If I'm in a vehicle moving at the speed of light and I turn on the headlights...would they do anything?

Answer 1

Albert Einstein answered this question a long time ago. He theorized (and every experiment since then has borne him out) that the speed of light is constant from ANY inertial (non-accelerating) frame of reference. This includes the speed of light relative to your headlights.

Light speed is constant. What changes is time and length. Weird but true.

Answer 2

If we discount the fact that you, or any object, will never achieve the speed of light, this question becomes a lot more complex than you might believe.
This is due to the fact that, at the speed of light, your time reference slows to zero - time actually stops in your reference.
All functions slow with the dilation of time - both at the atomic level as well as the biological level. It seems to me that it would require a certain amount of time to "turn on the headlights" - and you wouldn't have any time.
However, up to the speed of light, your headlights would perform normally. This is true at any uniform velocity up to the speed of light.

Answer 3

Your headlights will go at twice the speed of light, so 2 X 299,792 km/second. Think about this. If you can throw a ball at 20 km/h,and you stand on a car going at 20 km/h and throw it, the ball isn't going to stay in your hands; it will go at 40 km/h.

Technically travelling at light-speed is possible; in space there is nothing to slow you down, so choose a path that is free and keep accelerating. Various acceleration methods; gravity jumps, traditional fuel, solar sails, etc. As long as you don't crash into something you will keep going, and can only accelerate. Which is why I think there should be no limit to speed, not even light.

Answer 4

Einstein asked this very question, greater or much less. that's why not something can commute on the fee of sunshine. What occurs is that the headlights shine forward on the fee of sunshine. If the motor vehicle is traveling close to mild velocity, the subsequent question is relative to what? so some distance as you sitting in that motor vehicle is going, you're status nonetheless and the headlights are doing their interest, illuminating what's in front of you. the fee of sunshine is consistent, in spite of the reference physique. If somebody observed you zipping by making use of at just about the fee of sunshine and observed you change on your headlights, the observer might see the sunshine out of your headlights moving on the fee of sunshine, as might you, in spite of your state of action.

Answer 5

Your lights would turn on as normal. In fact, the light from your headlights would appear to travel at the speed of light to an observer. Einstiens special relativity sais nothing goes faster than light. The speed of light does not add in this situation. When you look at light, you always see it going at c.

Answer 6

First off homeboy you can't have a vehicle that fast. Second who cares you must be taking physics and this is a test question don't ask me to do your work for you. The answer is you wouldn't be able to tell because you wouldn't be able to see the car's instrument panel to even turn on the headlights we see from light reflecting off of objects if you are moving faster than light you can't see because light would not have time to reach your eyes before you passed it by.

Answer 7

First off, you CAN'T travel the speed of light. Second of all, why would it matter if you need the lights because IF you EVER could travel that fast, you'll be going so fast you couldn't see anything!! So why does it matter once you won't achieve that?! (At least with a regular vehicle anyway...)

Answer 8

If u are traveling at the speed of light u are dead.

Answer 9

does it matter you are never going to move at the speed of light anyways

Answer 10

yes they will. Your lights will be going twice the speed of light, so they will be going double the speed.
