INTRODUCTION TO BLACK HOLE Black holes are objects so dense that not even light can escape their gravity, and since nothing can travel faster than light, nothing can escape from inside a black hole.
Due to supernova explosion, which results in formation of protostar , which is mainly composed of hydrogen molecules.
As the compression continues, the temperature increases, causing the hydrogen molecules to disintegrate into hydrogen atoms and finally electrons in hydrogen atoms separate from protons, or ionize. This is called a plasma .
As the compression continues, the centre becomes so hot that nuclear fusions begin.
SUPERNOVAE EXPLOSION More massive stars tend to burn hotter and faster. Once all the nuclear fuel has been exhausted, such stars quickly collapse, shedding much of their mass in dramatic explosions called supernovae .
