Using a previous cosmological solution of the present author, the behavior of luminosity distance is analyzed in multidimensional spacetime. It is observed that the de Sitter spacetime sets an upper limit to the absolute distance of any cosmological source where the generally accepted value of the deceleration parameter q(0) greater than -1 is taken. This generalizes an earlier result of Barnes to higher dimensions. Further, an attempt is made to investigate, in brief, the phenomenon of nucleosynthesis in the early universe. While it is premature to make a definite statement in this regard, it is found that there may be significant differences, in principle at least, from the analogous situation in four-dimensional spacetime. 15 refs.
