The idea is not new. If you kept going, and going, there is no edge of the Universe to come to. So what happens? You don’t disappear. You eventually arrive at your starting point.
Sees odd that calculations that don’t come out as expected could trigger a complete revision of the theory of the Universe.
They don’t even know if the Universe is finite or infinite. Resolve that question and then you can move on to other important questions.
It is either infinitely finite or finitely infinite..............
