【流浪地球】刹车时代（下）中英文对照(3)

三个多世纪前，天体物理学家们就发现太阳内部氢转化为氦的速度突然加快，于是他们发射了成千上万个探测器穿过太阳，最终建立了这颗恒星完整精确的数学模型。巨型计算机对这个模型的计算结果表明，太阳的演化已经向主星序外偏移，氦元素的聚变将在很短的时间内传遍整个太阳内部，由此产生一次叫氦闪的剧烈爆炸。之后，太阳将变成一颗巨大但暗淡的红巨星，它膨胀到如此之大，乃至地球将在太阳内部运行！事实上在这之前的氦闪爆发中，我们的星球已被气化了。
Three centuries ago, astrophysicists discovered that the fusion of hydrogen to helium inside the Sun had abruptly accelerated. In response, they launched more than 10,000 probes straight into the Sun. Ultimately they managed to establish a precise mathematical model describing the celestial body. Using this model, supercomputers calculated that the Sun was already on the verge of evolving away from the main sequence, ending its hydrostatic equilibrium and with it, its life – living heat and light. It was projected that there was only a short time before the fusion of helium would spread through the entire Sun, causing a runaway explosion, the so – called helium flash. After the flash, the Sun would transform into a huge but dim reed giant. It would grow so large that the Earth would be inside the Sun, as if swallowed into the Sun! In fact, that could never happen bcausee the preceding helium flash would hav already vaporized the Earth.
