What exactly is beyond the known Universe?

this problably sounds really strange. But have you ever thought that if you travel really faar enought out at space, you end at the same place again, at the end. (Like our own earth, if we goes around).
Wonder if there is something over the space, there again... wonder what that can be??..

I've recently being reading this book: The Curious Incident of the Dog in the Night Time.
Its a brilliant book, and in it their is some theories of the universe, I thought I'd post it here.

The main character believes the world will end, when the stars bounce back at us. So its one bright, heated, clustred impact of light slowly zooming towards the Earth.

And Aliens could be anything, I imagine they would be made out of a substance not known to man, and their ships and stuff made out of an unknown material. Or maybe their little bits of information flying about, that we created and sent off to another planet. After years and years we forget about the things that we sent off, and after more billions and billions of centurys, they visit our planet. And to us they're pure life-forms. Who have created their own civilization and what-not.

Thats my theory. 'twas a bit random, yes. But... meh.

That is my theory exactly. I think that would make a lot of sense, too!

Then there wouldn't be any begining, or end. You could appear to go on forever because you would have no idea where you are!

I think we have something.....

Quick! Call the scientists!

I kind of believe it to be like this;
The universe is like a box, but has actually no faces, mabye more of a straight line, but the "sides" are what are important. The sides have a non-existant mirror that has a reflection of our own universe. Nothing can go past there, for it will be destroyed. In the reflection is the parallel universes, reversed to have oposite, well, everything (thus, a mirror). Although we'll never see it, because the universe expands faster than time, and is thus conseved as "infinent". There is nothing imbetween the universes, due to nothing is something, and thus non-existant. These veiws may be too philosiphic to be fact (even though our theories are mear shots-in-the-dark) but, these are my ideas.

To sum it all up, We are on the other side.

The parrallel universes aren't mirror images, though. They are all different to one another. They aren't parrallel universes at all, they are co-existing realities. The first four dimensions are length, breadth, depth and time. They are what control the universe and everything in it. (However, the universe rapidly expands over time, so length, breadth and depth do not apply to the universe itself.) The fifth is co-existing realities. Beings that share the same space but are unaware of eachother's existence. It would be like me typing up this post, and a 12 year old girl named Kerry, for example, could be writing it as well. There could be a backwards reality, where just as I'm typing this now, someone else is un-typing it, un-posting it, un-posting other posts, then going backwards into bed at 5:00 in the morning, and waking up at 12:00 in the morning to Jack Johnon singing Cookie jar on a CD playing backwards. There may be another universe where I am, in fact, dead, and when I die, will be born again. But there are no parrallel universes, or anything else, outside our universe, because it is always expanding, and it needs something to expand into.

There was a theory I read that I believe. The theory is called the soccer-ball theory (I think). It explains that the universe is like a soccer ball with the little shapes around the ball leading to another point that sends you back to the same point. It was kind of wierd and I don't know if I am explaining it properly.

The simplest way I could put it is that say if a ship was sent of from earth going in one direction, a straight path with out turning or maneuvering anywhere, the ship will eventually end up returning to earth from the opposition direction it came from. This is of course impossible to prove now because it might take a millenium to go same many light years away from earth to end up at earth again from another direction and we don't have that kind of fuel to keep ship going for years.

Remember the old Super Mario game on nintendo? There was a level where you could go through tunnels and end up and the same place from another tunnel. This also happens in the game pac-man.

A more accurate one was in "The Matrix: Revolutions" movie where Neo was trapped in a subway and tried to get out by running one direction of the train tracks and returning at the same point. The only way he could get out was getting on the train that stopped in the tracks where he was trapped.

On a regular soccer ball there are black shapes around the ball, And the ball is used to describe the universe the only way you could end up on another path, direction, "dimension", or parallel universe is if you go to the direction of one of the black shapes which act as a mirror to your current origin, If you take the path of white shapes you will eventually go nowhere to return back to the spot where you came from. So there is not really an end or edge to the universe, it's either you go nowhere or to mirror of the same universe you reside in with slight changes. (i.e. you return to earth finding another "you")

I always find that mind boggling since the universe is so big. Many people do not believe in that theory because they think the universe has NO shape so a soccer ball can't be used to explain it.

