2. STEADY STATE THEORY
• steady state Theory was first
proposed by Sir James Jeans( 1920)
and again revised from in by Sir
Hermann Bondi and Thomas Gold (
1948).
It was further develop by Sir Fred Holyle to deal
with problems that had arisen in connection
with the alternative BigBang Hypothesis.
3. •This theory acknowledge
that change takes place
on smaller
•This theory acknowledge that change
takes place on smaller scale
•Proposed that new starts are
continually created at all time at the
rate needed to replace the stars which
have used up their fuel and have
stopped shinning.
4. •Adhering to the perfect cosmological
principle that asserts that the
observable universe is basically the
same at any time as at any place.
•Proposed as an alternative to the
BigBang Theory.
6. Steady State Theory
•has been discarded due
to contradiction in newer
observations.
•The universe has no
beginning or end in
time;and from any point.
BigBang Theory
• most widely
cosmological theory of
early foundation of the
universe.
•Starts from a single point
and form singularity then
it expand continuously.
7. •its expanding, but the
distances between
matters increasing on very
small scale.
•alos expanding, all
matter are moving away
from each other.
10. RADIO TELESCOPE
OBSERVATION
This observation were
saying that there more
cosmic radio sources
billion years ago that
there there are now. This
would suggest that the
universe is changing over
the time which contradict
the theory.
11. DISCOVERY OF QUASAR
Bright objects but are
very small, only found
at great distance us.
Light from them was
from us. Light from
them was emitted
billions of light year
ago.
12. COSMIC MICROWAVE
BACKGROUND
This is a weak background
radiation which fills the
whole space and is the same
in all directions.
In the Steady state Theory it
is almost impossible to
explain the origin of this
radiation.
