### How is a pseudo-Euclidean metric superior to Minkowski's complex metric? [duplicate]

This is my second attempt to get a meaningful response from you guys on this issue. The SR invariance formula makes space-like intervals imaginary (e.g., the distance $x$ in a given frame has ...

### How well does the concept or model of imaginary time work? [duplicate]

In order to make the Minkowski metric, in special relativity, equivalent to the Euclidean metric, one idea is to allow time to take imaginary values. As far as I have learned about SR, it does make ...

### Why the imaginary unit in time axis? [duplicate]

Why time is not like other dimensions is a real amount? In relativity time axis is $i*c*t$, where $i$ is the imaginary unit and $c$ is light speed in free space. Did science or philosophy reached to ...

### Is time intrinsically complex? Does it have an imaginary component? [duplicate]

In twin paradox, there is an unaccounted area in the unaccelerated frame of its Space-time diagram when one frame's simultaneity is being mapped to the other; ergo period motion of pendulum in one ...
