The Big Bang Timeline
-
The Big Bang - 10^-43
The first small specs of of space and time come into existance. The universe is infinitely hot and dencs at this point. -
The Big Bang 10^35s - 10^33s
Universe expanded hugely to the size of a grape fruit. The Inflation caused the energy to form into subatomic particle like quarks and leptons. -
The Big Bang - 10^-6
The universe startes to take shape. The universe grows in siza and still has the same amount of mattere. It also becomase less dence therefore less hotter because of the size. The Fundamental Forces are produced. -
The Big Bang - 1s
After one second, protons and neutrons start to form from quarks. -
The Big Bang - 3s
Helium necleus started to form with out any electrons because the electrons are still moving around to fast because of the heat. Also Hydrogen and Lithium necleus were formed. -
The Big Bang - 300,000 years
Stable atoms can be produced. Electrons are now cool enought to start orbiting and the necleuses. -
The Big Bang - 300M Years
Gravity Pulls matter together and forms large clouds of gass. Stars are produced from the gas. These stars gravitate together to form galaxies. -
Big Bang - 700 Million year
First visible galaxies -
Big Bang - 12 Billion years ago
The Milky Way was formed -
Big Bang - 4.65 Billion years ago
Solar System Formed. Sun formed -
Big Bang - 4.5 Billion years ago
Earth's structure started forming -

Earliest Life -
Big Bang - 700 Million years ago
Primitive Animals Appear. These are mostly flatworms, jelly fish and algae. -

The Big Bang - 200 Million Years ago
The Extintion of dinosaurs -
Big Bang - 600,00 years ago
Homo Sapiens Evolve. Our earliest ancestors evolve in Africa from a line of creatures that descended from apes. -
Big Bang - 200,000 years ago
