This direct detection approach involves monitoring a lot of atomic nuclei in a laboratory to see if any get nudged by a dark matter particle. The largest such experiment, XENON1T at the Gran Sasso National Laboratory in Italy, used about 1 tonne of liquid xenon.\" What if everything we know about dark matter is totally <a href='https://www.wired.co.uk/article/dark-matter-worth-searching-for-null-results' target='_blank' rel='nofollow'>wrong?</a> \"There’s a mine, deep underground in Canada, that’s unlike any other...It’s located at a depth of two kilometres – so deep you could easily stack four and a half Empire State buildings into this hole, one on top of the other.
