The document discusses how time is affected by motion and gravity according to Einstein's theory of relativity. It notes that time moves slower the faster you travel and is also affected by gravitational pull, running slower closer to massive objects like the Earth. As an example, a clock at the top of the Empire State Building would run slower than one on the ground due to Earth's gravitational pull becoming weaker higher up.

1. What do they have in common?

2. Time

3.  1. Nothing travels faster than light.
2. Light is always measured at the same
speed (roughly 186,000 mph.
3. The faster you travel, the slower time
moves, the heavier you get and longer
things become shorter.
 However,
 General relativity incorporates gravity into
the equation and shows how gravity effects
time, bends light and thus effects time.
 For instance,
 A clock on the ground next to the Empire
State building will run faster than a clock on
the top of the building
 Because
 the pull of the earth causes clocks to run
slightly slower then a clock that is further
away from the center of the planet.
