"On 8:41 am EDT August 17, 2017, LIGO detected a new gravitational wave source, dubbed GW170817 to mark its discovery date. Just two seconds later NASA's Fermi satellite detected a weak pulse of gamma rays from the same location of the sky." https://www.cfa.harvard.edu/news/2017-30

"Just two seconds later" and "the same location of the sky" implies that gravitational waves and gamma rays absurdly traveled hand in hand: same gravitationally deflected path; same speed; same Shapiro delay; where cosmic matter blocks gamma rays, it equally blocks gravitational waves too. Fraud, isn't it?
