The Urantia Book makes various references to realities not yet discovered here on Earth (as of about 1935.)

“Light, heat, electricity, magnetism, chemism, energy, and matter are―in origin, nature, and destiny-one and the same thing, together with other material realities as yet undiscovered on Urantia.” 472§2

“The mesotron explains certain cohesive properties of the atomic nucleus, but it does not account for the cohesion of proton to proton nor for the adhesion of neutron to neutron. The paradoxical and powerful force of atomic cohesive integrity is a form of energy as yet undiscovered on Urantia.” 479§4

“There is innate in matter and present in universal space a form of energy not known on Urantia. When this discovery is finally made, then will physicists feel that they have solved, almost at least, the mystery of matter. And so will they have approached one step nearer the Creator; so will they have mastered one more phase of the divine technique; but in no sense will they have found God, neither will they have established the existence of matter or the operation of natural laws apart from the cosmic technique of Paradise and the motivating purpose of the Universal Father.” 467§5
