Origins of the universe1
Origins of the Universe

  • Three options are possible

  • Option 1- Someone made the Universe

    • Creationist theory- God made it

    • Big Bang Theory

  • Option 2- The Universe made itself

  • Option 3- The Universe has always been there

    Steady State Theory

  • Big bang theory
    Big Bang Theory

    • Happened approximately 15 billion years ago

      • 13.7 billion years ago

  • Scientist believe our universe started as a hot, dense compressed mass a few millimeters across

    • The size of a pin head

  • This lasted for only a fraction of a second

  • Then there was a huge blast, explosion, or event causing the universe to expand at an incredible rate

  • Then we had the production of protons, neutrons, and electrons which lead to gases that could form primitive galaxies

  • The big bang theory
    The Big Bang theory

    • Scientist credited- Georges Lemaitre in 1927

    • Fred Hoyle coined the term “Big Bang “ in 1949

    • Support came from Einstein’s theory of relativity

    • Also from Edwin Hubble in the 1920’s- he showed that stars were moving away faster than anticipated so it must be due to the expansion of the universe

    • Still believed today- current scientific theory

    Problems with the theory
    Problems with the theory

    • Does not presume to talk about the initial creation of the universe

    • Only attempts to explain the expansion from a hot dense particle

    Creationist theory
    Creationist Theory

    • Who: God/Jesus

    • Time Frame- The writing of the Bible

    • Evidence-Chapters 1 and 2 of Genesis

    • Basic Principles- God created the universe in 7 days and determined “everything was good.” This is not meant to be a literal interpretation but a metamorphic for perfection.

    • Geologic landforms and sedimentary features are completely consistent with a worldwide flood as described in the Book of Genesis.

    • Enormous limestone formations, huge coal and oil formations, and immense underground salt layers are indicative of a worldwide flood—not slow and gradual processes over billions of years. Such features are satisfactorily explained by a worldwide flood and known geophysical and geochemical processes.

    • A worldwide flood as described in Genesis 6–8 is within the boundaries of known geophysics—see phase diagram in chapter 4 and Pangaea Flood Video at


    Steady state theory
    Steady State Theory

    • First proposed by Sir James Jean in 1920

    • 1948- Fred Hoyle, Thomas Gold, and Hermann Bondi

    • Discredited theory- not believed today (1960’s)

    • Basic Principles- The universe is expanding but it does not change its appearance over time.

    • The universe looks essentially the same from every point in it and at every time.

    Steady state continued
    Steady State continued

    • It was proposed as another mathematical explanation for the origin of the universe

    • Scientific Evidence against:

    • 1960- quasars- the luminous cores of distant galaxies

    • Also Arno Penzias and Robert Wilson discovered cosmic microwave radiation left over from the Big Bang.

    Oscillating universe model
    Oscillating Universe Model

    • Proposed partially by Einstein in the 1930’s and Richard Tolman- 1934 ( Tolman more to discredit)

    • Also proposed an alternative to the Creationist theory (more for the Hindu and Buddha dominated religions that believe in reincarnation)

    • Basic principle- It is a combination of the Big Bang theory followed by a Big Crunch.

    • If the universe expands then it will get to a point of maximum expansion. If this happens then a Big Crunch will happen ( the universe will collapse) only to Bounce Back

    Oscillating Model cont.

    • Has certain philosophical merit

    • Little scientific evidence for it. Mostly to discredit the theory.

    • If it were to happen this way then the end is more likely an end- we would go into a black hole and never return

    • Also- the cosmic microwave radiation

    • Tolman says this goes against the Second Law of Thermodynamics
