Do dimensions even really exist?
- 0x264 5y agoOh yes, they do :)
- legohead 5y agoDon't know why I got downvoted, it was a serious question. Can you give an example of how we've made use of the 4th, 5th, 6th dimension, etc.?
- gorloth 5y agoHigher dimensional geometry can show up in lower dimensional problems. This numberphile video (https://www.youtube.com/watch?v=6_yU9eJ0NxA https://www.youtube.com/watch?v=6_yU9eJ0NxA) involves a puzzle about throwing darts at a dart board which is solved by using the volumes of 4+ dimensional spheres.

- f0xtrot 5y agodoesn't 4th just include time with a 3d object. Would things like waves/pulses fall under that? 5th seems to be used in the Kaluza-Klein theory[0] for gravitation and electromagnetism.

It was a thought provoking question.
- srean 5y agoWhat do you mean by exist ? Do real numbers exist ?
- legohead 5y agoWith sufficient technology could we take advantage of higher dimensions for travel or other purposes, for instance.
- srean 5y agoOh you are mixing Physics and Maths. You are asking whether the space we live in has many dimensions, this article about is about the mathematics of spaces that does have many dimensions. One can use the mathematics of such spaces to, for example, find stored images nearest to a query image, nearest document to a query document and so on.
