会膨胀的

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

膨胀的宇宙将继续——也许会永远——越变越冷、越变越。

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

有图心的未来观测者，或许会发射一些能够脱离级星系的探测器，做为侦测宇宙膨胀的参考点。
