Gravitational Waves and NASA's Fermi Telescope

What is the primary source of gravitational waves according to astronomers?

• Pulsars

• Exploding supernovas

• Colliding neutron stars

• Orbiting pairs of supermassive black holes

How did Einstein envision the universe in terms of gravitational waves?

• As a flat plane

• As a series of concentric circles

• As a wave pool

• As a static field

What was the first direct detection of gravitational waves attributed to?

• The Laser Interferometer Gravitational-Wave Observatory (LIGO)

• The Fermi Gamma-ray Space Telescope

• The Hubble Space Telescope

• The Chandra X-ray Observatory

What makes detecting gravitational waves challenging?

• They are too fast to capture

• They are drowned out by other cosmic noises

• They are only theoretical

• They are too small to measure

What is the primary advantage of using gamma rays over radio waves in detecting gravitational waves?

• Gamma rays travel faster

• Gamma rays are more abundant

• Gamma rays are easier to detect

• Gamma rays are less affected by interstellar electrons

What is the Fermi Gamma-ray Space Telescope primarily used to study?

• Visible light

• Gamma rays

• Infrared radiation

• Microwaves

What are pulsars?

• Exploding stars

• Supermassive black holes

• Colliding galaxies

• Dense remnants of massive stars

What is the significance of pulsar timing in detecting gravitational waves?

• It helps measure the speed of light

• It reveals the presence of gravitational waves

• It measures the distance to galaxies

• It detects cosmic microwave background

What was the Fermi Telescope named after?

• A famous astronomer

• A type of star

• A space mission

• A Nobel laureate physicist

What is the potential future impact of using the Fermi Telescope in gravitational wave detection?
