By Ben • In this report you will find that a black hole is not a gravitational vacuum or a air sucking machine. If you want to find out what it is read this report What is a Black Hole? • A black hole is a object with massive amounts of gravity. Nothing can escape from a Black Hole including light. A Black Holes mass is concentrated at one point of singularity. At the Singularity itself the gravity is so strong it crushes the space time out of existence. Depending on the singularities mass, at a certain distance you will need the speed of light to escape. This distance is the black holes horizon which is its surface any thing that goes though the horizon is trapped inside for ever How does a black hole form? • A black hole forms when an objects gravity causes it to collapse to a small point. Stellar mass black holes form when a huge star cannot produce energy in its core. Radiation from the stars nuclear reactions to keep the star “alive,” gravity causes the stars core to eventually collapse. When the Black hole is formed the stars outer layers can be sucked into the black hole to make it heavier or can be blasted away into space. Astronomers don’t know how super massive black holes form, they think it might be when large clouds of gas collapse. Can you travel through a black hole ? • So far you can only travel through black holes in movies, but astronomers believe that there are wormholes that are theoretical “shortcuts” between two points in the space time continuum. Theories say that you would collapse as soon as you entered the wormhole. Will our universe become a black hole ? • It is unlikely that our universe will become a black hole, recent research shows that the universe is expanding at an ever increasing rate. The cause of this expansion, is called dark energy. No one knows what it is but astronomers believe that our universe will die slowly. If the dark energy didn’t exist it might have been possible for the universe to collapse on itself, pin pointing all of its mass to a very small point. Can anything every escape from a black hole ? • Nothing falls into a black hole can every escape from a black hole in the same shape that it entered. But sometimes pairs of particles appear into existence soon after this happens the particles cancel out on each other and vanish. But if this happens at the horizon of a black hole and one particle falls in and the other doesn’t they cannot cancel out on each other. In essence this is stealing a tiny bit of the black holes mass. If this continuously happened over billions of years the black hole might vaporize. • Now you know that a black hole is not a gravitational vacuum or a air sucking machine and it is a hole in space where a star has collapsed.
