Well, A lot of us have heard about Time Machines. We have seen the concept repeatedly in hollywood movies also. But hardly anyone of us would have ever tried to understand What a Time Machine actually is or can be. Mostly we are shown in movies that a person from future goes back in time to change things that should not have happened or something similar. But i seriously doubt if Time Machine could actually make it happen.
I think Time Machine can only make you see what has happened in past but i really doubt the possibilities of changing past. Now you must be thinking what a shit i am talking about. Rite... Open your mind & think with me, what a Time Machine actually means.
How do we measure time ? We measure it with Sun & Sunlight. Light doesn't always end, it gets reflected at times & it just passes your vision ability at times. Your ability to see depends upon light. To simplify the concept i will present it with a very simple example.
Light takes approximately 8 minutes to reach earth from sun. So if a blast takes place on Sun, we on earth will get to see it 8 minutes later. That means something that happens on sun will be seen on earth when Light carrying images of that blast reaches earth 8 minutes later. If you find it difficult to understand, please read last 2 lines at least twice again.
Continuing with same example lets think further...
A blast takes place on Sun & We see it 8 minutes later on earth. Just when we get to see it, We move to Pluto at a speed higher than speed of light. We reach pluto & we get to see the same blast once again there. Same way, if we keep running at speed more than that of light, than we can at any time stop & manage to see the blast again. Also note if you run at light speed, that image will become still for you & you will only be able to see one image of the blast since next image will reach you only when you slow down. That also means that if I start running from my house to a particular place faster than light & stop after sometime, then i will see myself running towards me, simply because ability to see depends upon light & i have simply crossed the light & my images are just behind me.
Going with the same concept if we run at speed of light for 10 years starting in 2010 & we stop in year 2020, then we will be able to see in year 2020, the happenings of January 2011. & the concept is very clear in itself that we just cannot manage the happening of the event. We can only see it & the event has already taken place.
Same way, we could run at 5 times the speed of light & 10 years later we will manage to see what happened 40 years back. So now with a Time Machine you can see what actually hitler, gandhi, bhagat singh or even King Asoka did. But i dont think you can change it since the event has already taken place.
Before i end with time machine concept, i will add one more thing that could take place while using time machine. When you run/move at the speed of light or even faster than that, below given things may happen
- You may grow older at normal pace
- you may grow older at a faster pace
- you may not grow older at all. Your age may become stable
- You may put your life in reverse gear. Possibility is, when you will get out of time machine 10 years later... you will be younger by 10 or lesser years
Time machine is a fantasy, that has scientific possibilities.
