Black Holes

Nobody went to any black hole, I can tell you that. If anyone were to go into one, they would be spaghettifyed! Also, if anyone made it into a black hole and went down all the way and came back out to live to tell the story, they'd go down in history.

I don't know exactly what you mean by a kidney "hole", but the closest thing to that which might occur naturally is a cyst, which is like a hole with a membrane filled with fluid. These are common and do not cause death or diease unless the kidney is full of them, such as in polycystic kidney disease. A hole in the kidney caused by a gunshot or stabbing could cause death from bleeding.

There isn't an exact opposite of a black hole in terms of cosmic phenomena. Some theories suggest the existence of "white holes," which are hypothetical regions of spacetime where matter and energy are ejected instead of being pulled in, mirroring the behavior of black holes. However, white holes are purely theoretical and have not been observed or confirmed.

Both black hole and Big Bang singularities are points of infinite density and mass where known physical laws break down. They are both areas where gravity is extremely strong, leading to intense curvature of spacetime. Additionally, our current understanding of physics is unable to fully describe or predict the behavior of matter and energy within these singularities.

Sort of. It can be considered a dead star - one that no longer produces energy. At the end of their life, smaller (less massive) stars become white dwarves. These will no longer produce energy, but will continue to glow with their residual energy for a long time. After a long, long time - much longer than the current age of the Universe - they will stop emitting significant amounts of energy, and become black dwarves.

The gravity in a black hole is so strong that even light can't get out of it.

Nothing, with the exception of Hawking Radiation, can escape from a black hole. Effectively the gravitational force is infinitely strong.

Black holes are stronger than a thousand planets. Every planet they swallow, makes their power grow.

there is still no proper answer about the structure of a black hole,as because a black hole cant be seen.But according to assumptions the black hole spins around and thus its structure may be oval or spherical.Like anything thaat rotates, the black holes becomes flatter at the poles and broader at he equator

Cygnus X-1; Sagittarius A*

Actually, any observed black hole can be assumed to have been a star at some moment; although in the case of the supermassive black holes, it is not quite clear how they formed.

The 5Ws in "Holes" are Who (Stanley Yelnats), What (digging holes at a juvenile detention camp), Where (Camp Green Lake), When (present day), and Why (to build character and teach discipline).

Most micro black holes are predicted to evaporate through Hawking radiation, a process where they lose mass over time. The smaller the black hole, the faster it will evaporate. However, there are still uncertainties surrounding the exact mechanisms of black hole evaporation.

Black holes are also studied in physics, specifically in the field of general relativity. The study of black holes involves understanding their formation, behavior, and effects on surrounding matter and spacetime. Additionally, black holes are also of interest in the field of mathematical physics for their complex geometrical properties.

No, space junk cannot create a black hole. Black holes are formed through the gravitational collapse of massive stars, not by random objects floating in space. Space junk can, however, pose dangers to spacecraft and satellites in orbit.

There is no "deep core" of a black hole. Think of it as a one way tunnel. Matter is disassembled, sent through the "tunnel", exits the tunnel through a white hole (the other end of a black hole) Think of it as the part of a lawnmower which shoots out grass only when the grass comes out it is just a random assortment of particles. As to where the particles are sent... some scientists theorize that it is an alternate universe but no one knows for sure...

A peephole.

In Skyrim, the Black Star is a reusable, black soul gem that can hold both black and white souls. It is obtained by completing the quest "The Black Star." Black soul gems can hold the souls of humanoid beings, while white soul gems can only hold the souls of animals and monsters.

Neutrons stars are smallest stars in the Universe, with diameters of just 10-30 km! They are very compact and denese bodies, formed during a supernova explosion. When the tiny particles of the exploded star-atoms merge together, a neutron star is born. During this process of merging, electrons in the atoms are squeezed with protons, whch results in the formation of neutrons. This merging occurs because of the intense gravitational collapse. Once the star is formed, it is regular as any other star, barring its size and weight. It is so dense that is a sugar cube sized portion of the star would weigh as much as the people on Earth. It has a very powerful magmetic feild, and spins about 100 times a second.

