A Hundred and Forty Two Solar Mass Black Hole

We can use this as a way to weigh black holes that we cannot otherwise directly see. gravitational waves can pass through anything, and no amount of gas or dust or radiation or whatever stop them. We're planning to build future crazy gravitation observatories that might be able to see even bigger ones from further away. In space, i know it seems bonker is right that you could have tike two satellites and have them maintain an exact distance relative to each other. But if they build it, lisa will be very powerful at seeing gravitational waves, and ou could detect them from intermediate mass black hole murders.
