What If Earth Doubled in Size?

The video explores a hypothetical scenario where Earth doubles in size, examining the effects on gravity, weight, and biological adaptations. Increased gravity would make everything heavier, affecting human and animal physiology, and causing trees to collapse. Volcanic activity would rise, altering continents and climate. The video concludes with fun facts about Earth's dimensions and rotation.

How would increased gravity affect human bones initially?

• Bones would crumble under the increased weight

• Bones would become stronger immediately

• Bones would become lighter

• Bones would remain unaffected

What long-term change would occur in human legs due to increased gravity?

• Legs would become weaker

• Legs would evolve to be stronger

• Legs would remain the same
