- nomel 3y agoThis is discussing a euclidian fourth dimension, not time.
- NomDePlum 3y agoThe cited article is speculating on what the Fourth Dimension is. I'm just pointing out that there is already an accepted answer to that. Nothing to stop others discussing the alternatives.
- qorrect 3y agoThat's Lorentzian geometry and Minkowski space from the 1900's and created for Relativity. This is Euclidian geometry, much older and more 'accepted'.
- r14c 3y agoI imagine there would still be a relationship with `c` in a fourth spatial dimension, but it might be useful for taking shortcuts around 3d space without having to violate causality.
- NomDePlum 3y agoI'm sure you are right on that. I'm going to have to plead ignorance on this. Which will likely not surprise you. I'll have more than the cursory read through the article in an attempt to educate myself.
- eggn00dles 3y agois the spatial curvature described by general relativity due to non euclidean 3d space, or euclidean 4d space where we can only perceive 3d?
