This is a short introductory article on physics it in includes links to articles on Thermodynamics, Quantum mechanics, Relativity and other theories of modern physics. It is short because it is a entirely introductory article with most of the material on other pages that it links to.

The Science of Cosmology

Cosmology: The scientific discipline dealing with the origin, structure, and relationships of the universe
A cosmology: Any theory or doctrine that describes the natural order of the universe.

Every civilization has had a cosmology as far back as it known and they have usually taken the form of a philosophically based mythology.  Increased knowledge in Physics and Chemistry has resulted in a more scientific approach but philosophic assumptions still play a major role in Cosmology.

The expansion of the Universe was discovered by Edwin Hubble discovered in 1929 by measuring the redshifts of distant galaxies. In 1998 it was discovered the expansion of the universe to be accelerating based on observations of type Ia supernovae.

Cosmic Background Radiation is the thermal black body spectrum that is nearly uniform in every direction, It represents a temperature of 2.725 K peaking in the microwave range a frequency of 160.2 GHz, with a wavelength of 1.9 mm. It was first observed in 1965 by Arno Penzias and Robert Wilson at the Bell Telephone Laboratories in Murray Hill, New Jersey. The CBR temperature fluctuations discovered by the WMAP data of the entire sky showed an average temperature is 2.725 Kelvin with tiny temperature fluctuations spanning about 0.0002 degrees Celsius.

The Big Bang Cosmology is the current Cosmology of the scientific establishment. The model starts with all mater and space squeezed into an infinitesimal dot called a singularity. This infinitesimal dot suddenly underwent an extremely energetic expansion commonly described as an explosion. Over time the heat of this expansion cooled eventually forming galaxies, stars, planets and eventually us. CBR is seen as residual heat from the Big Bang red shifted by the expansion of t he universe. The Big Bang is based on three main purely philosophical assumptions. First there is absolute naturalism with no intelligents or purpose being allowed in the process. The universe is considered to be unbounded with no edge that is no point beyond which there is no mater. Finally there is the cosmological principle which states that the universe looks the same from every place. The goal is to deal with the fact that we seem to be at the center of the universe by making every place look like the center

There Other Naturalistic Cosmologies such as the steady state cosmology which has no beginning or end to the universe but requires a continual source of new matter. There is a new Cosmology called the electric universe which depicts much of the phenomenon in universe as being electrical in nature. It is not yet fully developed.  

Creationist Cosmology is based on three main purely philosophical assumptions. The first is God as the creative intelligents with purpose in the process. The universe viewed as bounded with an edge beyond which no mater is found. There is a center to the universe and the Earth is near it. Now this is not Geodetic because the universe does not rotate around the Earth Plugging these assumptions along with the observed expansion into relativity results in time dilation at the center where the Earth would have been producing a time line on Earth consistent with the Biblical account. CBR is seen as the light God created on day one red shifted by an expansion factor of about 3,300.

In conclusion Cosmology deals with the origin, structure, and relationships of the universe but is heavily dependent on philosophical assumptions since we only see the universe a one location that is the Earth. Evolutionary and Creationist Cosmologies are based on different assumptions producing different results for the same data.

The Point of Matter in Physics

Matter: Anything that has mass and occupies volume. It is the general term for the substance of which all physical objects are made.
Mass:  In the generally sense it is the amount of matter in an object. It is the term for two properties of matter that are equal in value: inertial mass gravitational mass.
Inertial Mass:  The resistance of a body to acceleration when responding to force.
Gravitational Mass: Property of an object that determines the strength of its gravitational field and its reaction to gravity.           

The existence of a relationship between the inertial and gravitational mass of an object is evident from the fact that they have same the value. However General Relativity shows that inertial and gravitational mass are two aspects of the same thing.

Special Relativity shows that an objects mass is equivalent to the amount of energy an object contains.

The SI unit of mass is the kilogram which is a mass equal to the mass of the international prototype of the kilogram. It is based on the gram which is the mass of 1cm3 of water and that kilogram is the mass of 1000 cm3 of water.

