Gravity has mass

How do you know small objects have gravity?
Has it ever been measured or is it just a theory?

Are you talking about gravity or gravitation? Because their not the same.  First, lets start with Galileo. He showed that gravitation accelerates all objects at the same rate.  Second, the terms gravitation and gravity are mostly interchangeable in everyday use, but a distinction is made in scientific usage. "Gravitation" is a general term describing the phenomenon by which bodies with mass are attracted to one another, while "gravity" refers specifically to the net force exerted by a mass on objects in its vicinity as well as by other factors, such as the masses rotation.
All matter has its own gravitational field and is attracted to other matter.  You yourself have gravitation. The size of mass/density/rotation defines the gravitation strength or pull on other masses. Take the moon for an example it is very small in the big universe yet it has a gravity and gravitation and rotates. So if small things did not have gravitation or there is no gravity then you could throw it up in the air and it would keep going right out into space. Matter is matter and can't be anything but matter with laws that matter must conform to.

Weight is the amount of pressure or force an object that has mass is exerting upon another object that has mass.  You can't have weight if there is no gravity or pressure being exerted between the objects.

Mass is the amount of pressure or force being exerted between itself and space-time.  This pressure or force also causes space-time to bend.  You can't have mass if space-time is not exerting a force or pressure against it. 

Take the same object where space-time is not putting pressure against the object, then the object will have no mass.  If the object has no mass, then space-time is not curved due to no pressure between the object and space-time, thus no gravity.

The denser an object is, the more it causes space-time to curve.  The more space-time is curved, the more pressure it puts upon the object, thus more mass.

The photon does have mass, contrary to what most believe.  When it is traveling at C, then it's relative mass is huge.  It's relative mass is huge because it is exerting a great amount of pressure against space-time due to it's speed.  The higher it's speed, the greater the amount of pressure space-time is exerting on it, thus giving the photon more relative mass and causes a curvature in space-time due to the pressures between them.  The photon will follow this curved space-time, which is a corkscrew or helical motion.

Gravity is mass.  Gravity or Mass is the pressure being exerted between an object and space-time.  Space-time is exerting a pressure against the object which gives the object mass, and the object is exerting pressure against space-time which causes it to curve.  This interaction between an object and space-time, gives the object it's mass and causes space-time to be curved.  Without this interaction, there is no mass, there is no curved space-time, there is no gravity.

In the standard model, the Higgs Boson gives mass to every elementary particle which has mass, including the Higgs boson itself.  In quantum field theory, the graviton is a hypothetical elementary particle that mediates the force of gravity which causes space-time to be curved. 

Neither is correct.  Every elementary particle that has mass is due to space-time exerting pressure on it and is not caused by a hypothetical Higgs Boson that has mass which sticks to the massless elementary particles to give it mass (LOL).  The reason for this hypothetical Boson, is because all of the elementary particles that were predicted in the standard model to be massless, was discovered to have mass.  This forced them to come up with a theory about mass, and the Higgs Boson was their answer,  LOL. 

Space-time is curved due to the mass exerting pressure on space-time and not caused by a hypothetical graviton that is massless (mass causes space-time to curve, not something that is massless...LOL).  This is almost comical.  Physicists are chasing the wind.  If they defined mass properly, then they would know this.

The important question to ask is can gravity transfer mass?
For example can gravity transfer mass from the earth to the sun?

Sure, if the mass escapes the influence of the earth's gravitational field, assumes an orbit that is non-degenerative, isn't captured by the gravitational field of another body and is eventually captured by the sun's gravitational field, then that mass will be transferred from the earth to the sun. It may later return to us as a constituent of the solar-wind if our magnetosphere doesn't cause it to veer-off, or perhaps as photons or other particles.

The -effects- of gravity are well known, the -causes- are conjectural, which is why I don't use phrases such as: 'gravity is a depression in space-time' but rather: 'it is conjectured that gravity is a depression in space-time' (which is the accepted explanation, for the time being).

Why do you ask these retarded questions all the time?  The answers to all this light/mass/gravity stuff are easily obtainable with a Google search.  You are trying to make gravity to be something it is not.  You should familiarize yourself with what a force is, and then maybe the correct answers will come to you.

more like atoms create gravity.
and gravity is what we recognize as mass
because gravity causes weight, and likely kinetic force.



gravity is just magnetism,
which is moving from a positive charge,
towards a negative charge.

AKA gravity/magnetism moving from the positive ionosphere,
towards the negative sand/stone of the ground.



if you reversed the charge,
so that the ground was positive and the sky were negative,
than gravity would flow UP instead of DOWN !


the catch is that for complete reversal,
the positive polarity, would have to be stronger,
than the grounds negativity.

and the negative polarity, would have to be stronger,
than the sky's positivity.



if the ground and sky have a stronger charge,
than you would merely have reduced weight.

and reduced weight, is an easy thing to not notice !
