The horizon is a long way away but the ocean goes for another thousand miles after that. The next continent is 24 hours away by plane. To get to the Moon takes about a week and Mars is months away. I don’t think anyone will ever get to the next galaxy and the end of the universe is moving away at the speed of light. Actually the horizon is not that far way when I think about it. But I don’t think I should mention all this to the ants on the ground.