Beyond the universe is more world, i.e. the rest of the multiverse. Some with different historys others with no earths, some with out a recognizible laws of physics. The question is can we get out of this one. Einstien physics says the universe is curved, so if you travel in any direction not matter how far you go you end up back here. Maybe blackholes and wormholes can get us out but who knows. The current idea of the universe ending is that everything gets sucked into blackholes they disspate due to hawking radiation and then once again there should be nothing. Stop imagining that black or white space I said nothing!

The universe was created by high temperatures in the early stages of the Big Bang. After being exposed to constant heat, the plasma (which is now the center of the universe) exploded violently, infinetly expanding over the universe. However, plasma is not constant so it created pockets of varying tempuratures throughout the universe. The tempuratures formed and molded debris into matter. The matter formed a sense of gravity and form in the universe.


The momentum of the Big Bang is still pushing outward, feeding on the matter it leaves behind. It will infinetly expand as long as matter is being formed.


In the known universe there is not just nothing, there is sporadic amounts of hydrogen scattered around. Outside the universe lies matter dubbed dark matter or black matter. It is in a complete vaccuous space and contains no types of matter as the expanding plasma has not changed the tempurature (which in turn forms matter and the hydrogen that is in the universe today).


Hope that answered your question!

Source?

A blackhole is simply matter that has been 'super compacted', and has no special properties.

The current idea of the universe ending is that everything gets sucked into blackholes they dissipate due to hawking radiation and then once again there should be nothing. Stop imagining that black or white space I said nothing!

No, the current idea has entropy causing all the energy in the universe to be spread out equally, thus leaving the universe with euqual amounts of energy spread accross all of it, until all the particles in it decay, leaving it even more empty then it was before.

And because of that the mass cause an huge disturbance in the curve of space time. From wich no matter or energy (with the exceptance of hawking radiation) can escape. To demonstare this place a bowling ball on a strong sheet or something and get a couple of people to lift it off the ground. Notice how the bowling ball cause the sheet to curve. The same thing happens to space time around any object of mass. Now imagine that bowling ball was the same mass but the size of a marble. It would tear a hole through the sheet. This is what a blackholes mass does to space time due to its density. That and the fact currently we haven't been able to apply known laws of physics to a black hole, even in theory, with out having them break down into a mess of mathematical gobbled gook suggest we need to know more about the things and rethink the theory before we say out right that it has no special properties.

actually, black holes do follow the laws of physics. the easiest way to think of it is a point with infinite pull. everything that's sucked into it is compressed infinitely small. it's not some passage into another realm. in fact, from what I understand, time actually stops inside black holes. kinda strange to think about...

Okay, in contradiction to my original post, there may be other universes out there, but they must be pretty far away. You could travel a vingtillion (a million to the power of forty-something, just so you know...) miles away, and you still couldn't get there. There must be a point where they meet, causing a Big Crunch, in which the Universe starts to contract back into a singularity. As it crunches, all dimensions governing it contract and run backwards with it. So time runs backwards as well. So, of course, we will run the other way once the Universe is about to end, if our race lives that long (which I doubt). Once it becomes a singularity, it will cause a Big Bang once again, and a completely new universe will be born, expanding until it can't anymore. But even then, how can they be the same universe? All universes are born at different times, and if they always change with each Big Bang, there can be no parrallel universes, as I said before. But I still think that there are co-existing realities as well, as I also said. Satisfied? Oh, well, suit yourself then...

Actually, Black holes to not transfer you into another realm. Black Holes were mathematically supposed to be connected to a White Hole somewhere else i the universe, but it can't happen. By travelling through it, it would collapse in on itself. Even if somehow u made it through, u would be fried up by X-Rays and Gamma Rays that the Black hole has sucked up from nearby stars and cosmos. Wormholes are truly fictional and will not exist, it's just cool to think about them if they did. Black holes do not suck up everything, they only suck up the objects that pass their horizon, which is the point which light cannot escape. If you were hoping to be sent to another galaxy by jumping into the Black Hole, sorry, you would quickly be torn apart by the gravitational pull of the black hole in about 8 seconds after u passed the horizon, and thats on a big black hole. On a small black hole, u would be torn apart before even passing the horizon. Time does not stop in a black hole, it's just that light cannot escape so anything that happens beyond the horizon cannot be seen on the outside. It takes the light that didn't get past the horizon a long time to climb back out to spectators, but anything beyond the horizon will never be saw, unless it is an evaporating black hole. So no one will really ever see u die in it.

