Simply stated, when buildings collapse, the weight of the ceilings
falling upon the objects or furniture inside crushes these objects, leaving a
space or void next to them. This space is what I call the 'triangle of life'.
The larger the object, the stronger, the less it will compact. The less the
object compacts, the larger the void, the greater the probability that
the person who is using this void for safety will not be injured. The next
time you watch collapsed buildings, on television, count the 'triangles' you
see formed. They are everywhere. It is the most common shape, you will see,
in a collapsed building.
