CHAPTER 1
Origin of the Universe
The study of materials and processes that operate beneath and upon Earth's surface. Geology
The study of our Earth. Earth Science
The study of the universe, planet's origin and members of solar sytem.
Astronomy
Study of composition and movements of seawater, coastal processes, seafloor, topography and marine life.
Oceanography
Study of atmosphere and elements that produce weather. Meteorology
Origin of the Universe Cosmology - is the study of the universe, including its properties, structure and evolution. 10-15 billion years ago - the universe began when the primordial explosion called Big Bang occured.
all energy and matter of the universe were compressed into hot and dense state big bang great quantities of helium and hydrogen created 3 millions later huge clouds began to condense 200 million years formation of galaxies
Examples of Galaxies •
Milky Way
•
Large Magellanic Cloud
•
Andromeda
•
Cigar Galaxy
•
Tadpole Galaxy
•
Sombrero Galaxy
•
Pinwheel Galaxy
Universe - derives from the Old French word univers, which in turn derives from the Latin word universum is all of space and time (spacetime) and its contents, which includes planets, moons, minor planets, stars, galaxies, the contents of intergalactic space and all matter and energy. sometime called cosmos geocentric ---- Nicolaus Copernicus ---- heliocentric mode
Theories on the Origin of the Universe Theories of the Origin of the Universe_low.mp4
BIG BANG THEORY All of the energy and matter of the universe were compressed into hot and dense state. About 13.7 billion years our universe began as a cataclysmic explosion, which continued to expand, cool and evolve its current state. Temperature decreased sufficiently to allow clumps of matter to collect. these materials formed the first nebulae, which evolved into the first stars and galaxies. Our sun and planetary system formed 5 billion years later.
CREATIONIST THEORY This theory states that God, the Supreme Being created the whole universe out of nothing. The proof can be read in the Holy Bible stipulating that God created the heaven and the Earth including man.
OSCILLATING UNIVERSE THEORY •
•
proposed by a Russian-born US cosmologist GEORGE GAMOW he said that the expansion of the universe will eventually come to a halt then it collapses up to the time that the universe will return to its original form and form another Big Bang wil occur. This process will happen as a cycle.
STEADY STATE THEORY
This theory states that the universe has always been the same since the beginning and will remain in its present state until eternity. It further claims that the new galaxies appear as a result of the drifting of other galaxies.
Our Expanding Universe
The universe is still expanding in a Doppler red shift in the light we receive. It shows an icreasing distance between us and other galaxies in the universe. It also shows that the universe is expanding slowly.
Evaluation
IDENTIFICATION 1. The study of the entire universe, 2. The widely accepted theory about the origin of the universe. 3. This theory states that the universe has always been the same and will continue to be the same forever. 4. This theory suggests that the universe expanded from a small ball and it is still expanding. 5. The other term for universe.
Answer the following: 1. How can you prove that the universe is expanding? 2. If you are to formulate your own theory about the origin of the universe, how would you explain it?
ASSIGNMENT Research on the other theories about the origin of thuniverse. Summarize their main assumptions.
