Is time a fundamental part of reality? Quiet revolution in physics suggests not

- Time is perceived as a fundamental, irreversible feature of reality, yet physics struggles to define it.
- Modern physics frameworks (general relativity, quantum mechanics, cosmology) treat time in incompatible ways.
- Einstein's relativity showed time is elastic and relative, not universal, forming spacetime with space.
- Quantum mechanics treats time as an external parameter, not explained by the theory itself.
- The 'problem of time' is a major obstacle in unifying physics, as time behaves unexpectedly or disappears in combined theories.
- Entropy and the second law of thermodynamics explain the arrow of time but don't fully solve its fundamental nature.
- Information theory suggests time emerges from irreversible information recording in the universe.
- Spacetime may store quantum information, making it an active participant in physics rather than a passive arena.
- Dark matter and dark energy might arise from accumulated informational imprints in spacetime.
- Black holes and quantum experiments provide testing grounds for theories linking time to information.
