Theory of relativity | What is time travel and is time travel possible? Hi guys!! I am doing good and hope the same for you. Time travel is a fascinating topic, and everyone wants to learn about it. You can get many articles related to time travel, but they are challenging to understand by an ordinary person because that contains a large number of confusing scientific principles.
So, I have written an article on the Theory of relativity | What is time travel and is time travel possible? in the simplified form, which can be easily understood by everyone even he has very less knowledge about science.

What is the time? Is time constant for everybody?
“According to Albert Einstein, “time is an illusion; it is relative — it can vary for different observers depending on your speed through space. To Einstein, time is the “fourth dimension.” Space is described as a three-dimensional arena”.– Albert Einstein
Many people think that time is constant, but that’s not true. Time varies for different people because it depends on the speed of the moving body. Time slows down with the increase in rate and becomes faster with the decrease in the speed of a moving body.
What are the time travel and the theory of relativity?
Time travel is a complex concept, but you can get into it through this simplified article. Time travel means traveling through time back into your past or forward into the future. You might have seen time machine in fiction movies or cartoon serials.
Everyone knows about the famous scientist Albert Einstein. Time travel is based on Einstein’s theory of relativity.
Einstein’s theory of relativity states that time changes with the change in the speed of the moving body. It means if any person or body or a thing travels at the speed of light from one place to another, time becomes slower for that person or a thing.
For example: If a 15 years old boy travels from a particular place at a speed of light for five years and returns to that place. His new age would be 20 years, but he will notice that his friends or relatives of the same period have turned 65. He would have spent five years, but others would have spent 50 years. Similarly, a person inside a spaceship would age much slower than his twin at home. I know it’s confusing and difficult to understand. Just read it twice or thrice until and unless you know it.
Is time travel possible?
We have studied enough about time travel and the theory of relativity, but the question arises in everyone’s mind, is time travel possible?
The answer, for now, is no. The problem which arises is the speed of light. The person needs to travel at the speed of light that is 299,792,458 m/s. It’s very difficult or almost impossible to go at the speed of light till now, but scientists are researching and investigating on time travel and will soon find a solution to travel time. Any person or even spaceship cannot move at the speed of light, but If that would be possible, it will require a very large or almost infinite amount of energy. So, time travel is not feasible for now, but I hope it would be soon.
