Not unless you know Doctor Who. The TARDIS is a spaceship that travels through both space and time. It can go everywhere, and arrive everywhere, almost instantly.
as in: https://www.youtube.com/watch?v=OrFpjh4KF4U (by the way, she suffers a terrible and awkward fate long before this episode, where they "first" meet, ever aired. such is the nature of unlimited spacetime travel, awkward).
so, bascally, if Doctor Who would be real, the tardigrades might be a consequence to the dirt sticking at the bottom of the TARDIS.
