What Are Black Holes?According to Dr. Stephen Hawking of Cambridge University UK, the pre-eminant theorist on this subject, black holes are an enigmatic concentration of matter formed when a giant star burns away its nuclear fuel and collapses into an object so dense its gravity allows no light to escape, thus rendering itself invisable.Other cosmologists suggest we can only see about 10% of our universe through such devices as telescopes, orbiting cameras and sound equipment. In the 90% that remains is the real mystery, the area known as 'Dark Matter.' Inside this 'Dark Matter' exists black holes. It is difficult to prove the existance of black holes because they are defined as what they are not. They consist of no matter, no space and no dimension. They only way they can be detected is using X-rays to detect the pulsars of radiation. The only trace we have of black holes, is what black holes leave behind. A good example of this is the disappearance of any stellar neighbours such as stars. |
