Abstract: We discuss how pressure affects the matter–matter gravitational interaction. We show the frequently used claim that gravitation is produced in General Relativity not only by the mass density $\rho$ but also by the pressure $\rho$ in the combination $\rho + 3p/c{^2}$ to be incorrect. The way pressure actually influences gravitation is discussed together with some related problems.

Keywords: Einstein's general theory of relativity, antigravitation.
