What holds the moon up? Moonbeams! Subscribe: http://bit.ly/iotbs_sub Twitter: @okaytobesmart ↓ More info and sources below ↓ According to Newton's law of gravitation, the sun should "pull" way harder on the moon than the Earth does. So does the moon actually orbit the Earth? Why? Special thanks to Ariel for submitting this awesome question to our Facebook page!

I'd like to challenge you, to make a REAL scale of the sun-moon-earth to make a solar eclipse, and how to calculate / predict it, put all of the variation, the speed of the earth and moon to rotate and revolve, the gravity, etc, can you? It's okay if you smart

The Earth is FLAT
-
the moon has parts of the Earth
-
earth and moon are binary systems they go around each other...

GOD NO THE PORTAL COULD START HERE

Wouldn't the moon's path would look like a spiral if you add a 3rd dimension?
-
but the earth has an eleptical orbit around the sun and
the moon has an eleptical orbit around the earth too
the patern should be more eleptical -
HOLD ON A MINUTE
if the moon had an atmosphere, and was a bit smaller than Sun in relation to earth, would the sky be red during solar eclipses? -
Luna [moon] orbits Earth [planet] orbits Sun [star] orbits Proxima Centauri A [red giant star] orbits Sirius A [black hole/Centre of Milky Way] orbits Unknown [?]...
