Around 550 million years ago the earth's magnetic field almost collapsed, but then strengthened a few million years later. Scientists say this may have been due to the formation of the inner core. But why exactly would that cause the magnetic field to get stronger?

We're often taught that objects travel to lower energy states to reach stability. But the energy of the universe is constant - doesn't that just mean other surrounding things go to higher energy states? What decides which thing gets to have low energy?

If sites like Karahan Tepe could date to potentially 12,000 years ago, where inhabitants where hunter gatherers (with maybe minimal early agriculture) and pre-pottery. Then why don't we see anything 15k, 30k, 50k, or even 100k years back?
