科学家们推测，太阳亮度的微妙变化激发了尤卡坦半岛灾难性的气候变化，从而可能触发了玛雅文明的毁灭。这项新研究用淤泥湖底的岩芯证实：当地遭受几千年来最严重的干旱时，正是玛雅文明衰落开始加速之际。太阳的活动有一个“２００年震荡”，不同的研究给出的周期在２０６年 Scientists speculate that subtle changes in the brightness of the sun inspired the catastrophic climate change in the Yucatan Peninsula, potentially triggering the destruction of the Maya civilization. The new study, which uses rock cores on the silt lake, confirms that when the region was hit by the worst drought in thousands of years, it was the Maya civilization whose decline began to accelerate. The sun’s activity has a “200-year concussion”, and different studies give a period of 206 years
