloon itself.Nothing exists inside or outside of the balloon.Imagine dots on the balloon.Now you inflate the balloon further.All dots appear to drift appart from each other and from the point of view of one point all the other points always seem to drift appart.That's what is actually observed when looking at galaxies but this is a 3D space and to visualize it we'd need 4D to unfold the 3rd one.

Well,


Many theories have been provided for the ideal "end of the universe theory". During the late 1960's when many astronomers were persuaded that the Big Bang scenario was the best explanation of the universe's origins. There are two obvious fates emerged as contenders: The expansion will continue forever or the expansion will eventually be halted by the universe's overall mass, and collapse will ensure, culminating in the Big Crunch. In the 1980's inflationary theories predicted a third alternative: a flat universe in which the outrush will slow to a equalibrium with a final destiny being either endless expansion nor collapse. In recent years the pendulum has began swinging more in the direction of the open universe. But to keep ourselves in neutral territory for a moment, lets flesh out the skeletal ideas of three scenarios of the universe's ultimate end.

A closed universe is clear cut. A few tens of billions of years after the Sun becomes a white dwarf, the expansion will cease. Like a movie running in reverse, the galaxies begin to approach one another, first gently, then with escalating violence as they merge into a fierce fireball of supernovas and superquasars. Nothing can prevent total callapse in such a conflagaration, and the entire affair will swallow itself into a black hole the mass of the universe. All that we know today will be compressed into a singularity, smaller that a nucleus of an atom. Time and space will no longer exist. :cry:

Some cosmologists have sidestepped the finality of the closed universe by suggesting that the collapse of our universe will provide energy for a the creation of another. Our universe then becomes one bead in an infinitely long string of birth, death and rebirth. The oscillating universe hypothesis has greatappeals because it embodies a dynamic, evolving universe with a definite life span. Yet it never dies; instead, it reincarnates, phoenixlike, from it's own ashes. But in recent years, certain theoretical difficulties have claouded the oscillating universe idea. Despite efforts by numerous cosmologists, no one has offered a convincing reason why the collapse will not be the final curtain of the universe.





The final end


Less tidy than the life cycle of the closed universe is the final blackness that awaits both the flat and open scenarios. Neither has definite end; the universe just fades away. Galaxies will continue to manufacture stars from the dust of gas within them for at least another 10 to 20 billion years. But after that, when nebula gas is depleted and new stars thatwill continue to shine are the least massive red dwarfs like Proxima Centuari. If Earth escapes being vaporised during the Sun's red giant phase, the sky of this distant future will be as black as the inside of a cave, at least to the naked eye. In that long night of the future, perhapes 40 billion years from now, the corpse of the Sun will cool from a white dwarf to a dark, dense lump a black dwarf being undetectible exept it's gravity, which will continue to hold Earth's orbit. Red dwarfs stars with masses from one-quarter to one-tenth that of the Sun will continue to shine for another few trillion years since they cook their fuel slowly.


Star evolution

Sun burn long and slow, some lasting more than 10 trillion years before finally sputtering out. But by 100 trillion years from now, the last stars will have winked out. The universe containing the darkened and collaped corpses of a trillion trillion once brilliant Suns, will finally fade to black. Almost all matter in this distant future universe will be locked in stellar tombstones: black holes, neutron stars and black dwarfs. The remainder will be in the form of planets, asteroids and comets. If current predictions in subatomic physics physics are correct, most of the universe's protons will have decayed by 100 trillion trillion trillion trillion years from now, causing everything but black holes to decompose. Only the black holes will remain, leaving the universe as a desolate void punctuated with invisible gravity whirlpools.

A solar-mass black hole would take a million billion trillion trillion trillion trillion trillion years to snuf itself out. More massive black holes will take longer, but eventually the universe will become an exceedingly tenous mist of subatomic particles and radiation for closer to a vacuum than intergalactic space is today. In this bleak future the tempurature everywhere would be less than one-trillionth of a degree above absolute zero.

The Universe is Infinitely and eternally.
1. Everyone knows, that absolute temperature T=0K cannot be reached.
We can only indefinitely come nearer to her.
2. Everyone knows, that nobody can reach
absolute speed of quantum of light c=1.
We can only indefinitely come nearer to her.
3. But everyone also knows, that only quantum of light goes with
absolute speed c=1.
It is the fact, it is a reality.
Question: Unless can this absolute movement c=1 occur in relative reference frame ?
Answer: No.!
The absolute movement can occur only in absolute frame of reference.
But only one absolute frame of reference is known T=0K
(which is impossible to reach).
And only in her quantum of light can move with the absolute speed c=1.
And it is also reality.
So, what can tell quantum of light about his travel in the Infinity, parallel world?

The universe is "ever" expanding in all directions.
The basic physics of the universe is that you can never get to the edge of universe, because no matter where you are... you are always at the center of it. This center apply to every object in the universe...

or

There is no "edge" or "center" of the universe.
(but I like the first one better.... it makes you feel important)

More universe? More space? That is as far as we are able to see. Perhaps we will know one day...when traveling billions of light years isn't a problem.
