Big Bang Timeline

  • The Big Bang

    The Big Bang
    Quark Net A cataclysmic event that was a reult of a large explosion from an infinitely dense ball at 12: 00 am. Fractions of seconds later as it expands it becomes less dense and cools, and basic forms of forces come about such as gravity that will apply in the formation of atoms and sub-atomic particles.
  • Radiation era

    Radiation era
    The Radiation Era The first major era that started 10 000 years after the Big Bang somewhere near 12: 01 am, in which most of the energy in the universe is in the form of radiation - radio waves, UV rays and X Rays in a process called nucleosynthesis. As the universe expands these waves are strectched and diluted into faint microwaves. This period would continue for 300 000 years up into the matter dominated era.
  • Era of Matter Domination

    Era of Matter Domination
    Matter Dominated Era This era began at the end of the radiation era with the energy in matter and radiation equalling. Neutral atoms are formed by electrons link up with hydrogen and helium nuclei, and leaves microwave radiation in the background. It was said to be the epoch of the evolution of the universe when it was 300
    000 years old at aprroximately 12: 11 am.

    Big Bang Timeline

  • First Galaxy Formation

    First Galaxy Formation
    Galaxy As slight gravitational irregularities emerged in nebulae, dense gas pockets came about and continued becoming more and more denser, stars would ignite and form as protostars which subsequently formed the earliest glaxies at 12: 00 am.
  • Birth of the Sun

    Birth of the Sun
    The Birth of the Sun The Sun was born out of the remnants of a supernova of a previous star at 10: 10 am. The Sun first formed as a Protostar, but as the custer of hot dense gases begin to compress and rotate continuously gradually the temperature would reach 10 million degrees kelvin. When that time comes, nuclear fusion begins and the Sun is born into a yellow dwarve star.
  • Birth of the Solar System

    Birth of the Solar System
    formation of the Solar System As the sun was in the phase of protostar, the rotation of the star caused an orbit on the surrounding gases and dust. Gradually after time these gases and dust will clump together into small rocks, then after time, large celestial bodies known as planets at 3: 19 am.
  • First Life Forms

    First Life Forms
    First lifeforms The first life forms were neither fauna or flora as the atmosphere was still toxic at this time. Due to the Earth cooling, the toxic atmosphere of nitro gas, carbon dioxide and water vapour, it began to precipitate, forming the ancient oceans of the world. In these oceans life forms came about as small bacteria about 700 million years ago at 5: 00 pm.
  • Primitive Life Forms

    Primitive Life Forms
    Primitive life Small life forms came about, mostly as flatworms, jellyfish, algae and bonless beings from elvoving from bacterial beings 700 million years ago at 5: 00 pm.
  • First Mammals Appear

    First Mammals Appear
    First mammals The first mammals evolved from a class of reptiles with mammal-like traits. many of these mammals were small rodents such as rats that would remain burrowed underground 200 million years ago at 8: am.
  • The Extinction of Dinosaurs

    The Extinction of Dinosaurs
    Death of the Dinosaurs The era of the dinosaurs ended as a result of a cataclysmic event that would wipe out almost all life on Earth at. What really caused the extinction is unknown but many theories circulated in as possible events such as an asteroid. Only few reptiles would survive while many mammals, fish and birds would live on.
  • Supernova 1987A Explodes

    1987A SupernovaCrab supernovaCrab nova
    A blue supergiant star, 25 times the size of our sun, explodes in a firery nuclear reaction known as a supernova and distributes elements such as oxygen, carbon, nitrogen and iron into space 170 000 years ago at 11 pm. The nova to place in a dwarf nebula outside of the Milky Way known as the Large Magellanic Cloud.
  • Crab Supernova Appears

    Crab Supernova Appears
    Crab Supernova Recorded by Japanese, Chineses and Native Americans in 1054 A.D. (midnight) a star in the new constelation of Taurus outshined Venus in the Night sky. The remains of the star can still be seen today and scientist have discovered a pulsar within the remnants of the Crab Nebula.
  • Big Bang Confirmed

    Big Bang Confirmed
    Big Bang Confirmed The Big Bang theory had been confirmed by Astronomers in 1990 (midnight) with use of the Cosmic Background Explorer Satellite and discover that the radiation is in near perfect agreement with the Big Bang theory.
  • Background Radiation Discovered

    Background Radiation Discovered
    Discovery of Background Radiation In 1964 (Midnight) , scientists dicovered a microwaved background radiation in the universe and found it to be the reminents of the Big Bang. The background radiation was measured to be only 3 K upon its discovery and would be a map on how the universe was shaped and the path of matter in the early universe.
