How can speed of light constant for moving and stationary source in vaccum?
That's fascinating! Can you give me an example of how space and time adjust to maintain the constancy of the speed of light?
Sure! Let's say you're observing a beam of light while standing still, and I'm observing the same beam of light while moving towards the light source at half the speed of light. From my perspective, the beam of light appears to be approaching me at the speed of light, just as it does from your perspective. However, since I'm moving towards the light source, time appears to be slowed down for me compared to you. This means that even though the beam of light is approaching both of us at the same speed, I perceive time as being slower than you, so I observe the distance between us to be shorter than you do. This adjustment maintains the constancy of the speed of light.
