Gravitational energy is the potential energy a physical object with mass has in relation to another massive object due to gravity, so, does an object outside a gravitational field have no gravitational potential energy?
For example, the Earth is 4.5 billion years old, so it's gravity stretches 4.5 billion lightyears, meaning objects further than this aren't affected by Earth's gravity. Once Earth's gravity reaches them, do they gain potential energy? How does this work?
