Did the Earth move for you, too? Grav waves sensed from black holes' bang 1.8bn LYs away

Re: A three-sun tidal wave!

I wonder how near you'd have to be to personally experience the tug.

When the detection as announced last year I worked out what the displacement would be from a light year away. I forget the exact result now, but I think it was on the order of a metre. The problem is, how would you experience that? It's a contraction and expansion of space and time, propagating at the speed of light. Would you even be able to detect that with your human senses? Would the tidal force instantaneously tear apart all matter larger than an atom? I'm having trouble thinking that one through.
