ORIGIN OF THE UNIVERSE Flashcards
(35 cards)
*To make sense, humans use religion, traditions, philosophy, and science to describe its origin and structure
*Understanding Universe: built upon previous knowledge and enhanced by upgrading techniques
ORIGIN OF THE UNIVERSE
10 ORIGIN OF UNIVERSE, EARTH, SUBSYSTEMS
1 | BOOK OF GENESIS
2 | RIGVEDA (A HINDU TEXT)
3 | PRIMORDIAL UNIVERSE
4 | ATOMIC UNIVERSE
5 | GIANT BODY
6 | GEOCENTRIC UNIVERSE
7 | HELIOCENTRISM THEORY
8 | INFINITE UNIVERSE:
9 | CARTESIAN VORTEX MODEL:
10 | STATIC UNIVERSE:
oscillating universe contained in cosmic egg “Brahmanda”
2 | RIGVEDA (A HINDU TEXT)
God separated light from darkness and created everything in span of 6 days
1 | BOOK OF GENESIS
mixture of small fragments, not entirely uniform, to produce cosmos, set in motion by action of “Nous” or mind
3 | PRIMORDIAL UNIVERSE:
stoic philosophers believed Sun and stars are most important | everything else was interconnected (You are a star.)
5 | GIANT BODY
Leucippus and Democritus - universe is composed of tiny, indivisible, indestructible atoms (lacks facts/research)
4 | ATOMIC UNIVERSE:
Aristotle and Ptolemy proposed Earth stayed motionless in heavens and everything was revolving around it (center)
6 | GEOCENTRIC UNIVERSE:
*debunked geocentric
*1543, Nicolaus Copernicus: Earth and other planets revolved around a star.
*1584, Giordano Bruno: solar system is not the center of the universe
7 | HELIOCENTRISM THEORY
Big Bang Theory 1687, Isaac Newton: matter on large scale is uniformly distributed, balanced gravity, unstable
8 | INFINITE UNIVERSE
Rene Descartes outline based on Newton’s infinite universe: vacuum of space with matter swirled around in large and small vertices (Gravitational Effects)
9 | CARTESIAN VORTEX MODEL
*Albert Einstein: universe was static, dynamically stable universe, neither expanding nor contracting
*1929 Edwin Hubble disproved this theory
10 | STATIC UNIVERSE:
4 FUNDAMENTAL FORCES IN FRACTION
GRAVITY:
ELECTROMAGNETIC FORCE
STRONG NUCLEAR FORCE
WEAK NUCLEAR FORCE:
*Universe is expanding, originated from infinitely tiny dense point, reason for inflation of the universe
extremely hot; matter not exist
*Matter: not present but only pure energy compressed in single point (singularity)
*Attributed to Belgian Roman Catholic priest, George Lemaitre in 1927
*Supported by demonstration of Edwin Hubble, continuously expanding universe
THE BIG BANG THEORY
attraction between bodies
GRAVITY
binds atom into molecule
ELECTROMAGNETIC FORCE
TIMELINE 3
After 300 million years, stars and galaxies began to form as Hydrogen & Helium coalesce with aid of gravity
break down atom’s nucleus and produce radioactive decay
WEAK NUCLEAR FORCE:
TIMELINE 2
About 300,000 years, About 300,000 years, temperature cools for hydrogen & helium to form completely
- Photons escaped - light existed
binds proton and neutron in nucleus
STRONG NUCLEAR FORCE:
TIMELINE 1
After 3 mins. universe continuously expanding, it began to cool down allowing protons & neutrons of hydrogen and helium
*Pathways by which chemical substance moves through biotic and abiotic components of Earth
*Allows circulation of important chemical nutrients to support life and maintain balance of substances through the biological and physical world (Food Chain)
BIOGEOCHEMICAL CYCLE
3 ORIGIN OF SOLAR SYSTEM
1 | ENCOUNTER HYPOTHESIS
2 | NEBULAR HYPOTHESIS
3 | PROTOPLANET HYPOTHESIS
*After 5 billion years, rogue star passed closed to Sun and stripped materials from both Sun and rogue star
*Why all planets revolve in same direction
1 | ENCOUNTER HYPOTHESIS
