Theories explaining the origin of the universe.
The document discusses theories on the origin of the universe. It describes the Big Bang Theory, which proposes that the universe began approximately 15 billion years ago from a huge explosion. It also describes the Open Universe theory, where galaxies are continually moving farther apart and may eventually collide in a "Big Crunch." Additionally, it outlines the Steady State theory, which suggests the universe has neither a beginning nor end and matter is constantly created throughout the universe.

- 4. In the Bible,there was time when the world did not exist. Only God existed. He decided to create the world and with that decision, the world began. the universe is everything that exists.

- 5. Theories on theOrigin of the Universe 1. Big Bang Theory Most astronomers believe that the universe began about 15 billion years ago, in a huge explosion they called the Big Bang. This theory successfully explains the expansion of the universe and the observed abundance of helium in the universe. • First developed in 1927 by Georges Lemaitre (1984-1966) • and coined and revised by George Gamow (1904-1968)

- 11. Theories on theOrigin of the Universe 2. Open Universe Edwin Hubble (1889-1953) discovered the galaxies of the universe are moving farther apart. This means that the universe is getting continually bigger or getting bigger forever. Alternatively, the galaxies may come together, until finally they will collide and explode. This event is called the “Big Crunch”. If the Big Crunch occurred, the sky would grow as hot as the sun. Finally, everything would vanish into a blackhole.
- 16. Theories on theOrigin of the Universe 3. Steady State Proposed by Hermann Bondi, Thomas Gold, and Fred Hoyle in 1928, this suggests that there is neither beginning nor end to the universe, and it has a constant mean density. This theory postulates that matter is created throughout the universe at a rate of about 10-10 nucleon per meter cube per year as a property of space. this violates the Law of Conservation of Matter and Energy.
