Has it ever been proved that gravity is proportional to mass?

I think a very interesting question to raise here, is how to measure Mass ! Weight scales assume that weight and mass are related, i.e. gravity is proportional to mass. Therefore our basis for measuring mass is with the assumption that newtons law of gravity is correct.

Isnt there any other more fundamental way to measure mass, as an independant unit ?

they got the mass of atoms, electrons and other stuff right so why not calculate the mass from those?

Yes. Any idea how the mass of these were calculated ?

electron's mass was taken by milican's oil drop experiment try googling

I think that you(Mojo) has explained this well. I also kept to think ages about thinking how the gravitional force generated. Because it is not follow the the first rule of thermo static science.(Thapa gathika, i dnt knw da correct english word). Next problem is how objects can wrap space and time arround them ?
Acctually i dnt have enough mathematical knowledge to understand da quantum science theories.

The Bigger / heavier objects must have far more gravitational force thn smaller objects...

How otherwise can you explain a black hole ??

WHo can explain that ?

Here bro i have a quation. Just think that huge masses can wrap space and time around them. Then consider about a 1m^3 object. This object should be large(at least in appearing) in space than it is in earth. because space near the earth is compressed as shown in figure. Is this acctually happening or is this an wrong thought ??
