The Light of Creation

Genesis 1:3-5
3. And God said, Let there be light: and there was light.
4. And God saw the light, that it was good: and God divided the light from the darkness.
5. And God called the light Day, and the darkness he called Night. And the evening and the morning were the first day.

This light mentioned above could not have come from the sun because the sun did not yet exist. There are several observations to make about this light. The first is that this light had no source but was created in space by God. This light came from every direction in space as indicated by the need to separate out darkness to make night. This could have been accomplished by use of a dark cloud to block light on one side.

Astronomers have observed this type of light. A light coming from every direction without any observable source, in the form of the Cosmic Background Radiation. (CBR) While this is microwave radiation and not visible light, an expansion factor for the universe of 3300 (from 4.1 million to 13.5 billion Light Years) would convert the visible light to microwaves. This is a much smaller expansion than required by the Big Bang model so it is quit possible.

Note the phrase in verse 5, “The evening and the morning were the first day”. This clearly shows that the days of Creation were normal Earth days.

The Work of Energy

Energy is the ability of a system to do work. Special Relativity shows that energy has mass and that the mass all matter is a result of energy, so that all substance is based on energy.

The 1st Law of Thermodynamics states that the energy in any interaction is conserved. The result is that is the total amount of energy in the universe is constant. It is also stated as energy can not be created or destroyed but it can change forms.

Below is a list of common types of energy
  1. Heat energy is the energy associated with the temperature of an object.
  2. Light energy is the energy associated with visible light.
  3. Electrical energy is the energy associated with an electric current.
  4. Chemical energy is the energy associated with the reactions involving molecules.
  5. Nuclear energy is the energy associated with reactions involving atomic nuclei.
  6. Kinetic energy is the energy associated with motion.
  7. Potential energy is the energy of a system based on its position or condition. Stored energy.
  8. Rest mass energy id tThe energy of an object that is not in motion. E= mc2
Energy is one of the three main parts of the Universe space, time and mass and relativity shows them to be inter-related. Space and time are so interrelated that they form a single entity. Furthermore mass warps space-time forming Gravity and the motion of mass contracts both space and time. 

In conclusion in common experience energy is what moves us and allows us to move thing. Physics has shown it to be a lot more. It 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.
