alt Hacker News> a cubic kilometer of ice into a neutrino detector. How? Scientists drilled boreholes 2.5km deep into the ice
Seems odd that boring 2.5km into ice would protrude 1.5km out the other side of a cubic km.

The upper layers of detectors are buried over a kilometer below the surface in order to shield the array from most cosmic rays.

If they drilled down any further they'd reach the interior of the hollow earth, obviously not permitted

A cubic kilometer is a volume, it does not dictate the shape.
