There's no escape,all efforts and techniques have failed by now.Thus surrender is the only option left,as scary faces approach,the last words which come out of every child's mouth are "uniform pe mat dalna please".
The day before holi in school is no less than a war,it used to be the day when we don't check whether we have all the books according to the time table but make sure that we have all the weapon and ammo ready.Special instructions were given by mother to take care of the uniform..."No dark and permanent colors".As i entered the school premises,every known and friendly face appears to betray.trust is nowhere found among ourselves.Some were smiling because they knew were prepared for after session war and others like me were afraid and worried.the only motto for the day was "Don't get the uniform spoiled" otherwise a good scolding at home is waiting.
The day passed soon enough,heartbeat rises with the ringing bell.As we finished our afternoon prayer,we get our diaries checked and form ques to finally head out of the school.As i stepped outside,there was silence,the silence before the chaos..because nobody will ever approach you across a perimeter of 10 metres around school.It will start just after the first turn,near the school and in the park.The park which used to be the place of our rendezvous in holidays,today becomes the slaughter region..everyone familiar or unfamiliar will tame you,friends are foe here.Preparing yourself and arming is the final option left when one have to pass through or near the park to get to your home.
The view of the park and surrounding area can scare the hell out of anyone normal..with students running away from colorful monsters just to save their prestige...their school uniform.you are not suppose to get caught because once you have,you will become one of them.I entered the region with my ammo,A big packet of scented yellow gulaal in this case.I was ready to face it...face to face with all my courage and strength,which only last for splits of a second.And in another few seconds i am one of them.I was colored by with my own colors but somehow i managed not to be painted upon with any permanent color.As i get out of the region to head back home,i noticed my friend Rohit Bora going for home accompanied by some other guy.I decide to color him because i don't get the privilege to color someone on my own.though he was all colored,face and hairs...but i want a mark of my own.So,i sneak behind him taking the leftover gulaal in my hands.But the winds of bad luck blown....again.He suddenly turned and notice me,with in an instant he emptied a small plastic box over my head and the other guy added water from his bottle....hmmmm and the final dish of the ingredients was a purplish blue color.
I managed to save my uniform but the cost i paid was a purlish blue scalp for atleast next 7 days.
The protest at India Gate is gaining momentum with time,despite the various efforts made by the police to the protestors. Although 7 metro stations have been closed,people from different places are reaching India Gate.
The picture is clear this time we won't stop,we want strict laws against such crimes.
Today is the second day of the protest,student from different colleges,people from different places gathering for one cause.Where people from have managed to come at India gate despite the restriction imposed.President of India don't have time to come outside and listen to our voice.
The people are not lead by any political party or leader.They came on their own,for the justice and a safe place where women can live freely..
Despite being a democratic country,where we have the right to express and protest peacefully,Police lathi charged on protestors,they don't even left girls.This is the democratic country in which we live.
Instead of the ongoing protest in Delhi...new rapes and molestation cases are coming to light.
This indicates that such people don't fear the current law anymore.
A maximum of 7 year imprisonment is the punishment according to current law.
A collections of some quotations and poems of Rumi.
When the world pushes you to your knees, you are in the perfect position to pray ~Rumi
However much we describe and explain love, when we fall in love we are ashamed of our words~Rumi
A life without love is a waste. “Should I look for spiritual love, or material, or physical love?”, don’t ask yourself this question. Discrimination leads to discrimination. Love doesn’t need any name, category or definition. Love is a world itself. Either you are in, at the center…either you are out, yearning.
I smile like a flower not only with my lips but with my whole being. ~Rumi
One day I feel confused and down, the next I can reach the sky without you I am never calm. In your absence people ridicule me, but when you come I don't mind what they think or say. ~Rumi
Time travel...the idea itself is much fascinating when one think of it.With this idea comes various thoughts regarding what we will do after being travelled through time?Most plan(actually dream of) to go to future and see their future life and so that later after returning back to present they can prevent any miss happening yet to occur.
But many think to go back in time,to prevent and rectify whatever wrong has happened with them,may be to save their loved one or to correct grieved mistakes committed by them.
Everyone will have their own plans...but what physics say about,what you can do after travelling through time?
Since nobody has actually traveled through time yet so there are two open possibilities....
Either we will be able to change the past or we won't be able to change the past.
The idea of being able to change the past seems fantastic but by making even minute changes in the past you can drastically change the future not only your...but of whole universe.
If you have watched the movie Men In Black 3 then you will understand what i mean.The movie shows clearly that how an evil alien change the future by killing the agent K in past.
