Welcome to the Science Mondays segment! Each week here on Geek Alabama, Science Mondays will feature stuff from the world of science and science related content. Our goal here at Geek Alabama is to hopefully have you learn something useful and fulfilling. Science is a geek’s best friend, and we love featuring science content here at Geek Alabama.
Is Earth’s core a solid or a liquid? Yes. The mysteries of our own planet’s interior have, in many ways, been harder to crack than those of the rest of the cosmos. We can send probes to the edge of the solar system, and the 42 billion light years to the cosmic horizon are largely transparent—a big enough telescope can see the most distant galaxy. But the 6400km to Earth’s center are both opaque to light and far beyond the reach of any conceivable drill. The best we can do for most of our planetary depths is to listen to the faint rumblings of distant earthquakes and then try to piece together how those seismic waves bounce around the interior.
