前往地球中心会有什么感觉？这是一个无法想象的热和压力的地方，没有生命可以生存。但是如果没有它，我们将会灭亡，因为它掌握了我们在这个星球上生存的关键。在地表以下数千英里处，地球核心在行星周围产生了保护性磁屏蔽。现在，科学家发现了这种装甲可能会褪色的证据。这个防护罩中的薄弱点是否表明我们的星球的磁极处于翻转的边缘？What would it be like to travel to the center of the Earth? It is a place of unimaginable heat and pressure, where no life could survive. Yet without it we would perish for it holds the key to our existence on this planet. Thousands of miles below the surface, Earth's core generates a protective magnetic shield around the planet. Now, scientists have uncovered evidence that this armor could be fading. Are weak spots in this shield a sign that our planet's magnetic poles are on the verge of flipping?