Cucco_man, perhaps you misread:

we said the same thing...sorry if I was unclear.

Yea, i was just gonna say that time doesn't stop inside black holes, then i just spilled all my knowledge on them.

Sorry bout that,

I find the universe very interesting as well, i know that it is still expanding and is like 156 billion light years big right now and still expanding. If it is in fact finite, then we could get a Hall of Mirrors effect, which would be really cool.

no problem

the universe isn't infinite, but it's unbounded. this is always a hard concept to explain, and you need to drop anything you thought before. and don't try to picture it either...it's impossible.

the best analogy of the universe is the surface of a balloon. the surface area of the balloon can be measured - it is finite. but you can draw a line all the way around it, which is how it's unbounded. now, the surface area of the balloon is a curved 2-dimensional plane. the universe has more than 2 dimensions. so just trying to picture that same expansion but on a 3-dimensional plane is imind-boggling. but that's how the universe is.

edit: for the record, I read a bit more, and yes, time does stop in any black hole. as hawking says in one of his lectures, "At a singularity, all the laws of physics would have broken down." this includes time, matter, and just about everything. in fact, the big bang is often described as the reverse of this.

This is how I picture the universe.

Imagine a glass if you put water in it it gets filled.But if you break the bottom of the glass it will never get full because when you broke the bottom of the glass you changed the capacity but this new capacity can never be filled because it has no boundarys to hold the water this makes the capacity infinate.

Well, I think that if there are quadrillions of galaxies, there's probably quadrillions of Universes too, and also there is no solid proof that there was a big bang in the first place.

Time is looping, I've decided, and there is a 1 in a 10,000,000,000,000 chance in everything, for example, the way you brush your teeth in the morning, 0.0786 seconds each brush? Or 0.0847 seconds each brush? Which word I will type after the 132nd one, should? Gardener? Flourescent? Or perhaps I won't continue at all, maybe I'll have a heart attack?

So time is looping every, let's say, every 100 Billion years, and the number of these chances are something like 100, followed by 20 billion zeros, it could have looped 5, 316, or even a billion times already, and every period is outlandishly different to the last.

And so, there may be 500 quadrillion different time zones, each one surrounded by a tide of thrashing time, that could turn a piece of dust into a Universe in it's own within milliseconds, it is impossible to travel between these time zones, naturally, and one of them could be looping right now, and now, and now, due to the huge number of them.

So, er, yeah.

I'm positive that I've said this before, but what the heck.

It has been confirmed that th universe is expanding, as such, right now, it's bigger then it was 10 minutes ago, an hour ago it was even smaller, 10 years ago it was smaller still, until we reach the point that several hundred billion years ago it was the size of the head of a pin, we can keep going back forever, but there isn't any point.
So, we have this super-dense universe, but in order for it to start expanding it would need massive amounts of energy, when it gets this energy it starts to expand, this is what we call the big bang.

Time is looping, I've decided, and there is a 1 in a 10,000,000,000,000 chance in everything

If I flip a coin I have a 50% chance either way of it being heads or tails.

So time is looping every, let's say, every 100 Billion years, and the number of these chances are something like 100, followed by 20 billion zeros, it could have looped 5, 316, or even a billion times already, and every period is outlandishly different to the last.

do you have any proof what so ever? Any sign that time has or is getting ready to loop?

And so, there may be 500 quadrillion different time zones, each one surrounded by a tide of thrashing time, that could turn a piece of dust into a Universe in it's own within milliseconds, it is impossible to travel between these time zones, naturally, and one of them could be looping right now, and now, and now, due to the huge number of them.

This really confuses me, Time isn't a force, it can't destroy anything, and even if it could where do you get this idea about multiple 'time zones' with deadly time in between them? Again, any evidence? If particles could move between these and get destroyed we should notice a decrease in the expected amount of matter in the universe, and as such, the rate at which it is expanding, as current tests show that there is more matter then can be accounted for your idea just doesn't hold up.
