What is gravity?
I've been reading up on gravity, wondering exactly what it is. I thought it was a simple question but seems it's not.
From what I understand, Newton imagined gravity as a force of attraction of some kind, but he didn't know what exactly.
Einstein "corrected" Newton's physics with relativity and said that gravity is a result of the geometry of the universe and not a force.
But relativity doesn't work on the quantum level and so they believe there must be a quantum explanation for gravity which leads it back to being a force. Hence the graviton.
Am I getting any of this right? Does anyone know exactly what gravity is?
