We now know that the number 42 can be written as the sum of three cubes:
\[ 42 = (-80538738812075974)^3 + 80435758145817515^3 + 12602123297335631^3 \]
This computational breakthrough was achieved in a collaboration between Andrew Sutherland (MIT) and Andrew Booker (Bristol). They announced the result by both replacing their homepages with the expression – with the page title Life, the Universe and Everything.
