Ah the space-time continuum. Always something interesting going on there. Where would we be without it? I'll leave this question to you to ponder.
While you are pondering, you can sew up the 17th block of the Doctor Who Along ~ A crack in time.

One note: There are a couple of errors on the numbering scheme in the pattern pieces. I'll get this fixed in a few days, but for now, follow the numbering on the piecing guide and you won't go astray.
Careful you don't get sucked in and end up in another dimension!
One note, you might actually need a bit more than a fat quarter of background fabric for this block. Just a head's up so you don't run out.
Happy Sewing!
