Speed Of Light Question?

Question

Imagine you are in a vehicle travelling at the speed of light.
You turn your headlights on.
Does anything happen?

Answer 1

LOL Doug

1. You cannot go at the speed of light. YOU JUST CAN'T so there is no point hypothesizing about it.

2. If you were, then your mass would be infinite. So you would exert infinite gravitational force on the universe, sucking everything into your little personnal black hole.

3. If you were, distances in your forward direction would shrink no 0, and time would stop. So in effect you would be everywhere on your trajectory at the same time and that would be the only time you would experience. For you, the universe would be an eternally unchanging 2d plane.

I can keep going with all sort of funky impossible effects, with a lot of nasty mortal ones (your heart stopped, your blood congealed a long time before reaching speed of light)... but it is pointless, YOU CANNOT REACH THE SPEED OF LIGHT! EVER!! Even if one day we find a way to exceed it, we will have to go from less than FTL to more than FTL in an instant without EVER REACHING THE SPEED OF LIGHT!

Answer 2

If you are traveling at the speed of light, the headlights would be traveling at the same rate, which means they wouldn't be traveling faster than you. Headlights are supposed to go faster than a car so they can reach the destination faster than the car at night, which is why we can see the lights in front of us. But if the headlights and the vehicle are traveling at the same rate, they would reach the destination at the same time. Technically, the headlights would still do something, but there would be no benefit to the person turning the headlights on. It would have no effect.

Answer 3

You're traveling at over 186,000 miles per second. When you turn on the headlights they go on. But, the light beam won't be able to accelerate fast enough to escape the bulb. So, if you were looking at the headlight, you would see light inside the bulb. It would be similar to going 100 miles per hour in a car and trying to throw a baseball forward. Although, there is less resistance and no gravity in space , the light would need to travel faster than itself to go beyond the bulb. This in all "in theory".

Answer 4

good adequate. Time does no longer circulate slower for speedy gadgets. plainly to you, assuming you are going to be table sure, that element is passing slower for speedy gadgets. If there are not any accelerations reward - each thing is often shifting on the equivalent speeds relative to a minimum of one yet another - then there is not any thank you to tell who's moving and who's at rest. Now the twin paradox, which you sort of paraphrased right here, has 3 accelerations in it. you start up from entertainment and accomplish an extremely extreme speed. After a time, you turn around this suggests which you sluggish down, you momentarily quit, and you speed as much as a extreme speed back. subsequently you attain earth and sluggish to a stop. At each and each acceleration, you adventure a force which the earthbound guy or woman would not so it rather is sparkling who's in flow and who's at rest. subsequently, you are going to return after 10 years some time maximum effective to seek for out that a plenty longer time has handed on the planet. Now star trek assumes there is a thank you to adventure exterior of the 4 dimensional area that defines the universe - the so-properly-referred to as subspace. in this subspace, relativity would not stick to - that's exterior the universe incredibly plenty - so which you will desire to circulate from element to ingredient in a finite quantity of time and, the time it takes to traverse the hollow as measured by way of the starship's clock may be the time that elapses interior the universe - sort of no longer likely in spite of the indisputable fact that crucial while you're writting one hour long television episodes. there is not any information for the kind of holiday use in standard guy or woman trek.

Answer 5

Lets assume that its possible. (It really is not) but anyhow for the fun of it here is what happens, the headlight beams stream forward at the exact speed of light.

The speed of light is a constant and independent of the motion of the source. That is true always so the beams shoot out at speed of light, not double the speed of light. Quite different from sound in which the source is additive to the sound wave.

Answer 6

If you are travelling at the speed of light, the time stops for you, from the perspective of an external observer. So you never turn on the light.

To Hannah C: this question gets asked on average once every day...

Answer 7

It is impossible to travel at the speed of light but It is possible to travel at 99.9999999% the speed of light. If you were traveling at this speed and turned on your lights, light would travel away from you at the same speed as if you were stopped. Light always travels away from you at the same speed. Light does not move through an either it moves relative to you. The Michelson Morley experiment proved this.

Answer 8

A similar question was actually addressed by Einstein in his work on the theory of relativity. His problem was posed as such: suppose you are travelling at the speed of light and you held a mirror in front of your face. What would you see, and what would an observer see?

His answer was this. Relative to yourself, you are at rest, so the light from your face would reflect off the mirror at the speed of light and you would see your reflection. If an observer was somehow able to watch, however, he/she would NOT be able to see your reflection, as from his/her frame of reference, you are travelling just as fast as the light from your face to hit the mirror.

Answer 9

No matter who observes it, no matter the motion of the observer, no matter the motion of the source of the light, the oberserver will always measure a photon's speed as "c", or the spped of light [in a vacuum]. Time dilates, distance or space warps, but the speed of light is always constant.

Answer 10

No, because your car and the light both travel at the speed of light, you will not ever see the light, because it will appear to have never left the headlights.
