What happens when a spaceship traveling the speed of light turns on its headlights? :-)
LMAO!! OH now that is great!!
That’s tight up there with, why do they call it hemorrhoids and not asteroids?
First, a spaceship with mass can NOT move “at the speed of light”. Its mass approaches infinity as it approaches the speed of light. Only massless “things” can go the speed of light.
When it is going as fast as it can, and turns on its lights, it observes the light flying away from it at the speed of light. A “stationary” observer in front of him ALSO would measure the light traveling toward him at c, “the speed of light”. An observer “behind” the ship would ALSO see the beam of light progressing away from him at c. All of this due to the “curvature of space-time”.
Weird, but borne up by many experiments in particle accelerators and particle colliders.
