So you think the Universe is Expanding, what if it is actually shrinking!

Try my this Unity powered Universe simulation that shows how an expanding Universe can look exactly the same as a shrinking Universe to an internal observer.

Had the idea that the Universe could be shrinking, checked online and found that there has been at least one scientific paper that postulates that a shrinking Universe look like an expanding Universe to a shrinking inhabitant.

So I wrote a quick Unity Universe Simulation to show the perspectives of a shrinking Universe and an Expanding one. Try the above link (Made with Unity 4.6rc 3).

As you can see it looks the same!

 

Very random. Also, you're shrinking the physical objects in your shrink (scaling), but altering their position when you expand. Pretty sure when people talk about a shrinking universe, they're referring to everything moving closer to a theoretical centre (rather than away from it, in an expanding universe).

 

Yep, expansion is the theory that things are physically moving away from each other.

The alternate theory is that this apparent expansion is just a symptom of observing a shrinking universe, not a imploding universe.
