I understand that we live in a 3D world. X,Y,Z...Up-Down, Left-Right, Frontwards-Backwards. But I hear theoretically ideas of the 4th dimension, time? As well as String Theory with as many as 11-dimensions. Are any of these higher/lower dimensions provable? And is the 4th dimension that is talked about fairly often correlated with the 4th dimension of the 11-dimensions of String Theory? As well is our 3D space the first 3 Dimensions of the 11-dimesional string-theory world? or is this something completely different?(adsbygoogle = window.adsbygoogle || []).push({});

Thank You
