Some theorists have put forth the idea of an atemporal universe - ie. a universe without time - claiming that time is an illusion or abstraction created as a placeholder for what is really entropy. https://phys.org/news/2011-04-scientists-spacetime-dimension.html So they're claiming that there's no need to have a time dimension along which we all march forward, when we can simply chalk it all up to entropy. Rather than simply re-naming the Time axis/dimension to an Entropy axis/dimension, they assert that the Time axis/dimension was never really an axis/dimension to begin with, pointing out that it's not really possible to travel along this so-called axis/dimension - ie. we can't travel in time to the past, nor can we travel in time to the future. Their case is that progression of time is really governed/affixed by progression of entropy, and that time is just a numerical index/order of change in the universe. As I find this idea to be very appealing - it seems to simplify things, a la Occam's Razor - I'd then like to discuss the legitimacy of this idea. I'd also like to further ask if it's possible that Quantum phenomena/effects are at the root of driving Entropy increase in our universe, and are therefore the root cause of what we call "Time".
