Hmm, so the gamma ray burst detection from Fermi just 0.4sec after the LIGO detection was coincidence? Unexpected and expected at the same time!

huh, considering we recently officially discovered gravity waves from two black holes fusing, this is interesting.
Nakito Koyuarto Exactly. They looked at the recorded data from the INTEGRAL satellite at the moment that LIGO detected the gravity waves, and INTEGRAL saw nothing. That non-observation is what’s significant: the theory says that we would see nothing, and that’s what made the Fermi satellite’s tentative detection so surprising.
interesting and what a new discovery wow!
Chris Dolan That’s got me wondering, what if it was because Earth’s gravity is interfering with Integral’s system…..
Nakito Koyuarto That theory doesn’t make sense to me. INTEGRAL is a gamma ray observatory. How could Earth’s gravity prevent detection of gamma rays by the satellite?
Chris Dolan Well, some denser objects are more affected by gravity. Materials and objects in INTEGRAL aren’t all the same density. This means that something may have shifted out of place. slightly.
