EARTH SCIENCE lesson 1.2 THEORIES

• In the book of Genesis, God separated light from darkness created the sky, land, sea, moon and stars in every living creature in a span of six days.
• In the Oscillating Universe, it Describes the universe and as an oscillating universe in which a “cosmic egg” or brahmanda containing the whole universe.
• The hindu text of the Oscillating Universe is the Rigveda
• in the Primordial Universe, the original state of cosmos was a primordial mixture.
• Anaxagoras was the first to give a correct explanation of eclipses
• Anaxagoras was the philosopher who made the theory of the Primordial Universe
• In the Primordial Universe, The theory states that if energy is added to the gases that made up Earth's early atmosphere, the building blocks of life would be created.
• In the Primordial Universe, The mixture of inorganic and organic compounds with water on the primitive Earth

  Ammonia

  Hydrogen Gas

  Hydrogen
• In the theory of Oscillating Universe, Rigveda is the oldest sacred books of hinduism
• The Oscillating Universe Theory states that the universe undergoes periods of expansion and contraction.
• Heterotropic theory - organisms that are dependable to light
• The book of Genesis is also called at The Creation Story
• According to Leucippus and Democritus, in the Atomic Universe, the basis for the atomic model is that the universe is made up of two fundamental elements:

  1. atoms - Building blocks of matter
  2. void - Empty space/Absence of matter
• In the atomic Universe, the Universe was composed of very small, indivisible and indestructible building blocks known as atoms.

  • Atoms are the smallest division of matter, making them indestructible and composing all physical objects.
• The Aristotelian Universe was Proposed by the Greek philosopher Aristotle.
• Aristotle in the Aristotelian Universe believed the Earth was round.
• Aristotle in the Aristotelian Universe, thought Earth was the center of the universe and that the Sun, Moon, planets, and all the fixed stars revolved around it (Geocentric)
• The Ptolemaic Universe theory was made by Cladius Ptolemaus
• In the Ptolemaic Universe, The model for the universe, put forth by the ancient Greek astronomer Ptolemy, that had the Earth at the center, with the sun, moon, planets, and stars revolving around it. (Geocentic Model)
• The Ptolemaic Universe was based on the theory of Aristotle
• Copernican Universe was made by Nicolaus Copernicus
• The theory of the Copernican Universe is the theory of Helocentric.
• The Newtonian Universe is also called as Static Universe
• The Newtonian Universe theory was created by Isaac Newton
• Isaac Newton in the Newtonian Universe published his "Principia" in 1687. which described, among other things, a static, steady state, infinite universe which even Einstein, in the early 20th Century, took as a given
• Cartesian Vortex Universe Theory was made by Rene Descartes.
• In the Cartesian Vortex Universe, it Outlines a model of the universe with many of characteristic of Newton started infinite universe
• In Descartes system (cartesian Vortex Universe), like Aristotle's, the universe was full of matter, there was no such thing as empty space. To explain motion Descartes introduced the concept of vortices. The system consisted of different kinds of mater or elements rubbing up against each other.
• Einsteinian Universe theory was made by Albert Einstein
• in the Einsteinian Universe, Einstein added the cosmological constant to his general theory of relativity equation to counteract the dynamic effects of gravity which would have caused the universe to collapse.
• The Big Bang Theory was made by Abbe Georges Edouard Lemaitre (1894-1966)
• In the Big Bang Theory, The Universe developed 13.8 billion years ago.
• Edwin Hubble discovered that the galaxies are moving away from each other.
• Oscillating Universe

  • Alberts Einstein favored Model
  • Followed the general theory of relativity equation of the universe.
• The Steady State Theory was Proposed by astronomers Fred Hoyle, Thomas Gold and Herman Bondi.
• In the Steady State Theory, the universe is constantly expanding but did not change its density
• The Inflationary Universe was made by American Physicist, Allan Gutch
• In the Inflationary Universe, the Universe underwent a short and sudden episode of great expansion right after the Big Bang.
• The multiverse was a theory made by American physicist Hugh Everret III and Bryce DeWitt in which it has multiple worlds
• The multiverse is a term that scientists use to describe the idea that beyond the observable universe, other universes may exist as well
