A tiny sliver of wire and a heavy lead sphere are floating in space, in the cold quiet vacuum, wedged between stars and galaxies. They are space debris from one of the Apollo missions, leftovers from a giant leap to mankind, astro-junk.
Some space debris falls back to earth and finds its way onto eBay. You put the embroidered handkerchief I gave you on eBay. I bid for it but billoguo42 outbid me.
Newton said gravity is the attractive force something large exerts on something small.
Actually, all he said was f=ma.
I've simplified it for you.
or maybe I've made it more complicated.
I don't know.
The sphere attracts the wire and it dances around it like a model of the moon. A perfect orbit that'll go on till infinity.
We are like the sphere and the wire but gravity doesn't work.
We don't orbit each other.
We only orbit the sun.
