What does it mean to be to space-time? The seemingly simple question gets to the essence of twentieth-century physics and has ...

Few ideas in modern science have reshaped our understanding of reality more profoundly than space-time—the interwoven fabric ...

“Using newer mathematical tools, my colleague and I have demonstrated a new theory that may accurately describe the universe.

Just as ocean waves shape our shores, ripples in space-time may have once set the Universe on an evolutionary path that led to the cosmos as we see it today.

(via Sabine Hossenfelder) Scientific magazines and websites have been raising quite the hubbub about the Amplituhedron, a geometric structure that can be used to simplify calculations in particle ...

Space-time assumes a shape analogous to a whirlpool with walls that swirl more and more steeply as you go farther in; at the bottom, the curvature of space-time is infinite. The vortex is inescapable; ...

Seeking endorsements for her new book, Chanda Prescod-Weinstein finds herself staring at fundamental questions of space, time ...

A decade after the discovery of the “amplituhedron,” physicists have excavated more of the timeless geometry underlying the standard picture of how particles move.

Any time we try to take a hypothetical model and connect it to the real world, we have to introduce special numbers. These numbers capture some aspects of nature that are left outside our equations.

Photographs of 3D-printed shapes show soft cells derived from space filling polyhedra. Blue is derived from a truncated octahedron, pink is from a hexagonal prism and green is from a cube.
