It ain't coming back...
*cough
HE ain't coming back, sweetheart...
Considered the club life? -
Probably a silly question, but Planet Earth has more mass than the moon, so why does it not pull it into itself or does the Earths circular velocity throw it out? I can't think of another way to describe it.
-
wow
-
Reading these comments makes me feel like I'm on the smart side of youtube. I've come along way from leeroy jenkins and the emo kid song.
-
I hope you kiss him goodbye first because it ain't coming back
-
What if escape velocity is greater then speed of light??
-
mass is NOT the amount of "stuff" in something. Mass is the measurement of something's resistance to change in momentum aka inertia. something moving will have more mass than it would sitting still, but there is no more "stuff" in said object when it is moving than when it is sitting still. >:\

THESE VIDEOS ARE FUCKIN AWESOME!!!!
-
Thank God there is CrashCourse
-
GRAVITY, DONT MEAN TOO MUCH TO ME
-
This guy is a doffus.
-
I love this guy
-
thanks!nice video
it has cleared my all doubts -
He actually confused me at 3:04
Does a object that is a "victim" to gravity continue to accelerate because it's been subject to the gravitational field for a longer amount of TIME, or because as the object is pulled towards the earth, it continually moves into more and more intense gravitational fields since it's getting closer to the source? -

Gravity affects light because gravity affects energy. Mass is included in this because E=mc^2 (and as you can guess, mass is vastly more influential than non-mass energy since it's multiplied by c^2).
-
It's still easier listening to this guy than some of the other clowns on youtube... but I cannot take him saying something is WEIRD one more time. EVERYTHING is weird to this dude.
-
I heard that photons, do have mass, which is why their speed is not infinite. I could be wrong, but would it not make sense?
-
hey lolll gravity between two objects equals ( gravity - energy + momentum ) that is why light comes toward us :Dd
-
What's stronger gravity or magnetic attraction
