Time travel has been a fascination for people since the dawn of civilization. It has been a topic of science fiction for centuries, but is it really possible? According to NASA, time travel is possible, just not in the way you might expect.
Albert Einstein’s theory of relativity says time and motion are relative to each other, and nothing can go faster than the speed of light, which is 186,000 miles per second. Time travel happens through what’s called “time dilation.” Time dilation is when time passes more slowly for one observer than it does for another. This means that if you were to travel at the speed of light, time would pass more slowly for you than it would for someone who is not moving.
This means that if you were to travel at the speed of light, you could theoretically travel into the future. For example, if you were to travel at the speed of light for one year, you would arrive at your destination one year in the future. This is because time is passing more slowly for you than it is for the people who are not moving.
However, traveling at the speed of light is impossible for humans. We can only travel at a fraction of the speed of light, which means that we can only travel a fraction of the time into the future. For example, if you were to travel at the speed of light for one year, you would only arrive at your destination a few seconds into the future.
There are other ways to travel through time as well. One way is to use a wormhole, which is a theoretical tunnel through space-time. If you were to enter a wormhole, you could theoretically travel to any point in time. However, wormholes are also impossible for humans to create.
Time travel is also possible through time machines. Time machines are theoretical devices that allow you to travel to any point in time. However, these devices are also impossible for humans to create.
So, is it possible to travel through time? According to NASA, the answer is yes, but it is not possible for humans to do so. Time travel is possible through time dilation, wormholes, and time machines, but these are all theoretical devices that are impossible for humans to create. Therefore, while time travel is possible, it is not possible for humans to do so.
