How tall is this building?

Dianna from Physics Girl explores the concept of a hypothetical tall building that could reach the speed of light at its top if only Newtonian physics applied. She discusses the Earth's rotation, centrifugal force, and the idea of artificial gravity. The video calculates the height needed for a building to allow a penny to orbit Earth, revealing it would extend beyond the solar system. The feasibility of such a structure is questioned due to structural and physical limitations.
