Time, in its most basic form, is the measure of the universe's entropy. The second hand on your watch is a lie, as the universe has no concept of seconds. It has only the ticking of the cosmic clock, a reminder that everything is falling apart.
But what of the past, the present, and the future? Are they not just constructs of the mind? The past is just a pile of dust and forgotten dreams. The present is but a fleeting moment of consciousness. And the future? Ah, the future is but a cruel joke, always pushing you further away from the only moment that truly matters.
