Without heliocentrism (and its extension to other stars), it seems that the entire idea of going to space and colonizing the stars would not be on the table, because we wouldn’t fundamentally even understand what stuff was out there. Since colonizing space is arguably the number one long-term priority for utilitarians, heliocentrism is therefore a groundbreaking theory of immense ethical importance. Without it, we would not have any desire to expand beyond the Earth.
I tend to prefer dealing with applications, not implications

Colonizing the universe is indeed an application.
