The Sun Will Explode in 5 Billion Years

Do you know why there is so much light during the day? It's because of the sun! 你知道為什麼白天那麼亮嗎?當然是因為太陽！ The light from the sun makes everything bright. But have you ever thought of what would happen if the sun… went out? 如果太陽不再發光發熱了該怎麼辦呢？ That is something that could happen, but don't worry. It won't happen for 5 billion years, which is a really, really, really, really long time from now. 這種事情有可能會發生，但不用擔心，是五十億年之後才可能發生。 We know that the sun will still be around for about 5 billion years because very smart scientists figured it out. However, the scientists say the sun won't just burn out, it will actually explode. 科學家說，太陽不只是熄滅，它會爆炸！ When the sun cools down, it will expand, which means it will keep getting bigger, and bigger, and bigger… until it swallows up all of the planets that are near it! 太陽冷卻之後會變得愈來愈大，會大到把它身邊的行星全部都吞掉！ That's scary! And it also doesn't sound like very much fun for anything that is still living on Earth. But good thing we don't have to worry about it, unless we live to be 5 billion years old! 除非我們活到五十億歲，不然我們其實不用擔心！ ________________________________ Vocabulary 沒有了太陽，人類可以存活嗎？ 1.
