Brief description:

When you move fast, you see the world differently: time slows down like "molasses" and objects appear closer. Not that you notice the difference yourself: your heart still beats normally and don't feel any pain. What changes is how you (fast) and another person (still) see the world. That's when you both have to call in special relativity. Relativistic effects bring up many uncanny effects, yet the key to measure time with astonishing precision and guide you through the traffic using the GPS integrated into your phone.
