"the "fourth dimension". By combining space and time into a single manifold called Minkowski space in 1905, physicists have significantly simplified a large number of physical theories"
Theories, they are backed up by facts yes it's possible the universe is 4D but there are multiple theories (not hypothesis like creationism) which say otherwise.
Heck there's a theory the universe is 2D, but not a hologram.
The universe could also be a simulation where time goes forward based on actions created by life and chaos.
But for now, the "theory" that the universe is 3D seems to be the most likely.

Some things break apart over time, other things gain order over time and that is a 5d process.
It's really quite simple.
Yeah, 4D is just another movement through time. How can we define going "fowards" in time when we have only observed one form.
