Rather, it means that time is relative. If we observe the clock on the airplane from the ground, time slows down in our relation. Because we’re seeing it, time is slowing down. For a person on the airplane, and the clock on the airplane, for it, time would continue to move as it did.
Theoretically speaking, if we could build a rocket, that travels at the speed of light, and you get in that rocket. You remain in that rocket for 10 years travelling at that speed. And then you return to Earth, the time that you see on earth, would be 9,000 years later.
Simply speaking, If you want to travel into the future, you can already do it now, It is scientifically possible to do so today. The only problem is that there isn’t an aircraft that travels at this speed. You can get to the speed of light. But with improvements in technology, we can build more such aircraft and spaceships that can fly faster. It would slowly become possible.
For now, Gennady Padalka, a Russian astronaut, is credited with the most time travel into the future. It’s because he remained in space the longest 879 days. And he was travelling at the speed of 28,000km/hr in space. Accordingly, he has travelled 0.02 seconds into the future. In comparison to the people on Earth, he is 0.02 seconds younger.
with which we can travel so fast that we can travel through time significantly in the future, don’t be upset. Because there’s another way of Time Dilation as laid down by Einstein. By using gravitational force.
