In v=x/t, t must be a scalar quantity like speed, not a vector like velocity. Time cannot be a coordinate, but it could be the difference between two coordinates, delta-t.
When (in what equation) would time ever be a coordinate?
In the Minkowski matrix, what is time (-ct)?
? Why must r be greater than zero ?
Never mind... this is getting off on a tangent. My question was about Time being viewed as a vector in the Minkowski flat space matrix (flat space is when it is a diagonal matrix). So far everyone has agreed that Time must be a scalar, not a vector...
My comment was that coordinates mean nothing without an origin. The relation of coordinates with the associated origin does define a vector. But, that's not my question.
t=0 is a reference, not a time. I'm trying to think of time in any context which is not actually Δt. Is there any equation...
You could add these vectors. I don't know why you would want to but it is mathematically permissible.
t is a scalar multiplier. If time can speed up or slow down then the multiplier might change in relation to a location in space (the depth of a g-field) or to the particular motion of the...
Coordinates are always vectors. Coordinates refer to a space-time location in reference to an origin. Without an origin and an axis system there can be no coordinates. Drawing a line from the origin to the coordinate always produces a vector. If it were not a vector then the sign, plus or minus...
In the equation x = vt it is generally accepted that x and v are vectors and that they have a common eigenvector. Each vector is the product of a scalar and a unitary eigenvector. Dividing both sides by v works because in x/v = t the x and v vectors have identical and canceling eigenvectors...
