-
10^-43 s: Space-time is generated. Quarks are formed.
-
You are to create a timeline condensing the 13By history of the universe into 1 calendar year, e.g. 1 January 12am - The Big Bang up to December 31st 12am - present day. MUST include 20 different events.
-
10^-35 - 10^-33 s: Infinitely hot and dense speck of energy begins to inflate. Expansion period ends.
-
10^-33 - 10^-12s: Quarks, electrons, leptons, photons, and neutrinoes are formed
-
10^-10 - 10^-4s: As cooling continues, protons and neutrons are formed from fundamental particles.
-
10^-4s - 3min: Protons and neutrons begin to clump together to form the nuclei of basic elements (H, He, Li).
-
3 hours: The universe has cooled enough for electrons to join with nuclei to form stable atoms.
-
300, 000 years: "Dark Era" ends and Cosmic Microwave Background (CBM) radiation is created.
-
300, 000 years: Particles are drawn together by gravity to form density "bumps", clusters heat up becoming more dense creating a star.
-
400, 000 million years: Over time stars begin to gravitate towards each other to form galaxies.
-
800, 000 million years: Formation of the oldest star in the Milky Way Galaxy, HD 140283.
-
1-4 billion years: Heavier elements have begun to form from old stars.
-
Approx. 1 billion years: Milky Way Galaxy, as we know it today, is formed (No new collisions with other galaxies).
-
5 billion years: The creation of our sun and solar system.
-
9 bllion years: Evolution of our solar system.
-
10.5 billion years: The Earth is formed by accretion from the solar nebula.
-
10 billion years: Earliest signs of life on our planet
-
12 billion years: Earliest evidence of mammals on Earth
-
14.8 billion years: Dinosaurs become extinct
-
14.999 billion years: Homosapiens evolve from previous ancestors.
-
15 billion years: The recent past and life as we know it... Generally boring...
