Our reading
An editorial interpretation.
The speaker reports that scanners show nothing, but describes the absence with a word suggesting abundance. That contradiction supplies the joke. Elaborate language briefly promises a rich discovery, only to deliver emptiness, making the disappointing result sound comically plentiful instead.
