if you were in space...............?

Question

if you were in space going the speed of light, then turned on head lights on the front of your craft. would the light still project outward, or would you never see the lights turn on?

keep in mind here, that science knows that nothing can move faster than the speed of light...

and yes i understand that scientists have moved particles faster than the speed of light in specific gases. but i am talking about the fabric of space, a almost total vaccum.

Answer 1

Good day.
Nice logic question.
First suggestion is that we are traveling as fast as speed of light and opened light from the front of my craft would not manage to pass the speed of the craft and would not project.

Second suggestion is that my space craft will accelerate the speed of the light, by ( light speed *2)= twice as the speed of light
and would project the light , and would project as normal speed of (speed of light) according the seen from my craft .
To my Logic the second suggestion is more possible.

Answer 2

when you are in a plane traveling past the speed of sound then someone talks, would you be able to hear them?

the awnser to this question is not known; according to einstein(maybee it was Newton; i get mixed up), you cant go faster than the speed of light(otherwise we would be able to go back in time, but thats a whole 'nother toppic)

****If we were to take this case with something similar(we cant use sound because sound waves can not travel in a vacuum), you would probably be able to see the similar thing****(this was a bit confusing and pointless so you may want to skip it since i wrote something similar in the next paragraph)

Say we were able to travel along the speed of light. If you had already passed the light barrier*(which im making up--see below), you would be able to see the lights.

*I made up the words light barrier. Since we are not able to travel faster than the speed of light, scientists have not made up a term for this. A sound barrier(which i based this upon, as sound and light work in similar ways)is when sound waves pile up around the plane in a cone shaped fashion(see below)
<
< <--plane
<


b c



when the plane is in that position, listener c would be listening to the planes noise; b will only be able to hear when the plane is over A(which should be in front of a but yahoo awnsers doesnt do diagrams)

this is not a very good explanation of a sound barrier; it takes many drawings and such.But i hope you understand somewhat.







hope i helped more than i confused you. Do a little research on ur own. itll help

"keep in mind here, that science knows that nothing can move faster than the speed of light..."

Science knows, huh? I'm afraid this is not true.

Here's a link to CNN's web site with the story of some researchers in Princeton, NJ, breaking the speed of light back in 2000.

My thinking would be that no, you couldn't see the lights turn on if you were somehow outside your craft and facing them and also travelling at the same velocity as your craft, the light could never reach you.

Answer 4

If your vehicle is traveling at the speed of light, the light from the headlights would project at twice the speed of light. However this speed would rapidly diminish to the speed of light. You probably would see the lights turn on, how far the light projects depends upon the light's deceleration.

Answer 5

Unfortunately the answer to this question (at least as far as we know) is totally counterintuitive. One of the basic laws of relativity is that the speed of light is constant in all reference frames. This means that if you turn on your headlights, you will see them, but someone else watching while standing still will not.
Read Einstein's "Relativity" - it's not easy to understand, but it's a good explanation of these things.

Answer 6

how can u be goin at the speed of light when the speed of light is almost unattainable?

if u are near the speed of light, the light will still be projected outwards.

Answer 7

I think that you would see the light in the bulb but it wouldn't be projected forward.
maybe there could be somekind of mechanical failure as all the light energy would be concentrated on the headlights with an accumulative overwarming effect.

Answer 8

The light would be going at double the speed of light. if it came from you vehicle.

Answer 9

you should not see any light in front of you since not light
could reached you at your speed

Answer 10

i never been in space or traveled that fast but im sure they could y wouldnt they? and what would u need light 4???
