How mass attracts other mass

[Cyclone]

He didn't say to drop them to be fair, so I assume he was placing them on a flat surface and hoping to disprove gravity by the fact that the marble doesn't roll towards the lead.

This is of course due to insufficient force being applied to overcome it's friction.

Can't you explain it without using the smokescreen of advanced maths?

 

The maths to calculate the scenario that the conspiracy nut suggested is not complex nor a smokescreen, it's simple and demonstrable.

It doesn't explain WHY gravity exists, but maths can't explain why something, it just explains how something.

It's like asking WHY the weak nuclear force exists, or electromagnetism. I doubt there is a WHY, a why implies that it's for a reason which leads you down all sorts of ridiculous reasoning paths about prime movers, which themselves are circular and unresolvable. These forces simply are, they describe the behaviour we can see, to the best of our understanding there isn't and can't be a why.

Most people are less attracted to larger masses.

Roman Catholics are attracted to Masses.

Thanks, Ghozer. So give us a summary. How does quantum field fluid dynamics and the quantum field affect the movement of geodesic lines?

And Cyclone my friend, isn't it just semantics to say WHY cannot exist. You say the reason leads us up wrong paths but for example the reason WHY a mass moves in a gravitational field is that it has a force applied to it. HOW it moves describes the path it takes. The WHY question is therefore perfectly valid in science. COMMENTS?

well think about it logically..

 

as the mass is attracted to each other (or whatever else) the lines will also move/change as the mass moves, you need to look into quantum field fluid dynamics and how the quantum field affects the movement of geodesic lines...

 

they always follow a parabolic arc with the centre point of the curvature being at the centre point of the mass.

 

Yes, but WHY or if you prefer HOW and by what mechanism are the masses attracted to each other. Presumably the geodesics of spacetime in the absence of mass are straight lines. So the geodesics belong as it were to spacetime, not the masses. But when mass comes into the situation it distorts these geodesics. What mechanism makes it do that?
