Abstract
Robert Forward proposed a gravity machine according to the EinsteinÂ’s general relativity theory. But It requires ultra dense matter, which has the density of a dwarf star, to produce a thrust and it cannot be realized by our conventional technologies. Thus the author propose a gravity machine utilizing an intense electromagnetic field that produces sufficient thrust to propoel the spaceship acording to the EinsteinÂ’s general relativity.
