I have a question that I and a friend have been arguing about. I
was wondering if someone could help me out? The question is this:
If 2 people are 2 light years apart. Person 1 wants to signal Person 2.
Person 1 has a laser and a rigid stick that is just a few inches short of
2 light years in length (almost touching Person 2). At the exact same
time, the laser is shown at Person 2 and the rigid pole is pushed into
Person 2. Which will reach Person 2 first?
Assume the pole is rigid and there is no sideway flexing.
If someone could please help us out, it would be very greatly appreciated.
