Big Bang Theory
The big bang Theory, is a theory scientist all believe is the explanation to how the universe began. The theory states, all matter in the universe was concentrated into a single tiny point. 13.7 billion years ago the bi bang theory happened. Before The Big Bang Theory universe started off with no stars, atoms, form or structure.

Law of Planetary Motion
Johannes kepler made the law of Planetary Motion. Planetary Motion law states that all planets move about the sun in elliptical orbits, having the sun as one of the foci. This Law being published in 1609. 2nd law is The line connecting the sun to a planet sweeps equal areas in equal times. 3rd law is that the square of the orbital period of the planet is proportional to the mean distance from the sun.

Law Of Motion
Newtons 1st Law Sometimes referred to as the law of Inertia An Object at rest stays at rest and an object in Motion stays in Motion unless acted upon by an unbalanced force. 2nd law stating the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force. 3rd law is for every action there is an equal and opposite reaction. Meaning in every interaction there is a pain of forces on the two objects interacting.

Law Of Gravity
The law of gravity created by Isaac Newton on July 5th 1687.Law of Gravity states that a particle attracts every other particle in the universe using a force that is directly proportional to the product of their masses. Also Inversely proportional to the square of the distance between their centers. Newton was able to come up with the Law of Gravity well-scientist believe he saw an apple fall off a tree while he was thinking of the forces of Nature.

The Cell Theory
The cell theory originally created by Theodor Schwann and Mtthias Jakob Schleiden. They believe All living things are made of cells. Plus, that cells are the basic units of structure and function in living things. Also that Living cells come only from other living cells. As Microscopes improved Hooke and Leewenhoek continued their woek learning more about cells. Although "Then Cell Theory" is still a theory till this day.

Natural Selection Theory
Charles Darwin was a British naturalist who discovered "Natural Selection theory" a.k.a "Evolution Theory". On the HSM Beagle he was exploring the Galapagos Islands when he made his theory. Which states More individuals are produced each generation that can survive. Phenotypic Variation exists among individuals and the variation is heritable. Those Individuals with heritable traits better suited to the environment will survive. [Link Text](www.google.com) -
Law of Thermodynamics
The 1st law of Thermodynamics created by Rudolf Clausius and Wiliam Thomas States that energy can not be created nor destroyed it can only change form or be transferred from one object to another.2nd law is entropy that it will either increase or remain the same.3rd law is the entropy of a perfect crystal at absolute zero is exactly equal to zero.4, temp If 2 systems are in thermal equilibrium with a 3rd system they are in thermal equilibrium with each other.

Law of Independent Assortment
Law of Independent Assortment created by Gregor Mendel, all started off by him asking a question. Mendel wanted to predict the inheritance of 2 characteristics associated with 2 different genes. Whether they "stick together" or ignore one another. Later on came his law stating that the allele a gamate receives for one gene does not influence the allele received for another gene.

Speacial Relativity Theory
The special Relativity theory is one of Albert Einstiens created on September 26th 1905. His theory Determined the laws of physics are the same for all non accelerating observers. Also he showed that the speed of light within a vacuumis is the same. No matter the speed at which an observer travels.

Plate Tectonics Theory
The theory of Plate tectonics created by Alfred Wegner developed from 1950's-1970's. This theory stating that the outer rigid layer of the earth which is the lithosphere. Is divided into a lot of plates that move around across the earths surface Relative to each other like slabs of ice on a lake. Basically describing how the continents are separating from one another.
