what will happen if travel at light speed & then i on my headlights ?

Answer 1

This is all theoretical, because you cannot travel at light speed.
But let's assume you could get vanishingly close to lightspeed.

You know that time slows down as you get faster, and that distance shrinks from an external observer's point of view? Well, at lightspeed, time stops, and the dimension shrinks to zero. So if you are very close to lightspeed and reach for that button, you will be so slow that light coming out will look like it is still traveling at lightspeed.

This is what Einstein meant by everything being relative. No matter what you do or where you are, you will always see light speed in a vacuum as a constant, it is everything else (space and distance) that changes to make that light speed a constant.

Answer 2

Nothing happens. If you are on earth you would have burned up long before you got to the speed of light from the friction created by the atmosphere. If you are in outer space you have already reached the maximum speed for light so your headlights can go no faster.

Answer 3

Quantum of light is a particle and wave simultaneously.
Exact there is a simultaneity of space and time.
For me such explanation is unsatisfactory.
It just as to speak, that the logic information and
the senseless message are the same simultaneously.
To say half truth is worse then to say lie.
* * *
Quantum of light is a privileged particle.
Only the speed of a light quantum has
a maximal, constant, absolute quantity of c=1.
No other particle can travel with the speed c = 1.
If quantum of light flies always rectilinearly c=1, it is a mad one.
Is he really mad?
* * *
Only a light quantum has the absolute speed c=1.
No other particle can travel with the speed c = 1.
Other particle can travel only with the speed v=s/t.
And I was taught at school from the first class:
that the incommensurable quantities cannot be compared.
To connect incommensurable quantities it
is similar to the decision of a problem:
“What will be if the whale will attacks the elephant?”

Answer 4

Nice one, that!
Yeah, if at all it's possible to travel at that speed...
Well, it must be as good/bad as travelling without headlights! Because we use headlights so that they illuminate the way ahead for us. And illumination in this context is reflection of light from physical objects in the path ahead so that you "know" where/what you are heading towards... Hmm... now, you yourself are travelling at the speed of light, so, by the time light from your headlights reaches any object in your path, the headlights themselves reach it, so, before you see something, you have already passed/bumped into it.

Answer 5

1. You can't travel at light speed.
2. The speed if light is constant, regardless of where you are or how fast you're moving. If you turn your headlights on traveling at half light speed, the light will appear to move at the speed of light to you, and the guy you're passing by.

I know, it messes with your head.

Answer 6

You will then travel at the same speed of your headlights. And theoretically you will not be affected by the passing of time/time will move much faster than you. (ex. You travel at lightspeed for a week. A year will have passed on Earth)

Answer 7

According to the theory of relativity .. ur headlights will turn on anyway .. assuming that u can travel at the speed of light... the light emitting from it will travel along with u ... its like trying to add infinity and infinity..... u get infinity ....

Answer 8

if u travel with the speed of light or more than that then u will be in future.
there is a simple logic in this, that sun light comes to earth in around 8 min. but actually the sun has emitted the same packet of light & energy 8 min. ago . by this u can conclude that if u travel with the speed of light u will get to see the future.
one more thing the concept of "time machine" is also based on this. simply time machine is a device which can run with or greater than the speed of light but it is never been made till now.....but i should tell u that research on this field is going on & hopefully we will get to see one in our future.

Answer 9

It is obvious thant u can nothing.The light from ur vehicles head light should get reflected from the object before reaching ur eyes. By that time u might havemoved forward. moreover ur mind cannot process the images at that speed.

Answer 10

i don't believe you can, with einsteinian physics, at least, actually even REACH the speed of light (with a car, at any rate). it was just this sort of thinking that led einstein to his theories of relativity, though, so you might look for an answer in a summary of those.
