Abstract
In a quest to explain the small value of the today's cosmological constant, following the approach introduced in Jalalzadeh and Rostami (2015), we show that the theoretical value of cosmological constant is consistent with its observational value. In more detail, we study the Friedmann-Lamaître-Robertson-Walker cosmology embedded isometrically in an 11-dimensional ambient space. The field equations determines Î in terms of other measurable fundamental constants. Specifically, it predicts that the cosmological constant measured today be ÎLPl2=2.56Ã10â122, as observed.
