Phases of the Universe Quiz

What was the universe primarily composed of immediately after the Big Bang?

• Atoms and molecules

• Electrons, quarks, and other elementary particles

• Stars and galaxies

• Planets and asteroids

During which phase did the universe remain a "superhot fog" that prevented the emission of light?

• Phase 1: Particles

• Phase 2: Superhot fog

• Phase 3: Atom formation

• Phase 4: Galaxy formation era

• Formation of planets

• Creation of black holes

Which particles combined to form the first atoms in the universe?

• Protons, electrons, and neutrons

• Quarks and photons

• Hydrogen and helium

• Stars and gas clouds

What were the first atoms to form in the universe?

• Oxygen and carbon

• Hydrogen and helium

• Iron and nickel

• Lithium and beryllium

What process led to the formation of stars and galaxies?

• Nuclear fusion in atoms

• Clumping of hydrogen and helium atoms due to gravity

• Decay of elementary particles

Which phase marks the beginning of galaxy formation?

• Phase 1: Particles

• Phase 2: Superhot fog

• Phase 3: Atom formation

• Phase 4: Galaxy formation era

How were heavier elements (beyond hydrogen and helium) formed in the universe?

• Through the cooling of the universe

• By the death of the first generation of stars

• By the collision of galaxies

• During the Big Bang itself

What did the heavier elements produced by dying stars contribute to?

• The formation of black holes only

• The creation of new stars and planets
