D you ever think time travel is possible like Movies, Cartoons?

Updated: May 24

If we think about time traveling we will think about time travel going beyond our past or future using a time machine. Also, we will think that we are traveling at light speed and faster than one second. This can be true or not. How these can be implemented into reality. Till now no one knows how to make it into reality. But Science says it's possible. These kinds of time travel actually we see in movies, series, and books only.


Then, how possible time travel?

Time travel is possible under certain conditions and it is possible to experience time passing at a different rate than one second per second. Humans currently don't have anything for time travel and we can't hope for a time machine someone will develop future.


Many years before Albert Einstein came up with an idea known as relativity. This relativity helps us a lot to understand how time works. This theory suggested that space and time are linked together, our universe has a speed limit and nothing can travel faster than the speed of light i.e. 186000 miles per second. Gravity curves space and time causing the passage of time to slow down.


Then you have a question in your mind how is this theory helping us with time travel. If we understand this theory we will get that the faster we travel, we will experience slower time.


Is there any proof? Science proved these experiments. The answer is yes.


Let's take an example, take two clocks and set the same time. Put that one clock in earth and keep another one in a flying airplane traveling in the same direction that the Earth clock rotates. After that, the flight flew around the world, and scientists compared both two clocks. The result was shocking because the clock on the airplane was traveling slightly slower in time than 1 second per second

Are we using time traveling in everyday life?


Do you know that everyone is traveling in time, for example, we are traveling one year in between birthdays. Actually, we are traveling in time at the same speed approx one second per second. Do you know that objects including, events, an explosion in space we see through our eyes in space and telescopes, that happened a very long time ago, for example, Sunlight takes 8.4 minutes to reach our planet? That means the Sunlight we see in our eyes the light actually take place 8.4 minutes ago.


Space telescopes from different space agencies including NASA help us away look back at that time with the help of Space Telescopes deployed above the Earth. These Space telescopes help us to look at distant faraway objects beyond the Earth in space. As we mentioned earlier that the galaxies, stars, planets we see looked that we saw it looked like a very long time ago.


Now we won't understand the reality that time travel is possible but we cannot go to the past or future, we cannot change them or interfere with them. That kind of thing happens in movies, books, and animations only. The mathematics of time travel does affect the things we use in everyday life, for example, using GPS to navigate places and reach our destination and you want to know that this GPS relies on time travel calculations and it will help you reach your destination places.


Do you know that NASA also uses a highly accurate version of GPS for tracking satellites in space? The GPS satellites orbit around Earth very quickly and they were orbiting around the Earth at the speed of 8,700 miles (14,000 kilometers) per hour and this helps to slow down GPS satellite clocks by a small fraction of a second.


The satellites orbiting around the Earth are 12,550 miles (20,200 km) above the surface and this actually speeds up GPS satellite clocks by a slighter larger fraction of a second. When we high up where the satellites orbit and the Earth's gravity is much weaker. This causes the clocks on GPS satellites to run faster than clocks on the ground on Earth and this is not pretty good also.


The combined result along with the earlier airplane, ground clocks experiment that the clocks on GPS satellites experience time at a rate slightly faster than 1 second per second, and scientists can use mathematics to correct these differences in time or else there is a problem that if scientists are not able to correct the GPS clocks, GPS not able to locate your position or their position. The errors would add up to a few miles away each day and scientists correct them.
