Black holes are not just standing still all the time

Many people imagine black holes as certain huge areas that just sit in space not doing nothing but this really isn't the case. In fact, according to the latest research coming from the scientists at Brigham Young University black holes are in fact very active, not only do they spin but they also move laterally across their host galaxy. These movements are believed to power quasars.

Quasars are among the brightest persistent lights in the universe and this was the first study to suggest the connection between black holes and quasar's light. Quasars usually inhabit the very centers of active young galaxies and can emit up to a thousand times the energy output of the Milky Way.

According to the professor David Neilsen, lead author of the study, "The black hole is like a generator spinning around in these magnetic fields and the way the field lines get twisted around and pulled by the spinning black hole creates electromagnetic tension that gets turned into radiation and energy that goes out".

If this latest theory is true then the biggest and brightest quasars have origin from black holes that both spin fast and traverse their host galaxy at high speeds.

The scientists also believe that these two movements do not compete with each other, in fact they do the opposite as they combine each other to give the overall energy that seems to be streaming away from the black hole.

The more detailed info about this study could be found in the current issue of Proceedings of the National Academy of Sciences.
