Quantized Gravity and Cells at Planck Scale

A novel experiment tests Planck masses and a quantized gravity. The Planck mass 2.2 x 10^[-8] kg is an observable quantity similar to a flea's egg. We place two spherical sub-Planck masses on a level low-friction surface, grounded within a vacuum chamber, and observe for gravitational attraction. A negative result indicates that gravitational mass is quantized at the Planck scale. Quantum mechanics has applications for astrobiology and living cells, explaining why most cells are limited by the Planck mass. A living cell exchanges material within its walls through processes such as diffusion. In the process of mitosis, chromatids containing genetic material migrate to opposite ends of the cell. If the cell were larger than Planck mass, self-gravity would interfere with its internal processes. This continuing research connects cosmology of the large Universe with the microscopic world
