Anyway science have had big problems finding out what dark energy is, the vacuum energy turned out to be wrong and the LHC does not seem to find particles the can explain this force either, and yet our universe is supposed to be mostly dark energy, it should be everywhere. maybe the reason we don’t find it is because the dark energy is really not in our universe at all.
What if the observable mass in the universe is being pulled to a massive shell outside of our light cone? We live in an egg and we are the yolk. Can this hypothesis be disproved?

Can this hypothesis be disproved?well the most obvious answer is that the net force of gravitational attraction within a uniform shell is zero. For a force to exist the shell must be non-uniform, yet the expansion we can measure is all pretty homogenous and isotropic
1. The shell is uniform; in which case no force will be felt within the sphere

The shell is uniform; in which case no force will be felt within the sphereThis would be true if the shell were infinitely large beyond our visible universe. If we were encased in a finitely thick, uniform shell, we would only experience no force at the center and all points equidistant from the center would feel an equal pull in their respective directions.Any point away from the center would feel a more strong attraction toward the side they were closer to. For the pull to be significant, you would need to be sufficiently far from the center and the shell would need to be sufficiently thick though.

Also I think I heard a theory about bubble universes with our universe being just one of many universes. If that is the case maybe the void in between these universes acts like a vacuum sucking our universe in to it.
