Hypothesis
• What is it?• A hypothesis is a guess as to why something
happens. • How does it happen?• Observations lead to questions regarding the event. • Example: Why is the sky blue? How does gravity
affect falling objects?• In attempting to answer a question about the nature
of the world, a scientist will form a hypothesis (or a guess) regarding the question's answer.

Definition
• Hypothesis: A creative idea as to how a scientific event or entity came to be, based on a number of logical assumptions.
• There is no scientific basis for a hypothesis, but the idea comes from logical assumptions.
• Once enough data supports the hypothesis it becomes a:

Theory
![Page 5: Theory vs. Hypothesis Hypothesis What is it? A hypothesis is a guess as to why something happens. How does it happen? Observations lead to questions.](https://reader031.fdocuments.net/reader031/viewer/2022013101/56649f4a5503460f94c6c3db/html5/thumbnails/5.jpg)
Definition
• Theory: an idea that results when a hypothesis is supported by observation and scientific inquiry.

The Big Bang
• A widely held scientific theory that contends the creation of the universe, the Milky Way, and our solar system resulted from a violent explosion of matter.

How the theory goes!
1. The cosmo goes through a super fast inflation. Expanding from the size of an atom to the size of a grapefruit in a tiny fraction of a second.

Post-inflation
2. The universe is a seething hot soup of electrons quarks and other particles.
• Quarks-multidimensional elements that are nothing but energy.

Cooling
3. A rapidly cooling cosmos permits quarks to clump into protons and neutrons

Super hot
4. Still too hot to form into atoms, charged electrons and protons prevent light from shining; the universe is a super hot fog.

Light
5. Electrons combine with protons and neutrons to form atoms, mostly hydrogen and helium. Light can finally shine.

Gravity
6. Gravity makes hydrogen and helium gas coalesce to form the giant clouds to form galaxies; smaller clumps of gas collapse to form the first stars.
• Coalesce: to unite or bond into one

New stars and planets
7. As galaxies cluster together under gravity the first stars die and spew heavy elements into space; these will eventually form into new stars and planets.
