Sorry, this just doesn't work. You're using other people's guesses off what happens in black holes. Some things are known about them, but other things are just guesses. To say matter is just simply condensed into a singularity the size of a needle point is a guess.
Also, please give your evidence/dating method for ages of black holes? Your evidence for only 1% consumption?
Uh, yes, it does work, whether you like it or not. Truth doesn't depend on whether people want to accept it. It just is. A theory is a lot different than a guess, btw. Theories are backed by credible scientific evidence. Theory does not equal guess. You just proved how much you know about science by saying that. If you actually GO BACK AND READ MY POSTS ABOUT BLACK HOLES you'd see the methods scientists use to determine the age of black holes, how they form, what they consume, where this matter goes, what happens to the matter, and how much of the matter they consume. It's all in the posts. Black holes shoot out most matter that they stretch apart and destroy.
"Bad manners
Black holes are known to be sloppy eaters. They digest only a small amount of what's on their dinner plates, spitting the rest back into space. In this case, only about 1 percent of the star was ultimately swallowed, the research team concluded. The rest of the star's gas was flung into the galaxy by the momentum and energy of the whole interaction, including by the radiation kicked up by the portion of gas that did disappear.
The latest observations were made with NASA's Chandra X-ray Observatory and the European Space Agency's XMM-Newton when the flare had settled down considerably. The research team had first examined earlier images made by the German Roentgen satellite (ROSAT) from 1990 and 1992, which showed the flare at its brightest.
The flare's intensity decreased by about 200 since then. That is consistent with a star being torn apart to feed the black hole, Komossa explained, as opposed to a smoother flow that would have occurred if the black hole were consuming a giant gas blob of similar mass.
This decline of activity over time also suggests the flare was not part of normal, prolonged feeding activity that occurs around other supermassive black holes called quasars.
At the height of the flare, the black hole swallowed the equivalent of one Earth every 10 minutes.
Similar flares have been observed in other galaxies. But none had been recorded in such detail, the researchers said.
Black holes can't be seen, because once matter or light is trapped in one, it cannot escape. Astronomers infer the existence of black holes by noting flare activity around them and also by measuring the speed with which nearby stars and gas orbit. Just before disappearing into a black hole, material is accelerated to nearly light-speed.
Chandra showed that the outburst came from the center of the galaxy, where the suspected black hole sits. The XMM-Newton observations revealed other fingerprints of a black hole, ruling out other physical explanations for the flare-up, the scientists said.
"I think this is very strong evidence that stars are being ripped apart occasionally by supermassive black holes," said Alex Filippenko, a professor at the University of California, Berkeley who was not involved in the work.
Similar observations in other galaxies would help theorists gain a better understanding of how black holes work and the important role they play in galaxy formation. Filippenko said scientists could now begin to set constraints on how frequently these stellar destructions actually occur and study how black holes grow and evolve with time."
