it's a well known fact that, at lightspeed you would have trouble thinking fast enoph oke:
if you fitted the new diarrhea Kwick Reaction Automated Pilot system you'll be fine
As anyone whose had diarrhea will tell you....
"you can k.r.a.p. before you have time to think let alone turn the light on" :rotfl:
SSB's old jokes recycling
you've already stated that the bike is going at light speed therefore the mass of the photons hitting the bike would be irrelevant because it's already been taken into account.interesting.
now i propose to you the fact that photons have actually been found to have a very small mass. So, in fact having turned on your headlight, with the emission of photons from that light source, you are actually slowing down and would in fact would see the road in front of you.
This is of course implying that you are not constantly increasing your speed to reach light speed and that maintain a constant forward thrust. Then, the thrust (in the opposite direction) obtained by the emission of photons will cancel some of the forward thrust. This again is assuming that your not running blinkers and brake lights and all that stuff.
I find it interesting to toss this around every now and then. There have been some theories that suggest that light speed will never actually be physically attainable, even if theory says it is... but the sci-fi person in me hopes otherwise.
