Hi friends, tin this post we will see about this very important and mind-boggling question, what time travel is and have we done it already. so, what is time travel? well, time travel is moving in time and you’re travelling time even now. but still you’re moving forward on time, for it takes time to move forward. this is called space – time. When you move faster time of you runs slower and slower so you can go to the future. Also, if you are going to a gravitational giant, time runs slower to you while others on earth might very old or some of them also dead. And now you may ask how to go to the past. Yes, there is a way to go back to the past. So that is moving faster than light but to go faster than light you have to get infinite amount of energy because you gain infinite amount of mass while travelling faster than light.
