People think of time as an object in which you can move forward or backward with the help of science.They say time is the fourth dimension.But what time really is .
before starting to explain my point I would like to remind you the following facts about world as explained by scientist community.
1.Nothing could be destroyed in this world.Every thing that exist simply changes it`s form and final state of this conversion is energy which also can not be destroyed.
2.Nothing is stable in the universe.Earth and all stars are moving as we speak or do any thing and this shift never stops.
Now let me give you an example of year 1942.No you can not find it in history books nor you can google it so just read the following.

There was a man in India who used to make columns with bricks.So in the summer of 1942 he used 10 bricks named A,B,C,D,E,F,G,H,I and J. Then his son after his death demolished this column and re created it next to his grave where it stand today .Now the only problem is that he placed the bricks in a random sequence and did not followed the sequence of his father.Generations after generations these bricks were used in all possible combination .
Now today if his grand son wants to see the brick column made by his grandfather,what he has to do ?
Option one : He should go to the room in the back where he keep all the old stuff.Find the old photo album of his grand father and take out the picture of the grand father with his creation.
Option two : Get back in time..........
But getting back in the past is not that simple task.No , I`m not talking about the Grandfather Paradox.His grand son can follow these simple steps to get back in the past.
1.Calculate the earth`s exact position in the summer of 1942 in the universe as today`s Earth might have traveled trillions of miles in space from that point of universe.
2.Give back the Sun all the Hydrogen it has burnt since 1942.
3.Find and recollect the uncountable particles of every thing that existed in 1942 which are now re-positioned in this universe by nature and put them back in their place.
Past was just a different combination of this bricks and present is a different combination of the same bricks from the past. And a new combination of these same bricks will made our future.
The whole world is just made out of these 3 bricks we call basic particles called - electron , proton , neutron
So can you calculate the right position of these uncountable micro bricks.No one can....because there is no past ....it was a previous stage , an old combination and there is no future to travel as it has not made yet.There is just present....We are going in our future as these particles change their places and convert things in their next form.
Now let us take the argument that says...travel with the speed of light and you can get back in to the past or future.....
Now answer me a question . What is the answer of this statement 1-1=?
The answer is 0
Yes...it is the right answer and you know what even when you travel with the speed of light you only take with you those particles which are used in creating you and your machine.Rest of the particles are still changing their place but at a normal speed.So go ahead if you want to travel with the speed of light ...bye bye...rest of us will meet you in the future...but you know what will happen..when you get off from your ride it has brought you at a point of the universe where Earth still have to reach in next few 100 years.And when you stop traveling at the speed of light your particles again get their older speed of change.Now are you ready to wait till next 100 years to wait for us to reach you .you`ll be old.
The so called time ( The process of constant replacement of particles) never stops , never pauses nor it speeds up.
So what is the moral of this story...???
These is no past and there is no future...every thing you had is this moment ...the future of your past and the past of your future THE PRESENT.Live it , like it ....love it...and yes ! If you want to change your future start working for it today....!!!!
