I'm sitting in a spaceship that flies at the speed of light. I turn on the flashlight in the direction of the starship. What is the speed of light from a flashlight?
The speed of light from a flashlight is the speed of light.
Like when the Americans landed on the moon and televised it. It took a second and a half to get from the moon to the Earth as the distance is about 240,000 miles.
Now a question for you Ivan. How long did it take the video signal from the Russians that landed on the moon?
