New study proves Hawking was right, black holes only get bigger

In a study published on Monday, scientists from Massachusetts Institute of Technology (MIT) and Cornell University their findings from a research project which analyzed ripples in spacetime created by two black holes that spiraled inward and eventually merged into one bigger black hole. The ripples studied were the first gravitational waves ever identified, detected by the Advanced Laser Interferometer Gravitational-Wave Observatory in 2015. Splitting the gravitational wave data into time segments before and after the black holes merged, the researchers calculated the surface areas of the black holes in both periods. The physicists found that the surface area of the new black hole was actually greater than the two initial black holes combined. The finding confirms a prediction made by famed scientist, Stephen Hawking, in the 1970s, in which he stated that black holes cannot decrease in surface area as it mirrored a rule in physics, that entropy or disorder can’t decrease over time.........Read more
