- TL;DR Summary
- Assumption travelling at speed of light is possible.
1. We are in empty space. I am travelling backwards(I am facing the direction opposite to my direction of motion) at half the speed of light. My other friend is travelling in opposite direction with the same speed being backward. If i look in the direction of my friend, i will see him getting slower and slower as we move apart even though relative velocity between us is still the same.
Time as we perceive is not a universal constant. It depends on the speed of the bodies and the distance between them.
