in 1915 Einstein published his
groundbreaking theory of general
relativity according to its theory space
and time are intertwined together they
form a four-dimensional fabric space and
massive objects can warp that fabric now
everything in the universe including
light travels through space-time so if
the gravity from a massive object was
based on the past that light travels and
conceives men this blew people's minds
up until then the concept of gravity
came from iron in his worldview space
and time were absolute and independence
so i've x idea was really radical Oh the
problem was there was no way to test his
idea in the lab though his equations
predicted that only a truly massive -
warp space-time enough to make the light
bending effect visible something as
massive
for example as the Sun up dude luckily
just four years after Einstein published
his favorite theories a total eclipse
allowed an astronomer named Sir Arthur
Eddington to test it the eclipse was
going to occur
just as the Sun was crossing a distant
star cluster scientists knew where these
stars normally appeared in the sky at
night if Einstein idea was right then
when the massive Sun crossed in front of
those stars he would warp space-time and
shift the apparent position of the Stars
farther from the Sun but usually the
brightness of the Sun would make the
stars impossible to see during that
solar eclipse when the moon blocked out
the first light the stars were visible
and Eddington measured the effect
whoa his experiment demonstrated a light
curve as general relativity predicted
meaning light shines down the path
started because I thank you for figuring
out how the universe work that we was
equipped over America on August 21st
