Question

If you see a person travelling through space at half the velocity of light, clocks with him will run
a) At half the normal speed
b) Slower than half the normal speed
c) Slower but not slowed down to half the speed
d) backwards.

Answer 1

b) Slower than half the normal speed

T = 1.1547005383792515 To

Answer 2

That numerically may be correct but I should point out that that's slower, but not slowed down to half the speed... if T = 2 To, it would be half...
