If I were high right now I'd definitely know the answer.

It can be likened to dark matter I guess, where we can measure the effects but don’t know what it is that we’re measuring.

Obviously it’s a measurement, but fundamentally what is being measured? Mass, heat, etc we (at least think) we have somewhat of a grasp on, but time seems a more elusive concept. The passage from one moment to the next, but why does that passage even occur at all. What is a moment?


Feynman’s Sum over Histories theory led him to describe time simply as a direction in space. Feynman’s theory states that the probability of an event is determined by summing together all the possible histories of that event. For example, for a particle moving from point A to B we imagine the particle traveling every possible path, curved paths, oscillating paths, squiggly paths, even backward in time and forward in time paths. Each path has an amplitude, and when summed the vast majority of all these amplitudes add up to zero, and all that remains is the comparably few histories that abide by the laws and forces of nature. Sum over histories indicates the direction of our ordinary clock time is simply a path in space which is more probable than the more exotic directions time might have taken otherwise.

Time started when the first human became aware of his/her existence.

So time is a measurement relative to each humans existence.

It can be freaky. I just realized today that it's been exactly a year that I moved into this condo, but if I didn't know the date and somebody asked me how long it had been I'd say 5-6 months. When you're days start running together a month can pass without hardly noticing it.

Einstein did not believe time existed in the conventional sense. This is what he wrote to the family of his recently deceased best friend;

"Now he has departed from this strange world a little ahead of me. That means nothing. People like us, who believe in physics, know that the distinction between past, present and future is only a stubbornly persistent illusion."

Past present and future are an illusion. The past certainly no longer exists. The fact that there even is a future is in no way guaranteed. Greek philosophers argued for centuries over the paradoxes of defining the present - is the present now, oh wait it's already gone into the past which doesn't exist anymore, is it now?

So the past isn't real anymore, the present is undefinable so all we have is the hope that there is a future? This is truly crazy stuff, intuitively we accept time but the greatest minds in human history have yet to, despite immense effort, define the nature of what we call time and thus the nature of our existence and the answer to the ultimate questions "what are we and why are we here?"

Where the observer & observed are relative to light at the moment they all come together.

Entropy is times arrow.

You can measure “time” at any point in the universes history if you could calculate all of the entropy.

It is a linear progression of the current universe cycle we are in. We will either collapse internally, or merge with another universe and reset the clock.
