The short answer is that whenever we take a good hard look at any given galaxy, we find good evidence that there is, or could be, a black hole at it's core.\n\nThe long answer is:\nIt is not so much a theory as something being increasingly noticed. Because black holes are the latest and coolest thing in astronomy (just look how many questions about them appear here!), everyone is always looking for them. They are not so easy to find because, well, they are black. You can't see one directly. One way to tell if there is a black hole there is by the effects of it's gravity on nearby matter. So far, the biggest effect observed on nearby matter has been high energy radiation caused by the rapid acceleration of that matter as it falls into the black hole. Some galaxies show that in their core, indicating a massive black hole there.\nAnother effect is that stars could orbit the black hole, just like the Earth orbits our Sun. We have known for a long time that all stars in a galaxy are orbiting around the center of that galaxy. IN the past it was assumed that there were enough regular stars and dust and gas in the center of the galaxy to make a mass big enough to orbit around. But recently observations with more powerful telescopes of stars closer and closer to the center of our Milky Way galaxy have shown stars VERY close to the center of the galaxy orbiting VERY fast. In that case it is easy to calculate the mass of whatever it is that they are orbiting, just like we can calculate the mass of the Sun by knowing how fast the Earth orbits it. Those calculations show the mass is millions of times more than the sun. Now we know all that mass has to be in an area smaller than the orbits of those stars, and the size of those orbits is measured as being quite small, so we know the volume far too small to be a big star cluster or other ordinary concentration of mass. The only known way to get so much mass in such a small volume is a black hole.\n\nI recall many years ago, when computers were just becoming powerful enough to do big simulations, that someone tried to simulate a globular star cluster by programming a few thousand stars to orbit in a big ball with no mass other than the stars themselves. It didn't work. The stars kind of just all dispersed at random and did not stay in a nice ball shaped globular cluster. Now it should be obvious that if there was a massive black hole in the center of the globular cluster, then all the stars could orbit it like the planets do the Sun, only not all in one plane like the planets do. And I believe some evidence of medium large black holes has been found in some globular clusters recently by the same method of using powerful telescopes to look at the orbits of stars very close to the core. And after all, what is a globular cluster but a really small galaxy.\n\nSo giant telescopes, some of them is space, are providing data never before available that just makes it more and more reasonable to assume that all galaxies have a massive black hole at the core.

The heaviest insect is probably the goliath beetle (Goliathus goliath) of Africa, which is reputed to weigh up to 100 grams (more than a small bird)!

Any mass contained in a radius smaller than its schwarzschild radius,\n\nr_s = (2GM/c^2) with\n\nc= the speed of light, G = the gravitational constant and M is the mass of the object.\n\nThe schwarzschild radius scales linearally with mass (an object twice as massive will have twice the schwarzschild radius) and to get you started, an object the mass of the sun (2x10^30kg) has a Schwarzschild radius of 3 km. In otherwords, if you jammed the sun into a sphere 6km across, it would be a black hole. The schwarzschild radius indicates a volume of space where the escape velocity from the mass in question is the speed of light or greater. Using the linear scaling, an object the mass of the earth (6(?)x10^24 kg would have a schwarzschild radius of about 1/300,000 of 3km, or 1 cm.\n\nBlack holes have some peculiar properties, such as evaporation, extremely strong tidal forces near their central singularity (but weak tidal forces at the schwarzschild radius of a supermassive black hole). Things can happen inside of the schwarzschild radius too. For instance, if our universe was closed (not expanding enough to continue expanding forever) it is technically inside of its own schwarzschild radius (we would be living inside a huge black hole.)\n\nIt is called a black hole because no light that crosses the schwarzschild radius can completely escape the mass to an infinite distance. (This does mean that if you are just outside the schwarzschild radius yourself, you CAN see light that is emitted from within it, or passes within it as long as it is not too close; only an observer at d= infinity cannot.) Thus this volume of space appears "black." You can read more about black holes on wikipedia at http://en.wikipedia.org/wiki/black_hole....\n\nThe concept of an object with gravity so great was first conceived by a little known geologist named John Michell. The better known Simon Laplace took the idea and ran with it in a book years later and so is often credited with coming up with the idea.

Smartie pants?\nEvidence points to a massive black hole at the center of the galaxy (Milky Way).  The black hole, with a mass more than three million times that of our sun, would appear to be in the constellation of Sagittarius.

The gravitiational lensing of the Sun is very weak.  The images of stars behind the Sun move only a few seconds of arc at most, and the main effect of the Sun as a gravitational lens is like a very weak magnifying glass with the center blocked out (most of the stars behind the Sun are still blocked).\n\nBut your question could just as well be asked of a strong gravitiational lens like a Black Hole, and in that case it is an interesting question.  I believe the answer is "no, a gravitational lens cannot superpose the images of two objects".  This is more a statement of optics than of gravitational lenses---in other words, no lens, glass or gravitational, can superpose two points in the field.  A gravitational lens does, however, make multiple images of a background star.  There are rules about these images---there must be an odd number, usually 3.

A black hole is a concentration of mass great enough that the force of gravity prevents anything past its event horizon from coming out of it. A black hole may be a huge star more than 6 times the mass of sun or other huge concentrations of matter.\n\nIt has a gravitational field so strong that nothing even light,the fastest thing known to humans cant escape from its garvitational power. for more try http://en.wikipedia.org/wiki/Black_hole

Just about all astronomers agree that at the center of our Milky Way Galaxy (and probably at the center of most other galaxies) lies a supermassive black hole. It probably has a mass at least 2-million times that of our Sun, and is approximately 96-million miles in diameter.\n\nThese figures come from careful observation and measurment of the motions of other objects near the galactic center.\n\nThis page has more info, plus a photo ---\nhttp://antwrp.gsfc.nasa.gov/apod/ap021018.html

As moses said very well indeed, Nobody knows.\nThe major problem I have with a black hole is why it is called a black hole. If this thing is so dense and gravity is so powerful it would be bending light around at the event horizon so that you'd not even know the black hole is there. The other way to confirm this "black hole" would be to observe the planets remaining in the solar system still rotating around a sun which is not there any more. What you would actually confirm would be, according to the laws of gravitational attraction that two massive bodies are attracting each other. One is the planet you see and the other is the "black hole.\nWe know we can change things by sqeezing them, coal into diamonds etc, but there are some materials such as water that are supposed to be incompressible.\nWhat we are supposed to think is the acceleration gradient is so massive that atoms are stripped into their components.\nThe thing is, if the graviation is so massive beyond the event horizon that things are moving at the speed of light.\nThis is a contradiction according to the relativistic E=MC^2 equation.\nIn order for something to travel at the speed of light it must have no mass.\nWe know light has no rest mass.. I.e. stop some light and you get energy but nothing to look at.\nTherefore we are supposed to assume that a massive body changes into pure energy to reach the speed of light and then turn back to mass when it gets to the centre of the black hole.\nThe conclusion there is neither mass nor energy according to the laws of physics currently at the centre of a black hole.

The mass of the sun is 330,000 times that of the earth. It is about half again as dense as water.
