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.

有企图心的未来观者，发射一些能够脱离级星系的探器，做宇宙膨胀的参考点。
