If you are driving your space ship at the speed of light and then turn on your head lights, what happens?

Answer 1

Michelson and Morley demonstrated that the velocity of light in a vacuum is measured as constant by all observers, regardless of the motion of the light source or of the observer. This is contrary to our everyday experience: if a passenger on a train moving at velocity X walks forward (in the direction of the train's motion) at velocity Y (relative to the train), then a seated passenger on the train will measure the person's velocity at Y, while an observer on the ground will measure the walker's velocity at X + Y.

But if the walker points a flashlight forward and turns it on, the walker, a seated passenger on the train, and an observer on the ground will all measure the velocity of the light beam as c (the conventional symbol for the speed of light in a vacuum, about 299,792 km/sec).

Albert Einstein expanded on the Michelson-Morley experiment when he published his special theory of relativity in 1905. It postulates that the mass of an object with a non-zero rest mass will increase as it moves faster, asymptotically approaching infinity as the object's speed approaches c. So you can't move your space ship at the speed of light unless it has no rest mass, and if it has no rest mass then you can't move it at any other speed.

If you move your space ship at (say) 99.9% of c and turn on the headlights, you will measure the light beam moving away from your ship at speed c, not at speed 0.1% of c. A stationary observer (meaning for this purpose one who measures your space ship moving at 99.9% of c) will also measure the light beam moving at speed c relative to the observer, but to the observer, since you're moving at 99.9% of c, the light beam will appear to move away from your spaceship at speed 0.1% of c.

Answer 2

A space ship can't go the speed of light. If an atom is accelerated to 0.99 the speed of light and it emits a photon, the photon will travel at the speed of light away from the atom. Anyone in the laboratory will see the photon traveling at the speed of light. This seems contradictory until you include time in the equations. The observation from the atom's point of view and the observation from the laboratory's point of view aren't in the same time frame.

Answer 3

Nothing. The light can't move faster than your ship, which is already going at light speed. But you wouldn't notice anyway, since time stops if you're going at that speed.

Answer 4

Headlights on a spaceship? Ooookaaayyy.... while you're in a jet shifting at (or above) the fee of sound and somebody talks to you, do you pay attention them? There ya pass. The headlights could paintings only high quality and lightweight up something interior the instant area that grow to be vacationing at a velocity relative on your guy or woman. yet you in all probability would not see plenty in case you grew to become on the headlights of the Starship Chevrolet, if purely using fact there is beneficial little in area to be certain. If there grow to be some thing close sufficient to be certain with headlights, you may in all probability be at sublight velocity and docking with it.

Answer 5

The speed of light is RELATIVE to the observer (you) so the lights would switch on.
Yes, it doesn't make sense but we aren't as clever as Einstein and he says that's what would happen.

Answer 6

if u are traveling at light speed you and your ship would turn into pure energy

Answer 7

You would still have no light. The light would stay right in the lamp of the headlight.

Answer 8

nothing

or if ur lucky

u got a spacecraft with lights on

Answer 9

dude trust me. if your traveling at the speed of lite your not going to need headlites

Answer 10

Nothing. Moot point.
