We propose a framework in which the quantum gravity scale can be as low as $10^{-3}$ eV. The key assumption is that the Standard Model ultraviolet cutoff is much higher than the quantum gravity scale. This ensures that we observe conventional weak gravity. We construct an explicit brane-world model in which the brane-localized Standard Model is coupled to strong 5D gravity of infinite-volume flat extra space. Due to the high ultraviolet scale, the Standard Model fields generate a large graviton… CONTINUE READING
