Space, Time and Black holes!

I am sure that anyone and everyone who is a science freak would have at sometime of one's life fantasized about these three aforementioned,very elusive quantities . And I am more than doubly sure that a greater science freak would have read 'A Brief History of Time'-By Stephen Hawkins . Though it is really out of bounds ( w.r.t understanding)for the laity, it definitely gives a profound insight into Black Holes and the intimate relation it shares with both time and space.

For the sake of the uninitiated , and for later benifit( ie where i shall discuss my own opinions),let me first outline the basics required of this dicussion. (For those who already know this, please bear with me). The universe, as we all know, has around about 10 to the power 11 galaxies, and it is stipulated that each of these galaxies consists of around about the same number of stars. Now these stars can be classified into 7 groups in accordance to their size ( i dont exactly remember the classification but it goes like G,K,L...). Our Sun comes in the medium size range. Now as the size differs, so does the way of 'dying' of these stars. Stars die due to the converstion of hydrogen atoms into heavier elements through fusion. Black holes are formed when particularly large stars 'die' ( which occurs by way of enlargement and culminating in a supernova explosion).These black holes then become the centre of an extraordinarily strong gravitation force.So strong that even light cannot escape. Often such points in space are also called ' Singularity'. Secondly Surrounding each black hole is a region called ' event horizon'( which can simply be explained as the point of no return for light!)As has been explained by various scientists : To get a fair idea about a black hole, consider a perfectly elastic rubber sheet. Now if a ball is placed at the centre of this sheet, it keeps on sinking( for want of a more suitable word) in the sheet, theoretically, if it is perfectly elastic, the ball should sink till infinity.

Now comes the interesting part. Einstien praposed time to be the fourth dimension. As in, the motion of an object can be perfectly described by its position at a particular instant and the time it takes to reach there . Now if we had marked the rubber sheet with a grid ( one axis as position and another axis as time) we would find that at the point where the ball was kept, the grid converges to one point. To better understand the point, i can rephrase it as ,all position points meet at the same time and all time becomes one!! And with this remarkable observation, you will find a number of open avenues viz: time travel, worm tunnels, and the existance of multiverse and its origin.

From here on i leave behind what are the facts, to what i believe ( ie my thoughts and opinions related to the topic). There is an ongoing discussion between the members of the scientific community about the nature of universe and the origin. Some believe that universe started with a big bang( out of seemingly ... nothing), others believe in an expanding and contracting universe. I , find myself more inclined to the later theory... however there still exists a basic question, where did all this matter come from??

Well here it goes...after reading i've come to the conclusion that probably the universe doesnt exist as a singular quantity . What if say the universe ( which is of course by name singular) is not actually singular, but a multiverse( let us take a dual universe system for sake of simplicity). Confused? Ok lets take two balloons , and connect them at their spouts! now suppose one of them is full of air and the other is empty. If we consider the reaction force of air as negligible, in the presence of an initial driving force, the balloons will expand and contract alternatively( with some time period of oscillation). While one expands, the other contracts! Now suppose these two balloons were two different universii. The situation becomes interesting doesnt it? Two universii co- existing in a symbiotic expand-contract relationship.However this does not explain how the mass initially got there.

To make it more interesting... what if the two balloons were the same universe but in completely different times? like for example:I am somehow sharing information with my future self/ past self!! To be more elucidatory, what if right now our universe is getting mass from itself in another time? and thus expanding, while its other self is contracting! There can be many such selves in various times, expanding or contracting.Since universe is contracting and expanding, there will be a time when the mass is zero( after end of contraction) but it is still connected to its other self, which at this instant will start pouring into the empty verse!! ( Big bang!!)

Expanding this line of thought, with time as a running parameter between all these universii( i call them universii as they are still singular in thier repective time frames), there can be infinite number of universii, each separated from the other by time instants( very small fraction of seconds) just like there can be infinite points on a circle. I compare them with a circle as this activity of the universii has to be cyclic, with the lowest point as big bang, and the highest point as the direct opp. of big bang!

Now you may ask how these universii are connected. Through black holes and worm tunnels of course! It is postulated that once something enters event horizon, the mass is destroyed and it becomes pure energy spiralling around the black holes( like in a whirlpool). However what happens if some of the energy falls into the singularity itself? How can we lose information? something has to be conserved! Now using my line of thought, what if say black holes form ends of worm tunnels? like ends of a pipe. Something entering from one end has to exit from the other end. Now if these two ends can be assumed to be in different times..... I suppose u can draw out where im leading to. We hit upon the medium of transfer between two universe. Something is amiss isnt it? How can the black hole emit energy/mass? well every black hole also has a life cycle( as has already been proved by scientists). One half ,it absorbs and the other half it emits.Also there are white holes which are exact opposites of black holes and pulsars and quasars.or it could just difuse out at the other end forming a cosmic cloud. When this cloud becomes massive enough it is turned into a star!!! And since all time becomes one ( as i have already explained how) at black hole, the mass entering at this instant could reappear instantaneously at the other side at a completely different time!!! Hence one more fascinating prospect.... Time travel!!

Whew... i Dont know how many got through what ive said. However, all this may sophomoric and can even be totally wrong . What matters is this is what i thought could be possible and here ive shared it with you.
