Something seems to be missing from the universe, and the favored model of physics calls it “dark matter” – but despite a century of searching, it remains a no-show. A new paper proposes an alternative ...
In any direction! The distance between the Earth and the Sun is a careful balance between the mass of the Earth, the mass of the Sun, the speed with which the Earth orbits the Sun, and the strength of ...
All fundamental forces operating on astronomical scales exhibit a decrease in strength with increasing distance. A hypothetical force, decreasing with distance slower than the inverse square law, ...
Physicist Markus Aspelmeyer vividly remembers the day, nearly a decade ago, that a visitor to his lab declared the gravitational pull of his office chair too weak to measure. Measurable or not, this ...
ALMA reveals that gravity reorients magnetic fields in 17 young clusters, aligning them as gas collapses and accelerating ...
A bundle of magnets and glass had a slight but detectable gravitational pull, pushing scientists closer to the boundary between classical and quantum physics. Reading time 3 minutes Despite keeping us ...
Scientists have measured gravity at an extremely short distance, in what they hope will tell us more about extra dimensions. The rest of this article is behind a paywall. Please sign in or subscribe ...
The Force is With You? You may have heard that gravity isn’t a force. This is true. Gravity is not a force; however, this truth leaves us with a number of questions. For example, we’re commonly told ...
Evolution in plants and animals is closely linked to changing environments. However, life is not only shaped by its surroundings. There are limitations to form and function, imposed by the fundamental ...
