Time travel, a dream come true fantasy for the young generation, but can it really be true?. We have seen all times of time travel machines, all the dark matter stuff, but is the matter true. Some studies show that time traveling is possible but only theoretically. Many scientists have made their researches and one of them is Albert Einstein. The idea of the time machine was made popular by a famous writer H. G Wells which made the young generation crazy. Time traveling is theoretically possible by breaking a parameter that is traveling faster than light which is impossible as of now. Albert Einstein a famous scientist came up with the concept of time. According to him space and time are linked together and our universe has a speed limit that is speed limit. So to time travel, there should be something that can break the barrier of the light speed.
Time is actually the fourth dimension. Einstein’s theory of special relativity says that time slows down or speeds up depending on how fast you move relative to something else. Following the concept of speed of light, a person inside a spaceship would age much slower than on earth. There are many movies featuring the concept of speed of light on a different basis. Movies like the interstellar, doctor who, and much more. As an object travels the speed of light, its mass rises quickly. If an object tries to travel 300000 kilometers per second, its mass becomes infinite, and so does the energy required to move it. For this reason, no normal object can travel as fast or faster than the speed of light. Another tern for time travel is the wormhole. A wormhole can be called as a tunnel with two ends at separate points in spacetime. Wormhole connects the two points. Generally, for time travel one end of the wormhole has to be accelerated to a certain fraction of speed of light and then bringing back to the point of origin. So hypothetically we can travel time but still, there is no such machine made for time travel.
