What is the difference between a theory and a law?
A theory explains what happens and a law explains why
A theory can be changed, while a law is usually proven mathematically
What is the universe?

Expanding
Contracting
Heating up
Reorder the following, 1 being the start of the big bang
Singularity explodes
Gas like H and He are created
Gases in space cooled
Gravity causes stars, planets, and galaxies to be created
the leftovers from the big bang that are in the form of microwave radiation is known as
Mixture of elements
Doppler Effect
Cosmic Background Radiation
Red Shift
Each (a) has a specific spectrum, or fingerprint, that helps us identify what a galaxy or star is composed of.

Which of the following IS NOT true about Hubbles Law?
The Universe is Expanding
Galaxies are all moving away at Equal Rates
Galaxies are Accellerating away from us depending on there distance from us
Most of the Galaxies in the Universe are moving away from us
What is the big crunch theory
The big crunch theory is the expanding and condensing of the universe in a reoccurring pattern.
The big crunch theory is that the universe will expand infinitely and all atoms will seperate from each other.
What is the big rip theory
The big rip theory is when the universe cools to zero and all objects reach a fixed position
The big rip theory posits that the universe will eventually stop expanding and collapse back in on itself.
The big rip theory is the expanding and condensing of the universe in a reoccurring pattern.
The big rip theory is that the universe will expand infinitely and all atoms will separate from each other then explode.
What is the big freeze theory
The big freeze theory is when the universe cools to zero and all objects reach a fixed position
The big freeze theory posits that the universe will eventually stop expanding and collapse back in on itself.
The big freeze theory is the expanding and condensing of the universe in a reoccurring pattern.
The big freeze theory is that the universe will expand infinitely and all atoms will separate from each other then explode.
What is the big bounce theory
The big bounce theory is when the universe cools to zero and all objects reach a fixed position
The big bounce theory posits that the universe will eventually contract back into a singularity and another big bang will occur
The big bounce theory is the expanding and condensing of the universe in a reoccurring pattern.
The big bounce theory is that the universe will expand infinitely and all atoms will separate from each other then explode.
In the process of nuclear fusion, hydrogen atoms combine to form ___________ atoms.
helium
carbon
nitrogen
oxygen

Singularity
Antimatter
Little bang
condensation nuclei
A perfect blackbody spectrum was detected by what telescope?
COBE Telescope
How did the discovery of cosmic microwave background radiation support the Big Bang theory?
It provided evidence for the prediction that the universe began as a hot, dense state and has been expanding and cooling ever since.
It showed that the universe is much younger than previously thought
It confirmed the theory that the universe is static and unchanging
It disproved the idea that the universe is constantly expanding
