How logic alone may prove that time doesn’t exist
https://theconversation.com/how-logic-al...ist-227817
INTRO: Modern physics suggests [the flow of] time may be an illusion. Einstein’s theory of relativity, for example, suggests the universe is a static, four-dimensional block that contains all of space and time simultaneously – with no special “now”.
What’s the future to one observer, is the past to another. That means time doesn’t flow from past to future, as we experience it.
This clashes with how time is conceptualised in other areas of physics, such as quantum mechanics, however. So is time an illusion or not? One approach to find out would be to try to prove that time is unreal using logic alone... (MORE - details)
But the "mistake" that the article below itself seems to make is in alternatively treating the experience of time as fundamental, when the latter is a product of the brain (in the context of a prevailing science view that treats anything subjective -- secondary/emergent -- as incapable of being primary).

The mistake at the heart of the physics of time

EXCERPTS: Even if, mathematically, we can divide time into smaller and smaller chunks, we could not expect to measure such shrinking time intervals ad infinitum.
Infinitely divisible, physical time is a mathematical abstraction. The time line, a straight line covering the real numbers, is a useful tool for modeling time-varying phenomena with roots in the late Middle Ages (see chapter 2). It should not, however, be taken as representing the reality of time any more than a clock dial does.
[...] Clocks don’t reveal the true nature of time; they are tools invented to abstract certain aspects of the experiential flow of time and to measure them in a systematic way.
[...] The map serves a clear purpose: the mathematical description of natural phenomena to the highest degree of precision possible. But you cannot be a mapmaker if you cannot see what you are mapping. The mapmaker should not forget what cannot be included in the map—the experience of walking the terrain, the biting chill of the mountaintop, the dappled light through the trees of the forest. Which details are important for which purpose? The map will get its users lost if the mapmaker does not understand its purpose... (MORE - missing details)
