I just read through this thread* where a mathematician tries to shutdown another guys use of the "sphere to donut" analogy relative to ripping spacetime because a sphere is a "2-dimensional manifold". That is so completely and entirely irrelevant when both are still just 3 dimensional shapes, and shapes that are easily changed to and from one another both mathematically and via a CGI representation. I felt the need to comment on the thread but then found out I have insufficient privelages. :*((adsbygoogle = window.adsbygoogle || []).push({});
