(Worldkings.org) Studies of the universe and its makeup generally conjure images of astronomers at telescopes, peering up at the galaxies, nebulas and stars scattered across the night sky. But to understand the decidedly less visible, but very important, parts of the universe, such as neutrinos and dark matter, scientists have to take a different approach — namely, by going underground. Of course, it is somewhat complicated to get underground, so scientists how have to get creative. Sometimes researchers work in repurposed mines. Others are required to drill big tunnels themselves to run particle accelerators or study nuclear fuel disposal. These are Top 5 Coolest Underground Science Labs.
