Time is circular!

I've heard this phrase today- 

"Time is like a river, but the river is circular"

in a rather popular show- 'Da Vinci's Demons'
which left me thinking... What if this is really true?

Now, this hypothesis seems really far fetched, and as a fan of 'Doctor Who', it doesn't hold much weight being typed by my hands. I'd say neither did it hold much weight in my mind until! I decided to delve into some metaphysics, and then this happened & the thought became worthy of the blog!

Facts & Observations: 

• Electron revolves around the nucleus, Earth around the Sun... Basically, everything is revolving around something where nothing is at rest or at motion in this universe!
• Time and space are relative due to the efforts of Einstein, which is the basic fundamental in explaining how time travel, warp speeds, worm holes, and the T.A.R.D.I.S works(though they might be a little far-fetched).
• Moon moves 4cm away from Earth each year, i.e no revolution is perfect as is nothing in the universe and we can't go back to where we were after one complete revolution.
• Even humans, if their senses are turned off start walking in circles instead of straight line.

Every thing in this universe, be it matter or light, depends on each other and co-exists in a balance. From the structure of an atom, to that of the Milky Way, the bending of light due to gravity, to the existence of black holes, our universe has a balance.

The straight line just doesn't happen anywhere in the universe, so why should it happen with time?

Now, this might all seem unrelated, or coincidence,  but to me, these facts and that quote seemed to make sense! 
I arrived at the conclusion-

"Time moves in a circular path, where at the end of its revolution, we are at a slightly different point than the one we started from"

 What if there is a deeper relation between time and space, where we are moving in a spiral in Space as well as in Time?

What if the Big Bang didn't just create all the matter in the universe, but the time too, and like the Moon around the Earth, its revolving around something?

in the simplest possible way, what if-

Dinosaurs --> Romans --> Present --> Star Wars --> Slightly different Dinosaurs -->?

 where the events in our present and the future leads to a slightly different past and the past, present and future are nothing but the points on this spiral?

What if we are 'predestined' to be at some point in time, and only really huge effort would slightly deviate its course(equivalent to asteroid striking the Earth)? The progress, the future... everything in reality leads to lets say total annihilation and after some billion years, it'd all start over again like it did with the earth? 
Those 'Ancient Civilizations' actually are just our future ones, which are deeply buried and forgotten in the past!

What if, time is localized? Like the revolutions of planets around the sun, and the revolution of sun into the milky way?
What if, we have our own time loop we are stuck in and sun has its own, milky way its own, but, closely interrelated like all the planetary bodies are? like there's no Time, but many loops of time, some larger like that of the sun, and some smaller like that of the moon?!

Due to stuff like Space-Time continuum, it might not be so far-fetched to imagine that this might all be true.

In this lecture by Brian Cox('The Science of Doctor Who'), he postulates about bending the space-time graph to make our future actually making us travel to the past.

The parallel universe do not seem so far-fetched by this theory now. We know that there are infinitely many parallel universe and they might just be the adjacent curves in the spiral!

Not the final draft by any means, but really, what do you think?!
