ELS Quiz 1: Lesson 1 and 2

Which theory suggests that the universe began as a singularity and expanded rapidly in a hot and dense state?

• The Big Bang Theory

• The Steady State Theory

• The Oscillating Universe Theory

• The Multiverse Theory

According to the Big Bang Theory, how long has the universe been expanding for?

• 13.8 billion years

• 10 billion years

• 5 billion years

• 20 billion years

Which theory posits that the universe has no beginning and no end, and that new matter is continuously created?

• The Multiverse Theory

• The Big Bang Theory

• The Oscillating Universe Theory

• The Steady State Theory

The Multiverse Theory suggests that our universe is just one of many, each with its own physical properties. What are the other theories mentioned in relation to this?

• The Big Bang and steady-state

• The Oscillating Universe and Eternal Inflation

• The Nebular and Capture Hypothesis

• The Steady State and Tidal Hypothesis

Which theory suggests that the universe undergoes an infinite series of cycles, with each cycle beginning with a Big Bang and ending in a Big Crunch?

• The Multiverse Theory

• The Oscillating Universe Theory

• The Steady State Theory

• The Big Bang Theory

According to Laplace, what happened that made the slowly rotating cloud of incandescent gases start to collapse in on itself?

• A supernova explosion

• A collision with another galaxy

• A disturbance in the force

• Gravity

Which hypothesis suggests that some planets and other objects in the solar system might have been formed elsewhere in space and were then captured by the Sun's gravitational pull?

• Nebular Hypothesis

• Tidal Hypothesis

• Planetesimal Hypothesis

• Capture Hypothesis

What is a variation of the Nebular Hypothesis that emphasizes the role of planetesimals?

• Capture Hypothesis

• Tidal Hypothesis

• Steady State Theory

• Planetesimal Hypothesis

Which hypothesis proposes that a near collision between the Sun and another star could have disturbed a pre-existing cloud of gas and dust, causing material to be pulled out and form planets?

• Capture Hypothesis

• Steady State Theory

• Planetesimal Hypothesis

• Tidal Hypothesis

The Tidal Hypothesis suggests that a near collision between the Sun and another star could have disturbed a pre-existing cloud of gas and dust, causing material to be pulled out and form planets. What is the other hypothesis mentioned in relation to this?

• Steady State Theory

• Planetesimal Hypothesis

• Capture Hypothesis

• Nebular Hypothesis
