“Heim’s attempt to heal this divide added four “sub-space” dimensions to Einstein’s four, making a total of eight. Later he decided that two of the dimensions were unnecessary, and removed them from the theory. His two sub-space dimensions coupled the forces of electromagnetism and gravity, which meant that theoretically, electromagnetic energy could be converted into gravity. This is the principle that his hyperdrive idea was based upon. The theory was so compelling and the math worked out so well that after Heim announced it, Wernher von Braun– the man leading the Saturn 5 rocket program– contacted Heim and asked him whether the Saturn 5 was a waste of money.”
