Objective: I will explore what happened during the first moments after the Big Bang and in the early Universe.
PAGE 19

2. The Big Bang Theory
currently accepted scientific theory regarding the development of the early Universe
scientific estimate:
occurred approximately 13.8 billion years ago

3. The Process Before Big Bang:
entire Universe was contained in a single point (singularity)
Big Bang:
singularity “exploded”
pure energy moved away from singularity faster than the speed of light
energy converted into matter (E=mc2)

4. The Process <1 second after Big Bang: Universe cools
subatomic particles form (protons, neutrons, electrons)

5. The Process Eventually, first atoms formed
Hydrogen, Helium, and Lithium

6. The Process Universe continued to cool and expand
matter clumped together to form first stars and galaxies
