scientist say that super human strength is impossible because we need more muscle mass but what if we made out muscles denser so there are more cells
to do the work of one cell so wouldn't that make us stronger?
Muscle strength is a function of a number of factors, including physiological factors, i.e., size and cross-sectional area as well as mechanical (pennation or angle of pull and muscle moment arm lengths) and neurological (neural drive to muscle) factors.
Increasing the density might be one way to increase strength but, while the force generated by a muscle occurs within the muscle cell, increased density would come at the cost of reduced space for other, equally-important components of the muscle, e.g., reduced space for the sarcoplasmic reticulum, which stores calcium without which muscle contractions simply could not take place. Increased density might also mean that the build-up of lactic acid during sustained contractions might occur faster than could be removed, thus limiting the ability of the muscle to produce force for sufficiently long periods, resulting in muscle fatigue.
