      the earth’s circumference is, almost by definition, 40000 km

      Big enough so that something approximately spherical looks locally flat. Around 200 million square miles in surface area.

      It’s roughly six thousand km to the center of the Earth, and about 40 thousand km to travel all the way around in a straight line.

      I know that if you were to travel straight through the centre of the earth using only gravity it would take 42 mins to come out the other side. You’d be crispy fried and porbably have been crushed by the gravity, but could still do it.
