What we saw in the DESI experiments, and now strengthened by our South Pole Telescope observations, is that dark energy is ...

The general theory of relativity, Einstein asserted, was now complete. The month leading up to the historic announcement had been the most intellectually intense and anxiety-ridden span of his life.

Time, not space plus time, might be the single fundamental property in which all physical phenomena occur, according to a new ...

From four-dimensional hexagons to the mind-bending amplituhedron, geometrical shapes are wilder than we learn at school - and ...

Three intertwined time directions may underpin everything, turning space into mere “paint on the canvas” and pushing physics ...

As the universe expands, it feels like it must be spreading out from some initial point. But a physicist explains why that’s ...

The general theory of relativity has been one of the most successful developments in twentieth-century physics, providing the foundation for our concepts of space, time and gravity. In 1921 ...
