This text was about Neutron stars. A Neutron Star is when two stars die and explode and then they collide. Did you know that one teaspoon of a neutron star is 900 times heavier than the largest pyramid in Egypt? Did you also know that gravitational waves and light are the same speed? I now understand what a neutron star is. I also understand that neutron stars are very heavy. How do stars reach the end of their lives?
