![]() Since the speed of light is, according to the relativity theory, the maximum possible speed, nothing, not even light, could escape the black hole once it is inside the event horizon. Suppose a Blackhole appeared just 1cm from Earth,will Earth be safe or will Earth be sucked into the Blackhole?īlack holes are formed as the result of the collapse of a very massive star at its death. But let´s assume that they do, then the huge gravitational field of the black hole would surely atract the Earth towards the black hole.īlack hole absorbs everything into it.Mass cannot be destroyed.So where do it go?Why don't we think of a star evolving from a black hole?īlack Holes may form as the result of the collapse of a very massive star at its death. All the matter of the star's core is crushed to an infinitely small point, a singularity. ![]() Now, although it is true that mass can't be destroyed, it can be transform into energy (that's the meaning of the famous equation E = mc 2). Black holes may be an important source of gravitational waves, and may also be important for helping other stars to form. All of the mass of the star from which the black hole was formed is still there, maybe even mass from more than one star! For example the gravity of black holes (like other large stellar objects) may promote nebulae to form stars. What is the absolute fate of a Black Hole ? In 2002 it was discovered that the stellar-mass black hole called GRO J1655-40, is moving across space at a rate of 250,000 miles per hour, four times faster than the average velocity of the stars in that galactic neighborhood! More information here. I don't think there is anything considered "absolute" regarding black holes. One of the hypothesized fate of a black hole depends on the temperature of its surroundings. If the universe is cold enough it will evaporate incredibly slowly. If the background is warmer it will grow slowly until the temperature drops low enough for the hole to start to evaporate. If not even light can escape a black hole,it means that they are invisible. Then how do we know that there are black holes ?īlack holes can be observed through its interaction with other matter, for example, by tracking the movement of a group of stars that orbit a region in space. It will continue to shine until the kinetic energy of the atoms diminishes enough to stop radiation emission - it will then be a black dwarf - a cold mass moving through space.This animation is a simulation of gravitational lensing caused by a black hole.ĭoes the SINGULARITY of a black hole have any mass and is the universe infinitely vast ?Īccording to the theory, at the center of a black hole lies the singularity, where matter is crushed to infinite density. Such a collapsed star, at its life's end, is called a white dwarf. When the fuel runs out completely the crushing force of gravity makes the star collapse under the force of its own weight. The star begins to run out of hydrogen - its fuel for the fusion process - and swells to become a red giant. Only small and medium stars end up being a black dwarf - very large stars undergo a supernova explosion. (c) Describe what happens to a star, after the main sequence period, for the star to eventually become a black dwarf.Īfter the stable main sequence period the star is effectively dying. ![]() In the future we may have developed technology and theories that will allow us to calculate the mass. (iii) In the future, it may become possible for scientists to calculate the mass of Betelgeuse. They use information from the stars to make an educated guess. They do not have a method to measure mass of stars. (ii) Suggest one reason why scientists can only estimate and not calculate the mass of Betelgeuse. What will happen to Betelgeuse at the end of the red super giant stage? (i) Betelgeuse is in the red super giant stage of its life cycle. They estimate that the star has a mass between 8 and 20 times the mass of the Sun. ![]() ![]() Scientists cannot calculate the mass of the star Betelgeuse. (b) Scientists can take the measurements needed to calculate the mass of many stars. K and L are much larger than our Sun, they will follow a different route. Our star - the Sun - and others of its size or smaller will follow the same route. Which one of the stars, J, K or L, will become a black dwarf? Give a reason for your answer.

You can use number formatting to remove the values after decimal point. To calculate elapsed time in days, the formula is simple =TODAY()-A1.
