Heaviest Black Hole Merger Ever

Scientists have observed the heaviest black hole merger ever found. On May 21, 2019, three telescopes on Earth received powerful gravitational waves far away from the depths of space. The signal coming from the event known as GW190521 lasted just one-tenth of a second. It turns out they have witnessed what may be the most massive black hole merger ever.

"that scientists thought was impossible"... Most exciting line. The Cosmos always manages to stretch beyond our expectations and suprise us everytime. We are always reminded how little we know.

[laneeret]

the universe has existed for roughly 14 billion years, he said the merger happened 10 billion years ago, but goes onto saying it was roughly 7 billion years old when it happened?

one of the black holes could have been created from a star collapsing? yet you said nothing is left behind with the pair instability?

Parsing frequencies...doing that is always a pleasure...
