The Big Bang Theory

Ali and I have been working on the beginning of the Universe and this is what we have made in class.

Link to the full presentation here.

1) Cosmos: Latin word that comes from Greek, which means organized universe with no chaos.

2) Many interpretations, but the most relevant and believed one through the time: Christian interpretation, which says that God created everything (the Earth, humans, the universe etc.)

3) Hindu interpretation: the world stands on top of some elephants, which stand on a turtle, which are very important symbols in that culture.

4) Time line which represents the development of the cosmos through the time (since the Big Bang happened until now); first three steps (inflation, post-inflation and cosmos cooling) happened in less than 60 seconds.

5) Second time line which shows the universe expanding through the 13,7 billion years that have passed.
 
6) Before the Big Bang: the nothing theory. No matter, no galaxies, no planets, no elements... Absolute nothing.

7) Before the Big Bang: the black hole theory. Before our Universe there was another Universe but it was absorbed by a black hole, and it was so contracted that it had to explode.

8) Third time line in which we can see the matter's development through time: after the Big Bang, protons started moving because of the rise of the temperature forming the very first corps.

9) 300,000 years after Hydrogen and Helium form because particles collide. Then, while the universe was still hot enough, particles fuse and Lithium form.

10) Until now other elements have been forming in 4 types: solid, liquid, gas, and even plasma in the space.

11) 1 billion years after, the gravity effect started affecting Hydrogen and Helium between each other in order to form the first galaxies.
 12) When old stars die, elements heavier than Lithium is sent to the space, which allows new stars and planets to be born in about between 0.5 and 1 billion years.

13) Stars began to die, and their death gave life to other bigger and more complete corps such as planets, asteroids, moons and even other stars.

14) GIF which explains how the universe has been expanding and the corps have been separating between each other through the time.

15) Hubble's law: he confirmed that the universe was expanding. He saw that every single object in space was moving away from the Earth, and the further it is, the faster it moves.

16) Cosmic Microwave Background: the radiation emitted when the Universe stopped being plasma and turned into gas. This happened after 3,000,000 years after because the temperature was so high.

17) Because of the formation of this gas, cloud formed and began to fill
the empty spaces that were in the cosmos.

18)Hartle-Hawking: speculation. The Universe is finite and at one point it will be absorbed by a black hole and explode again.

19) Another theory in the "Eternal Inflation theory", which says that the universe will keep becoming bigger and bigger almost infinitely until another kind of Big Bang happens.

20) What's the truth? Are the theories in which we believe nowadays completely right?

This is a small video we found that summarizes our presentation.


This presentation is a PechaKucha and that's why the information is short and simple.
