地球力场地球磁场是地球上所有生命的保护者，一直受到致命宇宙辐射的不断攻击。我们所生活的这种无形的防护罩在南大西洋上空的某个地区正在减弱，使其暴露于潜在的致命辐射之下。地球会失去磁场并注定要遭受类似于火星的命运吗？许多科学家认为答案在于古磁数据，而这种减弱可能是磁场反转的先兆。科学家们知道地球早就该到了。但是，当最后一次逆转发生时，人类不在身边，这对生命意味着什么？Earth's Force Field The Earths magnetic field, the protector of all life on Earth is under constant attack from deadly cosmic radiation. This invisible shield that we live in is weakening in a region over the South Atlantic, leaving it exposed to potentially lethal radiation. Is the Earth losing its magnetic field and doomed to a fate similar to Mars? Many scientists believe the answer lies in paleomagnetic data, and that this weakening may be a precursor to a magnetic field reversal; scientists know Earth is long overdue. However, humans were not around when the last reversal took place, so what does this mean for life?
