Can HOLLOW PLANETS Exist?

TL;DR

The concept of hollow planets is explored, but according to physics and observation, it is unlikely that any true hollow planets exist, including Earth.

Key Insights

• 🧑‍🏭 Planets are defined based on hydrostatic equilibrium, where forces of gravity and pressure make solids act like fluids.
• 🌍 Digging deep into the Earth has not yet ruled out the possibility of a hollow Earth.
• 📶 The required strength for a hollow planet shell exceeds the theoretical maximum strength of matter.
• 💯 Without a core and magnetic field, a hollow Earth would be exposed to harmful cosmic radiation.
• 👮 The laws of physics and direct observation suggest that true hollow planets are unlikely to exist.
• 💁 Small objects like dwarf planets can be in hydrostatic equilibrium, but their composition and formation differ.
• 🌍 A mathematical analysis shows that if humans were living inside a hollow Earth, everything and everyone would be weightless.

Questions & Answers

Q: How do we define planets based on hydrostatic equilibrium?

Hydrostatic equilibrium means that sufficient mass overcomes the rigid forces of material, causing solids to behave like fluids. This concept is used to define planets.

Q: Can we determine if the Earth is hollow by digging?

Currently, humans have only dug about 1% of the Earth's radius, so we cannot rule out the possibility of a hollow Earth. However, digging deeper would require incredibly stronger materials.

Q: What is the required strength for a hollow planet shell?

Based on calculations using the equations for a Dyson Sphere, a hollow planet shell would need to withstand immense force, exceeding the theoretical maximum strength of matter.

Q: Can a hollow Earth exist without a core and magnetic field?

Without a core and its associated magnetic field, Earth would be exposed to cosmic radiation, which would be detrimental to life. So, a hollow Earth without these features is unlikely.

Summary & Key Takeaways

• Planets are massive and spherical objects in space, but the idea of them being hollow has been around for centuries.

• To define a planet, hydrostatic equilibrium is used, which means that the forces of gravity and pressure make solids behave like fluids.

• Digging deep into the Earth is not currently possible, so the theory of a hollow Earth has not been ruled out, but its strength would have to be greater than any material known.
