How do they know it’s black holes colliding and not just large stars?
- skulk 5y agoMaybe electromagnetic signals can disambiguate the two phenomena?
- foo92691 5y agoExtensive computer modeling is used to predict the expected waveforms, and then we fit the observed waveforms to the expected ones.

- still_grokking 5y agoIsn't it more like you fit actually noise to expected forms, and out comes the expected form? At least someone explained it like this to me.
