Jun 16, 20048 0 back to setai in post #3 i'm not asking how many dimensions we have thought about, i'm asking how many dimensions have been proven to exist scientifically. Have any experiments been conducted in these extra dimensions, or have any experiments been conducted in 3d to show. Oct 7, 2004the number of dimensions in 'physical space' really doesn't matter in linear algebra, we're not necessaily trying to model 'physical space'.
Whether dimensions 'exist' or not is no. Feb 17, 2004a single dimensional object in 3-space or 2-space would be a point. You wouldn’t be able to see it in three dimensions or two dimensions.
But, the idea of a 1 dimensional. Sep 19, 2020it can only physically exist to us if it has a third dimension. Likewise, a cube is a three dimensional object and would need a fourth dimension to physically exist in a four.
Sep 9, 2009the point is that, assuming that particles can propagate in extra dimensions, many conceptual problems of modern high energy physics find answer. That a universe with 1 dimension of time and 2 dimensions would be too simple for life. I ask because i believe that higher dimensions can explain a lot of things.
Sep 9, 2016the discussion revolves around the challenges of understanding spatial dimensions beyond three, particularly in relation to mathematical representations and physical. Jan 23, 2023it explains that in four dimensions, the intersection of two perpendicular planes of rotation creates two great circles that resemble poles but do not function as equators.
