Which of the following is NOT true about the Big Bang Theory?

• It is the scientific explanation of how life began on Earth and evolved over time.

• It is the scientific explanation for the origin of the universe.

• It states that the universe expanded from a single point and is still expanding today.

• It states that the universe used to be much hotter and smaller.

What is the Cosmic Microwave Background?

• The shape of the universe

• The first primordial elements

• Red shifted galaxies

• Leftover heat from the Big Bang

Which of the following is NOT evidence of the Big Bang Theory?

• Abundance of Hydrogen and Helium

• CMB everywhere

• Stars that are blue shifted

• the universe is getting bigger

Which of the following is the best description of the Big Bang Theory?

• The Big Bang Theory is the prevailing model about the universe’s origin and is supported by observations of the universe’s expansion.
• The Big Bang Theory is just one of the ideas about the universe’s origin, many of which are equally respected by the scientific community.
• The Big Bang Theory states that pre-existing matter was compacted into a hot and dense form and suddenly exploded into infinite, empty space.
• The Big Bang Theory is the scientific explanation of how the Sun, Earth, and the rest of the Solar System were formed at the beginning of time.

As part of the modern theory of the origins of the elements, it is hypothesized that before the formation of the stars, most of the matter in the universe consisted of what atoms?

• hydrogen and helium
• nitrogen and carbon
• silicon and lithium
• uranium and radium

Why do red-shifted light spectrums from neighboring galaxies  indicate the universe is expanding?

• Red light has the shortest wavelength on the visible light spectrum
• Red light has the longest wavelength on the visible light spectrum
• Red light has both long and short wavelengths on the visible light spectrum
• Red light has neither long, not short wavelengths on the visible light spectrum

Why is the abundance of H/He throughout galaxies an important piece of evidence supporting the Big Bang?

• H/He were two of the first elements to form following the Big Bang.
• H/He are highly reactive generating hot spots.
• H/He are high mass elements formed from supernovae.
• All the above

What forms in the very center of the Protostellar disk?

• A sun

• A planet

• A protoplanet

• A planetesimal

During the formation of our solar system, while the sun is forming and taking shape what is also forming away from the center?

• Light

• Protostars

• Planetesimals

• Hydrogen

The planetesimals keep:

• Colliding and breaking apart
• Colliding and sticking together
• Colliding and bouncing around
• Breaking down into smaller pieces
