This problem desire is very ambiguous, a cubic metre centimeter what meaning is the black hole? Want to know the bulk of the black hole does not represent the substance of the black hole, it is a space only.
The black hole is a kind of special celestial bodies, actually the circumstance in the black hole not by human place acknowledge, existent theory is entirely in the black hole invalidation, because center of theoretic black hole just surprises,this is dot, the strange place of an infinite and compact infinitesimal infinite curvature.
This strange place does not have bulk, that is to say the substance of the black hole does not have bulk. The black hole that people observation goes to just has the space of an absolutely empty, once enter this airspace, the line that connect light cannot escape.
Because be below the strange place effect of black hole center,this is, produced an incident visual field, namely Shi Waxi radius, the unify the whole country of black hole gravitation is inside this radius limits, any objects enter this visual field, come to naught.
Black hole substance - surprise that namely what did the dot turn into the thing, scientific group is indecipherable, the strange point that resembles big burst is same, not be we are this spatio-temporal thing.
Material condensed the utmost come to naught to become overtime empty, the mankind is indecipherable.
Some scientists think to be one kind calls quanta vacuum the thing inside strange place, this thing dangerous is gotten very, minimum plays dinkily meaning the energy that can accommodate maximal. This kind of hypothesis cannot test and verify.
So the quality of the black hole surprises besides the center dot, whats don't have the area of absolutely empty weather of radius of alleged Shi Waxi, after matter drops into this space, with respect to can fast Xiang Ji the point drops, the simplest thing becomes finally in strange place, what go in without giving thought to is what material, the original message that its carry can disappear.
Understood now? Prime cut does not give the black hole an one cubic metre centimeter play meaning come out.
The black hole that we see now is great quality celestial bodies after supernova happening to explode greatly when death, abandon periphery material, the center is compact corporeal collapse shrinks formation black hole.
The sidereal death of a quality of about 30 suns ability is possible collapse shrinks black hole, the star of quality of sun of a 8 times above, dead hind can form heavenly body of a neutron only commonly. The quality of neutron star exceeds money heart to pull a place of strategic importance to block quality limit to be able to continue collapse shrinks black hole.
The black hole begins very won't big, after forming, suck ceaselessly indigestion all round celestial body material, appear even the setting that the snake swallows an elephant, a small black hole is met drag get down a tremendous star.
Such black holes are met bigger and bigger, our galaxy center " Sagittarius A " the quality of the black hole, have 4 million times sun quality. The largest black hole that discovers at present in the universe calls SDSS J140821.67+025733.2, its quality is 18 billion times of the sun.
This universe small black hole has only too first black hole, there just can be a few very small black holes at the beginning of the universe explodes greatly namely, but this just exists one kind theoretically, up to now, the mankind still is planted to this without observation hypostatic.
If the world is so great the black hole of quality, its Shi Waxi radius has 8.86 millimeter only, the black hole of so great quality can have the sun the Shi Waxi radius of 2.952 kilometers.
Its computation formula is:
If inscribe advocate the black hole with means so small world is close to the earth to meet how, empty in those days communication tells you, can eat off the earth slowly of course.
If have a cubic metre really centimeter the black hole eyeshot of bulk, namely the black hole of Shi Waxi radius, ask everybody to remember, this black hole is not so big black hole substance absolutely, however the incidence of the black hole.
Although substance of so little black hole center still does not have the strange place of bulk, one cubic metre centimeter the limits that is its gravitation influence only.
This black hole should stand by the earth only, must stand by the earth completely, radius relies on this Shiwaxi on the earth directly, just can arise to earthly material suck accumulate action. Smaller black hole is sucked indigestion slower, because this kind of 1 centimeter small black hole is sucked,accumulate begin to meet very slow, increase of quality ceaselessly as engulf, suck indigestion can add gradually fast.
This kind of black hole not only can suck accumulate the earth, if stood by the sun to still can be sucked,accumulate the sun, pass finally eat off 34 suns, become a black hole that achieves quality requirement truly. Because till the mankind is current till, the black hole that discovers quality is the smallest has 3.8 about times sun quality.
So small nevertheless black hole should eat off the sun to may want very long time, smaller black hole is sucked indigestion jump over relatively slow.
The miniature black hole of theoretic prefabricate can be formed in large collidor, but because the black hole is too small too small, great majority has not been sucked before accumulating with respect to be frightened out of one's wits (evaporated) .
The scientist is forecasted, although black hole of this kind of miniature can be sucked indigestion, absorb a proton to need 100 hours, absorb 100 proton to need 1 year, and absorb 1 milligram material to be about day moorland became old, cosmic destruction also has not been absorbed.
So a lot of people worry about prefabricate black hole to be able to destroy the earth and mankind, not was necessary completely.
And this kind of small black hole, include the black hole that Shi Waxi radius goes to 1 centimeter half centimeters, never had been discovered up to now.
Spatio-temporal communication viewpoint, the welcome is commented on discuss.
