Gravity has mass

[brian334]

Gravity makes things move,
only things that have mass
can make things move.
Therefore gravity must have mass.

Protons, electrons, neutrons, what are they? Is any human capable
of understanding the universe at the atomic level?

gravity IS mass?

or rather the interaction between 2 masses.

all things that have mass, have gravity.
2 gravities = movement.

they have a tendendcy to become one mass. and thus more combined gravity.

imagine something 150 times smaller than a proton. (lets call them pieces)
there are two kinds of these, us mere humans call them + and -
and we only acknowledge their existence in great quantities so that their awesome power can interfere with our medioker gigantic equipment.

These pieces by themselves are immeasurable to us, because of their tiny size.
What we call a 'quark' or 'antiquark' is a large group of these pieces, 50 or so usually... (and we can detece these with out equipment! Yay!) and they are often dominated by one type or the other, and the differing types attract to one another. sometimes they are so closely matched inside with + and -, that they seem to us to be neither, and we call these 'gluons'.

3 of these larger pieces form together into the simplest of the atomic structures.

which can be + or - or a combination thereof.

each larger group or cluster results in more combined mass/gravity
for instance, an proton has more mass/gravity than a quark.
and a group of protons/neutrons has more mass/gravity than a single proton.

To answer your question, any human is 'cabable' of such understanding of our universe. The question remains of wether or not they are willing to seek the knowledge and do something with it.

Oky2,
The issue is mass and gravity.
The question is does gravity have
mass?
