摘要：

A possibility to describe quantum gravitational fluctuations of the spacetime background is provided by virtual D-branes. These effects may induce a tiny violation of the Lorentz invariance (as well as a possible violation of the equivalence principle). In this framework, we study the formation of light elements in the early Universe (Big Bang Nucleosynthesis). By using the Big Bang Nucleosynthesis observations, We infer an upper bound on the topological fluctuations in the spacetime foam vacuum s(2), given by s(2 )? 10(-22).
