A hidden dimension the size of a bacterium — that's what the 'dark bubble' model proposes. Gravity on such scales disappears, leading to the accelerating expansion of the cosmos. The microcosm stops playing by Newton's rules.

🎯 A micron (one millionth of a meter) is the typical size of a bacterium. If such a dimension existed, it would literally be under our microscope.
