Dark energy causes the acceleration by pushing space itself apart, altering the distances to the supernovas as it does so.
暗能通过推进空间分离而加速，因此就像所观察到的那样加大了距离。

Any missions hoping to go farther will need a means of acceleration that can get the spacecraft to the edge of explored space faster—before it has depleted its radioactive power source.
故而，任何更深空的宇宙探索都需要寻找技术途径来加速航天器，以便在放射性能源耗尽之前到达星系边缘。

As the mobile device moves, a built-in accelerometer reports linear acceleration changes along the three primary axes in three-dimensional space.
