Effect On Life
Without the outer core, life on Earth would be very different. Convection of liquid metals in the outer core creates the Earth's magnetic field. This magnetic field extends outward from the Earth for several thousand kilometers, and creates a protective bubble around the Earth that deflects the solar wind. Without this field, a larger proportion of the solar wind would directly strike the Earth's atmosphere. The presumed effect would be to strip the Earth's atmosphere away slowly. This is hypothesized to have happened to the Martian atmosphere, rendering the planet effectively lifeless.

“Before the effect one believes in different causes than one does after the effect.”

“In effect it seemed to him that, though honor might possess certain advantages, yet shame had others, and not inferior: advantages, even, that were well-nigh boundless in their scope.”

“I have almost forgot the taste of fears.
The time has been, my senses would have cooled
To hear a night-shriek, and my fell of hair
Would at a dismal treatise rouse and stir
As life were in’t. I have supped full with horrors;
Direness, familiar to my slaughterous thoughts,
Cannot once start me.”
—William Shakespeare (1564–1616)
