Brian Greene: "By 1915, with his "General Theory of Relativity,"
Einstein took these realizations one step further, concluding that
something similar happens in a gravitational field. He figured out
that the stronger the gravity you experience, the slower time elapses.
After synchronizing our watches, were I to stay in the lobby of the
Empire State Building while you went sightseeing on the observation
deck, I would experience stronger gravity (being closer to Earth) and
according to Einstein, when we rejoin, my watch would be behind yours.
The effect would be incredibly small, since the difference in gravity
you and I would experience is trifling."

Silly Brian does not even understand that the idiocy called
"gravitational time dilation", as defined by his cleverer brothers,
depends on the GRAVITATIONAL POTENTIAL difference between "you and
me", not on "the difference in gravity you and I would experience".
