But could this be said of the universe as a whole? The universe is a four-dimensional extension, permeated by a kind of weft that sets a limit, namely the speed of light, on the shapes within it. Time is not an absolute, but a human convention.
[Addition after finding an alternative]
There's an alternative to this in the ideas of Ahmed Farag Ali and Saurya Das ("Cosmology from quantum potential." Physics Letters B. Volume 741, 4 February 2015, Pages 276–279 - see https://phys.org/news/2015-02-big-quantum-equation-universe.html#jCp)
It rests on a non-standard approach to quantum theory due to Bohm - but I feel that we still have no fully consistent approach to applying quantum theory on a large scale.
At the core of this is the fact that we still have no universal approach to physics, encompassing the smallest particles and the entire universe. Our physics remains a patchwork.
