Multiple Choice

Section: Introduction

What does Genesis 1 state about the creation of the earth and other celestial bodies?

• The creation order is not specified.

• The sun was created first, followed by the earth and then other stars.

• The earth was created before the sun, moon, and stars.

• The earth and other celestial bodies were created simultaneously.

Multiple Choice

Section: Introduction

Who is credited with the origin of the modern theory of solar system formation?

• Isaac Newton

• Albert Einstein

• Stephen Hawking

• Emmanuel Swedenborg

Multiple Choice

Section: Introduction

What was the nebular hypothesis about?

• The solar system was created in six days.

• The solar system began as a contracting and cooling proto-solar nebula.

• The solar system formed from a black hole.

• The solar system formed from a giant explosion.

Multiple Choice

Section: Introduction

Why was the nebular hypothesis eventually abandoned?

• It was proven wrong by the discovery of black holes.

• Due to lack of observational evidence.

• It contradicted the theory of relativity.

• Because of the angular momentum problem.

Multiple Choice

Section: Introduction

What did the tidal hypothesis suggest?

• Tidal forces from black holes shaped the solar system.

• The moon's gravity caused the formation of the solar system.

• A passing star raised tidal bulges on the sun, leading to planet formation.

• The solar system formed from tidal waves in the primordial universe.

Multiple Choice

Section: Nebula Once "Proof" for Evolutionary Views of Universe

What discovery did Edwin Hubble make in 1924?

• The cosmic microwave background radiation.

• The existence of dark matter.

• Spiral nebulae are actually distant galaxies.

• The universe is expanding.

Multiple Choice

Section: Revival of Old Nebular Hypothesis

What is a planetesimal according to the modern theory?

• A large gas giant in the early stages of formation.

• A miniature black hole.

• A comet passing through the solar system.

• A small body that grows by attracting more material.

Multiple Choice

Section: Revival of Old Nebular Hypothesis

Modern theories of solar system formation propose that the energy from a supernova (exploding star) can condense a gas cloud to begin forming a star/solar system.

What problem to the modern theory of solar system formation does this cause?

• The issue of from where did the exploding star (supernova) originate.

• The issue of dark energy.

• The formation of black holes.

• The existence of exoplanets.

Multiple Choice

Section: Modern Theory of Solar System Formation

How do astronomers today attempt to observe solar system formation?

• Using time travel technology.

• By observing objects in various stages of formation.

• Through direct observation of planet formation.

• By creating miniature solar systems in the lab.

Multiple Choice

Section: Star Formation Today?

According to current theories of planet formation, gas giant planets should be far away from the star that they orbit. What have astronomers so far observed.

• Our solar system's gas giants are far from the sun but other solar systems have gas giants very close to their star.

• Both our solar system and other solar systems have gas giants far from their sun/star.

• Our solar system's gas giants are close to the sun but other solar systems have gas giants far from their star.

• Both our solar system and other solar systems have gas giants close to their sun/star.
