We apply Dicke's theory of superradiance (introduced in 1954) to the 6.7-GHz
methanol and 22-GHz water spectral lines, often detected in molecular clouds as
signposts for the early stages of the star formation process. We suggest that
superradiance, characterized by burst-like features taking place over a wide
range of time scales, may provide a natural explanation for the recent
observations of periodic and seemingly alternating methanol and water maser
flares in G107.298+5.639. Although these observations would be very difficult to
explain within the context of maser theory, we show that these flares may result
from simultaneously initiated 6.7-GHz methanol and 22-GHz water superradiant
bursts operating on different time scales, thus providing a natural mechanism for
their observed durations and time ordering. The evidence of superradiance in this
source further suggests the existence of entangled quantum mechanical states,
involving a very large number of molecules, over distances of up to a few
kilometers in the interstellar medium.
