Nuclear fusion advances, but challenges remain for power grid

Nuclear fusion originates in our sun and other stars. Immense pressure and high temperatures in the core create a reaction, ultimately preventing it from collapsing under the force of gravity."The fusion here on Earth has a lot of corollaries to how we understand how the stars work in things like astrophysics. They both rely on studying plasma, the fourth state of matter.
