blackholes
Stars are affected by two main forces: Nuclear fusion, and gravitation Black Holes are the result of an imbalance of these two forces.Nuclear fusion- the outward force from the star's centre and gravitation- the force pulling inwards. These two processes balance one another until all the star's hydrogen is exhausted, allowing gravitation to take over. Once gravitation dominates, the star becomes unstable and starts to collapse. As the core compresses, it heats up and results in a supernova explosion in which the material and radiation blasts out into space. If what remains of the star is greater than 3 times the mass of our sun, it will continue to collapse and form a black hole. Albert Einstein's theory of general relativity suggests that the most densest and massive objects conceivable, such as black holes, have gravity that is so strong that nothing, not even light, can escape their grasp. I do not fully understand Einstein's general theory of relativity but I'm going to try and
Therefore we cannot see beyond the event horizon, because according to Einstein nothing can exceed the speed of light. The fundamental aspect of general relativity is effect that matter, with a gravitational field, has on the curvature of space, rather on the four dimensional space-time. Thus when something enters the event horizon, it will vanish without a trace. Consider the rubber sheet example again except this time a heavier but more condensed weight is put on top. Before something reaches the singularity it is torn apart by intense gravitational forces. When we describe the position of a flying plane we can use length, width and height these make up the three dimensions of space. The image of several stars behind the sun had shifted so that they were visible to astronomers on earth. This makes a huge depression in the sheet resembling the effect that a large mass will have on the curvature of space-time. , 1992)So why have I gone on about general relativity and space-time. The radius is named after German astronomer Karl Schwarzschild, who derived the first model of a black hole in 1916. In other words the escape velocity from the event horizon must be greater than 'c' the speed of light. If one now rolls marbles on the rubber sheet, their paths will be curved, rather than being straight lines. The SingularityAccording to the General Theory of Relativity the Singularity is a point of infinite space time curvature.
