What is time?

Time as a term has always been major subject in science, religion and philosophy, yet none of if it is provable.

We already know that time we perceive is relative time, which is a measurement of perceivable objects in motion (like the moon or sun). From these movements, we infer the passage of time. ''Time is the fourth dimension and a measure in which events can be ordered from the past through the present into the future'' right? But what if those 3 aspects are made up by our mind. I tend to think that time doesn't exist, it's made up concept.

It is easy to think that there is beginning and end for something just cause we associate it with human life. It's much harder to accept that something can just have no beginning or no end. But why is it harder - we have examples of infinity( no end ) and no beginning. For example, π(pi)or -π if you look it right way it has no beginning or end. Another example could be The Universe itself. It is improbable to tell when exactly everything ''started''. Started out of nothing? And again, its easier to accept the idea that time is human made up concept. Than actually believing that something can ''start'' out of nothing.

What if our universe is exactly like π (Pi) - just endless sequence of random possibilities (chaos), with no beginning or end, with possible similarity's but never exactly the same. Every day is different and every next day will be different than any other day that there ever will be.


P.S. It's part of the fabric.
