Abstract: Materials are made of atoms, atoms are made of nuclei and electrons, and the speed of light is the universal speed limit. How did humanity learn that this is true? Largely from brilliantly ...

At least when it comes to physical reality, which I define here as that which exists in the cosmos, there is no such thing as complete emptiness. Quite the opposite, it seems that the more we learn ...

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 ...

If the recent discovery of gravitational waves emanating from the early universe holds up under scrutiny, it will illuminate a connection between gravity and quantum mechanics and perhaps, in the ...

Produce and detect gravitational fields at will using magnetic fields, control them for studying them, work with them to produce new technologies -- it sounds daring, but one physicist has proposed ...

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to merge Einstein’s smooth space-time with the jittery world of quantum mechanics. A new wave of ...

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, ...

Zone of divergence: A section through the centre of mass, O, of a planet and the single point, S, on the surface of the planet that touches its Brillouin sphere. The point O is the centre of the ...

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 ...

You see this all the time in textbooks: This is often described as "the acceleration due to gravity". Is this really the best thing to call this? No. A better name would be "the local gravitational ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. In a moment over 100 years in the making, the 2017 Nobel Prize in ...
