Maybe a nitpick, but I'm pretty sure that modern physics theorizes nothing of the sort, and that the possibility of a large (unfolded) 4th spacial dimension is directly contradicted by phenomena such as the inverse square law in electromagnetic radiation.
- Cookingboy 12y agoThat's completely wrong, many theories in modern physics theorizes "hidden" spatial dimensions. Look at M-theory/string theory for example, 11 dimensions is the prediction. Here is an example of a theory that is related to gravity: http://home.web.cern.ch/about/physics/extra-dimensions-gravitons-and-tiny-black-holes http://home.web.cern.ch/about/physics/extra-dimensions-gravi...
- bashinator 12y agoIt's not completely wrong, the article is not talking about a compacted spacial dimension, it's talking about a large, unfolded fourth spacial dimension.
- WhitneyLand 12y agoRight, the misunderstanding here is that "4d" = spacetime, which is not necessarily true. Generally speaking 4d is just a mathematical model, and our universe/classical physics is only one interpretation.
