Lorentzian geometry forms the mathematical cornerstone of modern spacetime theory by providing a framework in which the causal structure and metric properties of the universe can be rigorously ...

The geometry of spacetime forms the very foundation of modern gravitational theory, where the elegant interplay between curvature and matter is described by Einstein’s field equations. In this ...

Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama ...

When speaking of our universe, it's often said that "matter tells spacetime how to curve, and curved spacetime tells matter how to move." This is the essence of Albert Einstein's famous general theory ...

Mark Van Raamsdonk proposes a unification of quantum mechanics and gravity. Both quantum mechanics and gravity theories have been abundantly verified through experiment, yet the realities they ...

Equal Opportunity and Non-discrimination at Princeton University: Princeton University believes that commitment to equal opportunity for all is favorable to the free and open exchange of ideas, and ...
