Talk:The Abyss/@comment-79.155.238.125-20200507161653/@comment-4037078-20200930015340

if the abyss is 20,000 meters (20 km) deep, and the inverted abyss is also 20 km deep and leads to the other side of the planet, that makes the Earth 40 km across. The Earth is actually 12 thousand km across. Which is 318 times deeper than what you're suggesting.
