heres the paper. Anything is detectable if the adversary has the original. This technique claims to result in files that are statistically indistinguishable from unaltered files of the same type. E.g. you can't build a filter to examine all the videocalls going over a wire and find the one carrying stenography.

I did the math a while back- you have to be crazy close, like 100s of km, to a merger for the gravity waves to affect you directly. /u/StandardSudden1283 Even a 'cold' pair of BHs (no accretion disk) would kill you from tidal forces at a much greater distance.

The article/u/kanrith links to suggests the waves could cause earthquakes or something on the planet you're on, and so indirectly hurt you, but its not verry convincing.
