when you are jobless yet full of ideas -- this is what happens!!
"If u r driving at the speed of light, what will happen if u turn-on the head lights?"
Prashant:
you wont be able to see the light of head light!!
since relative to you the light particles will be at the source always...it will never come out of it - as simple as this...(eg: you travel at the same speed as your friends car....for u he is always still right)
Rajiv:
even if u r moving at the speed of light...light will have the same speed 'C' in ur frame.(universal constant)
ideally u wont remain on the bike if ur moving at 'C' as u will be converted to Energy
*assumptions hold - we are all safe...mass remains mass*
M = M0/root(1-v^2/c^2) ...
there is no relative speed for light...
its a universal constant for all frames...
(Einstein General Theory of Relativity)
the light from the headlight will still be the same for u on the bike - thats the key.
u will still see everything, assuming no optical dillusions happens at that speed and the road still remains road in front of u
Swapnil:
well its very difficult to say but at that speed effective mass will be zero.
So it becomes an electormagnetic wave. If u some how switch on the headlight,
relative velocity between 2 em waves is always c so u will see light!!
what do u say?
Panigrahy:
hmm... my fundas of relativity are not exactly crystal clear...whats ur answer?
well first thing - when u switch on the headlight the circuit which wil cause the light to glow will itself be electrical, so u'll be travelling as fast as the electiricty in there. Hence there really is no point.
Rejisu:
I think when u r travelling at the speed of light, we cannot see any object from the illumination of this headlight, as the speed to light from the headlight and the your speed will be the same and hence no relative speed between the two.
The point is that still you will be able to see the objects which are self illuminating (like the stars ) and the objects illuminated by the other sources (like the planets )
Isn't it inerteresting!!!!!!!
-- another interesting answer "I dont think the Human eye can see something if he/she travels with the speed of light. so, i believe it doesnt make any diference whether the head lights are on or off."

the verdict - not yet out :D
If you travel at the speed of light light will bend 90 degrees. If you travel at twice the speed then it will bend another 90 degrees. If you travel at thrice the speed then it will bend 90 degree more. Now it will be passing right up the ass of the one who posted this question.
The Verdict should be out only if everyone is convinced with the answers
Hey... now i know what it feels to be on candid camera. :)
I wonder though if my answer would change even if i knew it were being recorded for posterity!
Back to Oracle forms v6.0....

from experience?
true true!
we all should be invited to a physics forum or sthing. I'm sure we can set the stage on fire(literally!!)
my recomendation is get Sriram into the debate, btw..
as per...Einstein's theory of special relativity results from two statements -- the two basic postulates of special relativity:
1)The speed of light is the same for all observers, no matter what their relative speeds.
2)The laws of physics are the same in any inertial (that is, non-accelerated) frame of reference. This means that the laws of physics observed by a hypothetical observer traveling with a relativistic particle must be the same as those observed by an observer who is stationary in the laboratory.
So then..
The light from your headlights will always go at the speed of light in your reference frame. It will strike any object in its path and be reflected back. Everything else will be coming towards you at nearly the speed of light, so the light reflected from it will be Doppler shifted to very high frequencies--towards the ultraviolet or beyond
hope that settles it..
Another 'pointless debate' question- "If there exists a chunk of space frozen in time, can u enter it?why?whynot?"
