2. What is SCIENCE?
It is a set of tools and systematic methods for
studying the natural world through observation
and experimentation.

4. UNIVERSE
The physical universe is defined as all of space
and time (collectively referred to as spacetime)
and their contents. Such contents comprise all
of energy in its various forms, including
electromagnetic radiation and matter, and
therefore planets, moons, stars, galaxies, and
the contents of intergalactic space.

6. SPACE
Space is the boundless three-dimensional
extent in which objects and events have
relative position and direction.[1] Physical space
is often conceived in three linear dimensions,
although modern physicists usually consider it,
with time, to be part of a boundless four-
dimensional continuum known as spacetime.
The concept of space is considered to be of
fundamental importance to an understanding of
the physical universe

7. TIME
Time is the indefinite
continued progress of existence and events that occur
in an apparently irreversible succession from the past,
through the present, into the future. It is a component
quantity of various measurements used
to sequence events, to compare the duration of events
or the intervals between them, and to quantify rates of
change of quantities in material reality or in
the conscious experience. Time is often referred to as a
fourth dimension, along with three spatial dimensions.
8. ENERGY
In physics, energy is the quantitative property
that must be transferred to an object in order to
perform work on, or to heat, the object. Energy
is a conserved quantity; the law of conservation
of energy states that energy can be converted in
form, but not created or destroyed.
9. MATTER
Matter has many definitions, but the most
common is that it is any substance which
has mass and occupies space. All physical
objects are composed of matter, in the form
of atoms, which are in turn composed of
protons, neutrons, and electrons.
10. DARK MATTER
Dark matter is a form of matter thought to
account for approximately 85% of the matter in
the universe and about a quarter of its total
mass–energy density or about
2.241×10−27 kg/m3.
11. Catastrophe theory deals with
the nonlinear phenomena in which
a continuous change in control
parameters results in a
discontinuous alteration of a
quantity characterizing the
examined system. ...
The theory describes only such
phenomena whose form is
resistant to perturbations–– that is,
structurally stable.
A scientific theory is a broad
explanation for events that is widely
accepted as true. To become a theory, a
hypothesis must be tested over and over
again, and it must be supported by a
great deal of evidence. People
commonly use the word theory to
describe a guess about how or why
something happens

Matter has many definitions, but the most common is that it is any substance which has mass and occupies space. All physical objects are composed of matter, in the form of atoms, which are in turn composed of protons, neutrons, and electrons.
The idea that matter consisted of building blocks or particles originated with the Greek philosophers Democritus (470-380 BC) and Leucippus (490 BC).
Examples of Matter (and What Isn't Matter)
Matter is built from atoms. The most basic atom, the isotope of hydrogen known as protium, is a single proton. So, although subatomic particles aren't always considered forms of matter by some scientists, you could consider Protium to be the exception. Some people consider electrons and neutrons to also be forms of matter. Otherwise, any substance built of atoms consists of matter. Examples include:
Atoms (hydrogen, helium, californium, uranium)
Molecules (water, ozone, nitrogen gas, sucrose)
Ions (Ca2+, SO42-)
Polymers and Macromolecules (cellulose, chitin, proteins, DNA)
Mixtures (oil and water, salt and sand, air)
Complex Forms (a chair, a planet, a ball)
While protons, neutrons, and electrons are the building blocks of atoms, these particles are themselves based on fermions. Quarks and leptons typically aren't considered forms of matter, although they do fit certain definitions of the term. At most levels, it's simplest to state simply that matter consists of atoms.
Antimatter is still matter, although the particles annihilate ordinary matter when they contact each other. Antimatter exists naturally on Earth, although in extremely small quantities.
Then, there are things that either have no mass or at least have no rest mass. Things that are not matter include:
Light
Sound
Heat
Thoughts
Dreams
Emotions
Photons have no mass, so they are an example of something in physics that is not comprised of matter. They are also not considered "objects" in the traditional sense, as they cannot exist in a stationary state.
