This paper addresses questions concerning how pressure affects the matter-matter gravitational interaction. It invalidates the often-used claim that in the general theory of relativity gravitation is produced not only by the mass density ρ but also by the pressure p through the combination ρ + 3p/c2. The way pressure actually influences gravitations is discussed together with some related problems.
