In this paper, we present a covariant formalism that connects solutions to force-free electrodynamics in the non-null case and foliations of spacetime. doing so, are also able derive an expression general current density vector. Just as null case, can give rise dual solution, however, is shown below, happen only when solution describes vacuum field. All theorems illustrated with previously know...

In this work uncovered is that around the hydrogen atom there exists periodical variation of electromagnetic wave. Based on wave theory, interaction between two atoms discussed, which leads to conclusion Gravity not special but just different form force instead.
