See title. ThisThis planet is a rogue planet without any star or without being volcanically active. On thisAntimatter continually collides with the planet, my idea is that antimatter would continually collide and annihilateannihilates with hydrogen in the upper atmosphere. This would provide heatingprovides heat and lightinglight for the planet. However, my question is
Alternatively, the planet could be made out of antimatter, with regular matter colliding with it. The end result is the same.
Could these conditions allow the planet to support life and allow enough time for life to evolve (10-20 million years). Alternatively, the planet could be made out of antimatter while their is matter hitting it regularly?
