@not4u2no3 @BenMonroe1 @BruceyXRP @konstructivizm The Hubble telescope wouldn't be any less USG than the lunar observer anyway. But like I said elsewhere, you can bounce a laser off the retroreflectors left there. Those aren't natural phenomena.
@not4u2no3@BenMonroe1@BruceyXRP@konstructivizm无论如何，哈勃望远镜的USG不会低于月球观测者。但正如我在其他地方所说，你可以将激光从留在那里的后向反射器上反射回来。这些不是自然现象。
