The conversation between human and AI assistant.
If you switch on a torch light on a spaceship travelling at speed close to speed of light, would the torch light be travelling faster than the speed of light as observed from outside the spacecraft?
What other interesting things can you tell me about the theory of relativity?
One interesting aspect is time dilation, which means time moves slower for objects in motion relative to an observer in a stationary position. This effect becomes much more pronounced at speeds close to the speed of light. Another interesting aspect is the equivalence of mass and energy, famously represented in Einstein's equation E=mc².
