The Black Hole Myth: Even Galaxies Can Escape Them



"...the 'Schwarzschild singularities' do not exist in physical reality." -- Albert Einstein, mathematician, 1939

"Even mainstream scientists admit that at singularities the ‘laws of physics’ break down. It would be more accurate to say that their own theories break down." -- David Pratt, natural philosopher, 2005

Science Daily: Black Hole Caught Zapping Galaxy Into Existence?

black holes may be "building" their own host galaxy.

A Sea of Holes



The holes are in their logic. Stephen Smith: A Sea of Holes.

A recent announcement by scientists from the Max Planck Institute has added another wrinkle to the fabric of black hole physics, the ejection of a “supermassive” black hole from its parent galaxy. Researchers in the department of Extraterrestrial Physics measured what appear to be gravity waves from the so-called “ejection event”.

According to conventional cosmological theories, black holes are formed when a star with a mass approximately five times that of our sun uses up its thermonuclear fuel and collapses under the force of its own gravity. Because the equations that describe gravity can be manipulated in irrational ways, some solutions imply that such a large star can contract into a zero volume containing infinite inertial mass. Astrophysicists have contended for years that black holes are real and that their effects can be observed, although they are invisible to detection.

As the theories suggest, black holes possess a gravitational attraction of such intensity that not even electromagnetic radiation can escape the event horizon. Thus, no direct evidence of a black hole’s existence can be measured, only the hypothetical effects of the extreme gravity. Such effects are said to be gamma ray emissions, x-rays and extreme ultraviolet radiation [note that all the effects are electromagnetic] from the gases and dust as they are compressed into smaller and smaller spaces before being drawn down into oblivion.

According to the team from Max Planck, gravity waves of colossal magnitude spread out from Quasar SDSS J092712.65+294344.0 as it ejected a few hundred million solar masses of gravitational energy from its nucleus. Gravity waves are another theoretical construct with no observational evidence to confirm their existence. They are inferred by the detection of broad-spectrum emission lines from the hot gas that surrounds the black hole – an indication of gravity waves compacting the gas as they ripple through the region. But is that what is actually happening?

Plasma Jets = Black Hole?



Scientists have observed jets of electric plasma but they call it a black hole: Black hole outflows from Centaurus A detected with APEX.

Astronomers have a new insight into the active galaxy Centaurus A (NGC 5128), as the jets and lobes emanating from the central black hole have been imaged at submillimetre wavelengths for the first time. The new data, from the Atacama Pathfinder Experiment (APEX) telescope in Chile, which is operated by ESO, have been combined with visible and X-ray wavelengths to produce this striking new image.

Centaurus A is our nearest giant galaxy, at a distance of about 13 million light-years in the southern constellation of Centaurus. It is an elliptical galaxy, currently merging with a companion spiral galaxy, resulting in areas of intense star formation and making it one of the most spectacular objects in the sky. Centaurus A hosts a very active and highly luminous central region, caused by the presence of a supermassive black hole (see ESO 04/01), and is the source of strong radio and X-ray emission.
I hearby offer a million dollars to anyone who can see the black hole in this picture: Black Holes Light Up.

But what you won't see -- even with a telescope -- black holes! In fact, Miller doesn't even use one to study black holes. He uses his computer.
So much for observation and the scientific method.
