If you shine a flashlight forward while travelling on the bow of a ship going at the speed of light, will the light go anywhere?
Trick question - A ship cannot attain the speed of light.Drunken Master said:If you shine a flashlight forward while travelling on the bow of a ship going at the speed of light, will the light go anywhere?
What if it could? Hypothetically speaking.danmand said:Trick question - A ship cannot attain the speed of light.
The light would still shine forward at the speed of light. The speed of light through empty space is constant.n_v said:What if it could? Hypothetically speaking.
Between Lorenz-Fitzgerald contractions and uterine/vaginal contractions, i prefer the latter!xarir said:The light would still shine forward at the speed of light. The speed of light through empty space is constant.
One would have to take into account though the effects of time dilation and length contraction within the 2 different frames of reference (on the ship and off the ship).
Do a Google on Relativity Time Dilation for more info.
You are correct on the first question, but you are wrong on the second one. Light cannot travel at twice the speed of light(!), no matter from where you observe it.tboy said:Cuz they are smart enuff to realize the question really is a waste of friggin time as no one in our life time will ever travel at the speed of light! LOL
BTW logically speaking: the beam of light you are holding in your hand will still travel at the speed of light away from the boat. If someone were on a stationary object then, in relation to them, it would be travelling at twice the speed of light.....
