- - - - Maguayan & Captan - 2 gods. Their children married each other and had 4 children
    - - Izanami & Izanagi - 2 deities
    - - An egg hatched giving rise to Amen-Ra
      - Nu - primeval ocean
    - - P'an Ku - the first being. Contained in a cosmic egg
    - - Genesis - God created the world in just 6 six days
    - - Other beings emerge after her and from her.
      - Gaia - divine personification of Earth
      - There was only chaos
  - - - Aristotle's Universe
      - Earth-centered
    - - Nicolaus Copernicus' Universe
      - Sun-centered
    - - Sir Isaac Newton's Universe
      - Neither expanding, nor contracting
    - - Edwin Hubble's Universe (1926)
      - Red Shift
    - - Georges Lemaitre's Universe (1920)
      - matter & energy - singularity - pure energy
      - TIMELINE
        
        PLANK ERA
        
        All things are compressed in the singularity
        
        SNF (Protons and Neutrons), EMF (Bet. 2 atoms), WNF (Unstable Atoms), Gravity (Bet. 2 matters)
        
        Temperature: Very Hot
        
        GRAND UNIFICATION
        
        Gravity was separated from the unification
        
        Elementary particles: quarks and electrons
        
        INFLATIONARY EPOCH/ ELECTROWEAK EPOCH
        
        SNF was separated causing the expansion of the singularity.
        
        Followed by EM and WNF
        
        QUARK EPOCH
        
        Quark and anti-quark will annihilate each other returning energy back to space
        
        HADRON EPOCH / LEPTON EPOCH
        
        Quarks combined to from protons and neutrons
        
        Electrons dominated around this time
        
        NUCLEOSYNTHESIS EPOCH
        
        Protons and Neutrons fused to form the nucleus of atoms
        
        RECOMBINATION EPOCH
        
        Nucleus formed elements attracted electrons to be stable and become atoms
        
        DARK ERA
        
        Time bet. atoms and star formation
        
        STAR AND GALAXY FORMATION
        
        First stars were formed. They were massive and short-lived.
        
        SOLAR SYSTEM FORMATION
        
        The earth was formed
        
        PRESENT DAY
        
        Galaxies are still moving away from each other.
      - EVIDENCES
        
        THE EXPANDING UNIVERSE
        
        Edwin Hubble | Red Shift
        
        COSMIC MICROWAVE BACKGROUND
        
        Arno Penzias & Robert Wilson
        
        Signal or radiation = afterglow or the remnants of the big bang theory
        
        COMPOSITION OF THE ELEMENTS
        
        Composition of elements in stars = close to what is predicted
        
        ABUNDANCE OF HYDROGEN
