Suppose there is a static 3 dim space and a dynamic changing 4 dim space. Without that supposition, lots of problems in physics remain puzzles. With it, lots of puzzles are easily resolved.

Energy in 4 dimensional space, where the fourth dim is proportional to the distance light travels or the time it takes for light to travel that distance, has 4/3 as much energy per dimension as does 3 dim static space. Hence, dim space a 4/3 length L when 4 dim space has a distance of length L. This appears to account for space expanding. A supernova’s distance from Earth measured in the 4 dim space where light moves, using redshift, should appear to be 3/4 as luminous when comparing type 1A supernovas, because in static 3 dim space the supernova is 4/3 as far. Other data is consistent. Energy density for dark energy (so called) compared to matter energy density is in the ratio [ E/ L^3] : [ E/ {(4/3)L}^3, which is 4^3/3^3 which is about 0.7033/ 0.2967, as has been observed in astronomy.

There are numerous examples of this 4:3 ratio occurring a variety of different natural phenomena, as set out in various article in my projects dealing with the 4/3 laws and DE.

Or maybe not?
