If the universe is always expanding. What is it expanding into?

Void. Just because you can't concieve void doesn't mean it isn't truth. There are many inconcievable things that are present in this reality.
EDIT: But I am no scientist so I cannot explain how this works.

It's expanding into itself. The universe, by definition, is everything. So, once you pass the oldest stars and objects, you get into empty space which is still Є the universe (please, bear with the symbol; it was the best I could find).
So, when someone says that the universe is expanding, they're actually just talking about all the matter that is pushing further and further into the universe. That's just a theory, food for thought, if you will. I don't, nor does anyone of whom I know, necessarily believe this. --Guido http://andy.mikee385.com |

But where does all that matter that is constantly expanding go?
Where did the space onto which it is expanding to come from in the first place? And what if it is a finite space and it will eventually just stop? I think that the universe is just still going from the explosion of the Big Bang and that it hasn't even come across the point where it is anywheres near when it will stop. I hope that makes as much sense to you guys as it did to me

It's hard to concieve that the universe has been around forever. And it's hard to concieve that God exists. It's hard to concieve that it expands into void. Something has to be assumed. Humans can't concieve forever in the future, or forever into the past. These are things we cannot explain? But what are you going to do about it... AS for your thoughts on the fact that the universe is still going: Please go research a little. WELCOME TO THE INFORMATION AGE! WHERE YOU CAN LEARN ANYTHING IN AN HOUR!

Actually, one highly technical way to think of the universe expanding is this: the matter of the universe is not expanding; space itself is stretching. Void is becoming bigger because the fabric itself is expanding over time.

Another note... tasuke brought up expanding matter. I think EVERYONE can clearly say that matter is neither created nor destroyed. So, no new matter is being created in our universe.
What is happening is that the solar systems and galaxies that are the furthest apart are continuing to move farther apart from each other. So the galaxies are getting farther and farther apart, meaning there is now more empty space between them, and obviously, less empty void on the outskirts. It is unknown if the outskirts extend infinitely. There was another topic similar to this, in which i recommended a book for anyone interested in the expanding universe and big bang theory. I'll give it again: Faster than the speed of light by Joao Magueijo.

So technicly the Universe isn't "Creating, or Destroying" matter, according to the Law of Conservations... So it is just stretching the bonds? 0.o Just a thought?
Which also bring in to the question, What is black mater? This "Fabric" that the Universe is stretching to advance farther into the way? Anyways, Hello there, My first post. I gota go make a signiture and a avatar. -.-' -Alan

Questions about infinity are always tough to "answer," but I enjoy trying anyway.
As Drac said earlier, one of the theories I have heard is that "expanding" can be read as "stretching." For example, if one part of the universe stopped expanding (We'll use a human as an example) then that matter would "see" the rest of the universe expanding. However, since everything is expanding proportionally, it's not noticeable to our eyes. I'm not sure where to go from that, but I thought it was an interesting point to look at. There ARE many views on exactly what the universe is. For all we know, it may be a massive black hole that's part of a much larger mass. Just putting in my thoughts on the matter. |

I have wondered at times about the universe, but until some aliens like the Borg come along or something...I could really care less.

the universe itself is ran by God. it is only expanding in our knowledge. This question in and of itself is a technical mishap and a glitch to your mind. Believe it or not, God is real, and if you dont believe, then you arent ready for the consequences that will be readied for you later.

Religion has no say in this manner, please do not bring it into it.
I just heard something about this manner and completely forgot about it. Oh well, somebody else probably said it anyway. I just wanted to post the above line. ~Squeek |

I heard a scientist say once that the universe is stretching and that in millions of years it will just rip open unless the gaint guy clips his finger nail that our universe is on then we will die sooner. just a thought

Ok, apparentley most of the people here believe the universe is infinite. So how can the universe be expanding if it's already infinite? Infinite should mean that it's already taking up all the space there is to take up, so to say it's expanding means it's not infinite yet but it still has time to go. Like if you take a balloon and blow it up inside a bottle, once it's covered all the edges and sides it can't go any further, therefor it's taken up the maximum amount of space inside the bottle and only then is it infinite. So relate the bottle to the boundries of the universe, asuming there is, and the balloon to the universe. If it's still expanding then it's not infinite. That leaves two things to believe, either you can believe the universe has no boundries and is just simply never ending or the universe is expanding still and hasn't reached it's outer "walls". I personaly believe the first one.

This is where our views of the universe diverge. You're saying that the balloon represents all the matter that we can see, and that the bottle is the universe. The problem you're suggesting with the infinite expansionary universe is that when the balloon expands to the edges of the universe, it can't go anywhere from there, destroying either the infinite or inflationary adjective from the description of the universe. I say you have a problem of definition. The universe is actually everything that we can observe. All the galaxies, stars, gases, comets, etc. that we can see in some form or fasion make up our universe, since it is, by definition, our all-encompassing world. Therefore, there is no bottle from your example. Our universe (The universe) is represented by the balloon and the contents of the universe the contents of the balloon. As the balloon expands, the molecules become further and further apart (spare the physical PC business or just assume we're heating the balloon rather than blowing it up), and the size of the balloon has no limit. When physicists and astronomers say the universe is expanding, they're judging it relative to our position on Earth and relative to other celestial bodies (which are measured relative to Earth, to come back to that, but whatever). So, universal expansion is just the increase in distance between bodies. Well, if everything's getting further away from everything else, then the objects on the boundary of our universe must be getting further away from the center, ergo the universe is expanding. Now, if you want to postulate a physical barrier outside of the universe that is going to stop it like a brick wall, I can't argue with you, but you won't find many people willing to agree. --Guido http://andy.mikee385.com |

I said in my last sentence of the post that I believe the "first explanation", the one where I said the universe is never ending. So I don't believe in any "walls". Your suggestion that the things inside the universe like the planets and stars and galaxies are getting father apart is perfectly logical and I have no problem agreeing with it. That makes sense. I just don't believe the empty space is moving outwards like the air and hydrogen because as I said before I already believe it's never ending.

This is another good way to look at things.
Once people thought that the earth was just a flat plane, i think this is similar to what most people think about the universe. Now pretend you lived much later into the future, do you think we might discover that this universe is actually a sphere. This theory also answers the questions of the expanding universe idea, just like continents shift and over billions of years end up in different places, the expanding universe is just a swirling "expansion" of matter, where we are just revolving around something. You would consider people to be expanding correct, well they are just going around the circular area that is earth moving this way and that, eventually bumping into itself. What else is there to explain how the sun is kept in line with the rest of outer space, earth keeps people with it, the sun keeps the earth and other planets with it, and some core is probably keeping the sun with it. sound good? |
