Gravity, Static and Polarity

Okay, Round-Earth gravity pulls. I know it's there, to some extent, and it's contant, sure. But -why- is it what it is? What makes it constant, what makes it pull down at the same rate? What does that have to do with a round earth?

I've got a better quote. It's shorter: "Gravity doesn't exist, Earth Sucks."

Experiment shows that everything with mass attracts everything else with
mass in the universe. This strength of this attractive force depends on
the mass of the objects concerned.

In most cases this force is far too weak to be felt. eg. the force of attraction between you and the building you walk past from time to time.

It would take an object as massive as a planet to make the effects of this
force felt.

think about centres of mass.

if we had a FE, gravity would pull to the centre of mass which would be the north pole for a FE disc. if this was so, only at the north pole would you be pulled downwards by gravity. people in australia would experience nearly horizontal gravitational pull!

this is blatantly bollox since wherever you are, the gravitational pull is vertical therefore wherever you are the earyth's centre of mass is directly below you therefore the earth can only be a sphere.

Gravity does not exist with the Flat Earth.

By felt, I meant felt by any ordinary person.

Do you have any idea how sensitive that equipment was for the cavendish experiment??????????????? :?:  :!:

The forces he measured must have been in the range of 1/1000 of
a Newton.

I'm interested to know how he used a telescope to measure the twist in the wire.  

Maybe mounted the telescope at the center of the rod and aimed it at some kind of distance index far away?
