Just to show everything, top and bottom, this empty public room tumbles end over end. If traveling away from us, it might turn a bit red, and any panicked shouts muffle with pitch change. At night, some people claim the Hubble telescope, occasionally inattentive and inward turned, will ignore the stars and scan the oceans instead, where it finds particularly fascinating the spectacle of the Titanic steamship falling with a similar red-shift, in endless gentle acceleration though the deep waters of the north.     Sometimes there would be a lamp, or a stairway, for decoration.
