Astronomers have finally watched a black hole do something Albert Einstein only described on paper: twist the very fabric of ...

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

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

If you’re concerned about getting every microsecond out of life, then you might not want to migrate to Mars. Using extremely ...

Wormholes are one of science fiction’s favourite cheats. Need characters to cross impossible distances? Skip years of travel?

Time feels like the most familiar thing in the world, yet it hides one of physics’ hardest questions: why do we only remember ...

The shape of the universe is not something we often think about. My colleagues and I have published a new study that suggests it could be asymmetric or lopsided, meaning not the same in every ...

Black holes are among the most extreme objects in the universe, and now scientists can model them more accurately than ever before. By combining Einstein’s gravity with realistic behavior of light and ...

ABSTRACT: We develop the strong-field and higher-order expansion framework for the NUVO scalar geometry. Starting from the nonlinear field equation R g =− 8πG c 4 T obtained in a previous work, we ...

110 years ago today, Albert Einstein published his General Theory of Relativity, which redefined the relationship between matter and gravity. Suddenly, our mysterious universe made a little more sense ...

ABSTRACT: In this paper, we will use Geometric Algebra to be able to embed the Klein-Gordon equation for a particle in a non-Euclidean field (gravitational field). This way, we will obtain an ...
