Is Time Travel possible?
Albert Einstein found out that if a person is able to travel at a very high speed, time will be slowed down for him. You know that nothing in this universe travels faster than light, right? So, travelling at a speed close to the speed of light would make time run slow for these travellers.
What if you traveled faster than the Speed of Light?
Let’s imagine what would happen if there is a spaceship that can travel at the speed of light and you go into the space riding it for five years. For you, time will pass slowly though you will feel that it is running at its normal speed.
According to the calendar on your spaceship, you will only be out for 5 years, but, according to a rough estimate of the scientists, more than 50 years would have passed on the Earth.
Upon returning, you would be truly astounded to see the changes that would have taken place on the Earth. Your teachers would have retired, your friends would have grown old and your city might have changed beyond recognition!
What is a Wormhole?
In 1935, Albert Einstein proposed the existence of ‘bridges’ or ‘shortcuts’ in space. He coined a unique name for these bridges or shortcuts—wormholes. Wormholes are supposed to connect two different points in space and reduce the travel time and distance, thereby making time travel a possibility.
Why have we not started time travelling yet?
All these concepts of time travelling and wormholes are still in their infancy. Also, our scientists have so far not been able to invent a super-fast ‘time machine’ that could travel at the speed of light. However, that doesn’t mean it is completely impossible. We’ll just have to wait and watch; only ‘time’ will tell the truth about itself.
