What’s the universe made of? For the most part, we simply don’t know. But scientists are planning to head deep underground to find out…

Over 80% of the universe is made of mysterious stuff called “dark matter”, which is invisible to us because it doesn’t give out any light. The best place to try and detect dark matter is deep underground, shielded from cosmic rays that might block out sensitive readings.

Now, scientists want to move their detection equipment to an even deeper location in Canada, 2km below the earth’s surface. Hopefully all that digging will yield scientific gold.
