Speed of Light is ~300,000 KM/Sec.
It is said that nothing travels faster than light. And, Light speed is independent of the speed of the emitter.
Consider a situation like:
- Imagine Person-A is in Vehicle-A, and Person-B is in Vehicle-B. Vehicle-A and Vehicle-B traveling in space, side-by-side. Each person directs a torch-light towards other.
Questions:
- Q1. Can they ever see each other, if they are traveling at speed-of-light?
- Q2. If they are separated by 300,000KM, and stationary (what is stationary in space?), it takes 1-second for the light from torch-light to reach other vehicle. If they are travelling at speed-of-light, will this light from torch-light ever reach other vehicle?
- Q3. Question about "Stationary": Lets say they are very very very faaaaar away from any other objects (galaxies, starts etc)... And, traveling at the speed of light, side-by-side, by 300,000KM (or say 1KM). So, essentially they are stationary to each other, because of there is no relative-motion. Shouldn't light from torch-light reach other vehicle? Can it?
