Finitism and Physics – “A brief precis: Gravitational collapse limits the amount of energy present in any space-time region. This in turn limits the precision of any measurement or experimental process that takes place in the region. This implies that …
Gravity in Multiply Connected Space
Author Greg Egan has a new book out, and wrote up an explainer behind the math: “A space that is connected (in the sense that there is always a path between any two points), but not simply connected, is known as a multiply connected space, because ther…
