    This is becoming so routine there's no fanfare anymore.

    Agreed....It reminds me of the Apollo missions. Interest was already lost After Apollo 11, and it took a near fatality with Apollo 13 to wake people up.
    I noticed your last thread re the last GW discovery via colliding Neutron stars did not even raise a hackle [other then myself] from members here, yet in actual fact, there was more to learn from that discovery then the so far 5 BH binary collisions.
    Thanks again sweetpea!

    Remember, there use to be someone here that said nothing ever reaches the event horizon... if that were true, the black holes in these detected mergers would still be circling each other and still be 'emitting' gravitational waves. I wonder how that person would explain the big spike and ringdown part of the signal?

    I remember at least three of them.
