Alternatively, for an armchair, try Homebase or Ikea...

More seriously, how deep can this technology "see," and how big would the void have to be?

A scientific breakthrough in a Ministry of Defence research project could pave the way for a scanners that one day could see underground or through walls.

There's probably some tech out there that already claims that one day, it could lead to the possibility of there may be a small chance of something that might provide  the key to unlocking time travel.

I wouldn't get your hopes up.

Using gravity to make geological surveys is nothing new; this is just aiming to be a little more sensitive :) one of my favourite facts is that if you do careful scanning of sea level height from satellites, you can see the mid-ocean ridges where the sea level is higher because there is less gravity there (or something like that)...
