- 16. GREEK PHILOSOPHERS (5TH– 3RD CENTURY B.C.E) • ANAXAGORAS – “PRIMORDIAL UNIVERSE” –ACCORDING TO HIM, UNIVERSE IS MADE UP OF DIFFERENT MIXTURE OF ALL INGREDIENTS IN A SMALL FRAGMENT. –MIXTURE WAS SET IN MOTION CALLED “NOUS” OR MIND. –THIS WHIRLING MOTION SHIFTED AND SEPARATED THE INGREDIENTS ON COSMOS OF SEPARATE MATERIAL OBJECTS.
- 17. GREEK PHILOSOPHERS (5TH– 3RD CENTURY B.C.E) LEUCIPPUS AND DEMOCRITUS • “ATOMIC UNIVERSE” • THEY STATED THAT UNIVERSE IS COMPOSED OF VERY SMALL, INDIVISIBLE AND INDESTRUCTIBLE ATOMS.

- 20. MODERN PHILOSOPHERS • RENEDESCARTES – THE VACUUM OF SPACE WAS NOT EMPTY AT ALL BUT WAS FILLED WITH MATTER THAT SWIRLED AROUND – HIS MODEL INVOLVED A SYSTEM OF HUGE SWIRLING WHIRLPOOLS OF FINE MATTER PRODUCING WHAT WOULD LATER BE CALLED GRAVITATIONAL EFFECT.
- 21. MODERN PHILOSOPHERS • ISAACNEWTON – DESCRIBED THE UNIVERSE AS A STATIC, STEADY- STATE INFINITE UNIVERSE. (PRINCIPIA BOOK) – MATTER ON THE LARGE SCALE IS UNIFORMLY DISTRIBUTED AND THE UNIVERSE IS GRAVITATIONAL BALANCED BUT ESSENTIALLY UNSTABLE.
- 22. MODERN PHILOSOPHERS • ALBERTEINSTEIN – EXPLAINED THE UNIVERSE BY HIS THEORY OF RELATIVITY THAT HAS A SAME THOUGHT WITH ISAAC NEWTON. – ADDED A COSMOLOGICAL CONSTANT TO HIS GENERAL THEORY OF RELATIVITY EQUATIONS TO COUNTERACT THE DYNAMICAL EFFECTS OF GRAVITY, WHICH WILL BE CAUSED OF THE UNIVERSE TO COLLAPSE.
- 23. MODERN PHILOSOPHERS • EDWINHUBBLE – 1929, SHOWED THAT UNIVERSE WAS NOT STATIC THROUGH HIS TELESCOPE.
- 24. MODERN PHILOSOPHERS • ARNOPENZIAS AND ROBERT WILSON – 1965, DISCOVERED THE COSMIC MICROWAVE BACKGROUND RADIATION. – THE BIG BANG THEORY HAS BEEN THE MAINSTREAM SCIENTIFIC VIEW.
- 25. MODERN PHILOSOPHERS • GEORGEHENRI JOSEPH EDOUARD LEMAITRE – BIG BANG THEORY (1927) – THEORY DESCRIBES THE UNIVERSE AS ORIGINATING FROM AN INFINITELY TINY, INFINITELY DENSE POINT OF SINGULARITY BETWEEN 13 – 14 BILLION YEARS AGO. THE OSCILLATING UNIVERSE FOLLOWED GENERAL THEORY OF RELATIVITY EQUATIONS OF THE UNIVERSE WITH POSITIVE CURVATURE. THIS CURVATURE RESULTS IN THE UNIVERSE EXPANDING FOR A TIME AND THEN CONTRACTING DUE TO PULL OF ITS GRAVITY IN A PERPETUAL CYCLE OF BIG BANG FOLLOWED, IN TIME, BY BIG CRUNCH.

- 31.
- 32. BUFFON’S COLLISION THEORY •GEORGE LOUIS LECLERC, COMTE DE BUFFON – PROPOSED THAT THE PLANETS WERE FORMED BY THE COLLISION OF THE SUN WITH A GIANT COMET. – THE RESULTING DEBRIS FORMED INTO PLANETS AND REVOLVED AROUND THE SUN
- 33. BUFFON’S COLLISION THEORY Collisionof Sun and a Giant Comet Debris from the collision Planets are formed Planets revolved around the sun

- 35. KANT – LAPLACENEBULAR THEORY Great cloud of gas and dust Collapse due to rapid spinning Turn into a pancake-shaped object These bulges becomes the sun and planets
- 36. KANT – LAPLACENEBULAR THEORY • MAJOR FLAWS. • IT ASSUMED THAT THE TOTAL ANGULAR MOMENTUM OF THE SYSTEM IS IN THE SUN, WHICH IS NOT THE CASE. ONLY 0.5% OF THE TOTAL ANGULAR MOMENTUM WAS CONTAINED IN THE SUN’S SPIN. THE REMAINDER WAS IN THE PLANETARY ORBIT.
- 37. JEAN’S – JEFFREY’STIDAL THEORY JAMES HOPWOOD JEANS AND HAROLD JEFFREYS THE PLANETS WERE FORMED FROM THE SUBSTANCE THAT WAS TORN OUT OF THE SUN. AS A SPEEDING MASSIVE STAR PASSED
- 38. JEAN’S – JEFFREY’STIDAL THEORY Speeding massive star passed near the sun. Pulled of sun materials due to gravitational attraction. The torn off materials subsequently condensed to form the planets.
- 39. SOLAR NEBULAR THEORY •SOLAR SYSTEM WAS FORMED AS A RESULT OF THE CONDENSATION AND OF HYDROGEN GAS AND DUST (INTERSTELLAR GAS AND DUST CLOUD). THERE IS AN EXPLOSION OF A STAR (SUPERNOVA) MIGHT HAVE CAUSED THE DUST AND GAS CLOUD TO COLLAPSE FORMING THE SUN AND PLANET.
- 40. SOLAR NEBULAR THEORY CONDENSATIONOF HYDROGEN GAS AND DUST. An explosion of a star (supernova) might have caused the dust and gas to collapse. Contraction converted gravitational energy into heat energy and caused the center to glow.
- 41. SOLAR NEBULAR THEORY:STAGES OF FORMATION OF PLANETS ACCRETION OF THE GRAIN- SIZED PARTICLES TO FORM CENTIMETER-SIZED PARTICLES WHICH WOULD LATER GROW TO SEVERAL KILOMETERS IN A DIAMETER. The formation of more massive objects from coalescing planetesimal. The massive objects are referred as protoplanets would later become planets.
