Scientists discover that some black holes have standard masses and emit universal sounds when they merge, revealing new insights into stellar evolution and cosmology.
The frequency of the gravitational waves increases as the black holes spiral closer together, creating a characteristic chirp signal that can be measured on Earth. By analyzing this signal, scientists can determine the chirp mass, a combination of the two individual black hole masses.

However, the HITS team’s models suggest that there are some standard black hole masses that result in universal chirp masses. “The existence of universal chirp masses not only tells us how black holes form”, says Fabian Schneider, who led the study at HITS, “it can also be used to infer which stars explode in supernovae.” This could help solve some of the mysteries surrounding the supernova mechanism, the nuclear and stellar physics involved, and the accelerated expansion of the Universe.
