会膨胀的

And the expanding universe will continue - perhaps for ever - becoming ever colder, ever emptier.

宇宙将继续——也许会永远——越变越冷、越变越空。

Ambitious future observers might also send out probes that escape the supergalaxy and could serve as reference points for detecting a possible cosmic expansion.

有企图心测者，或许会发射一些能够脱离级星系探测器，做为侦测宇宙参考点。
