Answer 2

Having too much matter causes the star to explode , resulting in a supernova . The second type of supernova occurs at the end of a single stars lifetime . As the star runs out of nuclear fuel , some of its mass flows into the core . Eventually the core is so heavy that it can not withstand it's own gravitational force .
