114.Pulsars could not be pulsating stars because the pulses too : 1777255
114.Pulsars could not be pulsating stars because the pulses are too short.
115.We expect neutron stars to spin rapidly because they conserve angular momentum.
116.Many pulsars have periods that are gradually increasing as the spinning neutron stars lose energy.
117.The event horizon marks the boundary within which the density is roughly the same as that of the atomic nucleus.
118.Theory predicts that neutron stars may not exceed 3 solar masses.
119.If the accretion disk around a black hole emits X-rays outside the event horizon, the X-rays can escape.
120.To tell the difference between a neutron star and a black hole in an X-ray binary, we must find the temperature of the object.
121.LMC X-3 is a binary system that is believed to contain a black hole.
122.A scientific theory can be proven true if the correct experiments are performed.
123.When a star of mass comparable to the Sun dies, it becomes a black hole.
