0.000 HBDA: Is it possible that additional extended spatial dimensions exist?
I think the models involving the tiny extra dimensions are pure mathematical ones to give mathematical meaningful solutions to overcome discrepancies with the current models. It doesn´t mean those extra dimensions do really exist. But if, there would be no way for us to detect them. In a higher dimensional universe (no proof of its existence however) we indeed would appear like flatlanders in our universe. By the way, we don´t have to apply the flatlander´s analogy. Already the 4th dimension, the time, is not reachable for us, we can see time only as going by, but we cannot influence it. A truely 4 dimensional being could travel through time like we through 3 dimensions. **StemQ Notice:** *This post was originally submitted on [StemQ.io](http://www.stemq.io), a Q&A application for STEM subjects powered by the Steem blockchain.*
