In this paper I discuss what we truly know about dark energy. I shall argue that up to date our single indication for the existence of dark energy comes from distance measurements and their relation to redshift. Supernovae, CMB anisotropies and observations of baryon acoustic oscillations, they all simply tell us that the observed distance to a given redshift is larger than the one expected from a Friedmann Lemaitre universe with matter only and the locally measured Hubble parameter.

CMB dipoles and other low-order multipoles in the quasispherical Szekeres model
Quasispherical Szekeres models allow a small but less special observer region for CMB dipole consistency and can accommodate significant quadrupole unlike LTB voids.
