[ExI] Advanced LIGO

[John Clark]

LIGO should get back online and start detecting gravitational waves again
in about a month after being upgraded, and now they're talking about the
upgrades that will come after that. By 2022 they expect to be able to
detect one Black Hole merger a month and by 2025 one per hour. The quality
of the observations will go up too, they'll be able to tell how fast the
holes were spinning even before they merged.

LIGO to spot one black-hole merger per hour
