Actually, the solution is that of the Gordian variety. If it's a hollow sphere, then cut it in half, turn each half inside out, and superglue it back together. Other than that, I can't imagine another solution. Also wonderful Scrooge McDuck (Alan Young incarnation, naturally) impersonation. Unless you were just going for a general Scottish brogue. I just read it in Scrooge McDuck's voice because Childhood.😋
LOL No, that was done in my finest Montgomery Scott accent, lass. ;) (aka MY childhood)
If there's no way to *break* the surface of the sphere, then you'd need to look beyond physics. I'm thinking a black hole/singularity, where the laws of physics break down.
Also, you may run into a problem since the inside surface area of the sphere would be infinitesimally smaller than the outside surface area, so you'd have a wrinkle. or a gap. That is if the sphere is not a ball ;)
From Wiki: While outside mathematics the terms "sphere" and "ball" are sometimes used interchangeably, in mathematics a distinction is made between the sphere (a two-dimensional closed surface embedded in three-dimensional Euclidean space) and the ball (a three-dimensional shape that includes the sphere as well as everything inside the sphere).
*looks around* Have we lost everyone? Did I mention that I love reading books about physics for pleasure? I adore Tyson and Kaku.
You should check out this book: https://tinyurl.com/yacedjmd It even has a cow on the cover ;) That's due to the 20-year-old 'joke' about spherical cows in space (I'm not kidding!). I actually have the previous edition of this book, which has this cover: https://www.goodreads.com/book/show/195155.Fear_of_Physics
