NASA scientists have discovered a planet-wide electric field surrounding Earth, confirming a 60-year-old hypothesis. Studying ...
However, all is not lost. Their ultra-accurate simulations of the gravity field offer guidance toward a new mathematical foundation of gravity modelling. An upgraded simulator, which accounts for ...
Perhaps the best way to understand the electric field is to look at another field—the gravitational field. Suppose you have two objects, an apple and similarly sized (but much heavier) rock.
Photons and normal, stable particles both fall as expected in a gravitational field, with Earth causing any massive particle to accelerate towards its center at 9.8 m/s 2.
New research published in Physical Review Letters suggests that superconducting magnets used in dark matter detection ...
A new study is shedding light on why solar radiation is more effective than other forms of energy at causing water to ...
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 field" and list it in units of: ...
Save guides, add subjects and pick up where you left off with your BBC account. All matter has a gravitational field that attracts other objects. The more mass an object has, the greater its ...
It is known that there are two main global fields around the Earth — the gravitational field, formed by the planet’s mass, and the electromagnetic field, formed by the metals of the planet’s core. The ...
