Electric Universe: The Rumour That Gravity Is Only a Small Part of the Story

When people look at the night sky, they are usually taught that gravity is the main force arranging everything. It pulls dust into stars, stars into galaxies and keeps planets in orbit.

It is plasma: gas whose electrons have separated from atoms, carrying electric charge and responding to electric and magnetic fields. NASA describes plasma as nearly all visible matter in the universe.
