    Clock Universal
Click For Summary
The discussion centers on whether the universe's spacetime can have its own clock or periodicity. It concludes that clocks are fundamentally built from matter, making the idea of spacetime having an independent clock implausible. While concepts like the block universe and Many Worlds interpretation suggest varying configurations of spacetime, they still rely on matter for measurement. The expansion of the universe can synchronize distant clocks but cannot serve as a clock itself due to its unpredictable nature. Ultimately, the consensus is that spacetime cannot exist in isolation from matter, and any proposed periodicity remains speculative.

This is something I may want to discuss. I'm learning this bulletin board. Can I quote this reply when starting a new thread or maybe we could open a conversation to rattle this reply around some time? Thank you also for the reply.
Either would be fine with me, but as you can see, I may not notice...
