The Quest for Black Holes every pulsar is a neutron star, but not every neutron star is a pulsar neutron stars have very strong magnetic field can only see pulsars when the radio waves are facing towards us o because of the fast rotation Neutron stars are so dense and have such a great gravitational field that Newton’s laws do not apply o have to use Einstein’s theory of relativity General theory of Relativity o matter and energy warp space and time, causing paths of objects (including light) to curve. Most obvious if massive, dense region
