How Long To Fall Through the Earth?

The video explores the concept of falling through a hollow Earth, discussing how gravity changes as one falls. It explains a simplified model assuming uniform density and calculates the fall time as 42 minutes. Adjustments for Earth's varying density show a more accurate fall time of 38 minutes and 6 seconds. The video uses physics principles to explain these calculations.
