文摘The nature of gravitation and <em>G</em> is not well understood. A new gravitation mechanism is proposed that explains the origin and essence of the gravitational constant, <em>G</em>. Based on general relativity, the vacuum is considered to be a superfluid with measurable density. Rotating bodies drag vacuum and create a vortex with gradient pressure. The drag force of vacuum fluid flow in the arm of the vortex is calculated relative to the static vacuum and a value that is numerically equal to that of <em>G</em> is obtained. Using Archimedes’ principle, it is determined that <em>G</em> is the volume of vacuum displaced by a force equivalent to its weight which is equal to the drag force of the vacuum. It is concluded that the gravitational constant <em>G</em> expresses the force needed to displace a cubic metre of vacuum that weighs one kg in one second. Therefore, <em>G</em> is not a fundamental physical constant but rather is an expression of the resistance encountered by the gravitational force in the vacuum.
