SIZE AND STRUCTURE OF THE UNIVERSE

The Universe is so big that we could imagine. The matter of the Universe is concentrated in only a small part of it.

The visible universe's size: 
 -The universe's limits, from the earth, are at 46.500 ligth-year millions to all directions.
 -After the Big Bang, the universe fastly expand and a half of his light didn't arrive to us and, thats why we can see it.

 Structure:
 The matter in the universe forms:
 -Minor structures (stars and system).
 -Galaxies are medium size structures formed by gas, dust and dark matter.
 -A common form is the elliptical galaxy
 -Spiral Galaxies are disk-shaped with dusty, curving arms, like the Milky Way.
-Irregular galaxies are irregular or unusual shapes.

 

Cumuls of galaxies: 
They are a set of galaxies wrapped up in warm gas. The galaxies turn one each other join by the gravity power. Sometimes they hit or absorb thereselves.

Supercumuls of galaxies: 
They are sets of galaxies, formed by big caps from all the universe. The local group are formed by the supercumul of Virgo.

Wall:
Those are the last discovered structures and the oldest and biggest in the universe. The form big strips of supercumuls of galaxies.

The Big Atractor:
The supercumul of Virgo and the other structures of the universe reach to a mistery point called The Big Atractor.

Summary: Big Bang and the Universe

The Big Bang

It's a theory about the origin of the Universe

 - It started from a dense atom that exploded.
 - It increased 90 times its size, very fast.
 - Nowadays, It is still expanding, but at a slower rate.
 - At first, it was a dark place because atoms weren't formed.
 - Recombination: next, atoms were formed and  the Universe became transparent.
 - Finally, galaxies and stars were created.


The origin of the Solar System

 - It was born 9 billion years after The Big Bang.
 - Its age is about 4.6 billion years.
 - The Sun and the Solar System were formed from a cloud of gas called Solar Nebula
 - This nebula collapsed, it spun faster and flattened into a disk.
 - Most of the material was concentrated in the centre and the Sun was formed.
 - The rest formed planets, satellites, comets, etc...

Dark Matter

 - Mysterious and invisible mass formed by exotic particles that don't interact with light or regular matter.
 - It is inferred because of the gravitational pull.
 - It is the 23% of the Universe , with 4% being regular matter.


Dark Energy

  - Strange, pulling and expansive force that remains undetected and makes 73% of the Universe.
