CalTech Scientists have heard a baby black hole for the very first time, and the sounds it makes is just like a chirp. Physicists from the Massachusetts Institute of Technology have found more proof that Albert Einsteins theory of general relativity is corr…

Cast your mind back four years, and gravitational waves were the talk of the town. On September 14, 2015, the first detection of these ripples in space-time was made by the LIGO-Virgo collaboration, revealed months later to deserved global fanfare. Now with t…

In its first major result, just over a year after its inauguration, a super-sensitive South African telescope has discovered two giant ‘radio bubbles’ above and below the central region of the Milky Way. The features stretch over a total of 430 parsecs (1,400…

Two University of Hawaii at Manoa researchers have identified and corrected a subtle error that was made when applying Einstein's equations to model the growth of the universe.Physicists usually assume that a cosmologically large system, such as the universe,…

(CNN)  NASA scientists spotted pops of blue and green X-rays in a distant galaxy. What caused them to shine, exactly, is mystifying scientists. The bright rays belong to ULX-4, short for the fourth ultraluminous X-ray source found in the Fireworks Galaxy, ab…

Now grab a thermodynamics textbook, locate the laws, and see if you can find true statements when you replace the thermodynamic terms with black hole variables. In many cases you can, and the analogy improves. Hawking then discovers Hawking radiation, which …
