&quot;created by observation of cyclical systems&quot;. Can you elaborate on that? I&#x27;m not sure what you mean, but it sounds interesting. It seems to me we believe time &quot;exists&quot; because of causality; things that happen at &quot;this moment&quot; affect things that happen &quot;in the future&quot; but not things that happen &quot;in the past&quot;. We&#x27;ve also predicted and measured certain weird things about time, such as how it can go faster or slower.
