Big Bang

How many main stages did occur?

4 main stages

What is the 'Big Bang Theory'?

A rapid explosion of matter from a state of extremely high density and temperature.

What was the second main stage of the 'Big Bang'?

All of the energy and heat from the explosion shot out. Where ever it travelled it created space. All of the particles formed everything we see today, stars planets etc.

Who discovered the 'Big Bang Theory'?

Edwin Hubble

What was the fourth main stage of the 'Big Bang'?

Everything started to settle and the universe we recognize today started to form. As the particles began to cool down and spread out, the electrons, neutrons and protons began to come together and create atoms. These atoms then eventually combined to create mass. creating stars, planets, galaxies and everything else in the universe.

What was the third main stage of the 'Big Bang'?

The universe became super heated. The heat was so high that particles from the Big Bang couldn't form mass or atoms. Because of this, neutrons, protons and electrons started to join. light photons were continuously bouncing off or latching onto electrons which caused a constant glow coming from the universe.

True of False: Matter that we cannot see is called 'Dark Matter'?

True

What was the first stage main of the 'Big Bang'?

'The tiny dot': Before the 'Big Bang' the universe did not exist. Everything in the universe was squished into one tiny dot. It then exploded.

What evidence have scientists used to prove the 'big Bang Theory'?

-Cosmic background radiation -Universe expansion -Red shift.
