Several ancient religious texts and philosophers throughout history have proposed theories on the origin of the universe. The book of Genesis describes God creating the universe in six days, while the Hindu text Rigveda depicts an oscillating universe emerging from a single point. Early Greek philosophers proposed primordial theories of the original state being a mixture that separated, and an atomic universe composed of indivisible atoms. More recent scientists like Newton, Einstein and Hubble contributed models of static or expanding universes based on observations and equations. The prevailing theory today is the Big Bang, where the universe rapidly expanded from an infinitely dense point, though oscillating universe and multiverse theories also exist.

THEORIES ON THE ORIGIN OF THE UNIVERSE
HOW DID EVERYTHING IN THE UNIVERSE COME TO EXIST?
THE NARRATIVE FROM GENESIS •One of the books of Hebrew bible and Christian old testament, described how God separated light from darkness, created the sky, land , sea, moon, stars, and every living creature in a span of six days.
HINDU TEXT RIGVEDA •Describes the universe as an oscillating universe in which a “cosmig egg” or Brahmanda, containing the whole universe, expands out of single concentrated point called Bindu, and eventually collapse again.
PRIMORDIAL THEORY/ UNIVERSE •The Greek philosopher Anaxagoras believed that the original state of cosmos was a mixture of all ingredients, which existed in infinitesimally small fragments of themselves.
ATOMIC UNIVERSE •Belief of Greek philosophers Leuccipus and Democritus, that the universe was composed of very small , indivisible and indestructible atoms.
BELIEF OF STOIC PHILOSOPHER •Believed that the universe is like a giant living body, with the sun and the stars as the most important parts to which all the other parts are interconnected.
RENÉ DESCARTES UNIVERSE •His model involved a system of huge swirling whirlpools of fine matter producing what would later be called gravitational effects.
ISAAC NEWTON UNIVERSE •Published his Principia, which described a static, steady-state infinite universe. A universe with matter on the large scale is uniformly distributed and the universe in gravitationally balanced but essentially unstable.
ALBERT EINSTEIN UNIVERSE •Like Newton’s, It was static, dynamically stable universe, which was neither expanding nor extracting. •He added a cosmological constant to his general theory relativity equations to counteract the dynamic effects of the universe.
EDWIN HUBBLE UNIVERSE •The universe is not static. The universe is continuously expanding.
BIG BANG THEORY •This theory describes the universe as originating from an infinitely tiny, infinitely dense point or singularity.
Theories on the origin of the universe
OSCILLATING UNIVERSE •Was Einstein favored model after he rejected his own original model. •This theory followed the general theory of relatively equations of the universe with positive curvature.
STEADY STATE THEORY •Proposed by astronomer Fred Hoyle, Thomas Gold and Herman Bondi, predicted a universe that expanded but did not change its density; matter was inserted into the universe as it expanded in order to maintain a constant density.
INFLATIONARY MODEL •Alan Guth model based on Big Bang. He incorporated a short, early period of exponential cosmic inflation in order to solve the horizon and flatness problem of the standard Big Bang model.
•Another variation of the inflationary universe is the cyclic model developed by Paul Steinhardt and Neil Turok in 2002, incorporating the superstring theory
MULTIVERSE • Russian-American physicist Andrei Linde developed the inflationary universe with chaotic inflation theory in 1983. • This theory sees our universe as just one many “bubbles” that grew as part of multiverse. • Hugh Everett III and Bryce DeWitt initially developed popularized the “many worlds” formulation of the multiverse.
ASSIGNMENT •Fast Facts about the Solar System
