Black holes

What happens if you are traveling to a black hole? Will extend your body and then pulls into parts and torn apart, what a black hole? What is known about black holes?

Black hole: is a final stages of potential star, when stop fusion reactions in the heart of a star mass greater than the sun 20 times collapses heart star forever, and accumulate mass in the smallest size, and this is called the body micro-density micro in old age "Body singular" (exceptional), and be a tremendous force of gravity on the body must not escape from something so light, you know this black hole region.

Nothing can escape from it, In 1917 German scientist Shoartzchild - mathematically - the possibility of the existence of black holes, has been used a solution to Einstein's theory of general relativity to describe the properties a black hole, and derived a formula for the radius is called radius ٍShoartzchild, can not light nor the substance of impunity the force of gravity through it, and expresses radius Shoartzchild relationship: -

Rs = 2GM/c2

Where represents G fixed Newton attractions cosmic, and M block black hole, and C the speed of light, known as the edge of the ball that radius Rs horizon event, and escape velocity at the event horizon is equal to the speed of light, and that there is nothing going capacity greater than the speed of light, The objects that are close to this region can not survive or escape.

Signs directly and indirectly: of black holes three properties can be measured in theory, are: mass, angular momentum, and electric charge. It can determine the mass black hole through the field gravity generated, calculated mass using a formula rate for Law Third Kepler in the movement of the planets, studies have demonstrated (NASA) that a black hole is about the same as the stars and the planets; and spins the black hole because it retains momentum angular star who be it.

Scientists assumed that a black hole can be shipped electrically when it falls a species excess electrical charge, despite the inability of scientists to measure now shipped bowed, also possible to detect X-rays from high temperature gases emitted from it.

Although we do not know everything about black holes, but there are signs directly and indirectly on the existence, and will result in continued research and special missions to a greater understanding of the reality of black holes.
