GW170104: Observation of a 50-Solar-Mass Binary Black Hole Coalescence at Redshift 0.2<\/strong><\/h4>\n

We describe the observation of GW170104, a gravitational-wave signal produced by the coalescence of a pair of stellar-mass black holes. The signal was measured on January 4, 2017 at 10?11:58.6 UTC by the twin advanced detectors of the Laser Interferometer Gravitational-Wave Observatory during their second observing run, with a network signal-to-noise ratio of 13 and a false alarm rate less than 1 in 70?000 years…<\/p>\n

Assuming that gravitons are dispersed in vacuum like massive particles, we bound the graviton mass to\u00a0mg?7.7\u00d710?23??eV\/c2. In all cases, we find that GW170104 is consistent with general relativity.<\/p>\n

“It looks like Einstein was right\u2014even for this new event, which is about two times farther away than our first detection,” says Laura Cadonati<\/a><\/strong> of Georgia Tech and the Deputy Spokesperson of the LSC. “We can see no deviation from the predictions of general relativity, and this greater distance helps us to make that statement with more confidence.”<\/p>\n

Chiudiamo ricordando gli errori fatti nell’illusione di avere capito fenomeni lungi dall’essere stati scientificamente risolti e prendendo provvedimenti sbagliati.I pi\u00f9 famosi errori fatti sono quelli del Ddt [1] e del buco dell’ozono.\u00a0La proibizione del Ddt [2] port\u00f2 a un milione di morti all’anno per malaria. Il buco dell’ozono non era di natura dinamica ma chimica [3]: una sola molecola di Cfc [4] distrugge 100mila molecole [5] d’ozono.<\/p>\n
