【摘要】 本研究试图表明,如将与宇宙常数有关的真空能考虑在内,就可利用牛顿力学的数学框架,将引力相互作用分为三个类型和两种表现如下:物质对物质——吸引,物质对真空——排斥,真空对真空——排斥。据此,得出了鉴别天体系统是处于膨胀状态还是处于收缩状态的一个判据。然后讨论了引力相互作用的三个类型和两种表现在总星系泡沫结构形成中的作用,认为真空能量(暗能量)扮演了起泡剂的角色。最后导出了空洞膨胀动力学方程,并对一空洞的膨胀加速度和速度进行了估计。更多还原

【Abstract】 This paper tries to indicate that if taking into consideration of the vacuum energy concerned with the cosmological constant,the gravitational interaction can be classified into three types and two performances by the use of the mathematic framework of Newtonian mechanics,i.e.matter to matter — attraction,matter to vacuum — repulsion,vacuum to vacuum — repulsion.Based on it,a criterion will be identified if the celestial system is found in an expansion state or in a contraction state.After the contribution discussion of three types and two performances of the gravitational interaction to evolution of the metagalactic foam structure,the vacuum energy(dark energy)is considered to play the role of the foamer.The dynamics equations of the void expansion will be deduced,and the void expansion acceleration and velocity can be estimated.更多还原
