Some of the universe’s densest objects can twist, stretch, and resonate in ways that challenge even the most seasoned physicists. Neutron stars, the remnants of massive stars that have exploded as ...

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 ...

Neutron stars harbor some of the most extreme environments in the universe: their densities soar to several times those of atomic nuclei, and they possess some of the strongest gravitational fields of ...

If you’re superstitious, a black cat in your path is bad luck, even if you keep your distance. Likewise, in quantum physics, particles can feel the influence of magnetic fields that they never come ...

Gravity is a ubiquitous part of our daily lives — whether we’re being tragically brought to our knees after tripping on the rug or gleefully jumping from a swing’s apex. But despite how common the ...

Studying the complete spectrum of the General Theory of Relativity and beyond: from the vast dimensions of the universe down to the incredibly tiny dimensions of strings - in Potsdam-Golm.

The study of relativistic effects in gravitational fields remains at the forefront of physics research, refining our comprehension of space‐time and its intricate interplay with matter. Notably, ...

For decades, physicists have struggled to develop a quantum theory of gravity. But what if gravity — and space-time — are fundamentally classical? Most physicists expect that when we zoom in on the ...

Ultra-accurate simulations of the gravity field guide toward a new mathematical foundation of gravity modelling. A layered Earth. (Courtesy: iStock/AlexLMX) The Earth is not a perfect sphere. This ...

The fabric of spacetime may be frothing with gigantic gravitational waves, and the possibility has sent physicists into a tizzy. A potential signal seen in the light from dead stellar cores known as ...

Four fundamental forces are known in physics: the weak and strong interactions, and the electromagnetic and gravitational forces. The gravitational force is the weakest of these four. For this reason, ...
