Hi I have a few thought experiments I like to see how other peoples
opinions are on the results,
Experiment 1:
A space ship travelling at close to the speed of light shoots a
constant stream of Laser beam out of it's back end. To a stationary
observer away from the space ship, Does the beam travel at speed of
light or does it travel at the speed of light minus the speed of the
space ship?. What does the people on the space ship see?
Experiment 2:
point A, B and C lay on a straight line with B being the midpoint of A
& C. Assuming B to be a stationary point in space. 2 friends depart
from point B in similar space ships, 1 heading for point A and the
other heading for point C at same speed/accelleration, When they reach
their destination, they will both turn back and head back towards B.
Have they aged the same amount when they finally unite?
Thanks,
Ning
