What is the secret to moving through time?

The secret to moving through time, as often portrayed in Science Fiction, lies in concepts like wormholes, time dilation, and theoretical physics. According to Einstein's theory of relativity, time is not a constant and can be affected by speed and gravity, allowing for relative time travel effects. However, in reality, we can only experience time linearly and cannot travel backward or forward at will. The true "secret" remains a tantalizing mystery at the intersection of science and imagination.
