American physicists say it is possible that they have accidentally discovered dark matter. According to a new hypothesis, the dark matter would actually be black holes surrounding galaxies that stretch as filaments throughout the whole intergalactic #Space. This was reported on Descopera.ro and iflscience.com.
The detected black holes would help to explain dark matter.
The physicists at John Hopkins University from Baltimore say the theory they have issued relies on the fact that the black holes detected by the system LIGO (Laser Interferometer Gravitational-Wave Observatory) have the exact masses needed to be space objects which would help explain dark matter. Marc Kamionkowski, one of the authors of this theory said they don't hold that these black holes are, in fact, dark matter. He said they have no confidence that this would be true and that it's just a plausible argument.
Detected last year.
In September last year, LIGO telescopes detected two black holes - with masses 30 times higher than the mass of the Sun - merging into a cosmic object with a mass about 60 times higher than the Sun. Normally black holes form from massive stars that don't have 15 times greater masses than the mass of the Sun. Therefore, the objects detected by the Laser Interferometer Gravitational-Wave Observatory could have been formed from stars with large dimensions, like the oldest celestial bodies discovered so far. The researchers from Baltimore also performed a series of numerical simulations. The experiments have revealed that the objects studied might very numerous.
The discovery of gravitational waves could be related to dark matter.
Marc Kamionkowski said that if "you notice events involving objects with masses 30 times bigger than the Sun, then you must provide an explanation. The discovery of gravitational waves could be related to dark matter. There is huge potential. " To be considered valid, the hypothesis formulated by US scientists must first be demonstrated and verified. If, indeed, the theory proves to be valid, it could be used to solve one of the biggest mysteries in astronomy - proving the existence of dark matter. #Science
