I’m currently reading the Outlander Series by Diana Gabaldon. My mom suggested that I read the books 10 years ago, but I have only just gotten around to it. And boy, are they addictive!!! I HIGHLY recommend them. Although be warned, they are quite sexy.
So the books deal with time travel and I thought that might be a cool topic, albeit a very hard one to talk about since there is so much we don’t know still.
|It's the TARDIS!|
With our current knowledge of physics, the most plausible way to time travel would be to slow down time. That would let us travel into the future only though.
Let’s say you’re on a space ship with a clock. If you travel on that space ship at a constant really fast speed, someone staying still out in space would think that the clock was going slower than theirs.The opposite is true too. You, on the moving ship, would think that their clock staying still was moving slower than yours. Strange, I know.
The video below shows 2 space ships sending a signal back and forth as the "clock". Think if the signal as a second if it helps. It leaves one ship, hits the mirror, and when the reflected signal gets back to the first ship, one second has passed.
What I think is even crazier is that time moves more slowly on different parts of the Earth! The closer you are to the center of gravity, the slower time goes. Scientists have proven this with really precise atomic clocks. If you put one clock at sea level and an identical one on Mount Everest, over time the clock at sea level will run slower. Mind you it’s a teeny tiny bit slower, but slower none the less.
These ideas about time moving slowly are part of the theory of Time Dilation.
Do you wish you could travel in time? If so, would you want to go forward or back? I want to go back to the 1990s. Strange, I know. And maybe into the future to when they have the technology to explore space more easily.
