You can time travel in two ways.
You can go to the past or you can go to the future.The interesting thing is that people have already traveled to the future.Traveling in the past can be difficult.New research has revealed that time travel is not only possible but also safe for humans.The question is, do you want to time travel?
Commonly associated with time travel are speed, space, and gravity.From the general theory of relativity, we can learn about the prolongation of time. For example, 1 second is a different amount of time for a person standing on Earth and traveling at close to the speed of light, or 1 second for a person traveling around a black hole. We still don’t have the technology to travel at the speed of light.This is how time works according to science and mathematics.
Since time travelers are orbiting our planet at 17130 miles per hour, we can easily observe time travel.You may ask, Where are these intrepid travelers?The answer is the International Space Station.The crew members of the International Space Station are traveling over your head at the moment.They travel in both space and time.This is because they move faster than we do on Earth.A man moves as slowly as he moves.So the way time is going for us, time is going a little slower than for astronauts in space.
Scott and Mark Kelly are NASA astronauts.They both are same.Scott was in space for 524 days, while Mark was only 54 days. They were both born six minutes later on this day.But Scott stays high in space for a long time, so technically, Scott is 5 milliseconds shorter than his twin brother.Mark, on the other hand, can be assumed to have traveled into the future in 5 milliseconds.5 milliseconds is a very short time. Triumph travel is not only possible, those who have once reached space have at least time traveled.A significant amount of time travel is not possible with the speed at which our spacecraft run.But that might not always be the case.If you can be an astronaut in a spacecraft whose velocity is 99.999% of the speed of light, you can travel a significant amount of time into the future.If you travel at this speed, 1 second on earth is 20 hours for you. That is, if you travel at the speed of light for one day and return to Earth, then your age will increase by one day, but 72,000 days will pass on Earth.We can say that you have time traveled 197 years into the future.With the development of technology, time travel is theoretically possible.
Although time travel in the future was not so complicated, time travel in the past was much more complicated.If we look closely, the more we look at the sky, the less time we travel on our own. Since everything in space is far away from us, it takes a long time for light to reach us from there.That is, when we look at the stars, we actually see the stars of the past.We see the stars at the moment when the light is emitted from the stars, but it takes a long time for the light to reach us.This could be millions of years.As an example, we can take the North Star, also called Polaris, which is located in the very center of our galaxy.Polaris is 323 light-years away from our planet. When someone observes Polaris from Earth with a telescope, he can actually see 323 light years in the past. Even if Polaris is destroyed at this moment, we will know it in the next 323 light years.Now if you want to time travel closer, you just have to look at the moon.When you look at the moon, you can see the moon about 1 second earlier because it takes 1.3 seconds for the light from the moon to reflect back to our eyes.
It is not difficult to see the past, but to travel to the past is another matter.A wormhole could be a way to time travel into the past.
A wormhole is like a tunnel between two distant points in our universe that shortens the travel time from one point to another. Instead of traveling millions of years from one galaxy to another, under the right conditions, one could theoretically reduce the travel time to hours or minutes by using a wormhole.Imagine a wormhole with a tunnel through one of the tunnel doors
By entering and exiting through another door, we can time travel into the past. We have some problems in trawling through wormholes, firstly we have not found any wormhole yet, secondly we have no idea what can happen inside the wormhole.
In the past, no method of time travel has been invented yet, but scientists are researching it. Another confusion people have about time travel is the paradox.
Let’s assume that all the technical, theoretical problems are solved and time travel to the past. There’s an interesting paradox. This is the Grandfather Paradox.The thing is, you time-traveled into the past and killed your grandfather. If your father died before you were born, how could you be born? You were never born.How’s that possible?
Then you can never go to the past and kill your grandfather. Because of such paradoxes, many people believe that time travel is not possible in the past.
Recently, researchers have explained the paradox in a new way, saying that if such a paradox really happened as a result of time travel, the universe itself would solve it.For example, you went to the past and killed your grandfather. But the truth is that the person you killed was not your grandfather. Maybe you’re an adopted child and never knew it.
Time travel in the future is easy, you just have to move very fast. Time travel in the past still has many problems to solve and requires many advanced technologies.
