Earth’s gravitational force, g, has been known for centuries. But the exact value of G, the universal gravitational constant, ...
Measuring the strength of gravity is extraordinarily difficult, and different experiments have always disagreed – but a new ...
By studying galaxy clusters separated by hundreds of millions of light-years, Penn physicist Patricio Gallardo and ...
In quantum mechanics, particles do not behave like everyday objects. Instead of existing in one clearly defined state, they ...
The most demanding calculations in quantum chemistry can now be solved with graphics processing unit (GPU) supercomputers. A ...
A study of 300,000 galaxies confirms that gravity follows Newton's law and deepens the mystery of dark matter.
A study on the ISS found that astronauts over-grip objects because their brains retain expectations of Earth’s gravity.
“With so many unanswered questions, gravity remains one of the most fascinating areas of research,” Patricio Gallardo, one of ...
Gravity has been tested extremely well inside the solar system. On cosmic scales, direct tests are harder. This study pushes ...
Lucas Ye, age 8, designed the stuffed toy that will start floating when the Orion capsule reaches orbit. By Kenneth Chang Reporting from Kennedy Space Center in Florida. When the engines of the ...
