"In fact, it is because of this presumed rapid heat loss that
mainstream scientists were surprised when data from the Mariner 10 spacecraft revealed that Mercury still has a magnetic field.
This is because ‘planetary dynamo’ theories attempting to explain how a planet can maintain a magnetic field over eons of time require a molten liquid core within the planet.
But because of Mercury’s small size, Mercury’s core should have cooled off long ago, making it impossible for such dynamo behavior to continue.
*The survival of Mercury’s magnetic field and ongoing contraction are much easier to explain if Mercury was created recently.
Indeed, indications of relative youth are abundant throughout our solar system."
