Time travel is a concept which is discussed every day. But very few people have correct information about it. People believe what they hear or trust films and accept the things shown in them as true. Scientists and the general public also have their own opinion on time travel. So today we are going to tell you about both, after which you will understand for yourself whether time travel is possible or not.
Under News18 Hindi series Ajab-Gajab Knowledge, we bring for you such facts related to the country and the world which can surprise anyone. Today we are talking about time travel (Can we do time travel). Some time ago on the social media platform Quora, a user asked – Is time travel possible? So let us first tell you what people replied to this.
What answers did people give on Quora?
Achintya Kumar Mishra said- “In a way…we all know that we can see any object because the light falling on that object falls into our eyes. Suppose you start moving faster than the speed of light, then after some time you will overtake the light that had come before you and you will reach near the light that came before you. “This means you will be traveling back in time.” A user named Pritam Paul said- “Yes, perhaps time travel has been happening for the last many years. There are many such incidents mentioned in history which make us believe that time travel has become possible.”
Is time travel possible?
These are the answers of common people, let us now see what science says about it. According to the report of NASA website, time travel is possible to some extent, but as it is shown in films that people go back many years in time or go ahead many years, it is not possible. Einstein gave the theory of relativity, according to which time and space are related to each other. He also said that nothing in the world can go faster than the speed of light. According to his theory, the faster a person walks, the slower time will become. That is, slightly less than the speed of one second per second. Scientists have also conducted some experiments, in which this claim is considered correct. However, it is not possible that by making a time machine a person can go back or forward hundreds of years in time, this can happen only in films. A big experiment was done by installing a clock on the plane. Two watches were taken in this experiment. The time of both was combined and one was put on the plane and the other was kept on the ground. The clock of the plane which was circling the earth was a few microseconds behind.
