But the space between objects in the universe is expanding too. They're not all just moving in an "outward" direction from some central point.

Space is expanding in all directions.

My thought is, what does this theory solve better than current ones? if it doesn’t address something current theories can’t explain about the observational data, then it’s just a good idea for hanging around smokin dope.

that said, nothing wrong with hangin out, smokin dope, and wondering about the universe.

"The edge of the universe" should be rightly called "the edge of the observable universe".

Stars, planets etc are not less dense than the average sphere of space. You can't compare individual objects with an entire system to the entire system itself.

Objects less dense than water float in water because all matter in that system is under the effects of the gravity of earth. So they are placing themselves in a stratified hierarchy wrt the distant gravitational force on them.

Is there anything, besides a thought you had, that leads you to believe this theory might be true?

Do you think we're at the center of the universe? Because rejecting that idea is an important part of modern cosmology.

If the universe as a whole is not expanding, why does it look like everything is moving away from us, specifically, as if we are at the center? Also, what edge? We don't think there is an edge of the universe, so what makes you think there is?

Out to the edge in front of us…then swooshed around the outside and eventually back into the middle. We just can’t see if from our 3d perspective

A problem with your hypothesis is that, in diffusion, as the matter becomes less dense, the rate of expansion slows. In the universe, the rate of expansion is increasing. Also, as someone else mentioned, from our perspective everything is expanding in all directions at an increasing rate. In a diffusion system, you can easily observe diffusion rate and concentration gradients.

It's better explained with the example of surface of a balloon with dots expanding also distance between the dots is expanding. Perhaps it's just too many dimensions for us to comprehend.

This is not true. Only very distant objects expand at away from us at apparent faster than light speeds. Nothing is moving faster than light in its own reference frame. The speed of light is\ 73 kilometers per second per megaparsec. That means its only the effects of the change in distance that appears to be faster than light could travel. In essence, the objects are receding away from us at speeds exceeding the distance light could cross for the same unit of time.

This is because each "point" in space is expanding at the rate above. The more "points" in space you have between you and a distant object, the faster it expands.

If there are two megaparsecs between you and an object, it will appear to recede at 146 km/s/mpc.

​

Works out to about 4100 mpc between you and object to exceed c.
