Isn't it also that power decreases over the cube of the distance to the event? A truly gargantuan amount of power (1 solar mass equivalent) distributed across a 3-dimensional shell dozens or hundreds of light years across should be minuscule at any Earth-sized point along that shell.
- tehmaco 10y agoThey put the distance at 440−190+180 Mpc. 440 megaparsecs is is around 1.2 billion light years away(!).
- elihu 10y agoWouldn't it be inverse square, not inverse cubed? Or do gravity waves behave different than other things we're used to, like light?
- dsqrt 10y agoActually the nice thing about gravitational waves is that we are sensitive to their amplitude, which scales as 1/r, and not to their energy, which scales as 1/r^2.
