Gravitational Waves and Neutron Star Collisions

What was the first cosmic event detected by LIGO in 2015?

• A gamma-ray burst

• A neutron star merger

• A black hole merger

• A supernova explosion

What was unique about the 2019 neutron star collision detection?

• It was accompanied by a flash of light

• It was detected by only one LIGO site

• It was the first detection of gravitational waves

• It was detected by both LIGO sites

What was the combined mass of the neutron stars in the 2019 event compared to our Sun?

• 1.4 times the mass of the Sun

• 2.4 times the mass of the Sun

• 3.4 times the mass of the Sun

• 4.4 times the mass of the Sun

What do neutron star collisions help produce?

• Dark matter

• Heavy elements like gold and platinum

• Cosmic rays
