In this topic you will know the origin of the earth and the theory behind the universe. And the differences between Big Bang, Steady state , Pulsating Universe and Big crunch states. You will know as well if there is a similarities between the four theory.

1. UNIVERSE

2. WHAT IS UNIVERSE?
The Universe is also called cosmos contains all
galaxies, stars, planets and all other forms of matter
and energy.
The largest scale galaxies are distributed uniformly
and the same in all directions, meaning that the
universe has neither an edge nor a center.

3. WHAT IS MILKY WAY ?
 It is where our solar system
located, which is one of
many galaxies in the
universe
 There is 51 galaxies that
have been discovered but
there an estimated number
of about 100 to 200 billion
all

4. COSMOLOGY
• What is cosmology?
• It is the branch of science
that studies the origin,
evolution an fate of the
universe.

5. WHAT ARE THE THEORIES BEHIND THE
ORIGIN OF THE UNIVERSE?
 BIG BANG
 STEADY STATE
 PULSATING UNIVERSE
 BIG CRUNCH STATE

6. WHAT IS BIG BANG ?
 The leading explanation
about how the universe
began.
 In this theory , energy and
matter divided and become
distinct from each other.
 It describe how the
Universe most possibly
began.

7. WHAT IS STEADY STATE?
 It is the states that the
universe ha been present
ever since and therefore has
no beginning and no end.
 According to this theory,
the density of matter in the
expanding universe remains
unchanged due to a
continuous creation of
matter.

8. WHAT IS PULSATING UNIVERSE?
 Pulsating Universe
combines both the Big Bang
and Big Bang Crunch as a
part of a cyclic event.
 In this theory , which
commonly known as the
oscillating or cyclic universe
theory.

9. WHAT IS BIG BANG CRUNCH STATES?
 It states at a certain point
in time, it will stop
expanding and collapse into
itself, pulling everything
with it until it eventually
turns into the biggest black
hole.
 It is describe on how the
Universe will end as a
consequence of the
beginning.

10. The end.
