它可以产生与万有引力相反的斥力，产生大爆炸中的暴涨，随后使宇宙产生更为平稳的加速度，这种加速度归因为暗能量。
It can produce repulsive gravity to drive cosmic inflation in the big bang, while later on it could generate the more sedate acceleration that is ascribed to dark energy.
这个速度理论上与黑洞的引力作用直接相关。
The motions are directly related to the gravitational pull of the black hole.
而冥王星的距离，是水星的一百倍，那么它的引力与向心加速度，均是水星的一万分之一。
So if you are 100 times further away like Pluto compared to Mercury then the gravitational... the centripetal acceleration which is due to gravity is 10,000 times smaller.
