  Recently proposed low scale quantum gravity scenario is expected to have a
significant impact on the Mirror World hypothesis. Some aspects of this
influence is investigated here, assuming that the fundamental gravity scale is
near a TeV. It is shown that future colliders will be capable to produce the
mirror matter, but an experimental signature, which will distinguish such
events from the background, is unclear. The `smoking gun'' signals of the
Mirror World would be an observation of decays like $\Upsilon(2S)\to \tilde
\chi_{b2} \gamma $. But unfortunately the expected branching ratios are very
small. Finally, it is shown that a mirror supernova will be quite a spectacular
event for our world too, because a considerable amount of ordinary energy is
expected to be emitted in the first several seconds.
