  • 1999 BCE

    Quark and electron created

    Quark and electron are formed because of BigBang
  • 1998 BCE

    hydrogen formed

    3quarks bond themselves and form proton and neutron. 1 proton=hydrogen
  • 1997 BCE

    Helium and hydrogen formed

    2proton=helium
  • 1996 BCE

    neutral atom form

    Because of nuclear formed, it catches electrons
    Hydrogen:Helium=3:1
  • 1995 BCE

    rotating disk formed

    Because of gravity, particles gather together, and they rotate in the same direction.
  • 1994 BCE

    Iron and Nickel core formed

    Because of the sun's formation, there is no more sufficient hydrogen and helium to form. In rotating disk, the small portion part which is Nickel and Iron has become nuclear from nuclear fusion.
  • 1993 BCE

    Atmosphere

    After all nuclear fusion stop because of decreased temperature in the Universe, Atmosphere forms
  • 1992 BCE

    Moon

    moon formed