The ideas picturised in science fiction are not the imagination of directors or producers but are the concepts adopted from physics,for example teleportation you may think that it is not true but teleportation origin from the equations of quantum mechanics.Teleportation is based on the "spooky" action at a distance (as Einstein called it) between the entangled particles(for detail reading search for Quantum entanglement and Quantum teleportation).Scientist have successfully carried out teleportation with photons.Changing the past can not only change the future drastically but it can also give rise certain paradoxes..for example the most famous Grandfather Paradox. The Grandfather Paradox:- The grandfather paradox is a proposed paradox of time travel first described (in this exact form) by the science fiction writer René Barjavel in his 1943 book Le Voyageur Imprudent (Future Times Three). The paradox is described as following: the time traveler went back in time to the time when his or her grandfather had not married yet. At that time, the time traveler kills his or her grandfather, and therefore, the time traveler is never born when he or she was meant to be.Now,if his grandfather died before having children then the time travelers parents would never been born and in turn there will never born the child which will go back in time to kill his grandfather...thus the time travelers grandfather must be alive.The situation demands that the grandfather should be dead and alive at the same time...hence a paradox. Here's a video as well to understand more clearly..you will find many like this on youtube.
It is due to these paradoxes that the idea of time travel is always been controversial topic among the physicists. Now,the second possibility-which restricts us to make any change in past. A logical question may arise in your mind that how can it be possible that i travel to past and cannot change it by anyway? It can be possible because by travelling to past you will only b full filling the need of the past. Let us consider a hypothetical situation to understand this.. When you were 12 years old you met with an accident,however you survived,having some scratches here and there... because someone saves you but the accident had an psychological effect on you and you clearly don't remember what actually happened that day except this that you went to pick the ball from the road. Later,You grew up to become an eminent scientist and you built a time machine.Now you decide to travel back in time to figure out what actually happened THAT day of accident.You set the date in time machine to the date when that accident occurred.As you reach there(back in time) you find your-young-self playing in the open park near to your house,you remember up to this clearly.You stare yourself for sometime and started to wait for the accident to occur.You wait for considerably long time and started to loose temper then suddenly a ball hits you,you angrily throw the ball aimlessly which landed on the road.Soon you see your young-self going to retrieve the ball in hurry.You notice a truck coming in speed towards the boy(childhood you) which the boy didn't noticed.You abruptly run to save yourself being hit by the truck,just in time you forcefully pulled the boy aside of the truck..resulting in a roll down to the ground.You and your young self got some scratches here and there..and your young self has been fainted during all this. So now you understand what actually happened that day,it was you who threw the ball thus causing the accident but it was also you who saved yourself from the accident and since you didn't observe the truck coming towards you when you went to pick up the ball and also had been fainted during all this that is why you don't remember what happened at that day in your childhood. It can also be realized by again consider the grandfather paradox.In the paradox ,you plan to go back in time and kill your grandfather in past.The act of killing is associated to the past...things which have already happened.That when you in your present is planning to kill grandfather the attempt of killing the grandfather has already happened because it happened in past and since you are alive it means that you have already failed in past. No matter how,maybe you miss the shot or forgot to fill gun's magazine...it can be anyway in which you can fail to kill.Your existence in future showed that your grandfather had survived the past. This is first proposed by David Lewis in essay The Paradoxes Of Time Travel. And i strongly believe in this picture of time travel. However this second possibility also gives rise to a very interesting paradox,this paradox i read in Michio Kaku's book HYPERSPACE,which was originally from Robert Heinlein classic story "All You Zombies" :- A baby girl is mysteriously dropped off at an orphanage in Cleveland in 1945."Jane" grows up lonely and dejected,not knowing who her parents are,until one day in 1963 she is strangely attracted to a drifter.She falls in love with him.But just when things are finally looking up for Jane,a series of disaster strike.First,she becomes pregnant by the drifter,who then disappears.Second,during the complicated delivery,doctors find that Jane has both sets of sex organs,and to save her life,they are forced to surgically convert"her" to a "him".Finally,a mysterious stranger kidnaps her baby from the delivery room. Reeling from these disaster,rejected by society,scorned by fate,"he" becomes a drunkard and drifter.Not only has Jane lost her parents and her lover,but he has lost his child as well.Years later,in 1970,he stumbles into a lonely bar,called Pop's Place,and spills out his pathetic story to an elderly bartender.The sympathetic bartender offers the drifter the chance to avenge the stranger who left her pregnant and abandoned,on the condition that he join"time travelers corps". Both of them enter a time machine ,and the bartender drops off the drifter in 1963.The drifter is strangely attracted to a young orphan woman,who subsequently becomes pregnant. The bartender then goes forward 9 months,kidnaps the baby girl from the hospital and drops off the baby in an orphanage back in 1945.Then the bartender drops off the thoroughly confused drifter in 1985,to enlist in the time travelers corps.The drifter eventually gets his life together ,becomes a respected and elderly member of the time travelers corps,and then disguise himself as a bartender and has his most difficult missions:a date with destiny,meeting a certain drifter at Pop's Place in 1970. Now, the question is-who is Jane's mother,father,grandfather,grandmother,son,daughter?? the girl,the drifter and the bartender are the same persons,if you observed. This is the most mind boggling and cleverly formulated paradox on time travel. However the mystery yet remains the same whether we can change the past or not? and it can only be solved after traveling through time.
