The Glitch in the Universal Clock
While we experience time as a flow, the fundamental equations of physics suggest it might not exist at all.
Listen in the Fylom app.
The Wheeler-DeWitt equation suggests time is not a fundamental ingredient but a secondary property of the universe.
The Block Universe model proposes that all moments in time exist simultaneously like a four-dimensional loaf.
Entropy defines the arrow of time as a transition from order toward disorder rather than a flow.
Twenty-four thousand ultracold atoms were used to simulate a universe where time emerges from quantum entanglement.
Time functions as a relational property between internal subsystems rather than an external, absolute background clock.
Like temperature, time is a macroscopic property that only appears when vast numbers of particles interact.

- The unsettling possibility raised by quantum gravity is that time may not be a basic ingredient of reality. It may be something that emerges only inside the universe, from entanglement, entropy, and relationships between physical systems — while the deeper quantum structure underneath may have no ticking clock at all.

Fylom generates episodes like this on any topic you're curious about.
Fylom episodes are researched, written, and voiced by AI. Automated checks help catch inaccuracies, but episodes aren't reviewed by a human and AI can still get things wrong. Treat them as a starting point, not a source of record — more in our accuracy disclaimer.
