Scientists have announced that time travel is theoretically possible and that people have already done so.
Time travelhas been one of the indispensable subjects of science fiction stories for years. However, it is now a scientific reality. Scientists proved the existence of physical principles that affect the flow of time and said that people experience this phenomenon. However, these journeys, unfortunately, do not include dramatic teleportation to the past or the future, like in cinema.
Time Travel Theory and Evidence
The basis for understanding time travel was laid with the special theory of relativity developed by Albert Einstein in 1905. This theory argues that the flow rate of time can change with a person’s environment and movement speed. Simply put it, the faster you move, the slower you will experience time.
This theory was confirmed in 1971 by an experiment by Joseph Hafele and Richard Keating. Scientists carried four precise atomic clocks on two different aircraft, and planes were opposed to the direction of the world’s return and in the same direction. As a result, the watches on the plane made different time measurements according to the hours on the ground. This was a proof of the phenomenon called time expansion.
Similarly, it was observed that the Astronaut Scott Kelly had aged a little more slowly than his twin brother Mark Kelly, during his time at the International Space Station. This is explained when a high -speed moving person experiences a slower time passing.
Although these findings are exciting, the real -life practices of time journey are far from the dramatic events we see in the films. According to NASA, all of us are already “traveling in time,” but only seconds in seconds. For a larger time travel, it is necessary to move at a speed close to the speed of light, which is not possible with the current technology.
Scientists acknowledge that theoretically acknowledged that time travel is possible, but more research needs to be done to make this concept applicable to daily life. For now, the idea of time travel continues to create excitement in the scientific world. These discoveries may be a pointer that bigger steps can be taken in the future.
