For a long time, the Greenwald limit was accepted as a given and incorporated into fusion reactor engineering. The new work shows that precise control over how the plasma is created and interacts with ...

Reproducing on Earth the reactions that power the Sun to create an abundant and clean energy source has been a long-standing ...

Researchers working on China's fully superconducting Experimental Advanced Superconducting Tokamak (EAST) have experimentally ...

Most planetary systems contain worlds larger than Earth but smaller than Neptune, and the low-density planets around one ...

China's artificial sun breaks density limit that caused fusion experiments to fail, moving closer to clean energy.

First, let’s look at gravity. On the surface of the Earth, the usual model for gravitational force is the object’s mass times the gravitational field (represented by g) where g is about 9.8 Newtons ...