There are 3 main states of matter with distinctions based on differences in bulk properties. They form a triad with each one able change directly to the other two. Other forms are called states exist but they mainly are variations of these three.

Thee Main States of Matter

Solid – A definite volume and definite shape.
Liquid - Definite volume but no definite shape.
Gas    - No definite volume or shape.

Plasma is commonly called the 4th State of Matter. It is an ionized gas where electrons have been freed their atoms; usually by heat. It is mainly an extreme form of gas with all defining characteristics of a gas that is no definite volume or shape. It is the most common form of normal matter.

Normal Matter is composed of atoms. Atoms are a nucleus; made of protons and neutrons; with electrons around it. This form of matter in what we commonly experience. Matter makes up everything around us, everything we see, everything we touch and even our bodies.

Matter is one of the three main parts of the Universe Space, Time and Mass. (matter) Relativity shows them to be inter-related in that space and time are so interrelated that they form a single entity called space-time. Furthermore mass warps space-time forming gravity and the motion of mass contracts both space and time.

In common experience matter is what makes up objects around us and Physics has shown that it to be a lot more. Matter is a fundamental part of the universe.

Space is Not Nothing

Space is the three dimensional extent in which objects and events occur, with a relative position to other objects and events. In a more general sense space can refer to an nth dimensional hyper-volume. 

Space is often illustrated by 3 lines representing the three spacial dimensions. They are the axis of a 3d graph. In 3d space you can move in 3 directions forwards and backwards; up and down and left to right. General Relativity depicts space and time as a fabric that can be warped, bent, twisted, stretched and contracted. Quantum Mechanics describes subatomic particles coming and going even in a vacuum. Space is not empty, it is not nothing. Yes I know this is a double negative however empty space is normally thought of as nothing but it is something.

Basic SI unit – meter (m) which is the distance traveled by light in a vacuum in 1/299,792,458 of a second.

The most common methods of measuring space are rulers but odometers are another common way of measuring distance and there by space. Other methods include bouncing light, radio waves, or sound off of an object using the return time to measure distance. These include radar and sonar. Parallax uses geometry to measure distance it is used in Astronomy and land surveying.

Distance and position must be measured according to some standard. The standard has to be a chosen point in space. The point is selected by ether convenience or convention with out such a starting point determining distance and position is impossible..

Space is one of the three main parts of the Universe space, time and mass. Relativity shows them to be inter-related with space and time are so interrelated that they form a single entity.  Intern mass warps space-time forming gravity and motion of mass contracts both space and time.

In conclusion based on common experience space is basically where you are. You are at a particular point in space relative to other objects. Physics however has shown it to be a lot more. It is a fundamental part of the universe.

It is Time for Physics.

Time is the dimension that is characterized by sequences of events. In physics it is seen as a 4th dimension

The basic SI unit for time is the second. Its duration is defined as a 9,192,631,770 periods of the radiation of the transition between the two hyperfine levels of the ground state of the cesium133 atom. It was originally defined based on a day.

Other units of time include the minute which is 60 seconds, the hour which is 60 minutes or 3600 seconds, the day which is the time needed for the sun to return to its highest in the sky or about 24 hours, the week which is a period of 7 days, the month which is based originally on orbital period of the moon and varies from 28-31 day and the year which is based on the orbital period of the Earth as it moves around the Sun and is a period of 365.2596 days. The week is the only time unit not based on an astronomical period being based on the Jewish Sabbath cycle which is based on the creation week of Genesis 1. The calendar year is rounded to 365 days with a leap day every 4 years.

According to Special and General Relativity time is a 4^th dimension. It is unique in that we only travel through time one way. (forward).

Time is one of the three main parts of the Universe: space, time and mass. Relativity shows them to be inter-related with space and time are so interrelated that they form a single entity.  Mass warps space-time forming gravity and motion of mass contracts both space and time.

The perception of the rate of time is variable but time is always experienced in the same way. We remember the past, we exist in the present and we look forward to the future. In our common experience time is the sequence of events we experience. Physics has shown that it is to be a lot more. It is a fundamental part of the universe.
