Do you think it's possible that man will ever venture directly into a black hole, survive, and report the experience?

No, I don't think so, because the nearest black hole exist so far that a man will have to get thousands of lives to get there. I am providing you with some basic Facts of a Black Hole. You can decide your answer yourself.

Black Hole is an extremely dense celestial body that has been theorized to exist in the universe. The gravitational field of a black hole is so strong that, if the body is large enough, nothing, including electromagnetic radiation, can escape from its vicinity. The body is surrounded by a spherical boundary, called a horizon, through which light can enter but not escape; it therefore appears totally black.


The black-hole concept was developed by the German astronomer Karl Schwarzschild in 1916 on the basis of physicist Albert Einstein’s general theory of relativity. The radius of the horizon of a Schwarzschild black hole depends only on the mass of the body, being 2.95 km (1.83 mi) times the mass of the body in solar units (the mass of the body divided by the mass of the Sun). If a body is electrically charged or rotating, Schwarzschild’s results are modified. An “ergosphere” forms outside the horizon, within which matter is forced to rotate with the black hole; in principle, energy can be emitted from the ergosphere.

According to general relativity, gravitation severely modifies space and time near a black hole. As the horizon is approached from outside, time slows down relative to that of distant observers, stopping completely on the horizon. Once a body has contracted within its Schwarzschild radius, it would theoretically collapse to a singularity—that is, a dimensionless object of infinite density.


Black holes are thought to form during the course of stellar evolution. As nuclear fuels are exhausted in the core of a star, the pressure associated with their energy production is no longer available to resist contraction of the core to ever-higher densities. Two new types of pressure, electron and neutron pressure, arise at densities a million and a million billion times that of water, respectively, and a compact white dwarf or a neutron star may form. If the star is more than about five times as massive as the Sun, however, neither electron nor neutron pressure is sufficient to prevent collapse to a black hole.

In 1994 astronomers used the Hubble Space Telescope (HST) to uncover the first convincing evidence that a black hole exists. They detected an accretion disk (disk of hot, gaseous material) circling the center of the galaxy M87 with an acceleration that indicated the presence of an object 2.5 to 3.5 billion times the mass of the Sun. By 2000, astronomers had detected supermassive black holes in the centers of dozens of galaxies and had found that the masses of the black holes were correlated with the masses of the parent galaxies. More massive galaxies tend to have more massive black holes at their centers. Learning more about galactic black holes will help astronomers learn about the evolution of galaxies and the relationship between galaxies, black holes, and quasars.

The English physicist Stephen Hawking has suggested that many black holes may have formed in the early universe. If this were so, many of these black holes could be too far from other matter to form detectable accretion disks, and they could even compose a significant fraction of the total mass of the universe. For black holes of sufficiently small mass it is possible for only one member of an electron-positron pair near the horizon to fall into the black hole, the other escaping. The resulting radiation carries off energy, in a sense evaporating the black hole. Any primordial black holes weighing less than a few thousand million metric tons would have already evaporated, but heavier ones may remain.

The American astronomer Kip Thorne of California Institute of Technology in Pasadena, California, has evaluated the chance that black holes can collapse to form "wormholes," connections between otherwise distant parts of the universe. He concludes that an unknown form of "exotic matter" would be necessary for such wormholes to survive.

First of all a black hole is not a HOLE! So you can't go through it. A black hole is believed to be a giant collapsed star that is so dense not even light can escape. The theory is that the gravitational pull is so strong that if a person approched it the difference in pull between your head and your feet is so great that it would stretch you out like a piece of spagetti, then when your feet finally hit bottom it would squash you thinner than a pancake. Of course if you think you can survive that remember that you would have to be lighter and faster than light if you wanted to leave. So to answer your question "NO" but I do know a few people that I would like to see try it anyway.

no all matter sucked into a black hole is destroyed and if it does survive it'll end up in someother place int the univers which means al there traveling instruments will not work there and they will not be able to get back to earth or any known colony of earth, but i'd say it is a %99 chance they will die in the vortex, so i doubt anyone wouldeven volunteer to go into the black hole, but instead someone or something like a satelite may accidently go into it if it got too close as our reach expands farther into the universe

go into a black hole : perhaps, if the man is unlucky enough

survive : certainly not. the gravitational and tidal forces would crush him before he even gets close to it.

report the experience : if he can't survive, then no... and even if he did survive, he wouldn't be able to send even a message out of the black hole (light can't get out, therefore no communications), let alone himself.

No. Once you enter a black hole, the forces tear you up, fry you, and will melt even the hardest metals and even diamonds. Once you go through that, you will be pulled in, and wont come out for a loooooooooooooong time.

Never, Not ever possible, No, Nein, Nyet. In fact in the black hole the laws of physics as we know it probably cease to exist.

no,
you would be crushed before you even got close to it.

every atom in your body and spaceship would be extruded into a single atom wide strand of spagetti as you exponentially accelerated toward the black hole. Nothing, no matter, let alone life, can survive it.

this will probably be false as when things pass near the black hole, that thing will be sucked into it as the black hole has a very very very large gravitational force
deep inside the black hole, it will also accelerate and you will be burnt up into ashes within seconds

no not possible at all.. first of al mankind has discovered blackhole but not seen one cuz it cannot b seen as it absorbs everything wich passes thru or above it even light..
dats why no one cn c it..
but its presence can b detected by wavering of orbits of odr heavenlybodiesor stars near it..
black holes have immence gravity and can absorb a whole sun.. so i think no human wud lke 2 go dere..
hope dis solvd ur prob

I think it is humanly impossible... even light cant pass through a black hole, what more a mere man?
