If, hypothetically you're in a vehicle going the speed of light, what happens when you turn on the headlights?

Question

hypothetically...

Answer 1

As soon as you turn them on, a hypothetical deer will jump out in front of you, traveling slightly slower than than the speed of light, and you will hit him just the same... ( the warning whistles for them quit working about 100,000 m/sec)...

Answer 2

According to the accepted theory:

If you're traveling at the speed of light, you must have no mass. Therefore, there would be no car.

But say it were a little below the speed of light. The velocities don't add. If you turned on the lights, they'd shine just like normal. Both you and people watching you drive by (f*cking fast by the way) would see the same light.

Answer 3

Light doesn't change speed. The speed of the light coming from a cars headlights is exactly the same as the speed of light coming from the flashlight I'm holding. Not the speed of light plus 60. The speed of light is constant.

Answer 4

The speed of light is the same regardless of the frame of reference where the measurement is made. The light from the headlights will move away from the vehicle at the speed of light.

Answer 5

You would lose your "Class 17" (Vehicles capable of speed-of-light) licence. Because turning on headlights in a vehicle while travelling at the speed of light would demonstrate a lack of sufficient intelligence for operating such a vehicle.

However, if you claim that you turned on the headlights to allow you to see your instrument panel, they might let you get away with just a warning.

Answer 6

Here is what happens:

Let's say you are going just below the speed of light (99%). You will observe the light moving forward away from you at the speed of light, because you are moving at the same speed at the reference plane.

A stationary observer would observe them moving slowly ahead of the car, so that they were moving at the speed of light (1% faster than the car).

This situation is rectified by the fact that for you, time has slowed down immensely...so the light you are seeing and the light he is seeing are still the same thing travelling at the same speed. But because you are experiencing time at a slower rate, it seems to you like that slow light is really travelling at full speed.

Answer 7

Since the car is going at the speed of light (I'm sure that guy passed me on the freeway yesterday....) your headlights are also going at the speed of light. So when you turn them on, they emit light at the speed of light from the position where they are, so their light beams would be travelling at twice the speed of light.
Hypothetically....

Answer 8

The speed of light is constant relative to the observer, so whoever was in the car would notice nothing out of the ordinary. Well, aside from the fact that you're travelling at the speed of light. Outside observers might see something rather interesting.

Answer 9

The speed of light is constant, that is to say that regardless of how fast you are going, light appears to go the same speed to and away from you. So, if you are standing still, light travels at 300,000,000 m/s, and so does it if you are walking at 3 f/s. Likewise, if you are going the speed of light, the headlights would turn on and start travelling at 300,000,000 m/s away from the car, same thing they would do if the car were travelling down the highway.

Answer 10

The lights go on and project ahead of you. The starting point is your vehicle no matter what speed you are going. So the light speed begins with your vehicle and stays ahead of you. Some genius could work it out for you mathematically.
