How does gravity shape the universe's architecture?
Quick fact
Gravity is the attraction between objects with mass, and it shapes everything from falling objects to the movement of galaxies.
Why this is interesting
Gravity feels like a simple force pulling things down, but it is actually one of the most fundamental features of how the universe works.

Understanding How does gravity shape the universe's architecture?
Newton described gravity as a force between masses, while Einstein later explained gravity as the effect of massive objects bending spacetime.
A deeper explanation
According to general relativity, objects do not simply pull on each other through empty space. Mass and energy change the geometry of spacetime, and objects follow those curves. This explains phenomena such as planetary orbits, gravitational waves, and black holes.
