Let us calculate the quality that calculates a black hole first.
Graphic representation: Black hole
The black hole is noumenal size is how old after all, one does not have the strange place of bulk, still be one has the place of the minorrest volume, still be an unknown. But no matter black hole noumenon has after all how old, when discussion black hole, the most important parameter is the quality of the black hole, the quality of the black hole is greater, its incidence is bigger, what this incidence points to is the incidence that that Lian Guangdou cannot escape, this limits is called the eyeshot limits of the black hole.
Graphic representation: Sketch map of limits of black hole eyeshot. Smooth from be passed near the black hole, if rely on a black hole too close, meet by black hole capture, when the place is proper, light cannot escape namely, won't be absorbed by the black hole again, will rotate around the black hole, become a black hole " satellite " , because this becomes you to travel in aerospace, from darkness one enters the place with a dazzling ray suddenly, that is feel sorry, you just entered black hole visual field probably, and you cannot have turned round.
The eyeshot limits of the black hole, can count the black hole dominates a field absolutely, this control domain has volume of course, because this area can regard as completely a perfect sphere, the bulk formula of sphere is:
Since the black hole controls a domain to be 1 cubic metre absolutely centimeter, so the radius R = 0.62 of limits of eyeshot of this black hole centimeter =6.2*10^-3 rice. Checking computations: 4*3.14*0.62^3/3 = 2.9933/3 approximates 1 cubic metre centimeter. And the eyeshot limits radius of the black hole, it is famous black hole Shi Waxi radius, know this radius, with respect to the quality that can know a black hole.
Graphic representation: The computation of Shi Waxi radius of the black hole is formulary, among them C is vacuum velocity of light, every second 300 thousand kilometre, g is gravitation constant is 6.67*10^-11 (M3kg-1s-2, these are international units, need not be in charge of, want all numbers to calculate by international unit only go)
According to this formula and radius R, the quality that can roll out a black hole instead is:
4.18*10^17 kilogram.
This number is too large, we must look for a thing to come below analogy, compare with the moon for instance.
Lunar quality is 7.36*10^22 kilogram, so an one cubic metre centimeter the quality of the black hole is equivalent to 1/100000 moons only. This means this black hole is one confuses your black hole merely.
Before confusing your black hole to be brought up in it, harm sex is very small. If this confuses you,the black hole is slow merely stand by the earth, a when the world becomes after then it is captured completely possibly by earthly gravitation invisible satellite.
Graphic representation: Confuse your black hole to be able to solve dilemma of earthly energy resources
But the earth has to confuse satellite of your black hole, likely to present earthly person not be good thing, because become,the meeting when the black hole gobbles up the asteroid that stands by it and interstellar dust releases a large number of energy and radiate, cause disaster to environment of earthly modes of life and relation to their environment, because it leaves the earth too close. Nevertheless, if,one confuses satellite of your black hole can be apt to is added use, become the puppet that solves human society to expand energy demand possibly also always motive.
Complement, have game of an universe sandbox, there is carry out on Steam platform, this software can help your imitate the influence of black hole of a miniature to the earth.
