What evidence do we have that the velocity of light
is a universal constant? What is the significance
of that observation?
Why do we say that the speed of light is the speed
limit of the universe?
If you could make a detailed observation of the
Enterprise as it passed the Earth at 90% of the
speed of light, what conclusions would you draw
about the measurement of lengths and times on
If you were on the Enterprise moving at 90% of the
speed of light past the Earth, what observations
would you make about the measurement of length
and time on the ship?
What kinds of evidence exists for length contraction
and time dilation in real experiments?
If you were in a spaceship traveling past the Earth at
0.9 c and another spaceship was traveling toward you,
also at 0.9 c, with what speed would you see the other
