“Kryptonite is the common ore of the super-actinide kryptonium, an unusually stable trans-uranic element, whose atomic number is believed to be 126. Kryptonium’s half-life is thought to be approximately 250,000 years. Created from the fused elements of the planet Krypton, kryptonite is a substance that is unique in the known universe. No one has been able to duplicate the thermonuclear reaction that created kryptonite. Indeed, all attempts at synthesizing it have been unsuccessful.³⁵”

+: “Kryptonite is the common ore of the super-actinide kryptonium, an unusually stable trans-uranic element, whose atomic number is believed to be 126. Kryptonium’s half-life is thought to be approximately 250,000 years. Created from the fused elements of the planet Krypton, kryptonite is a substance that is unique in the known universe. No one has been able to duplicate the thermonuclear reaction that created kryptonite. Indeed, all attempts at synthesizing it have been unsuccessful.³⁵”
