Gnome universe lab: which of the following was NOT a galaxy in our expanding universe lab video

• Sobrero

• M101

• Tadpole

• Milky Way

Gnome Universe Lab: According to the expanding universe lab, what two variables are compared on the Hubble Diagram Graph. 2 answer choices

• Distance to galaxy at time 2

• Recessional speed of galaxy

• Distance to Galaxy at time 1

• time in years

Gnome Universe Lab: What was the slope of the Hubble Diagram Graph called/represent?

• The Hubble Constant

• The age of the universe

• The size of the universe

• Gnomes, definitely Gnomes

Shape of space Video: What is the curvature of the universe like according to the best data we have currently.

• Flat - special case open

• Potato (positive Curve) Closed

• Hyperbolic (negative curve) Open

Shape of space video: What happens to two parallel beams of light in FLAT space

• They stay parallel ==

• The will eventually converge => (come together)

• They will eventually diverge =< (spread apart)

Shape of space video: What happens to two parallel beams of light in Positively curved space. (super potato)

• They stay parallel ==

• The will eventually converge => (come together)

• They will eventually diverge =< (spread apart)

Shape of universe video: What are the TWO ways of measuring the curvature of space?

• Measure triangles in space and see if angle values add up to 180 degrees

• density of matter and energy (average number of hydrogen atoms per cubic centimeter)

• Measure the red shift of nearby stars and galaxies

• Electron Decay Measure the amount of time it will take an electron to decay to smaller subatomic particles.

END OF UNIVERSE VIDEO: Which of the following is NOT a way the universe could end.

• Big Rip

• Big Crunch

• Big Freeze

• Big Bang

END OF UNIVERSE VIDEO: what are the TWO things opposing each other that will determine how the universe ends?

• Gravity

• Dark Energy

• Dark Matter

• The strong Nuclear force
