Time is necessary for change, not existence.

• mr_toad 1mo ago
  Time is change that happens in a continuous manner. It’s still possible to conceive of change happening in an unordered unpredictable way that is not like the smooth ordered time that we experience. In a gravitational singularity spacetime breaks down. You could argue that time stops, but it’s also valid to argue that causality breaks down and we can no longer make any predictions about the future. Just because we don’t have a theory describing what could happen, doesn’t rule out that something could happen.
