I always thought, newton proved that two bodies attract eachother, so everything that is drawn to the earth by gravity, pulls the earth to itself aswell, there for creating the opposite force of Gravity
the thing about Anti-matter is true but Newton didn't know anti0matter existed when he made his laws
ah but thats not the case. yeah two point masses will attract using Gm1m2/something or other but that isnt the case with the opposing forces.
The opposing force would be repulsion. im talking gravity being attraction so what is its opposing force.
Have you heard of strong nuclear force. its basically a force in the atom which works over extremely small distances. were talking -10^6.
at some points it attracts but if the atoms get too close it will repel. hence there is an origin and an opposite.
Same with magnets and electromagnets and dipoles. there is always an oppossing force and they are equal and opposite. so what is gravity's if there is one. otherwise it is not a true force.
Ciao for now.

I only had one hour physics a week in high school so I have very lil knowledge about astro or atom physics
but I can give you the email addys of my friends who study at uni
mostly civil engineers tho I have one mate, one of my best friends, who's specialising in space aveonics (sp) and astrophysics so he might be able to help out
