models/theories Flashcards
representation of ideas, an object or processes that is used to describe and explain phenomena that cannot be explained directly
models
describes how God brings the Universe into being in a series of creative acts over six days
Theory of Divine Creation
describes the universe as an oscillating universe
Hindu text Rigveda
cosmic egg that contains the whole universe
Brahmanda
he believed in primordial universe
Anaxagoras
they believed in an atomic universe
Leucippus and Democretus
they proposed a geocentric universe
Aristotle and Ptolemy
he made the theory of heliocentrism in 1543
Nicolas Copernicus
he suggested that the solar system is not in the center of the universe
Giordano Bruno
he described the universe as static, steady-state, infinite
Sir Isaac Newton
true or false: matter on the large scale is uniformly distributed, and the universe is gravitationally balance but essentially unstable
true
he outlined a Cartesian vortex model of the universe with many characteristics of Newton’s idea
Rene Descartes
a system of huge swirling whirlpools of fine matter
gravitational effects
he added a cosmological constant to Newton’s static and dynamically-stable universe
Albert Einstein
cosmological constant
gravity
he showed that the universe was not static
Edwin Hubble
this theory starts with the universe as a small singularity that inflated over the next 13.8 billion years to the modern cosmos
big bang theory
they demonstrated the continuously expanding universe through the observations of galactic redshifts
Edouard Lemaitre & Edwin Hubble
redshift
moving AWAY from the source
blueshift
moving TOWARDS the source
they discovered the cosmic microwave background radiation
Arno Penzias & Robert Wilson
IDENTIFY THE PLACEMENT OF THIS EVENT IN THE BIG BANG THEORY: the universe was extremely hot that matter did not exist.
1st
IDENTIFY THE PLACEMENT OF THIS EVENT IN THE BIG BANG THEORY:
four fundamental forces were formed… gravity, electromagnetic force, strong nuclear forces, and weak nuclear forces
2nd
IDENTIFY THE PLACEMENT OF THIS EVENT IN THE BIG BANG THEORY: universe continually expanded and began to cool down, allowing protons and neutrons to fuse and form hydrogen and helium
3rd
IDENTIFY THE PLACEMENT OF THIS EVENT IN THE BIG BANG THEORY: temperature became cool enough for hydrogen and helium atoms to form
4th
IDENTIFY THE PLACEMENT OF THIS EVENT IN THE BIG BANG THEORY: photons escape and light existed for the very first time
5th
IDENTIFY THE PLACEMENT OF THIS EVENT IN THE BIG BANG THEORY: stars and galaxies began to form because of the joining of hydrogen and helium with the aid of gravity
6th
IDENTIFY THE PLACEMENT OF THIS EVENT IN THE BIG BANG THEORY: transition from light to heavier elements
7th
IDENTIFY THE PLACEMENT OF THIS EVENT IN THE BIG BANG THEORY: formation of solid particles as the nebula
8th
IDENTIFY THE PLACEMENT OF THIS EVENT IN THE BIG BANG THEORY: nebula form the star system and planets known today
9th
author of the oscillating universe which follows the equations of the theory of relativity with positive curvature
Albert Einstein
authors of steady state theory
fred hoyle and hermann bondi
it predicted that a universe expanded but did not change its density-matter
steady state theory
author of inflationary universe and proposed model of universe based on big bang
Alan Guth
author of multiverse
Andrei Linde
