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 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 ...

The theorized unseen structure of spacetime could also explain of the outstanding questions about the accelerating expansion ...

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

The standard explanation has been dark energy, an invisible force added into the equations to make the math work. But now, an ...

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 ...

The rapid acceleration of the universe’s expansion continues to challenge our understanding of fundamental physics. Why the ...

There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...

Spacetime isn’t something that exists; it’s a model for describing how events happen. Treating events as objects creates philosophical confusion and fuels misconceptions, such as time-travel paradoxes ...

A team of Italian researchers has uncovered compelling evidence of anomalous radioactive decay in cobalt-57 (Co-57) under ultrasonic stimulation, offering strong experimental support for the Deformed ...
