Time might not exist – and we're starting to understand why
Time might not exist – and we're starting to understand why
The article delves into the enigmatic nature of time, highlighting how physics struggles to reconcile different definitions from classical mechanics, Einstein's relativity, and quantum mechanics. It explores concepts like coordinate time, time as a dimension in spacetime, the Wheeler-DeWitt equation which suggests time might be an illusion, and the arrow of time linked to thermodynamics. The author discusses quantum entanglement and its potential role in understanding causality and the flow of time, suggesting that time might be a multi-faceted concept that retains different properties depending on the context, or that our perception is an approximation.
Note
this was a helpful breakdown of the current framework for "what could time possibly be?"
unfortunately, it remains unsolved with all signs pointing to "not real" despite it being very real for us. quantum entanglement and quantum gravity are posited as central to why we experience time on the "inside".
the idea of retrocasuality though is mind boggling.
