What if the Earth Were Hollow

The video explores the concept of digging through Earth, considering the Coriolis effect and the challenges of such a journey. It discusses the hypothetical scenario of a pole-to-pole tunnel, the gravitational forces involved, and the reversal of these forces as one travels through Earth's core. The video also examines the challenges of deep digging, such as heat, and the implications of a hollow Earth, including the loss of a magnetic field and increased solar radiation exposure.
