Space matter is filled everywhere in the universe. All matter in the universe (in the ordinary world) is made of space matter. Since the gravitational force is exerted on space matter, a denser space matter surrounds all massive bodies. Bending of light when it passes through near massive object like a star, lensing effects in some regions in the galaxies are because of the refraction of light by the denser space matter that present in these regions and are purely the demonstrations for the presence of space matter in the macro world. Increasing of mass of a fast moving body, change in shape of a body resulting from its motion; the effect, known as the Lorentz-FitzGerald contraction etc are also the evidence for space matter in space. Also, electric field lines and magnetic field lines are created by the alignment of space matter units. All form of energy (except gravitational potential energy) are released because of the explosion, expansion or releasing of space matter. The releasing of energy in a nuclear reaction is due to the rapid-huge increasing of volume of ordinary matter to space matter. The missing mass (mass defect) in a nuclear or chemical reaction is converted into space matter. Since the ordinary matter is an extremely compressed state of space matter, when it released, they will explode violently and release energy. In this article, author explains a method for detecting the space matter that released in an exothermic chemical reaction.
