  • I think i do? But earths gravitational field is a potato, which is why constellation satellites like GPS and Starlink need to adjust now and then. And even if it were a perfect sphere, there’s still the moon and the other planets pulling on it. Look at Jupiters Lagrange points for a example how wobbly space around the sun actually is:

    L3, L4 and L5 are fields of pebbles (asteroids) Jupiter pushes/pulls around it’s orbit by deforming space.

    About ripping apart: no matter how high the tensile strength of the material; scale it up enough and it’s a sandcastle. Wikipedia has a small table here for the lightest materials and i think Steel is around 100 km. That combined with the potato grav field of earth and it breaks apart.
