Dinosaur extinction theory (65 MYA)
A massive asteroid hit the earth at the Peninsula in Mexico about 65 million years. It is thought that the impact would have caused massive damage, including a giant dust cloud which lead to massive changes in the climate. This would have destroyed lots of the cretaceous plants, so herbivorous dinosaurs starved and the meat eating ones were left with nothing to eat either. http://www.nationalgeographic.com/science/prehistoric-world/dinosaur-extinction// -

Law of Cosines (15th Century)
The law of cosines for calculating one side of a triangle when the angle opposite and the other two sides are known. Can be used in conjunction with the law of sines to find all sides and angles. This law is mostly used during math. http://hyperphysics.phy-astr.gsu.edu/hbase/lcos.html -
Gravity Law (1665)
Newton's law of universal gravitation states that a particle attracts every other particle in the universe using a force that is directly proportional to the product of their masses and proportional to the square of the distance between their centers. but that two objects attract each other with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between them. https://en.wikipedia.org/wiki/Newton%27_law_of_universal_gravitation -
Spontaneous Generation Theory (1668)
The supposed production of living organisms from nonliving matter, as inferred from the apparent appearance of life in some supposedly sterile environments. A 17 century recipe for the spontaneous production of mice required placing sweaty underwear and wheat in an open-mouthed jar, then waiting for about 21 days, during which time it was alleged that the sweat from the underwear would penetrate the wheat, changing them into mice. https://www.britannica.com/science/spontaneous-generation -
Law of acceleration (1687)
Newton's second law of motion can be formally stated as the acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction and inversely proportional to the mass of the object.

Law of conservation of mass (1785)
The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass.

Cell Theory (1805)
In biology, cell theory is a scientific theory which describes the properties of cells. These cells are the basic unit of structure in all organisms and also the basic unit of reproduction. With continual improvements made to microscopes over time, magnification technology advanced enough to discover cells. https://en.wikipedia.org/wiki/Cell_theory -
Evolution Theory (1859)
A theory of biological evolution mainly developed by Charles Robert Darwin stating that all species raised and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce offsprings .

Law of octaves (1865)
Law of octaves, in chemistry, the generalization made by the English chemist J.A.R. Newlands in 1865 that, if the chemical elements are arranged according to increasing atomic weight, those with similar physical and chemical properties occur after each interval of seven elements. https://www.britannica.com/science/law-of-octaves. -
Big Bang (1955)
A theory that states the birth of the universe (big bang) from the observed expansion of the universe, cosmic background radiation, abundance of the elements, and the laws of physics. Scientists say a big bang ocurred and thats when life was made. http://umich.edu/~gs265/bigbang.htm
