Scientific Possibility of Time Travel
Time Travel, a term known all over the world as fictions or fantasy, to travel across the fourth dimension and learn about what awaits you in the future but after you finish reading this article you would believe that such a thing is actually possible. It all began with Albert Einstein's 'Special and General Theories of Relativity'. These theories proved time to be a flowing river on which we keep walking, if we move near or close to the speed of light the river of time slows down for us allowing us to leap across the river instead of walking but if we go at the speed of light or beyond it we can go back time. For instance, if we rotate the Earth at the speed of light for one year we would go 223 years forward in time. Another interesting fact about time travel is the theory of moving clocks that Einstein stated, this theory proved that when we travel through time the clock moves slower than the usual time and as I have mentioned before, allowing you to leap across the river of time. One of the most important thing about relativity is the relation between time and space. Everything that occurs in space also occurs in time and everything that occurs in time also occurs in space so we can say time and space can’t exist without one another, the two exist as one: space-time continuum. Another thing that Einstein said was that if we moved fast enough at a point in space where the gravitational pull is very high we would benefit from a term called “Time Dilation” which means that time would slow down for that person so in turn it means that we’re travelling to the future as the time for the rest of the world is moving faster. The Philadelphia project that took place in the late 1940’s was also an example of time travel. The project's attempt was to make a naval ship disappear by the use of hyper speed and pressure. After the disappearance, the ship arrived in Norfolk, Virginia with a few of its crew members missing. The ship used was named USS Eldridge. The reasonable explanations are time travel and transportation to a parallel dimension.

COSMIC STRINGS: The possibilities of going to the future are immense as we don’t need to travel faster than light, but what about going to the past? To go there we need to reach a speed faster than the speed of light (299,788.5 Km/s) which with our current advancements in science seem impossible. But physicists have said that when the universe was created there were some string like structures weaving the entire universe but they were thinner than an atom and under immense pressure. So you might ask that how is this relative to time travel? Well, believe it or not this is what will give us the energy to travel back in time. How? See if we can pull two Cosmic Strings close to each other or a black hole their gravitational pull will give us enough energy to warp through space- time. This happens because their gravitational field allows them to boost the speed of anything passing near them to Light speed and benefit from Time Dilation. This Cosmic String was first introduced in 1991 by J.Richard Gott. He himself said that this was possible but the amount of energy required was too much it would possibly take the energy of half a galaxy to do this.

WORMHOLE: Another possibility worth exploring is the Einstein-Rosenberg Bridge or to many people known as a Wormhole. This wormhole is said to connect to points in space. How do they do that? This is how it’s said to be done, when two black holes form at the same time they connect to each other by piercing a hole through time-space and when they connect their gravity fields cancel each other out therefore stripping it of its properties of a black hole and letting enter through it at will but..... no one can surely tell where they will drop you off and as they are highly unstable they may close as soon as you are out. Now the thing is where are you? In a parallel universe, another time, another galaxy or in another universe? You can’t be sure because you are in deeps space! So to use an Einstein-Rosenberg Bridge as a time travel unit we would need to be able to control where it goes. To control it would not be as hard as we think using electromagnetic waves to attract electrons then using the very force to make them spin around so fast causing them to form a hole in the fabric of time and space, rather a shortcut to another point in the river known as time. A wormhole right now is our most possible way of time travel. And don’t get surprised when I say this that the US government has done this already!! As it has already been mentioned.

KERR RINGS: In 1963 mathematician Roy Kerr suggested that if a dying star collapsed into a ring of neutron stars it would not form a singularity therefore it wouldn’t have the immense gravitational pull that would stretch things apart instead we could enter it and come out into another time or point in the universe modern scientists speculate that he exit point would be a white hole which would push everything out instead of pulling them in. But in the case of a black hole if we circled it for the right amount of time we would be able to travel to the future by benefiting from time dilation but there’s always the danger of us falling in getting torn to pieces.

PARADOXES: Something that grabs the attention of everybody reading about time travel is the paradox theory. Us going back to the past before we were born us existing before our birth. In the river of time the effect was experienced before the cause. It’s like saying the fish in a pond died of pollutants before the water was polluted! How does that happen but here is the thing that intrigues my head since at that time we weren’t born how can we die? One thing to make the paradox as clear as water is this scenario: Think that you’re a time travelling assassin and you’re target is your own grandfather (and this was before your dad was born) so if u go to the past and you’re face to face with your grandfather you have a gun in your hand and you’re ready to fire..... you fire the gun! So now that you’re grandfather is dead your father wasn’t born so he(your father) never gave birth to you so you would never take the job as a time travelling assassin to kill him in the first place so ....confused yet. Probably there will be some malfunction with your equipment or something but your grandfather can’t die. We have explored the multiple possibilities of time travel and have come to realize that with the right amount of thinking (and the courage to perform the experiments required) time travel would be in our doorsteps. But the sad truth is that though it would help us a great deal there are always those who would use it for evil. Even the Sound Reactor in Switzerland shows a great deal and it’s proof that time travel is being researched on by many countries who are thirsty for power and the only way to quench it is the next big war and shocking as it may sound it would not be nuclear weapons this time but changing the course of history .And there have also been many signs of time travelers in the past for example “The Babushka lady” who was found on the sight of the Kennedy killing taking pictures at the right time then found pursuing the killer and these were the only times in the course of history when she was spotted she was never found again. I would say time travel has already been done.
