We discuss the particle horizon problem in the framework of spatially homogeneous and isotropic scalar cosmologies. To this purpose we consider a Friedmann–Lemaître–Robertson–Walker (FLRW) spacetime with possibly non-zero spatial sectional curvature (and arbitrary dimension). and assume that the content of the universe is a family of perfect fluids. plus a scal... https://fitnessgravesyardes.shop/product-category/seat-pad/
