We report a theoretical demonstration for the creation of space
time holes based on birefringence of reflection, transmission and
the Goos H\"{a}chen shifts from a chiral medium. We observed space
time holes in the reflection, transmission and their corresponding
GH-shifted beams. Two space time holes are clearly detected in the
regions of $0<t\leq5\tau_0$ and $-5w\leq y\leq 5w$ as well as in
the regions of $-5\tau_0\leq t\leq0$ and $-5w\leq y\leq 5w$.
These space time holes hide objects and information contents from
observers and hackers. The objects and information contents are
completely undetectable, thus events can be cloaked. The results
of this paper have potential applications in invisibility of drone
technology and secure communication of information in telecom
industries.
