IN works on relativity little mention is made of the plane in which light travels in four dimensional space. If we assume that a small body sends out rays of light in a three dimensional plane at ...

This is difficult to visualize, as we can only perceive the world around us as a three-dimensional space, and even more challenging to measure. An example of a four-dimensional object is the ...

To get a four-dimensional hyperspace, we take our three dimensional space and throw in a new axis, somehow at right angles to everything. This is super-hard to visualize, but this is why we have math.

A new study from the University of Eastern Finland (UEF) explores the behavior of photons, the elementary particles of light, ...
