The WORLD, my dearest dear World is becoming smaller day by day while the great wide Universe is expanding ever since. Where do I fit in this tug of centrifugal pull of expanding Universe and reducing Earth....
Yes, yes, I know my understanding of the above two concepts seems to be utterly wrong as how I described above. The ever expanding Universe came to me in last few years of School. Its a very very intriguing thing to try to understand and study. Those days I used to think a lot of this kinds, driving deep into it, deriving my very own theories.
For instance to create a centrifugal force you need to have an object in rotating motion thus leading to a reactive force that tries to keep the object in motion to move on an outwardly straight line at any point of time of its rotational motion. (take a quick breather here!) For instance if you have a heavy ball attached to a long string and a comparatively smaller ball attached with the heavy ball with another smaller string. Now with opposite end of the longer string in your hand, swing the heavy ball so as to create a rotational motion. At a point when you achieve peak of your rotational force you will see that the smaller ball, the heavy ball and your hands are all in a straight line(ignoring bent due to other natural forces).
Also you can visualize that to keep a body in a continuous rotational motion in an attempt to achieve optimum centrifugal force the rotational force has to be constant at all times. And since we can not achieve a forever 100 percent efficient force a near continuous push and pull force is required that deforms the circular form of path of rotation. Each act of push and pull reached its optimum limit before changing into the other. Ok, so that is also the reason why the Earths rotational axis is elliptical rather than circular, the force is not same is all point and hence there must be a push-pull active force acting. The same also explains elliptical nature of pictures of other galaxies. And also the High Tide due to Moon's path around Earth- point of change of Push-Pull force...ah! ha!
Thus the whole universe is under a constant push and pull motion withing itself. For such a big Universe to perform such a motion would definitely take millions of light years. How long does our Solar system takes to perform such an act, definitely a few hundred thousand years. And right now I am sure we are in a phase somewhere between of constant push leading to an expansion theory. But there will be a time when we will be in a phase of eventual contraction, bring all solar objects closer and closer to each other, reducing the distance between planets, and moons and meteors and all; imagine the affect of such a change to life on Earth. The atmosphere will become more dense due to immense pressure, temperatures will fall and change rapidly, growth of life will slow down and so many other thing, meteors slamming on Earth's surface, super tsunamis will be a every day event. Hmnn... Man, this explains extinction of Dinosaurs also, really large ones died of meteoric hits and extreme temperatures change, mid sized ones deformed into other beings-crocodiles maybe and went into water; the relatively smaller ones became even more smaller may be they became lizards. WoW! a giant T-Rex became a humble House Lizard.
Now I don't even seemed to care what I understood and tried to understand and what I derived than an how I came to my own conclusions. I am sure I am not the only one to do so in their own course of becoming grown-up's. But I definitely try very very hard to step out of this circle I am in and look at it from outside, I barely get time and strength enough.
