How do skyscrapers not collapse?

Unlike trees, skyscrapers are mostly hollow, and composed of individual units, and so fall into themselves. Another reason they don’t fall sideways is their unbelievable weight.

What keeps buildings from falling?

Simplest explanation is the foundations are built very deep, which makes the center of gravity of the structure beneath the ground so it is impossible to topple it over without decoupling it from the foundation.
