The star field behind the black holes is being heavily distorted and appears to rotate and move, due to extreme gravitational lensing, as space-time itself is distorted and dragged around by the rotating black holes. [1] A binary black hole (BBH), or black hole binary, is a system consisting of two black holes in close
Staind also uses this tuning (but with the 2nd string tuned up 1/2 step to emulate a 7-string guitar), as well as several other modified variations of this, such as one in which the 5th string is also dropped from D# to C#. Periphery also uses this tuning on a 7-string guitar frequently (G#-D#-g#-C#-F#-A#-D#). Drop G – G-D-g-C-E-A
Gaia BH2 (Gaia DR3 5870569352746779008) is a binary system consisting of a red giant and what is very likely a stellar-mass black hole.Gaia BH2 is located about 3,800 light years away (1.16 kpc away) in the constellation of Centaurus, making it as of 2024 the third-closest known black hole system to Earth.
Known gravitational wave events come from the merger of two black holes (BH), two neutron stars (NS), or a black hole and a neutron star (BHNS). [ 9 ] [ 10 ] Some objects are in the mass gap between the largest predicted neutron star masses ( Tolman–Oppenheimer–Volkoff limit ) and the smallest known black holes.

The initial model estimates the mass of the primary black hole to be approximately 18.35 billion solar masses and the secondary black hole around 150 million solar masses. More recent models estimate that the central supermassive black hole has a mass of 100 million solar masses, [ 6 ] much less than previous estimations.
The black hole's mass is 32.70 M ☉, the heaviest known stellar black hole in the Milky Way. The black hole Gaia BH3 is the second known stellar black hole more massive than about 10 M ☉ (with the first being Cygnus X-1). [2] The mass of Gaia BH3 is quite similar to the mass of merging binary black holes found via gravitational waves.
The star and black hole orbit each other with a period of 185.59 days and an eccentricity of 0.45. The star is similar to the Sun , with about 0.93 M ☉ and 0.99 R ☉ , and a temperature of about 5,850 K (5,580 °C ; 10,070 °F ), while the black hole has a mass of about 9.62 M ☉ . [ 3 ]
