Gravity used to be the most down-to-earth of ideas, the thing that kept apples falling and planets in line. Now a growing ...

Doing the persnickety calculations of how fast clocks tick on Mars relative to Earth, two scientists have discovered that ...

Indian mathematician Srinivasa Ramanujan’s formula for Pi can help with calculating black holes, studying percolation, or ...

As physicists search for a theory of quantum gravity, new results show that classical gravity can still interact with quantum fields to allow matter to become entangled. When you purchase through ...

Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other fundamental interactions (electromagnetism, strong force and weak force) ...

Gravity is the unseen force that shapes the universe, yet we rarely give it much thought. First explained by Sir Isaac Newton, it is the pull that draws objects toward one another based on their mass ...

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in ...

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the ...

‌A urine concentration test provides the specific gravity of your urine. This measures your kidneys’ ability to balance water content and excrete waste. It is important in diagnosing some health ...

All the fundamental forces are thought to be carried by a particle, but a new mathematical model suggests gravity may be a striking exception. Building on a decades-old idea, researchers have revealed ...

Solvej Balle’s “On the Calculation of Volume” rethinks the familiar story of the endlessly repeating day. By Hilary Leichter Hilary Leichter is the author of the novels “Temporary” and “Terrace Story.
