Study Notes
Creation Theories
- God as the Supreme Being is believed to have created the universe from nothing, as described in the Holy Bible.
- The Big Bang Theory proposes that the universe began about 13.8 billion years ago, starting from a singularity.
Big Bang Theory
- The universe's expansion can be likened to bread with raisins; the bread represents the universe while the raisins depict galaxies.
- Galaxies recede from each other, indicating an expanding universe where matter dilutes over time.
- Light elements such as hydrogen (H), helium (He), and lithium (Li) formed from nucleosynthesis shortly after the Big Bang.
- The Cosmic Microwave Background (CMB) radiation is crucial evidence of the Big Bang, discovered by Arno Penzias and Robert Wilson.
Limitations of the Big Bang Theory
- It does not explain the origin of the universe or the formation of galaxies; it only describes their evolution.
- As the universe expands, new stars and galaxies form while older ones become unobservable due to distance.
- Despite expansion, the universe's average density remains constant, indicating a steady state.
Steady State Theory
- Proposed in 1948 by Herman Bondi, Thomas Gold, and Fred Hoyle, this theory suggests the universe is eternal, creating new matter as it expands.
- It contradicts the law of conservation of energy and mass.
- The discovery of CMB radiation in 1965 led to the rejection of this theory as it could not account for the uniform radiation detected in all directions of the universe.
Oscillating Universe Theory
- Also called the pulsating theory, it suggests that the universe expands and contracts cyclically, leading to the formation of singularities and new universes (big bounce) after each cycle.
- Proposed by Richard Tolman, this theory faces challenges due to dark energy's role in current cosmic understanding.
Nebular Theory
- Widely accepted model of solar system formation, suggesting it originated from a nebula approximately 4.5 billion years ago.
- A nebula consists of gas and dust, which collapses under gravity to form a protoplanetary disk and eventually planets.
Steps in Solar System Formation
- Occurs through cloud collapse, formation of a protoplanetary disk, and growth of planets.
- Metals and silicates concentrated near the Sun enabled the creation of terrestrial planets: Mercury, Venus, Earth, and Mars.
Challenges to Nebular Theory
- Issues arise such as why the Sun does not spin faster than other planets and the unusual rotations of Uranus and Venus.
- Encounter Theory posits that planets formed from material ejected from the Sun during interactions with other celestial bodies.
Planetesimal Theory and Tidal Theory
- The Planetesimal Theory, proposed by Thomas Chrowder Chamberlin, suggests planets formed from solid particles rather than gas or liquid.
- Tidal Theory, proposed by James Jeans and Harold Jeffreys, posits that a near-collision with a passing star resulted in planet formation from condensed gas.
- Both theories have limitations; for example, the hot material cannot contract, which would hinder the formation of planets.
