Their work introduces a new concept called q-desics, short for quantum-corrected paths through space–time. These paths ...

By Anil K Rajvanshi A new theory in Physics, as enunciated by Gunther Kletetschka, tries to unite quantum physics and gravity ...

Albert Einstein's general theory of relativity describes gravity as the warping of space-time geometry by mass, a concept distinct from Isaac Newton's absolute space and time, and has been empirically ...

Oftentimes, we think of space as an endless, mostly empty vacuum, a silent backdrop where planets, stars, and galaxies play out their dance. We also think of time as something separate, a steady ...

For decades, quantum physics and general relativity have stood as two powerful but separate theories. Quantum physics explains the behavior of tiny particles like atoms and photons. General relativity ...

Scientists observed a spinning black hole dragging space and time as it tore apart a star, confirming a key prediction of Einstein’s theory of relativity ...

Let’s talk about quantum gravity experiments that can be done here on Earth! If we discover how to connect quantum mechanics with general relativity we’ll pretty much win physics. There are multiple ...

It was already a mind-bending shift, last century, to go from Isaac Newton’s absolute space and universal time to Albert Einstein’s four-dimensional space-time, which is dynamic, flexible, sensitive ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time and the latter a point in space, but in both cases the normally ...

A team of scientists has developed a recipe for black holes that eliminates one of the most troubling aspects of physics: the central singularity, the point at which all our theories, laws and models ...

One way to longer life may be higher gravity—at least for rats. That is the “very tentative suggestion” of experiments performed by NASA Physiologist Jiro Oyama, who has been raising mice and rats ...
