Among the challenges facing evolutionists is a serious one of their own making. Their dynamo models expect the early earth’s magnetic field was too weak to protect our planet when life was trying to get a start. Simultaneously, the “faint young sun” was also more active, blasting the early Earth with excess radiation. At The Conversation, Jon Mound and Christopher Davies at the University of Leeds explain,
The habitability of a planet depends on many factors. One is the existence of a strong and long-lived magnetic field.
These fields are generated thousands of kilometres below the planet’s surface in its liquid core and extend far into space – shielding the atmosphere from harmful solar radiation.Without a strong magnetic field, a planet struggles to hang on to a breathable atmosphere – which is bad news for life as we know it. A new study, published in Science Advances, suggests that the Moon’s now extinct magnetic field may have helped protect our planet’s atmosphere as life was forming around 4 billion years ago.
The Moon and Mars have lost their magnetism; consequently, the Moon has only negligible gas around it and Mars has a very thin atmosphere, 1% of Earth’s. The sun’s barrage of solar wind strips away atmospheres over time. This is happening even out Titan at Saturn’s distance. Without a protected atmosphere today, it would indeed be “bad news” for life. Ask Mars all about it.
That red Tesla Roadster with a mannequin driver that Elon Musk launched as a stunt last year is most likely having a hard time in the space environment without the Earth’s magnetic field to protect it. Live Science reported on March 20,
At this point, if you were to go look at the Roadster, it probably would look pretty different. As Live Science
reported in 2018, the harsh solar radiation environment between the planets would probably have wrecked all the exposed organic materials (red paint, rubber tires, leather seats and the like), breaking the carbon bonds that hold them together. And without Earth’s protective atmosphere and magnetic shielding, even the robust plastics in the windshield and carbon fiber materials would start to disintegrate. Over the course of decades or centuries, the car should be reduced to its aluminum frame and sturdiest glass parts — assuming none of them get destroyed in impacts with passing space rocks." CEH
