Something similar might be a useful exercise (e.g. cold fusion, maybe?). Hollow Earth has way too many immediate implications (so, how does gravity work? and why is GPS functioning? and lots of ways to see through hundreds of miles of atmosphere, shouldn’t radars show us the Earth is concave if it’s so? etc.)