The post is about the progress in our understanding of time and the possibilities of time travel in our modern world.The effort is to provide the basic idea without the rigorous mathematics and terms.
So,in previous post we came to know that the space which we see as nothing is actually effected by the presence of mass or energy.Greater mass means greater will be the warping of space and since gravity is nothing but this curvature of space so greater will be the gravity...it is an effect originated from the curved geometry of space.
Heavy mass--->more warping of space--->strong gravity.
It can be easily realized..among planets,Jupiter is the heaviest planet in solar system..so it warps more space than other planets and hence it has the strongest gravity.Similarly Sun is more heavier than Jupiter thus it will warp more space around it therefore strong gravitational pull.
Since both space and time are linked with each other(known as space-time)the distortion in space also results in the distortion of time.Greater the warping of space slower will the passage of time.
Heavy mass--->more warping of space--->strong gravity--->slower passage of time.
While discussing time dilation of special relativity we understand that the faster we move,slower will be passage of time and also the space will be contracted.These effects(effects discussed in SPECIAL RELATIVITY) are relative i.e you,moving in car,will say people on ground are moving slowly and are contracted(since things are moving for you) while on the other hand for people on ground you are acting slowly and you along with your car have been contracted(as for them you are in motion).
Whereas the effects of general relativity are in agreement from both the observers.
For example,suppose you travel to some other region,which has a much more strong gravity than that of earth.Now,when you again look at the grand clock on earth,you will notice that the grand clock is ticking fast while your wrist watch is ticking at the normal rate.And people on earth,observing your wrist watch will say that your wrist watch have been slowed down and their grand clock is ticking normally.
Here both are saying the same thing but the other way round.
It is because when you moved to the other region with strong gravity(i.e region of more warped space).This curved space also effect your senses and since our senses along with the space have also been distorted that is why we feel everything normal in our local region...and obscure in other,non-local regions.
Such dilation in time due to the curved space is generally called gravitational time dilation.
Einstein's theory of general relativity not only tells us about the curved space-time but it also predicts two highly fascinating objects which should exist according to the theory.
First are Black holes,which have been successfully detected and the other are wormholes. BLACK HOLES are formed after a star dies crushing down completely under its own gravitational pull.They are highly dense..the neutrons and other subatomic particles are almost touching each other having no space between them.
To get an idea of the density of black holes...a ONE SPOON FULL mass of a super massive black hole will be much heavier than the mass of whole landmass of Delhi.
Since Black holes are much more massive and dense... they warp the space around them to a greater extent and hence have a very strong gravitational pull.Even light can not escape the gravitational pull of black holes if it enters the event horizon.
Event horizon is the limit beyond which if anything goes,into the black hole,then it can never came back and will be crushed by black holes immense gravity.
The first image below shows the different stages a dying star passes through to become a black hole
Now since even light can not escape their gravitational pull,they appear black. BLACK HOLES CAN BE USED TO TRAVEL FORWARD IN TIME... If you have understand gravitational time dilation(discussed above) then it will be easy to understand. Suppose you enter a space shuttle and travel close to a Black Hole...since you are now in a region of high gravity then time will pass more slowly for you than the time here on earth.After spending just few hours near to the black when you will return back to the earth then you will find that many years have been passed on earth. That is you traveled to the future spending just few hours near to black hole. However, there are no black holes present near our solar system.The nearest black hole is several light years away from earth..so just to get there requires a lot of fuel first and to spend few hours near it,without being pulled inside will require immensely powerful exhaust system..to overcome their gravity. So going to the future is possible however it may take several years to built such highly efficient ships. Now,what about going to the past?? This is achieved by the wormholes described by general relativity.
Wormholes are just like the tunnels connecting two different places with each other...wormholes also connect different regions of space in our universe.A wormhole simply cut short the distance between two regions of space.Since they are bridges connecting two regions so there can be different kinds of wormholes,some connecting two regions in same universe or some connecting two different universe(if multiverse exist). Wormholes are also supposed to connect different times as well. That is if you enter a wormhole you not only be transferred to an other place but also to either to future or to the past as well.
All this seems exciting right? But sad part is that no macro wormholes(macro here denotes big enough so that spaceships can enter it) have never been detected so far.And if they are detected in future then the physics underlying them states that they will be very unstable.So much sensitive that if anything will cause any disturbance,they will collapse..closing forever. But in June 1988,three physicist Kip Thorne,Michael Morris and Ulvi Yurtsever 'solve' for a womhole (solve because wormholes are predicted mathematically by general relativity,they don't have any physical existence yet but they are supposed to exist),one which is stable and can be used to travel. So it may be possible that one day these wormholes were detected and our technology become so advance that we can construct efficient ships to travel close to a black hole and to pass through wormholes. So whatever you see in science fiction movies are often valid theoretical possibilities off physics which are yet to be verified experimentally. Now it's all folk regarding the time travel..Time travel is not possible with today's technology but may be in a distant future it may becomes the reality. So,if we happened to travel back in time..can we change the past?overturned history completely?rectify our mistakes done in past?....in next post.
