Big Bang Theory

Theoretical Origins of the Universe

  • most widely accepted among scientists at the present

Nobody alive was there

to see this.

• You are under no

obligation to believe this

theory. It is simply one

possible explanation

among many possible

explanations for the

origins of the universe.

Where is Theory found?

 Authored and thought of by several scientists based on work of Hubble’s red shift

Timeline:

  • What we see around us (according to the Big Bang theory) fig. 16-10, pg. 533
  1. Dime sized densely packed piece of matter (containing all the matter in the universe) appeared out of the nothingness and exploded

Timeline:

  1. After ~1million years  the expansion and cooling allowed hydrogen to form
    • now hydrogen is the most abundant element in the known universe

Timeline:

  1. This allowed the formation of other elements, then stars, planets, etc.

Timeline:

  1. Maybe life evolved on other planets in our galaxy or other galaxies as well?

Timeline:

  1. The future of the universe
    • still expanding but for how long?
    • gravity from all existing objects pulls against this expansion
  • 3 possible outcomes
    1. Universe expands forever
    2. Expansion will gradually slow down until a size limit is reached
    3. Expansion will stop and the universe will begin to contract and fall in on itself  Big Crunch

** Depends on the amount of matter in the universe (and the mass)

Problems / Issues /

Flaws with theory:

There was nothing, then there

was something. From where did it come?

 All matter in the universe in a dime sized package

 Outcomes? Which will happen?
