Time Loop
They say that the future cannot be remembered. It is only the past that has happened can be recalled. Only some very highly intelligent beings ask a question like this- 'why is time moving the way it is moving?' Well, for one there is the arrow of time (there are three arrows actually) which like all arrows, points straight. Hence we move in a direction that the arrow is following, and arrive not ahead, but always with the arrow. It is almost implusible to think in terms of this current universe and still say that time can run backwards.Almost all laws and theories are based on the observable universe around us ie, an ever expanding universe. And with that expansion also comes the arrow of time moving in the same direction. So it is a foregone conclusion that time will always be told in past and present, never in the future. Nearly so. How about time not being an arrow? Can it not be a loop? Yeah, lets take a plain paper and draw an elongated loop and call it the time loop. The loop would have two curves(since it is elongated), so on each curve one can write either exanding universe or contracting univese. Theoritically it is possible to have a contracting universe, just the opposite of the current one. Now what happens to time? Well it looses all sense of direction! A bloody loop can go any which way and never be able to point either the future or the past! What is behind us can be termed as future because time is now bound by a cyclic motion instead of a linear one. The absurd idea of time is further doomed to more absurdities by this simple change of thought.There are however two points in this loop which do not satisfy physical laws. These are the points within the loop which has the beginning and the end of the contraction and expansion. During such a phase, all laws of physics break down because of the unpredictibility of the next moment. Considering that big bang is a dependable scenario, then it is universally agreed that the very next moment of the big bang is not measurable and uncertain. Otherwise if time is considered to be constant with no particular beginning, then it suits to say that it holds true even if some accepted laws do not hold during a singularity. So the ageless miracle of matter exploding and expanding and finally turning back to gather in a point does allow an endless rotating value of time. From past to present, then to furure, and furthermore to past and again to present! It is not so absurd anymore. A loop solves the great promblem temporarily.We can remember the future after all.
