I'm designing a planet that has reached the top level of civilization.
This species has left behind the need for violence, they have found a way to live in peace with their planet's ecosystem and they have interstellar travel that allows them to visit other universes.
Their economic system is based on knowledge (if someone wants to buy something he or she has to learn something new, the more you learn the more you can buy), they can build massive megastructures and they can terraform another planet within a few hours.
They have achieved immortality and therefore everyone is at the same age (they grow until some point and then stop), they have utopian like cities, there is no poverty there (neither racism or sexism), they have found a way to prevent stars from dying, they think that competition is something pointless and they have found a way to create their own universes or pocket dimensions.
But back to the question: What could their lifestyle be like on their home-world? What could their everyday life be like for them?
Note: I know that people say that a type omega civilization would probably live outside the space-time continuum, but I decided to say that they still live on their home-world.
