I would like your opinion on this question. . .?

Question

If scientists have stated that the universe is everything and also that the universe is expanding, if the universe is everything what is it expanding in? (please let me have at least more than 3 people)

Answer 1

If the universe is everything, then what is it expanding into?

Before we can address that question, we must first define universe.

The word universe denotes all space and everything (matter, energy) contained within it. The prefix uni means one. The root verse means word, carnate message, meaningful substance, matter. Questions regarding our universe persist today. Does it have a beginning and end, or does it go on forever and ever? Is it linear or curved? If it has limits of length or curvature, then what lies beyond the Universe? If something lies beyond the Universe, then can’t we accurately call that the Universe?

Some lay people and some scientists conceive of the universe as infinite space. Others define the universe as finite, or limited (perhaps curved), space. Still others incorporate the elements of matter and/or energy into their definition of the universe, as opposed to the space beyond matter and energy.

Given these concepts of our universe, some scientists conclude that the “totality of space could be infinite. Shrink an infinite space by an arbitrary amount, and it is still infinite. (Scientific American March 2005).”

As to the notion that we live in an ever expanding universe, moving away from every other universe on the fabric of space-time, some scientists are careful to point out that “

Andromeda, our nearest large galactic neighbor, is actually moving toward us, not away. Such exceptions arise because Hubble's law describes only the average behavior of galaxies (Scientific American March 2005).”

In accordance with your supposition that our universe is in another universe, “it has been hypothesized by some scientists that the universe may be part of a system of many other universes, known as the multiverse (http://en.wikipedia.org/wiki/Universe).” Modern astrophysicists talk about multiple "pocket" universes that branch off from one another. Stephen Hawking points out that parallel pocket universes can have no effect on a real observer inside a single pocket, so, according to Hawking, they are theoretical baggage that should be eliminated from cosmology, the study of the origins of the universe.

Some string theories define the universe as a three-dimensional space in an invisible space having more dimensions. This is, in essence, a universe within a universe. Our zone, a “braneworld” could periodically bounce into another parallel braneworld. This may create what would appear as a Big Bang from one perspective or a Big Bounce of alternating expanding and contracting universe from another perspective. Such a cataclysmic event is thought to occur 300 billion years from now, resulting in the rearranging and creation of a new universe.

If the universe is everything, then what is it expanding into? It seems that our universe is all matter, space, and energy that we can perceive in this closed system. However, that does not mean that there is not additional matter, space, and energy outside our universe. In other words, there are probably other universes. Therefore, the zone that we call our universe (or braneworld) may be moving through or expanding into other universes (or braneworlds). In sum, all universes may be moving through a multiverse.

Answer 2

That is a philosophy the scientists made, of their own opinion. Something that its not fully explored and well known how can it be expanding??? Well only if they have been in their previous life or God has told them. That is impossible to know and even estimate. The thing they probably wanted to say is that, with the better the technology they have, the more will be discovered. For example, at the beginning they found only one by one of the nine planets in our solar system, and look how they expanded their knowledge. I think that's what they meant. "our knowledge for the universe expands more and more". :)

Answer 3

You have to look at it like this: all of space and time exists within the Universe, the Universe does not exist within space and time. Therefore, the only answer is nothing.

But, that answer conjus a lot of problems, because we can't quite wrap our head around nothing. You might ask, what if I were standing at the edge of the Universe, and were looking at this Nothing: what would it look like? Two answers, if that could happen, if would like like "nothing." But, that is probably not possible, because most likely the Universe doesn't have an "edge" much like the Earth doesn't have an edge.

How is that possible? If you were to travel in a straight line forever in the Universe, you would most likely end up right back where you started, just like if you were to travel in a straight line around the Earth. The Earth's surface, which is 2-D, is curved in the 3rd Dimension. It is likely the Universe, which is 3-D, is curved 4th dimensionally, which is how that would be possible.

But, back to the question: science cannot truly answer it. Sorry ;0)

Answer 4

The simple answer is nothing, but that doesn't do much for you, right? Think about it like this, what would separate "our space" from that which we are expanding into? Plus, the fact that we are inside of our universe makes it tough to try and define what is outside of it, especially with the universe being so big and we cannot find any boundaries or edges.

Answer 5

At this point in our scientific knowledge there's no way to answer your question. Lots of ideas and theories, but not a single shred of hard, scientific evidence to validate them. The universe is everything there ever was, is now, or ever will be. Asking "what" the universe is expanding into is like standing at the North Pole and asking what's farther north.

Answer 6

Well, it's not really expanding in anything, as the universe has no edges. Think of it instead as if the universe is spread around the surface of a ball, and then becoming increasingly more dense.

Answer 7

Well obviously the Universe is everything because that's where everything is. So to answer you question the Universe is obviously expanding into a bigger universe, that is and has everything. you answer you own question if you look at your question.

Answer 8

No one really knows. For all we know the universe isn't the infinite tea cup. There could be other things outside the universe. Maybe you should ask this question in about two more million years..We might have the answer by then.

Answer 9

How do they know it's expanding if nobody has ever been to the end of the universe?

Answer 10

I think they're referring to the known matter in the universe. By measureing the doppler shift of the light from other stars, and galaxies, they've determined that most observed matter is moving outwards.-- Think of the universe as a lump of raisin bread dough. As you bake the dough, it expands, the raisins (representing galaxies) spread, becoming more distant.
