‘Dimension hopping’ or ‘dimension manipulation’ could be a solution to the Fermi paradox. The universe could be full of intelligent life that remain silent and (mostly) invisible behind advanced spatial technology.
(the second type refers to more limited hypothetical dimension technology such as creating pocket dimensions, for example, rather than accessing other universes)
