The Universe and The Solar System Flashcards
One of the books of the Hebrew Bible and Christian Old Testament
Genesis
The current accepted model on the formation of the universe; describes the universe as expanding, having originated from an infinitely tiny dense point
Big Bang Theory
What are the three hypotheses on the formation of the Solar System?
Encounter Hypothesis, Nebular Hypothesis, and Protoplanet Hypothesis
What Latin word did “Universe” originate from?
Universus
Discovered the Cosmis Microwave Background Radiation
Arno Penzias and Robert Wilson in 1965
What comes into your mind when you hear the word universe?
star systems, galaxies, gas, and dusts; including matter and energy
The present working model on the formation of the Solar System; the Solar System began with a fragment from an interstellar cloud composed mainly of gasses
Protoplanet Hypothesis
States that about 5 billion years ago, a rogue star passed close to the sun and stripped materials from both the sun and the rogue star
Encounter Hypothesis
The form that the overall composition of the universe transitioned from light elements to solid particles
Nebula
Observed the galactic red shifts in 1929
Edwin Hubble
Albert Einstein’s favored model; follows the genral theory of relativity equations of the universe with positive curvature
The Theory of Oscillating Universe
Pure energy compressed in a single point
Singularity
To whom was the fundamental statement of the Big Bang Theory attributed to?
Belgian Catholic priest Georges Lemaitre in 1927
What is the study of the universe?
Cosmology
Proposed the Steady State Theory
Fred Hoyle, Thomas Gold, and Hermann Bondi
What award did Penzias and WIlson earn?
Nobel Physics Prize in 1978
What is the age of the Solar System and the planet Earth based on?
Age of meteorites
Creator of The Theory of Oscillating Universe
Albert Einstein
When did the Big Bang Theory’s universe come to exist?
14 billion years ago
Those who stated the Nebular Hypothesis
Emanuel Swedenburg, Immanuel Kant, Pierre-Simon Laplace
A phenomenon where electromagnetic radiation from an object undergoes an increase in wavelength
Redshift
What are the four theories of how the universe originated?
The Theory of Creation, The Theory of Oscillating Universe, Steady State Theory, and Big Bang Theory
What is the age of the Solar System and the planet Earth?
4.54 billion years old
Describes how God separated light from darkness, created the sky, land, sea, moon, stars, and every living creature in a span of six days
The Theory of Creation
Predicts a universe that expanded but did not change its density
Steady State Theory
States that the entire solar system started as a large cloud of gas that contracted due to self-gravity
Nebular Hypothesis
What did the Nebula later form?
Star systems and Planets known today
When did the galaxies begin to form after the universe?
After one billion years
What did the solar nebular eventually form?
The Sun
What does Universus mean?
combined into one
When did the universe begin with the big bang?
13.8 billion years ago
What was the Encounter Hypothesis able and unable to explain?
Able to explain why inner planets are denser than the outer ones, unable to explain how lumps of hot gases contract to form planets
What are the Outer Planets?
Jupiter, Saturn, Uranus. Neptune
When did stars and galaxies begin to form?
After 100 million years
What are the Inner Planets?
Mercury, Venus, Earth, Mars
