Advance physics science suggests UFO fusion reactors generate electromagnetic field force that is used to produce kinetic motion in space.
The Sun generates a massive electromagnetic field (EMF) known as the 'Heliosphere' and one can see that the EMF is exerted force that powers the Solar Systems kinetic motion around the Galaxy through space.
The Earth and all planets exert electromagnetic force to power kinetic motion around the Solar System.
All galaxies exert massive electromagnetic force to power kinetic motion around the universe.
The observable universe's electromagnetic field rotates that powers universal kinetic motion.
