Unknown to me at this point in time. If I recall, we've only drilled 8 miles down. We're between a firmament and ground that hasn't been explored below that depth. Scientists can't confirm their theory that we have a molten core that they've extrapolated from our magnetic fields.

And it's important to note that there are two key descriptors: flat and motionless.

I don't believe that it's a pancake flying through space that many of the debunking videos would point out.

Happy to share resources if you're curious. It's the most amazing red pill that I've taken.
