Previous studies have been made of OJ 287 that have accounted for gravitational waves, but the 2018 model is the most detailed to date. By factoring information gained by LIGO since 2015 into this model, the team was able to narrow the window in which a flare is expected to just 1.5 days. To further refine their predictions, they also included details about the larger black hole’s physical characteristics.
Specifically, the new model incorporates the “no-hair” theorem of black holes, a theory originally proposed in the 1960s by a team of physicists that included Stephen Hawking. This theorem predicts that the “surface” of a black hole – or rather, their outer boundary (aka. event horizon) – is entirely symmetrical along its rotational axis. This further narrowed the team’s predictive model to just a few hours.
By predicting the smaller black hole’s orbit with this level of precision, the new model supports the no-hair theorem.
In short, the OJ 287 system supports the idea that black hole surfaces are symmetrical along their rotational axes. “It is important to black hole scientists that we prove or disprove the no-hair theorem,” said Mauri Valtonen, an astrophysicist from the University of Turku and a coauthor on the paper. “Without it, we cannot trust that black holes as envisaged by Hawking and others exist at all.”
IMHO, there cannot be such objects as singularities (0 size & infinite density) in the real universe!
Everything should/must be made of particles (including black holes)!
& if black holes should/must be made of particles, then there is only 1 realistic possibility: Planck particle!
Existence is eternal. We are here, surrounded by matter and order because no process has ever destroyed it. Including black holes in previous big bang contents. Order even survived coming through our Big Bang. Order can't be created or destroyed. This all goes to show that one day all that went into black holes will come out again, both matter and order.Hair may record the information swallowed by the gravitational monsters.
