Ok, black holes... First, where do they come from?

When a giant or supergiant star reaches the end of its fuel supply (hydrogen), it goes through a complicated process where it starts to fuse helium atoms, then the oxygen created out of that fusion, and if it is big enough, it will actually fuse the oxygen atoms into carbon for a millionth of a second (at about 1 billion degrees kelvin!) before the star collapses. All these different fusions creat didifferent layers in the core (the outermost fusing the remaining hydrogen and the innermost fusing the oxygen).
at one point, the pressure of the fusion actually overcomes the gravity of the star, and sets off the chain reaction of a supernova. All of the layers of the core implode in on themselves, gaining momentum with each layer. In some stars, the pressure becomes so great by this collapse, that the atoms actually strip off their protons and electrons, leaving just the neutrons to become a "neutron star." A neutron star is so dense, that a spoonful of material from it would weigh as much as mount everest.
Even fewer stars go beyond this point and colapse even further to become a black hole. the fabric of space time itself rips, allowing a point of infinite mass to exist.

Now, some black hole behavior

If black holes are well... black, how can we spot them? or even know they exist? Well, actually there are many ways. Most black holes come with something called a quasar, a disk of gas, dust, and light energy spinning around the black hole before it gets sucked in. As the matter approaches the event horizon (or point of no return to the known universe) It moves faster and gets hotter, emitting more energy.

Another strange property of black holes is their gravity is so strong, they can actually bend light (even though it is energy, light has some properties of matter) This lensing effect is useful in many ways. As a black hole passes between us and a distant star, it will bend the light in such a way, that we will see four of the exact same stars, equidistant from each other (even though only one star is actually there). Based on the brightness of the star, and how far apart the "clone stars" are spaced, we can determin how far away the black hole actually is from us.
This lensing can also act as a natural telescope, allowing us to look at light farther away than what our telescopes are capable of sensing (the galaxy cluster Abell2218 is a classic example of this lensing effect, allowing us to see 11 billion light years away)

Finally, once matter passes beyond the event horizon it is accelerated to near light speed and exposed to unimaginable gravity vectors. This causes the matter to emit x-rays which jet out of the black hole perpendicular to the quasar disk. In nature, it is hard to produce X-rays like this, so seeing a jet of X-ray radiation is a dead giveaway of a high enery (or energy producing) object

A trip through a black hole, as described by Steven Hawking

If you were somehow capable of surving the intense heat and radiation from the event horizon, your trip to the black hole would certainly kill you. As you approach, gravity tides would pull harder at your feet than your head would stretch you out like a strand of spaghetti, until you snapped in half; then those peices would be stretched out until they subdivided, and so on and so on until you are stripped down to your very atoms. As you approach the singularity (point where the black hole exists) it becomes brighter and brighter as you see more and more light and radiation trapped by the pull of the black hole. If you aren't atomized by now, you are vaporized by the intense heat and radiation. The lucky atoms become so energized that they are in fact converted to X-ray radiation and are able to escape the black hole, while the other atoms are sucked to the singularity and lost from the universe forever..........

But matter can't be detroyed?! Steven Hawking says to compinsate for this "lost matter", other parallel universes exist, where the black hole may, or may not exist. This means the matter still exists in that universe, even though it may be destroyed in this one!



Lastly, a recent discovery that has redifined the very definition of a Galaxy

The core of a galaxy has always been a misterious place for astronomers (us being located on the outer region of the ilky way). Intense radiation, dust clouds and dense star fields are expected to be found. But a decade or so ago (not really sure) a supermassive black hole was discovered in the center of the Andromeda galaxy (closest galaxy to the milky way). Soon, supemassive black holes were being found in all galaxy cores (including our own), making scientists rethink the evolution of a galaxy from the big bang.

At the begginning, a huge dust cloud begins to condense on itself. the densist part pulls in soo much material, a star is only briefly formed, creating a black hole. the pull of the black hole forms many stars in the gas clouds around it. eventually, so much stuff falls into the quasar, that the radiation begins to push the dust and stars away, stopping the black hole from consuming the infant galaxy. When galaxies collide, their black holes merge and become even bigger. The biggest black hole ever discovered is about the size of the earth.


So hopefully you understand how black holes work now
