Vertical axes: time since Big Bang in billions of years, scale factor a. Shown are the Particle Horizon (brown), Event Horizon (red), Hubble Radius (blue). The horizontal black line describes the present. Past and future light cones (orange) are animated. Dashed grey lines are lines of constant comoving distances (i.e. the Hubble flow).