A hole puncher is a tool used to create holes in paper or other materials, typically for binding or organizing documents. It works by pressing down on the handles to punch a hole through the material, allowing it to be easily placed in a binder or folder.

The ovary does not have a hole in the traditional sense. It has a small opening called the ovarian hilum through which blood vessels, nerves, and lymphatic vessels enter and exit. This hilum is not a hole like a cavity but rather a point of entry and exit for these structures.

If two black holes started pulling on each other simultaneously, they would accelerate towards each other due to the force of gravity. As they move closer, they would reach a point where they start orbiting around each other in a process called binary black hole formation. Eventually, they would merge into a single more massive black hole, releasing energy in the form of gravitational waves.

The collapse of a massive star in a supernova explosion can signal the formation of a new black hole.During this event, the core of the star collapses under its own gravity, forming a singularity and creating a new black hole.

First answer person:
Nope. It's a planet and planets don't have black holes in the center of them: a black hole at it's center would eat the planet quickly and move on to the next and the next and the ....

Second answer person (much handsomer):
hmmm....well has anyone actually seen the center of a planet to show there's no black hole?

Physicist Nassim Haramein, on the cutting edge of "fractal cosmology", mentioned in a lecture once that *everything* has a black hole at its centre (atoms, people, planets, etc).

I'm not a physics whiz so I'll lose an argument if you try and debate me; however I would suggest searching for his name and checking out what he's got to say. (I heard his theory on an 8-hour Google Video epic).

PS Check this out (part 2 of the video): http://video.google.com/videoplay?docid=6151699791256390335#docid=-1895475242307393956 ... right at the beginning he talks about a black hole at the center of the sun.

Scientists cannot view a black hole directly, but they can see the effects of the black hole in the surrounding space. For example, matter being sucked into a black hole emits radiation which can be detected, or a its gravitational effects on neighboring stars and dust.

no dude, the evidences of the existence of black holes is now widely accepted and i believe that black holes rules our universe but it is difficult to find them because black holes are nearly the perfectly black bodies

Yes, black holes are an example of negative pressure. This is because they exert gravitational force so strong that nothing, not even light, can escape from them, creating a region of extreme gravitational pressure.

Saving the full explanation of the processes of a star, just a short rundown: Stars are massive, so massive that their own gravity tries to collapse the star so it has to fuse hydrogen to exert an outward force to overcome its own gravity. During these processes, atoms are being stripped apart into free-floating nuclei, electrons and protons, accumulating in the core for the life of the star. When a star runs out of hydrogen fuel, it collapses and is stopped by the core getting hot enough to fuse helium (Product of hydrogen fusion), and that keeps happening up the atomic chain until the star starts fusing nickel, which requires more energy to fuse than is released, this is the end of a star as we know it.

If a star forms a black hole or a neutron star is dependant completely on the star's mass. If it is heavy enough, if will become a black hole, if not, then it will become a neutron star, where gravitational collapse is halted by the accumulated electrons in the core being compressed with free protons, bonding together to form neutron degenerate matter (Basically neutrons) and exerting an outward force that overcomes collapse. This force is known as neutron degeneracy pressure, courtesy of the Pauli exclusion principle of the Fermi-Dirac statistics. The principle states that no two fermions (Particles with a half-integer spin; quarks and leptons) can occupy the same energy state simultaneously, so you get an outward force.

Now if gravity were to overcome said force, the neutrons would then split into their individual quarks, resulting in quark degenerate matter and halting collapse, although very little is known about quark degeneracy or even how the matter splits into quarks. Then into the hypothetical preon degenerate matter and finally a gravitational singularity. Please note that very little is known about quark and preon degeneracy (The latter being generally not accepted as a viable model) as none have been discovered to date.

Finally, if the star wasn't heavy enough to form a neutron star, the core will decay into a large and hot ball of iron (Nickel decays into iron) and float, slowly cooling for the remainder of its existance or until acted upon by external forces.
