Basics of Relativity Theory

 

Basic Relativity

 

Contrary to what it commonly thought Relativity theory was not invented by Einstein but the basic concept was actually developed by Galileo. Einstein realized that not only was motion was relative but time, mass and space were relate as well as well.

 

In Galilean Relativity space and time were seen as absolutes. This was a result of Galileo not considering the speed of light in his thinking because was unable to measure it. In fact Galileo tried measure the speed of light being the first recorded person to have tried to do so.

Newton’s laws of motion were partly based on Galilean Relativity. These laws formed the foundations of physics. However it was ultimately the failed attempt to detect the aether that led to Einsteinian relativity.

From here Einstein developed both his Special and General Relativity. Though Relativity had been used in the development of atheistic theories like the Big Bang, it has also been of great use to Creation Science Cosmology.



In the beginning

Genesis 1:1

In the beginning God created the heaven and the earth.

This is the first verse of the Bible, it is important to note that God is assumed to exist and he is designated as the first cause from which all affects come. Mentioned in this verse are the three main components of the universe space (the heaven), mater (the Earth), and time (the beginning).

In physics, relativity theory shows that space, matter (energy) and time are interrelated parts of the universe such they can not exist separately. It also shows that time is an integral property of the universe that can have a beginning. Furthermore the beginning of time must coincide with the beginning of space and matter and Genesis 1:1 is consistent with this.

Cosmology the Science of the Universe

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

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

Edwin Hubble discovered the expansion of the Universe 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 (CBR) is the thermal black body spectrum that is nearly uniform in every direction, It represents a temperature of 2.725 K in that it peaks 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 establishment Cosmology. 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 plasma universe which depicts much of the phenomenon in universe as being electrical in nature. It is not yet fully developed.  

Creationist Cosmologies are 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.

Matter in Physics

Matter:is anything that has mass and occupies volume. It is the general term for the substance of which all physical objects are made. Mass is 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 is the resistance of a body to acceleration when responding to force. Gravitational Mass is  the 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.

There are three 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. Solids have a definite volume and definite shape. Liquids have a definite volume but no definite shape. Gas has no definite volume or shape. Plasma is commonly called the fourth 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 Just Nothing

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

Often illustrated by 3 lines representing the three dimensions of space the linese 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. 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.
