Understanding the Universe's Expansion

What is the primary purpose of the Hubble Space Telescope in relation to the universe's expansion?

• To measure the expansion rate of the universe

• To observe the surface of planets

• To measure the distance to nearby stars

• To detect black holes

How does dark energy affect the universe's expansion?

• It accelerates the expansion

• It has no effect on the expansion

• It slows down the expansion

• It reverses the expansion

Which theory explains the concept of repulsive gravity caused by dark energy?

• String theory

• Einstein's theory of general relativity

• Quantum mechanics

• Newton's theory of gravity

What advantage does the James Webb Space Telescope have over the Hubble Space Telescope?

• It is closer to Earth

• It has a larger field of view

• It can observe in the ultraviolet spectrum

• It has greater resolution and can observe further into the infrared spectrum

What is the ultimate goal of using both the Hubble and James Webb Space Telescopes?

• To discover new galaxies

• To map the Milky Way galaxy

• To measure the Hubble constant with one percent precision

• To find new planets
