Probing the curvature of the Universe from supernova measurement

Abstract
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 level supernova results indicate that the Universe is closed.
