Universe

If you were given a chance to create your own world or universe, how would it look like?

The Universe

Many people believe that nature, the sun and moon, the stars, even human beings never had a beginning. There is a endless, external cycle of birth, life, and death that constantly repeats itself. This external cycle never began and will never end. It always has been and will always be.

The Universe

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. All the planets, stars, and galaxies are part of the universe, and so, is all of space.Cosmology is the study of universe.

Theories on the Origin of the Universe

1. Big Bang TheoryMost 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)

Theories on the Origin of the Universe

2. Open UniverseEdwin 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.

Theories on the Origin of the Universe

3. Steady StateProposed 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.
