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 ...

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

The main problem in presenting the work of Einstein to the physicist is to enable him to see how obstinately metaphysical he is. Space and Time in Contemporary Physics: An Introduction to the ...

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 ...

For nearly two decades, Figueiredo’s doctoral advisor, Nima Arkani-Hamed, has been leading a hunt for a new way of doing physics. Many physicists believe they’ve reached the end of the road when it ...

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.
