mindboggling

Hard to fathom

Mindboggling describes something so extraordinary, complex, or vast that the mind struggles to comprehend it: The mindboggling scale of the universe, mindboggling amounts of data.

The image is of a mind that boggles—hesitates, recoils—when confronted with something beyond easy grasp.
