Swimming on the Moon

Humankind was just given our most recent reminder that we really don't know anything.

A "significant amount" of frozen water has been found on the moon, the US space agency said Friday heralding a major leap forward in space exploration and boosting hopes of a permanent lunar base.

Preliminary data from a moon probe "indicates the mission successfully uncovered water in a permanently shadowed lunar crater," NASA said in a statement.

"The discovery opens a new chapter in our understanding of the moon," it added, as ecstatic scientists celebrated the landmark discovery.

If only it had been cheese that they had found.
