Cito:
"There’s no way to calculate the exact answer, since we’re missing a lot of necessary data, but we can certainly guess. The Mountain weighs more than twice what the average man of today does, and he’s about two feet taller. He also has the advantage, within the context of the fight with the Viper, of not relying on muscle strength alone; he has the assistance of gravity and is leaning his entire upper-body weight on Oberyn Martell’s head. At the same time, he has the disadvantage of the fact that his arms are starting out still, so they don’t benefit from any major acceleration; acceleration is why a boxer’s fast-moving punch can generate a force of way more than the 520 required. Despite that, we’re going to say that yes, the Mountain probably could crush Oberyn Martell’s skull into smithereens using only his hands "
científicamente, por la altura de la montaña, + el hecho de la gravedad, y que oberýn estaba acostado, y la montaña tenia todo su peso sobre su cabeza, sería posible hacerle explotar la cabeza como lo hizo
