Feynman diagrams keep track of what might happen by stringing together lines representing particles’ trajectories through space-time.

A while ago, we introduced the space time diagram. It's just a graph of position in space-- just one special dimension for simplicity-- versus position in time.

Scientists develop a means of creating 'hopfion' crystals, complex, knot-like patterns of light that repeat across both space and time.

(via Minute Physics) This video is chapter 2 in my series on special relativity, and it covers spacetime diagrams, rotational and translational symmetry of both time and space, how certain ...

It is suggested that concepts and notions from the latter may contribute to the advancement of the conceptualization of action at a distance and agency in general in time-geography, as well as the ...

This dimple in space-time is the result of what we call a gravity well, and it was first described over 100 years ago by Albert Einstein's field equations in his theory of general relativity.
