But wouldn't that mean you would only get to see the sun once in your whole life?
That depends on how fast the world rotates to make one revolution. Even an infinite body is capable of a 360 degree revolution around a central point. The location of the central point may be unknown without more information of the infinite plane of minecraft, but the speed of revolution will help ensure that you do indeed see the sun more than once in your life. The time it takes for one revolution is a 'day', both in the real world and, in theory, minecraft.A lot of math and theory in questions like these!
