Quiz #3 The Big Bang, Life of Stars and Electromagnetic Waves

A large grouping of stars, planets, gas, and dust in space held together by gravity.

• Universe

• Galaxy

• Space

Answer explanation

A galaxy is a large grouping of stars, planets, gas, and dust held together by gravity. The universe encompasses everything, while space refers to the vast expanse between celestial bodies. Thus, the correct answer is galaxy.

All space and the matter space contains

• Universe

• Galaxy

• Super Nova

Answer explanation

The correct answer is 'Universe' because it encompasses all space and matter, including galaxies and supernovae, making it the broadest term that includes everything in existence.

Which description is considered most accurate regarding what actually happened during the Big Bang?

• Two galaxies collided causing an immense explosion as stars crashed into one another

• All of what would become the universe was concentrated in a single small point, or singularity, which rapidly expanded into what is now stars, planets, galaxies, matter, and energy.

• All matter emerged from a massive black hole at the center of the universe.

• Parts of the sun were ripped off by massive internal explosions and were thrown into space where they cooled to become other things, like plants, comets, and other galaxies.

Answer explanation

The correct choice describes the Big Bang as the rapid expansion of a singularity, which is the widely accepted scientific explanation for the origin of the universe, leading to the formation of all matter and energy.

Which of the following is evidence of the Big Bang Theory?

• Cavemen heard a loud bang at the beginning of time.

• The universe isn't moving

• The universe is expanding

• The universe is getting smaller

Answer explanation

The universe is expanding is evidence of the Big Bang Theory, as it suggests that the universe started from a singular point and has been growing ever since, supporting the idea of an initial explosive event.

The universe is expanding.  This means that:

• Galaxies are getting bigger.

• Atoms are getting bigger.

• The universe is creating more matter.

• The amount of space between galaxies is increasing.

Answer explanation

The universe's expansion refers to the increasing distance between galaxies, not their size or the creation of more matter. Thus, the correct choice is that the amount of space between galaxies is increasing.

A system of objects that revolve around a star

• Big Bang

• Solar System

• Light Year

• Galaxy

Answer explanation

The correct answer is 'Solar System' because it specifically refers to a system of objects, including planets and moons, that revolve around a star, which in our case is the Sun.

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.

Answer explanation

The correct answer is 'There is no center of the universe.' This is because the universe is expanding uniformly, and every point can be considered as the center from its own perspective.

What does the Big Bang theory suggest?

• The universe was just there

• The Milky Way is the only solar system

• The universe is continually expanding

• The universe is collapsing in toward a single point

Answer explanation

The Big Bang theory posits that the universe began from a singular point and has been expanding ever since. This means the correct choice is that the universe is continually expanding, not collapsing or just existing.

What were the original two elements in our universe?

• Lithium and Carbon

• Hydrogen and Neon

• Helium and Chlorine

• Hydrogen and Helium

Answer explanation

The original two elements in our universe are Hydrogen and Helium. They were formed during the Big Bang nucleosynthesis, making them the most abundant elements in the universe.

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

• Abundance of Hydrogen and Helium

• CMBR everywhere

• Stars that are blue shifted

• the universe is getting bigger

Answer explanation

Stars that are blue shifted indicate they are moving towards us, which is not evidence of the Big Bang. In contrast, the other options support the theory by showing the universe's expansion and the presence of primordial elements.
