  • 💨 Fictional stories often portray time freezing as a way to depict the absence of change.
  • ⌛ The smallest interval of time, known as a Planck time, represents the change in position of a photon.

Questions & Answers

Q: What happens if time were to stop?

If time were to stop, everything would freeze, including the movement of photons, which means no light or visibility, no heat, no ability to breathe or move, and even brain activity would cease.

Q: Does change only occur within the passage of time?

While some philosophers argue that change only occurs within the thing that changes, others propose that change also exists in the relation between the thing that changes and everything else.

Q: How does the concept of a B universe differ from an A universe?

In an A universe, time flows like a river with a definite past, present, and future. In a B universe, time does not pass, and the present is like an indexical, while past and future exist equally.

Q: Can change and the passage of time be understood without each other?

Some philosophers argue that change and the passage of time are inseparable, as the concept of change would not make sense without time passing. However, others contend that change can still be understood in a B universe where time does not flow.

Summary & Key Takeaways

  • Time is often associated with change, as objects have different properties over time.

  • In most fictional stories of time standing still, the protagonists notice because everything around them is frozen.

  • Time can also be measured through the smallest interval known as a Planck time, which represents the change in position of a photon.
