A straightforward math tweak could bring tachyon fields into line with the rest of physics. Tachyons are faster-than-light particles, and tachyon fields are special cases of quantum field. The math ...

In the past quarter century, astronomical observations have led to discoveries that have literally transformed our conception of the universe. One such transformation occurred in 1998, when dark ...

All bodies in a given gravitational field are thought to fall with the same acceleration. This idea, known as the equivalence principle, is central to our understanding of gravitational physics. It ...

The concept of black holes originated from Albert Einstein's 1915 theory of general relativity, specifically Karl Schwarzschild's 1915 mathematical solution that described the structure of space-time ...

Recent advancements in observational techniques have led to the capture of high-resolution images of black hole shadows, which are challenging the completeness of Einstein’s general theory of ...

Valerio Faraoni receives funding from the Natural Sciences & Engineering Research Council of Canada. It took Albert Einstein 10 years to find the equations of general relativity, but German ...
