En el centro de la Tierra

The subterranean world in 'At the Earth's Core' feels both fantastical and immersive. I'm curious whether Burroughs based it on any scientific theories or purely on creative imagination.

The balance between advanced machinery and primitive societies added depth to the story. Did this contrast make anyone else think differently about progress and tradition?

The fast-paced, sensational tone really amps up the excitement. Do you think this style enhances the escapism or limits deeper character development?
