Cool advancements and invention.

Just like lidar was able to see through the trees of Mexico and find
lost cities, this will be able to do the same looking \"through\" the
terra firma.

Nice science, but the article authors don\'t know what SQUIDs are or how
they\'ve been used to decades to find buried minerals. This new sensor
senses gravity not magnetism, but it\'s not new in using quantum devices.

Suppose we had a big cube of concrete with unknown stuff inside. Might
be cannon balls, basketballs, marble busts of Groucho Marx. Assume a
movable g-sensor, like a scope probe, that measures its point vector g
field.

Can we wave that probe around outside the block and image the insides?

Look at how that house appears on that example picture.

I think yes
