Four Dimensional Space
Of course this is only an extra direction.
Four dimensional space. Time and space are interconnected. You see to a mathematician the fourth dimension can be represented using coordinate geometry and vectors within an algebraic four dimensional space. It typically is more specifically four dimensional euclidean space generalizing the rules of three dimensional euclidean space.
In this case physicists and philosophers talk about a single space time continuum. In mathematics four dimensional space 4d is a geometric space with four dimensions. Four dimensional space and consists of three spatial and one time coordinate.
In essence they appear as different sides of four dimensional space time. That is a space just like our three dimensional space but with one extra dimension. A four dimensional space or 4d space has been derived mathematically years ago.
With no effort whatever i can visualize a three dimensional space and you can too. Mathematically four dimensional space is a space with four spatial dimensions that is a space that needs four parameters to specify a point in it. For example a general point might have position vector a equal to.
Light moving in fourth dimension observed during quantum hall experiment we have already investigated that in the gravity model f t in the four dimensional space we get the friedmann equations according to 12 11. What would it be like. I will just consider a four dimensional space.
