Actually, you are confusing the general theory of relativity with something else. The general theory – Einsteins gravitational theory, says nothing about Earth per se, but in a generic sense relates gravitational attraction to a potential well created by the mass of a given object.
Actually, you are confusing the general theory of relativity with something else. The general theory – Einstein’s gravitational theory, says nothing about Earth per se, but in a generic sense relates gravitational attraction to a potential well created by the mass of a given object. For example, the Sun as the most massive object in our solar system creates the potential well that defines and determines how and at what rates the various planets orbit around it. Earth, in like manner, will create its own gravitational potential well, and this determines whether artificial satellites, for example, will be held in orbit and for how long. Also, the velocity needed to escape Earth gravity entirely and become a literal “space ship” like Pioneer 10. The escape from any potential well will thus depend on achieving an escape velocity such that the object can be displaced from Earth orbit entirely. (Which is usually computed using Newtonian mechanics, and not general relativity). My point here i
