"ËœDavid and Goliath' scenario explores extreme mass ratios (Goliath wins) Scientists have simulated, for the first time, the merger of two black holes of vastly different sizes, with one mass 100 times larger than the other. This extreme mass ratio of 100:1 breaks a barrier in the fields of numerical relativity and gravitational wave astronomy. Until now, the problem of simulating the merger of binary black holes with extreme size differences had remained an unexplored region of...

The same team of astrophysicists that cracked the computer code simulating two black holes crashing and merging together has now, for the first time, caused a three-black-hole collision.Manuela Campanelli, Carlos Lousto and Yosef Zlochower"”scientists in Rochester Institute of Technology's Center for Computational Relativity and Gravitation"”simulated triplet black holes to test their breakthrough method that, in 2005, merged two of these large mass objects on a supercomputer...

NASA scientists have reached a breakthrough in computer modeling that allows them to simulate what gravitational waves from merging black holes look like. The three-dimensional simulations, the largest astrophysical calculations ever performed on a NASA supercomputer, provide the foundation to explore the universe in an entirely new way. According to Einstein's math, when two massive black holes merge, all of space jiggles like a bowl of Jell-O as gravitational waves race out from the...

  • A landsman who is making his first voyage at sea; a novice who enters naval service from rural life.
According to the OED, a grass-comber is also 'a sailor's term for one who has been a farm-labourer.'
