Question

astronomers say that if a person enters a black hole, he hits the singularity.however, if its actually viewed, he disappears.WHY??

actually, he seems to disappear,but actually revolves inside the black hole...

Answer 1

The spatial singularity is a theoretical term for the state of the center of a black hole. It would occur if matter could be compressed to infinitely small proportions, a mathematical point. This is the prediction of General Relativity if there is no physical limit on the size of particles. This has nothing to do with the formation of an event horizon, which occurs as soon as the infalling matter is all inside its Schwarzchild radius, a relatively long time before it falls to the center.

Because nothing other than extremely random Hawking radiation can escape from beyond the event horizon, there is no way to observe the core of a black hole, whether or not it is a singularity. The only physical properties we can currently apply to a black hole are mass (measured by the strength of the gravitational pull), volume (calculated in three dimensions using the Schwarzschild Radius), electrical charge, temperature, spin, and magnetic field.

Answer 2

Noone will ever reach the singularity. Actually, it's impossible for anything to ever reach the singularity (under our current model anyway).


You will be destroyed before even reaching the event horizon of a black hole (nowhere near the singularity) in any case by tidal forces.


It might be possible to send a very well built machine into the black hole with a camera on it, which might be able to cross the event horizon of a supermassive black hole...but, it will be destroyed instantly as it crosses the event horizon, so you will never see the singularity (Right before the ship is annihilated it will probably see a giant flash of light).



These 'astronomers' are assuming you are not destroyed by tidal forces (which will never happen). If you could pass through the event horizon freely then yes, you would disappear from view if someone was watching you. This is because you cannot see beyond the event horizon from outside of it as no light can escape from it.

No one would survive inside the core of a nuclear furnace . when the stars enter in to the stage of a blackhole , it gobbles up eerythig around it - even massive planets are sucked in and burned to abd turned into a lava inside the core of the star undergoing nuclear reaction.No life can survive even anywhere around the star within its gravitational field .the intensity of its gravity is said to be so grea ha even light can not escape its field of gravity.The only thing that can escape from the star is its gravitational force , besides the radio active rays .Singularity is not any magical or special stage or charcter . It simply means that that something tha is not seen or found in anything else , It is a peculiarity that exists noehre or in nothing else. It is an absolute character the like of which is not exisring anywehre else. So he burning to ashes of any hing and everything inside a nuclear furnace is not a singularity. The gravitational force of the massive bodies is a singularity and it atracts eerything without eception whereas magnets attract only iron and the magnetic force has two different polarity and the like poles repel and it is only the unlike poles hat atrac each other. But gravity atracts everything with9out exception and it does not repel anything , Gravity atracts gravity too . so it is a singularity , the equal of which is not present anywhre and in anythng else .Light is supposed o be the fastest thing o travel . But gravity is faster than light and its speed is unascerainable . it is just instant and it won[ be possible for hmans to measure its speed a anytime for it is not in the form of any wae or paerticle as in the case of light .Speed is limited by the mass that the travelling object gains with the increase in speed . But gravity being neithere a wave not a particle , the question of its increasing in mass with he increase in spedd does not arise , And so its speed is insant and immeasureable too..This is its singularity . Sp also the boundlesscharacter of space is a singularity of the space as space being nothing - emptiness , it has he singularity of being the only thing that has no bounds or limits .

Answer 4

In a typical sized black hollow that doesn't have an electric charge and does not rotate, the tidal forces are susceptible adequate that an merchandise can fall deep interior the black hollow earlier it fairly is torn aside. The gravity on the backside a million/2 of the object is more suitable than the gravity on the precise a million/2 which attracts the object in opposite instructions vertically. the object is concurrently overwhelmed horizontally resembling a rubber band being pulled. Astrophysicists consult from this technique as spaghettification or the noodle result. approximately one 10th of a 2d earlier the object reaches the critical singularity, the place area and time now no longer exist as all of us be attentive to them, the object could be torn aside. this could happen greater or less interior the comparable spot in spite of the mass of the black hollow. no one fairly knows what happens to count after it fairly is torn aside and regrettably there fairly isn't a thank you to define out what precisely happens yet. based on the predictions approximately black holes, we'd be no longer able to deliver a probe or another style of unmanned motor vehicle right into a black hollow.

Answer 5

Black Hole is a highly condense matter which tends to swallow everything that comes in its way... no matter how big or small it is like even galaxies can go inside a black hole and never return back. There is intense force inside a black hole that once anything which goes in it, cant come back even the light / radio waves are absorbed and not reflected.

There is still a great study being done to know the exact nature of the black holes.

Answer 6

Nothing can penetrate the surface of a black hole because it would have to travel faster than the speed of light. This brings up the question "Then how can a black hole be"?
It cannot exist!

Answer 7

Because, once he passes the 'event horizon' no light can escape and they 'vanish'. In actuality, tidal forces would tear him apart long before he hit the event horizon ☺

Answer 8

blackholes are caused due to very strong gravitational field.this gravitational force is so strong that light is absorbed into it.hence black hoes are black. this blackholes has power to absorb sun.
