M-theory would explain the weakness of gravity relative to the other fundamental forces of nature, as can be seen, for example, when using a magnet to lift a pin off a table — the magnet is able to overcome the gravitational pull of the entire earth with ease.
M理論將解釋重力相對於自然的其他基本力量的弱點，可以被觀測, 例如，當使用磁體將一根針從桌上吸起來時 - 磁體能夠容易地克服整個地球的重力拉力。
