  Assuming the existence of a Multidirectional Homogeneous and Constant Shower
of Elementary Particles (MHCSEP) traveling at light speed in space, several
basic laws of physics are derived mainly by geometrical considerations. When
placing two bodies in space, obstruction of the MHCSEP creates an attractive
force among them that coincides, for two bodies, with Newton's law of gravity,
generating a mechanical explanation for gravity.
