Is there another earth inside are eath?
The hollow earth is a myth. The idea has been suggested many times throughout history, and there is not only no evidence to support the idea, there is plenty of evidence to disprove it. The evidence includes observation of the earth’s poles from space (no holes), the force of gravity (a hollow earth would weigh less and so have less gravity), and earthquake waves (they obey the laws of physics, and only a solid earth with a liquid outer core accounts for the observed waveforms).
