Do we know exactly what happened the first 300,000 years ago?

• Yes, we were able to capture the moment

• No, we only could use the knowledge of subatomic particles and computer models to predict the event

Which statement below is INCORRECT about star formation during the beginning of the Universe?

• Stars formed at a rate of 10 times HIGHER than present-day Universe

• The gas eventually became hot and dense for stars to be born

• Large clusters of cloud began to form the first galaxies

• Stars formed at a rate of 10 times SLOWER than present-day Universe

What allowed the formation of stars?

• The dense areas pulled in material because of gravity

• The Universe was filled with clouds of hydrogen and helium gas

• The gas eventually became hot and dense

• All of the above

Place in order the sequence of how our universe formed after the initial appearance:

• (1) gravity pulling in materials, (2) formation of atoms, (3) formation of stars from hot & dense gas, (4) clusters of stars forming into galaxies, (5) cooling, (6) expansion

• (1) cooling, (2) expansion, (3) formation of atoms, (4) formation of stars from hot & dense gas, (5) gravity pulling materials, (6) clusters of stars forming into galaxies

• (1) expansion, (2) cooling, (3) formation of atoms, (4) gravity pulling in materials, (5) formation of stars from hot & dense gas, (6) clusters of stars forming into galaxies

• (1) gravity pulling in materials, (2) formation of atoms, (3) formation of stars from hot & dense gas, (4) clusters of stars forming into galaxies, (5) expansion, (6) cooling

Where is the center of the universe located?

• There is no center of the universe.

• At the center of the Milky Way galaxy.

• 14.5 billion light years away from Earth.

• In a large singularity near the Andromeda Galaxy.

The "afterglow" of the energy from the origin of the universe that we see today.

• Cosmic microwave radiation

• sunlight

• Doppler effect

• Cosmic explosions
