Among all observable objects of the universe, the sources of Gamma-ray bursts (GRBs) are those physical bodies which are observed with the smallest angular sizes. Their specific physical properties can be pointed out, provided there is some physical limit for the smallest angle between the different world lines of photons. A new physical assumption is proposed, viz., that the smallest angle exists, and that its value is estimated as the ratio (le)/(lp) between the elementary electromagnetic length le = (e2)/(4)(pi)(epsilon0)(m)(c2) = 3 x 10-13 cm and the Planck quantum length lp = ((Gh)/(c3))1/2 = 1.6 x 10-33 cm. This assumption is shown to lead directly to the concept of the discrete geometry of the space, i.e., to the concept of a geometry with a finite number of different directions. Analysis of the observations of GRBs could easily prove or disprove this assumption, and appropriate observational tests are proposed below for its verification.
