theories about the origin of the Universe and the Solar System

1. UNIVERSE AND SOLAR
SYSTEM

2. Learning Competencies:
*State the different theories explaining the
origin of the universe.
*Describe the different theories explaining
the origin of the solar system.

3. *Think about it..
*Suppose you meet an alien and asks you to
describe Earth, your home. How will you
describe Earth?
*Suppose the alien further asks the origin and
history of your home and where it came
from, can you confidently answer the
question?

4. FACT
OR
BLUFF

5. *FACT
*THE UNIVERSE AS WE
CURRENTLY KNOW IT ALL
COMPRISES ALL SPACE AND
TIME AND ALL MATTER AND
ENERGY IN IT.

6. *BLUFF
*THE UNIVERSE IS AT LEAST
4.5-4.6 BILLION YEARS OLD.

7. *FACT
*ACCORDING TO CLAUDIUS
PTOLEMY, THE EARTH IS THE
CENTER OF THE SOLAR SYSTEM.

8. *BLUFF
*THE SUN IS THE CENTER OF
THE UNIVERSE

9. *FACT
*EARTH IS THE ONLY PLANET IN
THE SOLAR SYSTEM WITH
PROPERTIES NECESSARY TO
SUPPORT LIFE.

10. ORIGIN OF THE UNIVERSE
*What is your idea about the
beginning of the universe?

12. Cosmology - is the study of
the universe, including its
properties, structure and
evolution.

13. Universe
* derived 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

14. *
*Evolutionary or evolving universe theory
*All matter and energy of space are compressed in a
primordial core. Billion years ago, this primordial core
exploded.
*Immediately, after the explosion, the early universe is
composed of intense radiation and particles.
*The intense radiation, together with some matter,
formed a rapidly expanding region called the primordial
fireball.
*In time, the matter broke apart into huge clumps.
*The clumps became the galaxies.
*Smaller clumps within the galaxies formed stars.

16. *
*Proposed by Alan Guth, Andrei Linde, Paul
Stein Hart, and Andy Albrecht
*Basically, cosmic inflation is the
hypothesis that, immediately after the big
bang, the universe expanded very, very,
very rapidly - much faster than the speed
of light. A fraction of a second later, this
rapid expansion slowed, and the universe
continued to expand, but at a much
slower rate.

18. *
*The universe is expanding and has an infinite age.
*Infinite Universe Theory or Continuous Creation
*Proposed by Hermann Bondi, Thomas Gold, And Sir Fred
Hoyle
*The universe has no beginning or end.
*The universe is in the process of constant creation and the
matter is being continually replenished in one place and
being destroyed elsewhere.
*Believes that as galaxies move apart, new matter appears
between them and forms new galaxies.
*As new galaxies form, old ones die, with the universe
always having the same density.

20. *
*According to the
Genesis of the
Bible’s Old
testament, the
creation of the
entire cosmos
(universe) took
place in six days.
The biblical
creation story tells
that God created
the universe.

21. *7 DAYS OF CREATION
*Day 1 - God created light and separated the
light from the darkness, calling light "day"
and darkness "night."
*Day 2 - God created an expanse to separate
the waters and called it "sky."
*Day 3 - God created the dry ground and
gathered the waters, calling the dry ground
"land," and the gathered waters "seas." On
day three, God also created vegetation
(plants and trees).

22. *Day 4 - God created the sun, moon,
and the stars to give light to the earth
and to govern and separate the day and
the night. These would also serve as
signs to mark seasons, days, and years.
*Day 5 - God created every living
creature of the seas and every winged
bird, blessing them to multiply and fill
the waters and the sky with life.

23. *Day 6 - God created the animals to fill the
earth. On day six, God also created man
and woman (Adam and Eve) in his own
image to commune with him. He blessed
them and gave them every creature and the
whole earth to rule over, care for, and
cultivate.
*Day 7 - God had finished his work of
creation and so he rested on the seventh

26. *How did the solar system
and its life forms originate
from something that is
very hot and very small?
ORIGIN OF THE SOLAR SYSTEM

27. *
*Proposed by Immanuel Kant and Pierre-Simon
Laplace
*Kant-Laplace Nebular Hypothesis
*A great cloud of gas and dust, called nebula, begins
to collapse because of gravitational pull.
*As the cloud contracted it spuns more rapidly.
*Spinning cloud flattens into a pancake-shaped object
with a bulge at the center.
*As nebula collapses further, local regions contract on
their own due to gravity.
*These local regions become the sun and the planets.

29. *
*Proposed by Thomas Chowder Chamberlin and
Forest Ray Moulton
*The collission of a star created huge tides on the
surface of our sun that resulted to erupted matter.
*The cross-pull from the star was thrust into
elliptical orbits around the sun.
*The smaller masses quickly cooled to become solid
bodies called planetesimals.
*As their orbits crossed, the larger bodies grew by
absorbing the planetesimals, thus becoming
planets.

31. *
*Proposed by Sir James Hopwood Jeans’ and
Harold Jeffreys
*Planets were formed from the substance that
was torn out of the sun.
*As a speeding massive star passed near the
Sun, it pulled off material due to gravitational
attraction.
*The pulled off material subsequently
condensed to form the planets.

system

38. *
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.

39. *
*1. Do you think there are other life
forms exploring the universe aside
from humans? Why or why not?
*2. If the universe is expanding, does
that mean earth is also increasing its
distance from the sun? Will this
possibility affect the sustainability of
life on earth?
