We study the possibility to probe the spatial geometry of the Universe by
supernova measurement of the cubic correction to the luminosity distance. We
illustrate with an accelerating universe model with infinite-volume extra
dimensions, for which the 1$\sigma$ level supernova results indicate that the
Universe is closed.
