ELIF: how is time relative?
In: Physics
The speed of light is constant (in a constant medium).
If we were able to be an observer on an object traveling at half the speed of light and we were to turn on a flashlight in the direction we were going, it would appear that the light traveled away from us at the speed of light. We might assume that to a stationary observer the light leaving the flashlight would appear to travel at 1.5 times the speed of light. But this would be impossible because the speed of light is constant and can’t be exceeded.
The thing that has to alter to keep the speed of that light constant for all observers is time. Our time would pass differently than the time of the stationary observer.
