â€œTimeâ€ is the most used noun in the English language, yet it remains a mystery.
1. Time exists. Might as well get this common question out of the way. Of course time exists â€” otherwise how would we set our alarm clocks? Time organizes the universe into an ordered series of moments, and thank goodness; what a mess it would be if reality were complete different from moment to moment. The real question is whether or not time is fundamental, or perhaps emergent. We used to think that â€œtemperatureâ€ was a basic category of nature, but now we know it emerges from the motion of atoms. When it comes to whether time is fundamental, the answer is: nobody knows. My bet is â€œyes,â€ but weâ€™ll need to understand quantum gravity much better before we can say for sure.
