Talk:4D

I understand that this is made to suggest things about the subject but, I have a question involving the "4D" Idea, how can 4D exist? 3D is length, width, and height so how can the fourth dimension be time, space, or timespace as they are not sides, vertices, or faces that are measurable and are PART OF THE OBJECT, every other dimension is part if the object but the fourth is just allowed to not be, it can just be different and nobody asks why, I am a man of patterns and this is no pattern. So I leave you with the question, how can 4D exist?

THIS IS COMPLETELY MY IDEA, I DIDN'T EVEN GET INSPIRATION FROM AN OUTSIDE SOURCE!!!

It is a topic of geometry, a branch of mathematics. Geometry is about things that don't exist; cannot exist. There is a reason you have never touched a straight line, a circle, a cube, a point with no dimension. These are all creations of the mathematical imagination. However, people have found ways to picture them, and ways to use them. Four-dimensional objects are less easily represented and have fewer uses, but they are not less real.

Mavin Malign The fourth D as I see it is “symmetry”. Time and space are just positions available to objects. Real ones. Nothing in nature exist without it. Sometimes it takes a bit of study to see but it is in every natural thing just like height, width, and depth. Reality!!!!

Common 4 dimensions (4D)

The correct term is the common 4 dimensions (4D): 3D 'regular space' + 1D time. 2601:589:4801:5660:3023:384D:BBF8:E280 (talk) 11:12, 25 May 2021 (UTC)
