und der Coulomb-Konstante

$Bild$

Wenn die Expansion des Universums berücksichtigt wird ist die kosmologische Konstante

Zwei Körper bleiben stationär zueinander wenn das Ladung/Masse-Verhältnis

$Bild$

wobei f eine beliebige Zahl ist. Mit berücksichtigter Expansion ist das Gleichgewicht beim Abstand/Masse-Verhältnis

Notation: Newton. Variablen: M=Masse, Q=Ladung, p=Position, v=Geschwindigkeit, G=Gravitationskonstante, ε₀=Feldkonstante, Λ=Lambda.

Instabile geschlossene Orbits mit 5 Körpern; Periodendauer: 2π sek, M=m³/sek²/G, Schweiflänge: π/3 sek

Stationäre Punkte markieren die Startpositionen. Die Startbedingungen für die Ensembles wurden von Carles Simó ausgearbeitet.

Mehrkörpersimulatoren für Masse und Ladung. Masselose Testpartikel sind erlaubt, ebenso negative und selbstverständlich positive Massen. Geladene Körper müssen jedoch Masse haben da sie ohne im elektromagnetischen Feld aufgrund der ansonsten fehlenden Trägheit unter Krafteinwirkung unendlich stark beschleunigen würden.
