Gravity is made of gravitons which travel at the speed of light. However no one has found it's chemistry yet which is very unfortunate. So I will not be able to answer your question in the way you want.

Isaac Newton came up with the idea of who invented gravity.
A person who made up time, or cavemen.no one actually came up with the idea of time, because time is caused by gravity. The higher the gravity the faster time goes. For Example: If you had one person on Jupiter and another on Earth, the person on Earth would age slower than the person on Jupiter because Jupiter has a higher gravity than Earth.
From what I've read Newton had no idea what actually made gravity work. His famous quotation about this is something like "I make no hypotheses".
Newton was the first to mention the idea but others made changes to what is called gravity. Einstein is one of these.
Isaac Newton came up with the idea. "Many people saw the apple fall, Newton asked why". Bernard Baruch.
saturn's ring is made out of gravity and small rocks.
Gravity was not "made up" by any individual, but was rather observed and described by numerous scientists throughout history. Sir Isaac Newton is known for his law of universal gravitation, which explains the force of gravity between all objects with mass.
I have no freakin idea!!
i have no idea
Idea has no mass though it required a medium to store and process it.
Gravity dams:It is made up of masonry or solid concreteIt can be constructed to any heightLess maintenanceEarth dams:It is made up of soil and gravelIt can be constructed to moderate heightIt is cheaper
gravity is what holds the gas giants. As the gas giants are made up of gases...gravity must hold them in place or they will run off to space..that rhymes.
