According to modern cosmological models, the visible universe appears to be made up of 4 - 6% "normal matter" while the remaining 94 - 96% is made up, disproportionately, of "dark matter" and "dark energy". Also, modern cosmology shows that immediately after the "big bang" there was only a tiny more matter created along with anti-matter. The ensueing annihilation of complimentary particles, converting matter and anti-matter into gamma radiation, left matter as the winning majority component of the current universe. But, is there any evidence that, actually, "annihilated" anti-matter still exist and is the constituants of "dark matter" and "dark energy"?
