The Universe Review # 3

What is the steady state theory and what do these theorists believe?

• The steady state theory is an idea about the formation of our universe. These theorists believe the universe has always existed and has no start or end. 

• The steady state theory is an idea about Earth’s formation. These theorists believe the Earth came from the Sun

• The steady state theory is an idea about Earth’s formation. These theorists believe the Earth came from nowhere

• The steady state theory is an idea about the formation of our universe. These theorists believe the universe began with a big explosion

Which of the following is considered correct evidence for the Big Bang Theory?

• The composition and density of the universe is constantly changing as the universe expands

• The composition and density of the universe always stays the same as the universe expands.

• The composition and density of the universe always stays the same as the universe gets smaller

• The composition and density of the universe is constantly changing as the universe gets smaller

How did Kepler’s discovery change the view of the universe?

• Scientists previously believed the planets orbited the Sun in circular paths, but Kepler discovered the planets actually orbit the sun in elliptical paths

• Scientists previously believed the planets orbited the Sun in elliptical paths, but Kepler discovered the planets actually orbit the Sun in circular paths

Which of the following was one of the discoveries Galileo made with his telescope?

• The orbit of each planet is an ellipse.

• One side of the Moon always faces Earth

• 
  Most of the smaller planets are closer to the Sun.

• Venus goes through phases similar to those of Earth's Moon. 

How did Newton’s work with gravitational pull help support the heliocentric model of the universe?

• Newton discovered the less mass an object contains the greater its gravitational pull will be therefore all planets must orbit the Sun

• 
  Newton discovered the less mass an object contains the greater its gravitational pull will be therefore all planets must orbit the Earth.

• Newton discovered the more mass an object contains the greater its gravitational pull will be therefore all planets must orbit the Sun.

• Newton discovered the more mass an object contains the greater its gravitational pull will be therefore all planets must orbit the Earth.
