hi! I am back after a long time. Though I am not sure anybody even noticed.

In this episode, I talk about why our planet's inner core is solid. There is a misconception that this layer is liquid but it's not. The mantle isn't quite liquid either. So what's the part that's liquid? It's the outer core. This is the reason we have a magnetic field that protects us.

Then again the discussion is pretty brief.

bye! or see you soon perhaps...
