The universe’s accelerating expansion has long puzzled physicists. For decades, dark energy, an unseen force thought to make ...

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study ...

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

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 ...

A framework that relies on college-level mathematics could describe what happens to particles in so-called spacetime rips, gravity fluctuations such as those that occur during the birth of a black ...

The lecture will be held virtually. To inscribe into the learnweb course please send an e-mail to (heitger at uni-muenster dot de) or (raimar at math dot uni-muenster dot de). General Relativity: ...

General Relativity, Einstein’s seminal theory of gravitation, remains a pillar of modern physics by describing gravity as the curvature of spacetime. Nonetheless, persistent questions—ranging from the ...

One hundred years ago this Wednesday, Albert Einstein gave the last of a series of presentations to the Prussian Academy of Sciences, which marks the official completion of his General Theory of ...
