The best theory is that all matter was created at the Big Bang
A piece of chalk is matter because it has mass and occupies space, which is the definition of matter.
The Big Bang supports interpreted observational evidence of the Cosmic Microwave Background Radiation (CMBR) barrier that the universe is Time bound (or has a finite existence), that the universe is expanding (within the dimensional limits of Space and Time), that the universe is evolving a set amount of matter and energy while it is expanding over time, and that the universe is homogeneous and isotropic with respect to Space and Time.
Because any matter that pulls you to one side will be compensated by another piece of matter that pulls you in the opposite direction.Because any matter that pulls you to one side will be compensated by another piece of matter that pulls you in the opposite direction.Because any matter that pulls you to one side will be compensated by another piece of matter that pulls you in the opposite direction.Because any matter that pulls you to one side will be compensated by another piece of matter that pulls you in the opposite direction.
Its a piece of matter
It has mass and volume, the characteristics of matter.
gravity attracts the moon to the earth, us to the earth, the sun to the earth, the earth to the sun, and every piece of mater to every other piece of matter.
In the universe, matter is neither created or destroyed. If you burn a piece of wood, it becomes ash, smoke, heat and light energy.
A piece of chalk is matter because it has mass and occupies space, which is the definition of matter.
If you ignore the small contributions due to every other piece of mass in the universe, it's zero.
Every Piece of Me was created in 2003.
If the material is pure and homogeneous, i.e. "the same throughout", then the density is independent of the size of the sample. A chip the size of a pinhead and a chunk the size of a truck have the same density.
It is "piece." The original saying is "Speak your piece" meaning to have your say in the matter. Both spellings are correct, although speaking your "peace" only makes sense in a very limited context - that of "peace", while "piece" makes sense in nearly every other context.

Space can be occupied by matter. If not how do planets move? If you're asking: Does outer space have matter? Then I would say yes, but very little, little enough to be called a vacuum. Outer Space has a few atoms per square meter.
There are a number of instruments that are played in the opening credits of Stargate Universe. It is an orchestral piece.
No one really knows how gravity works but what we've observed is that anything that has mass has gravity. So every single piece of matter that makes up a planet is gravitationally attracted to every other piece and they stick together as a unified whole.
