I asked why a bomb going off on one side of a mountain would seemingly affect gravity for people on the other side of the mountain about a year ago. Experienced in Nam with valley floors about 2 miles apart. That's alot of rock and soil seperating those who experienced this from the explosion. Since that time I have learned that Nazi"s used a gravity weapon that produced a powerful sound and shock wave during World War 2. I'm asking again because I don't think you took me seriously the first time. No kidding, things would float on tables after a large explosion long before we would hear the blast. What exactly was affecting gravity?
