Time
Supanat Potiwarakorn [Boss]
Time appears to have a direction
Time is Absolute
illusion of consciousness?
Speed of light
~ 300,000 m/s
For any observer,
speed of light stays the same.
Michelson–Morley experiment (1887)
t = \frac{s}{v}
t_{train} = \frac{2}{c}
t_{ground} = \frac{1000002}{c}
time passes slower in the train
Time Dilation
It takes infinite energy to move faster than light
Time is Absolute?
Special Relativity Theory
non-accelerating frames of reference
no gravity
But gravity can cause time dilation too
space-time
time passes slower in higher gravity fields
age faster
