That might be true from my own frame of reference but not so to an observer, right? How can we say there are 3 spatial dimensions at all if what you say is true

That might be true from my own frame of reference but not so to an observer, right? How can we say there are 3 spatial dimensions at all if what you say is true? What you’re describing suggests there are an infinite number of dimensions based on the different frame of reference for all observers. Why do we then believe there to be 3 dimensions? Is this just one of the cases where 3 dimensions is a useful model for calculation but not really true in reality?
Undoubtedly there must be something I’m missing here—I’ve taken physics courses but clearly I’m no expert. :)
- wbsss4412 4y agoUnfortunately I am not well versed in relativity, my response was completely rooted in linear algebra. That is, any vector is going to be inherently one dimensional, regardless of its coordinates. Dimension is a property of a set of vectors, dependent upon how many are linearly independent of the rest of the vectors in the set. What I described doesn’t imply that there are infinite dimensions. The vector [0,0,1] is traveling through three dimensions just the same as [1,1,1].
