hole with the equivalent of 62 solar masses, blasting out 50 times more energy than all the stars in the universe combined.
@Vic: «but I can tell you that things like the Big Bang, the Multiverse, etc. are theories at best, and the Theory of General Relativity and Quantum Mechanics are in a direct
collision course when it comes to the Black
Holes, and Gravity is the show stopper
for a Unified Field Theory, and so on and so forth.»
Scouting out the locales where black
hole pairs live allows astronomers to look

collisions of neutron stars or black
holes that generate gravitational waves.
In a hopeful sign
for humankind, the U.S. National Science Foundation put up the money and two black
holes provided the
collision in 2015, as reported in February 2016 in Physical Review Letters and widely celebrated by bloggers.
Scientists led by Durham University's Institute
for Computational Cosmology ran the huge cosmological simulations that can be used to predict the rate at which gravitational waves caused by
collisions between the monster black
holes might be detected.
As each of these theories predicts different initial masses
for the seeds of supermassive black
hole seeds, the
collisions would produce different gravitational wave signals.
No
collisions have been observed directly, but astronomers have found several pairs of black
holes that are very close to each other, including some that are orbiting each other and some that seem to be on course
for a
collision.
And a spacecraft called Lisa Pathfinder launched last December to test technology
for a proposed space - based observatory that will be sensitive to longer - wavelength gravitational waves from supermassive black
hole collisions.
There have been heaps of excitement about the official launch today of the Large Hadron Collider — whether it's visions of protons flying around the world's largest particle accelerator and creaming one another, or
for some, the thought of those
collisions creating world - destroying black
holes.
Physicists will observe the
collisions not only
for clues to fundamental constituents of matter, hidden dimensions, and the elusive Higgs boson — the hypothetical particle that gives matter its heft — but also
for tiny black
holes winking in and out of existence.
Three projects — the Parkes Pulsar Timing Array in Australia, NANOGrav in North America and the European Pulsar Timing Array in Europe — are monitoring dozens of pulsars
for tempo changes that can reveal not only single
collisions but the cacophony of gargantuan black
holes smashing together throughout the universe.
For example, the waves detected by the Laser Interferometer Gravitational - Wave Observatory (LIGO) operated by Caltech and Massachusetts Institute of Technology came from the
collision and merging of two major black
holes 1.3 billion years ago.
So far, only the gravitational waves from black
hole mergers have been detected, but as the sensitivity of laser interferometers increases, scientists hope to detect
collisions between neutron stars,
for example.
Researchers have «dissected» the mysterious gases oozing from two supermassive black
holes on the verge of
collision in galaxy NGC 6240
for the first time.
«Theoretically a consequence of violent cosmic events — the
collisions of black
holes, the explosive deaths of stars, or even the big bang — gravitational waves could provide a brand new lens
for studying the universe,» writes Science magazine.
