Black hole blowback
Article Abstract:
Astronomers have used a combination of radio and x-ray telescopes to discover vast bubbles of high-energy particles hundreds of thousands of light years across, which is believed to be created by black hole. The gases in the narrow jet creates bubbles, add heat and magnetism to the intergalactic gas in a galaxy cluster and this process might be a part of multimillion-year cycle that regulates the growth of supergiant galaxies in the centers of clusters.

An echo of Black holes
Article Abstract:
Black holes are a testing ground for quantum gravity as there are few places where quantum mechanics and general relativity are both critically important. The horizon of a black hole is the surface that separates the inside of a black hole where the gravity is so strong nothing can escape.

THE SEARCH FOR RELATIVITY VIOLATIONS: to uncover evidence for an ultimate theory, scientists are looking for infractions of Einstein's once sacrosanct physical principle
Article Abstract:
Theories that unify gravity, quantum mechanics, and other forces of nature can predict small violations of special relativity. Lorentz symmetry and loop quantum gravity are examined.
