Abstract

The cosmological dust has begun to settle. A likely picture is a universe comprised (predominantly) of three components: ordinary baryons ( $Ω_{B} \approx 0.05$ ), non-baryonic dark matter ( $Ω_{D a r k} \approx 0.22$ ) and dark energy ( $Ω_{Λ} \approx 0.7$ ). We suggest that the observed similarity of the abundances of ordinary baryons and non-baryonic dark matter ( $Ω_{B} / Ω_{D a r k} \approx 0.20$ ) hints at an underlying similarity between the fundamental properties of ordinary and dark matter particles. This is necessarily the case if dark matter is identified with mirror matter. We examine a specific mirror matter scenario where $Ω_{B} / Ω_{D a r k} \approx 0.20$ is naturally obtained.
