Which of the following statements is NOT true about neutron stars?
  a. They resist collapse with a pressure that stems from the Pauli exclusion principle.
  b. If the mass of the neutron star is more than 3 solar masses, it can continue to collapse and become a black hole.
  c. Some of the neutrons inside were formed from an electron-proton interaction.
  d. Neutron stars are believed to be the explanation for pulsars.
  e. The formation of neutron stars is a process known to absorb neutrinos.

Question 2

Joseph Weber is best known for

  c. Observing gravitational waves indirectly through the discovery of a binary system that includes a pulsar.
  d. Originated the LIGO project.

Answer to Question 1

e.
This statement is not true. Neutron stars are not necessarily known to absorb neutrinos, the light, non-charged particles produced in some nuclear reactions. Instead, they are known to emit neutrinos as electrons and protons fuse to form neutrons and an electron neutrino.

Answer to Question 2

a. Weber first claimed to detect gravitational waves in 1968, but his experiment was not confirmed.
