Hi Karolina,
Could we please put:
Inhomogeneous Cosmological Models Andrzej Krasinski Cambridge University Press 1997 ISBN 978-0521481809on our list of priority books whenever there's some budget money that needs to be spent? (Sometimes at the end of the year there is money that will be lost if it doesn't get spent.) It seems we don't have this book anywhere in the UMK library system.
The Universe is certainly inhomogeneous - UMK would not exist if the Universe were perfectly homogeneous (since LSS and galaxies and planets would not exist). The question is not *if* the Universe is inhomogeneous, the question is *how important* the inhomogeneity is, i.e. to what degree assuming a perfectly homogeneous model and then adding perturbations is a good enough approximation to reality.
