Catching
more black hole collisions will also help map out their distribution in the universe, which is nearly impossible to do any other way.
Since that first detection, scientists have observed three
more black hole collisions.
As
more black hole collisions are found, researchers hope to piece together how and where these destructive duos form.
Not exact matches
For comparison, the
collision detected in September created a
black hole with the equivalent of 62 solar masses, blasting out 50 times
more energy than all the stars in the universe combined.
Rainer Weiss, a German - born American physicist, of the Massachusetts Institute of Technology in Cambridge, took a defining step when he authored a 1972 paper on the design of a laser - based interferometer to detect the
collision of
black holes in outer space that would take
more than a billion years to reach Earth.
And as LIGO continues to detect
more collisions, the data about
black holes will keep piling up.
LIGO's breakthrough discovery offers up new ways to test relativity,
black hole collisions, dark energy, the first stars in the universe, and
more
UCI's celestial census began
more than a year and a half ago, shortly after the news that the Laser Interferometer Gravitational - Wave Observatory, or LIGO, had detected ripples in the space - time continuum created by the distant
collision of two
black holes, each the size of 30 suns.
Light from the
collision should help test Einstein's theory of general relativity, and tell us
more about two huge bubbles of hot gas at the centre of the Milky Way that the
black hole may have spawned.
Collisions between very energetic particles would then be much
more likely than a 3 - D analysis would predict, and the creation of microscopic
black holes could be within reach of the latest technology.
Comparison with the SXS simulations revealed that the signal was from the
collision of two hefty
black holes 29 and 36 times
more massive than the sun and located 1.3 billion light - years from Earth.
But if all goes well, the team even has a prediction of where the
collision is most likely to take place: In a neighborhood like the Sombrero Galaxy, where a slightly less massive supermassive
black hole means the
collision would happen
more slowly, leaving scientists
more time to spot its signature.
When a
black hole is created from a supernova from a massive star or a
collision between neutron stars (or a neutron star with a
black hole), one of a pair of bi-polar jets of gamma rays travelling at near light - speed may be directed at the Earth (
more).
In 2005, astronomers announced that GRB 050709 and GRB 050509B may be have created by
collisions involving two neutron stars (
more from Chandra X-Ray Observatory) and ESO), but that the presence of a second flare by GRB 050724 was
more likely to have been produced by a neutron star's merger with a
black hole (ESO).
