Time travel was never considered possible but the urge to meet a departed loved one again, to be able to have a chance to make things right again, and to be able to experience the thrill, people have always considered time travel as a possibility. Since centuries, scientists and researchers have debated on whether it is possible to manipulate time? To manipulate it as per our will? We still don't have the answer to all the questions but it's a topic that the believers are not ready to give up on. When it comes to traveling through time, there are a lot of things going in our minds, things like can be beat the speed of light and travel faster that it? Or is it possible to create a machine that can take us from one point in space to another point at an instant? For the scientists who believe time travel is possible, their answer is yes. As absurd as it may sound but according to them, time travel is actually possible, we just have to find out how.

At present, the most acceptable and logical way of traveling through time is considered to be through a black hole. The idea is to go around a black hole at speed nearly equal to the speed of light and orbit outside the black hole barely to not get caught in it's gravitational field. Once it's done, and we return to the earth, we would have barely aged but the world will change, we will step into the future and things will not be the same anymore. The most famous example of this theory is the twin brother example, consider two twins, both are 20 years old, one of the twin goes inside the space-ship to orbit the black hole while the other one stays back on earth. Now for the twin inside the space-ship, time will flow slowly because of a phenomenon called time dilation, which means that the faster an object goes through space, lesser is the time that will pass, while on earth time will pass normally. When the twin in the space-ship comes back to earth after orbiting the black-hole for 5 years, he will age 25 years but when it comes to the twin who stayed back on the earth, he will now be 65 years old and most of his friends would have already died, the world would have changed.

But as good as it sounds, this method has many flaws, the first one being that in order to fuel a space-ship that powerful let alone create it, it will take mankind a lot more than it can offer. We don't have the required technology or the needed knowledge in order to create a space-ship powerful enough to make it orbit a black hole at speeds nearly equal to that of light. Despite all this, time travel still remains a possibility and scientists still believe that there is a "different world" waiting for us on the other side.
