The enormous gravitational pressure of so much material compresses and triggers nuclear fusion in the star's core.

恒星由宇宙中最简单、最轻的元素 氢 构成由于巨大的引力。

The higher we build, the higher the gravitational pressure from the upper stories on the lower ones.

我们建得越高，高层对低层的重力压力就越大。

No longer able to produce sufficient energy to maintain its structure, it collapses under its own gravitational pressure and explodes in a supernova.

再也不能产生足够的能量来维持它的结构，它在自身的重力作用下崩溃，并爆炸成一颗超新星。

At those levels of gravitational pressure, blood is sent flying from your brain to your feet, leading to light-headedness or blackouts as the brain struggles to stay conscious.

在这些重力压力水平下，血液从你的大脑飞到你的脚上，导致头晕或昏厥，因为大脑努力保持清醒。
