This question already has an answer here:
Recently a paper in Nature about 2 black holes PG 1302-102 merging and causing a supernova 100 million times more powerful than common ones got me thinking.
How much damage do gravitational waves do and how close would someone have to be to the source for it to hurt them? or would you not feel a thing from it?
(The link given in comments does not answer whether a gravitational wave would do any damage or whether you would feel it. It does not cover how big a collision would have to be and how far away you would have to be to feel it. What you would feel and how the wave would interact with your body to cause the feeling. There is a +100 bounty still on the question so I assume it has not been answered)
