Where Does Space Come From and What Theories Explore Its Origin?

[36grit]

Where does space come from? In an expanding universe this conduit must be generated by something. Are there any theories?

Is it possible that the universe is not expanding, but that we are shrinking, or is it a matter of perspactive and dimension?

Just because something is expanding, doesn't mean that we need "more" of it. Think of blowing up a balloon - the balloon expands without needing more rubber.

Is there any scientific evidence of this stretching?
Are there any other theories?

Your balloon model works well in a 2 dimensional world but if we look at it in a three dimensional setting , say a spongey material, we see that the space outside the sponge is simply sucked into fill the voids. So how can space suck in space to fill the void without it coming from somewhere ?

There is a plethora of evidence available for the metric expansion of space. A simple google search should bring up a sufficient number of results.

I'm not entirely sure what you mean by "other theories". Could you perhaps expand a little?

If the space in our universe is suking in space from outside our universe then what's the difference? If the space is being sucked in by another dimension, Let's say time, then some entity must define the point of entry. And now we're back to my theory "Jet Theory", that is unacceptable on these forums so I was looking for what is acceptedable in the scientific community.

I'm afraid I really don't understand what you're getting at. The balloon was intended as a simply analogy and shouldn't be taken literally.

The commonly accepted notion of the metric expansion of space is not to consider space as expending into something else which already exists, but rather simply expanding. Rather than thinking of "space" expanding, think of it as the distance between objects increasing.

perpetual motion?

 

[Hootenanny]

perpetual motion?

Pardon?

 

[36grit]

Pardon?

I ment perpetual distance.

I guess that's the acceptable scientific theory.

Truly I hope there's another one.

What is it you don't like about the current theory on the expansion of the universe? I think you should probably attempt to understand it better before you dismiss it.
I don't think we can understand the expansion of space the same way as we can understand the expansion of "stuff" (matter) because space is essentially a measurement. I don't know that many of us quite have our minds around what it means for the universe to expand, and how it can do it faster than c. If you're going to dismiss a theory you should probably have some understanding of it first.

Now picture a balloon with 3-dimensional hypersurface being inflated in 4-space. You still only have stretching. The "inside" isn't part of space.

I think the term "perpetual distance" defines a pretty good understanding of the theory.
I never dismissed it. I just would like to see some others to compare it to. As far as I know, at this point, there only two theories. It seems the one dismissed is the only one that gives a reasonable explanation.
