JUST IN: Study Shows Black Holes Directed by Magnetic Fields

This new finding furthers ECMs new equation identifying a connection between our galaxy Milky Way, channeling charged particles in a narrow bands which would have a significant effect on our Sun, all planets in our solar system, and all that lives on them.

New Equation:

Increase Charged Particles -->Decreased Magnetic Field -->Increase Outer Core Convection -->Increase of Mantle Plumes -->Increase in Earthquake & Volcanoes -->Cools Mantle and Outer Core -->Return of Outer Core Convection (Mitch Battros - July 2012)

Once again, a feeling of accomplishment and free-floating-anxiety simultaneously engulf all my senses. Not necessarily a pleasant feeling - sometimes reflecting intense mood-swings. Why? Probably because of venturing into the unknown - or is it 'the known' - or maybe it's both at the same time.

Personal note: Remember, prophecy or prediction does not produce a regimented fate. In fact, the purpose of prophecy is to alter the outcome by empowering us with knowledge. But there is a catch. We have to make will thought-out choices and changes using our gift of discernment and for some of us, our 'learned' skill of critical thinking.

Advancing black holes produce intense radiation and powerful relativistic jets, which are affected by the black-hole's spin magnitude and direction. While thin disks might align with the black-hole spin axis via the Bardeen-Petterson effect, this does not apply to jet systems with thick disks.

A newly published study describes how astrophysicists used simulations, which follow both the rules of general relativity and the laws of magnetism, to demonstrate that gravity isn't the sole arbiter of a spinning black hole's behavior.

Dr. Jonathan McKinney, professor of physics at the University of Maryland describes his team's findings: "We used fully three-dimensional general relativistic magneto-hydrodynamic simulations to study accreting black-holes with various black-hole spin vectors and disk thicknesses with magnetic flux reaching saturation. Our simulations reveal a "magneto-spin alignment" mechanism that causes magnetized disks and jets to align with the black-hole spin near black-holes and further away to reorient with the outer disk."

This mechanism has implications for the evolving of black-holes such as the one in our galaxy Milky Way and our neighbors Andromeda, SgrA* and M87.

 


Near the black hole, spiraling magnetic fields cause the material in the accretion disk to orbit about the black hole in the same direction as the black hole's spin. Twisting lines of magnetic force launch two jets of particles in opposite directions at close to the speed of light. These jets, called relativistic jets, initially speed away parallel to the black hole's axis of rotation - its north and south poles. But as gravity's grip weakens, the charged gas in the outermost regions of the accretion disk pulls at the jets, pulling them away from the black hole's rotational axis even as the jets collide with that gas and knock it away from the black hole.

McKinney says the results of the simulations have direct consequences for studies of the delicate balance between how much gas a black hole can pull in from its accretion disk and how much gas it blows away with its jets. The greedier the black hole, the more gas it pulls in and the more energy is funneled to the jets, until they become so powerful they can blast the surrounding area clear - shutting down star formation in the vicinity - and, says McKinney, "The black hole stops its own growth."

According to their simulations, the boost in energy provided by all the forces interacting around a black hole, including the magnetic force, makes a black hole even better at blasting its surroundings clear than currently thought. "Based on our study we're saying there are some aspects of the feedback mechanism that we don't understand," McKinney said, and this remains a major unsolved problem in astrophysics.

Soon, though, the work of McKinney and his colleagues, Alexander Tchekhovskoy of Princeton and Roger Blandford, director of the Kavli Institute for Particle Astrophysics and Cosmology at SLAC and Stanford, may be confirmed by actual observation. A globe-spanning array of telescopes all acting as one called the Event Horizon Telescope has been making its first close-up observations of black holes - with some help, said McKinney, from their simulations. "Any interpretations are still very preliminary," he added, but the possibility that their ideas soon might face a direct test is exciting.
