Inhomogeneous Cosmology
摘要
TheCosmologyinhomogeneous Universe is quite inhomogeneous on small scales ( \({ < }10\) Mpc). Stars, planets, galaxies etc. have formed. We already see inhomogeneities in the CMB spectra. Although the universe was much more homogeneous at the time of photon decoupling than it is today, the small inhomogeneities at that time could have acted as seeds for today’s inhomogeneitiesInhomogeneityCosmologyinhomogeneous.
