Learn about Gravity
Learn more about general relativity, Isaac Newton and Albert Einstein
with this fascinating gravity video. As the story goes, back in 1665
Isaac Newton observed an apple fall from a tree and from there began to
understand gravity and how it worked to keep the moon in earth’s orbit
as well as keep humans and various other objects attached to the
ground. Newton’s theories of gravity were revolutionary at the time but
weren’t perfect, it took nearly 250 years before these issues were
addressed. Along came Albert Einstein, who realized that there was in
essence a universal speed limit, the speed of light. That nothing could
go faster than this contradicted Newton’s theories and so evolved
Einstein’s theory of general relativity. Check out this amazing gravity
video clip and see for yourself how it all works.
