Hello and welcome to part 3 of my unanswerable questions.
So far wev tackled the noise a giraffe makes and wondered about the nose of a truth telling Pinocchio, and today we want to know —-
What would happen if you were traveling at the speed of light (or maybe faster for a different answer) and turned your headlights on?
God speed x |

The same thing that happens when you're in a jet that breaks the sound barrier... nothing.
You'd be travelling faster than light, so you wouldn't see any light  |

If I was travelling at the speed of light and turned my headlights on I’d probably loose my panties due to the gravitational pull of the light light emitting diode particles as the flash past my ass taking the very fabric of life with them |

If traveling at exactly the speed of light I'd suspect there would be some sort of build up of light waves. Similar to that seen when breaking the sound barrier.
If traveling faster than the speed of light I'd suspect You'd leave a trail of light behind you. |

"The light would still move away from you at the speed of light. The speed yup are travelling doesn't have any effect."
Then why don't you hear a sonic boom when you break the sound barrier?  |

Due to you travelling faster than light and us needing light to See, whatever happened you wouldn't be able to see anything as though plenty of light would be hitting your eyes it wouldn't have time to bounce off anything around you |

It's basic physics, travelling faster than the speed of sound generates a shock wave which creates the boom. Inside the cockpit the air is stationary, no shockwave means no boom. |

You'd be in a pressurised vessel so I assume the same thing would happen as in faster than sound travel and the light / sound within the 'ship' would still be seen / heard. You'd also have light coming at you from the front/sides. So...

Light is a constant. One speed from any perspective. It governs our reality. That’s the reason you cannot travel faster than the speed of light according to the laws of physics we know about this universe. |

Einstein covered this. The speed of light is the same for all observers. The speed of light is in effect the universes speed limit. It's denoted by 'c'.
Therefore, if you shine a light in space attached to a craft travelling at 100mph the light doesn't travel at 100mph + c, it just moves at c the same as if the light is stationary. |
