>>12185413It didn't "go" anywhere. There is no yesterday, there is no tomorrow. There is only "now" and it is ever-changing. The concept of time as a substrate upon which all things are formed and changed is flawed - rather, it is the constant change of all things that is "real" and this concept of time is really just movement - spacetime, you dig?
Riddle me this - if time is a constant, then why is it relative? Why is time influenced by gravitational waves? Why does moving at the speed of light have an effect on time?
YOU are time. We are all time.
Perhaps a better question than why is time would be: why is anything, at all? Why is there something rather than nothing? Perhaps the questions themselves are a better answer than any explanation that could be offered.
