We have all recently been taught that the universe is expanding but if one takes a deep dive into Einstein's statistical universe it is an illusion of time from our perspective. This is because the universe is dispersed like a sponge with great voids surrounded by dense filaments of visible and dark matter that slows time but the voids have an opposite effect on time . The farther you measure through many voids to a distant point the more time will be skewed to our point of view.

The universe is not expanding in the way we first thought, based on Nobel Prize-winning ideas regarding Type 1A supernovas. We jumped at the clear illusion because we tend to think all regions of space are the same as where we are. We don't live in voids. Time is very different there.

It just goes to show ya how easy we jump at the Occam Razor solution when in fact there are forces beyond our first thought that are not obvious.
