Men of science believe that in millions of years the
earth will lose the shape of a globe and become a sort of pyramid or
tetrahedron. The earth was formed as a round globe. In cooling down the
Poles were flattened and its surface was fixed. But the core is still
cooling and shrinking, and the hard unshrinking surface must adjust
itself to a smaller bulk. The shape of a globe is the shape that gives
the biggest possible surface for its size; but there is another shape
that gives the smallest possible surface for its size, and the earth
seems likely to assume this shape. It is a sort of pyramid shape, and
is called a tetrahedron.
