Richard Feynman's famous diagrams embody a deep shift in thinking about how the universe is put together.

Feynman diagrams look to be pictures of processes that happen in space and time, and in a sense they are, but they should not be interpreted too literally. What they show are not rigid geometric ...

(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 ...

With that in mind, Monika Schleier-Smith (pictured above), a physicist at Stanford University in California, is trying to create space-time from scratch.

Why so many “elementary” particles? Why four forces? How do dark matter, dark energy, gravity and space-time fit in? Answering these questions is the work of elementary particle physics.

Physics What is space-time? The true origins of the fabric of reality A bold new perspective suggests space-time isn’t a fundamental entity but emerges from quantum entanglement, says physicist ...

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.
