Steady state theory

Steady State Theory

1. STEADY STATE THEORY

2. Steady State Theory was first proposed by Sir James Jeans (1920) and again revised from in by Sir Hermann Bondi and Thomas Gold (1948).

3. It was further developed by Sir Fred Hoyle to deal with problems that had arisen in connection with the alternative Big Bang hypothesis.

4. this theory acknowledge that change takes place on a smaller scale. proposes that new stars are continually created at all time at the rate needed to replace the stars wich have used up their fuel and have stopped shining.

5. adhering to the perfect cosmological principle , a principle that asserts that the observable universe is basically the same at any time as at any place. proposed as an alternative to the Big Bang Theory

6. Steady State Theory VS. Big Bang Theory

7. 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. Big Bang Theory most widely cosmological theory of early foundation of the universe. Starts from a single point and form singularity then it expand continuosly.

8. it is expanding, but the distances between matters increasing on very small scale. also expanding and all matter are moving away from each other.

9. Evidences Against the Steady State Theory

10. evidence against the theory began to emerge during the early 1960's: Radio Telescope Observation this observation were saying that there were more cosmic radio sources billion years ago that there are now. This would suggest that the universe is changing over time wich contradicted the theory.

11. 2. Discovery of Quasars bright objects but are very small, only found at great distances from us. Light from them was emitted billions of light years ago. the fact that quasars are only found in the early Universe provides strong evidence that the Universe has change over time.

12. 3. Cosmic Microwave Background this is a weak background radiation wich fills the whole space and is the same in all directions. in the steady Steady State Theory it is almost impossible to explain the origin of this radiation.
