  In this study, considering some gas in the Morris-Thorne traversable wormhole
space time, we analyze the critical temperature of the Bose-Einstein condensate
in the vicinity of its throat. As a result, we obtain the result that it is
zero. Then, from this result, we point out that an analogous state to the
Josephson junction is always formed at any temperatures in the vicinity of its
throat. This would be interesting as a gravitational phenomenology.
