Gravity, Weight, and Vacuum in space:   

As Einstein's theory states, Mass and Energy are Equal and interchangeable, therefore one cannot exist without the other, and energy always runs into mass and visa versa.  This can be observed in our everyday life, as energy from the sun is used by plants to produce mass, and animals can consume the plant mass as energy to survive and increase their own mass, and the mass of animals can be consumed by other animals then returned back to the earth as nourishment for the plants which are using the suns energy to create mass.   Rocks also absorb the suns energy and store it as heat which can be transferred to other units of mass.
Energy is constantly converted into Mass, and Mass is constantly converted into Energy, this conversion of mass and energy has a pulsation effect on the stellar and quantum level .

The density, weight, and gravity of an object is determined by its average atomic mass per volume unit, the greater its atomic mass per volume unit, the greater its energy, the greater its energy the greater its ability to displace space, and therefore the greater its gravity. 

Every mass has a zero point of energy.  The zero point of energy in a mass is its "black hole", the smaller the mass the smaller the center point of energy, the larger the mass the larger the center point of energy.  even an atom has a center point of energy which holds it together and gives it the ability to attract other atoms.  A zero point of energy gets its energy from the kinetic energy of the mass orbiting it.   In a larger system such as a solar system or even a galaxy the same kinetic forces are at work, the more mass pulling on the center point, the more energy the center point has.  Mass is always in a push pull battle between its center point of energy and its kinetic energy.  like an atom, a galaxy is a single mass in space, and as a galaxy ages it mass is condensed and as its mass is condensed the orbit of its mass must increase in velocity to maintain its kinetic energy, therefore the average atomic weight, and density per volume of space also increases.  As its kinetic energy per volume of space increases so does its gravitational pull on the zero point of energy at its center.  A mass like a galaxy has a constant mass to energy ratio, regardless of the volume of space it occupies. 
    As a galaxy condenses the force on the zero point of energy increases transforming it into a larger more powerful "vacuum" or "Black Hole". 
    Since the mass and energy of the galaxy remain constant, when it is forced into a smaller space and its kinetic energy per volume of space increases, eventually the kinetic energy will reach the maximum load of its zero point of energy, or its "black hole" and "Bang!", all of its matter and energy will break free and be expelled back into a larger less hostile volume of space... and the process will start over. 
    Before the big Bang happens the vacuum of the black hole becomes so great that all energy without mass, such as photons, are pulled into its inner orbit at a phenomenal rate.  And since we cannot see the energy of light when it is being pulled away from us we coined the term "Black Hole".  A black hole is the ultimate example of the gravity (caused by kinetic energy) at the center of every mass in the universe.
    In conclusion every atom and every mass has a "Black Hole" in its center.  The atomic weight around the black hole determines its energy or gravity.  The more weight per volume of space around a zero point of energy, the more kinetic energy and therefore the more vacuum and gravity.
    Lose items on the surface of earth like water, rocks, animals, humans, birds, air, etc. don't have an independent center of gravity because we are not independent of earth, we are creatures of earth and a part of the mass of earth orbiting its center point of energy which is constantly trying to pull us in, and our weight has kinetic energy which is holding us on the surface.  Earth is like a large reverse centrifuge and we are part of the lighter mass that floats to the surface.

   The matter and energy of a galaxy will always be equal, no matter the size of the space it occupies.
All galaxies are independent of each other, each galaxy is an infinitely pulsating mass of energy and matter. 

To determine an objects total displacement of space which is equal to its weight, we can multiply its average atomic mass per volume unit by its total number of volume units.  And we can use this figure and its velocity to determine its kinetic energy, which when in an orbit can give us its zero point energy and gravity... I will need help with this?

Objects can have a set volume with low average atomic mass per unit, such as wood.  Or a high average atomic mass per set volume unit such as gold. 
This explains why Gold weighs much more than wood.

***AVERAGE ATOMIC MASS: A figure used by chemists to specify the mass—in atomic mass units—of the average atom in a large sample.  The average atomic mass of carbon, for instance, is 12.01 amu. If a substance is a compound, the average atomic mass of all atoms in a molecule of that substance must be added together to yield the average molecular mass of that substance.

The weight of one object on Earth is its weight plus the weight of Earth minus the weight of Earth, which means each mass has it's own independent weight in space.  On Earth we set a scale to zero which sets earth's weight to a constant force represented by zero, our body has a weight of its own, which means we have an independent weight in space of our own, lets call it a "cosmic weight" or maybe total atomic weight. 
Therefore:  When we step on a scale which is set to zero, our body weight is the sum of the combined attraction between our weight and earths weight less the weight of earth which was set to zero. Technically we are part of earth's total weight. 

All matter making up earth has gravity,  therefore all matter making up earth is attracted to each other.  As the matter of earth was pulling together it created a larger and larger mass with a larger volume and therefore  a greater total weight, or gravity per volume unit, and the closer to the center the greater the density...  If you drop something directly to earth which is moving at the same velocity as earth, (no forward kinetic energy) the object does not fall to the surface of earth, it falls towards the earth's center point of energy!  Earths surface only gets in the way.

Since every object in space has a volume made up of atoms, and atoms contain zero points of energy and electromagnetic energy, the combination of these two creates gravity... It stands to reason that a smaller mass of great atomic density can overpower a much larger mass with a low atomic density.

This also explains why the nuclear bomb is so devastating, when something breaks down a nucleus and instantly releases the phenomenal energy of this phenomenally dense bits of matter, it instantly releases the phenomenal energy which is stored in the nucleus.  Since mater is equal to energy, the denser the matter the more the energy. 

Matter in space is everything... from a single photon to the largest galaxy.

Space is infinite therefore Space can have no center, only matter can have a center, and that center is phenomenally dense, as stated above. However outer space has an atomic weight of approximately one atom per cubic meter of space... I guess I could say that space has a density of at least one atom or "zero point of energy" per cubic meter.

Relative to space a nuclear bomb is just a little puff.

Einstein says gravity warps space;

I say gravity is caused when matter occupies space. 

The course and velocity of light's energy can be altered by stars, since stars have a large overall weight, which equals a large overall zero point of energy or gravitational energy.

Weight and Gravity in space:

Weight = average atomic mass per volume unit x total volume units.
Gravity = Average atomic mass x velocity x orbit ... ?
Density = average atomic mass per volume unit.
