SUMMARY
This discussion explores a thought experiment involving two 100 kg gold spheres placed 10 billion light years apart in a vacuum. The primary question is whether these spheres will mutually attract each other over time due to gravitational forces. Utilizing principles of energy conservation, participants can calculate the collision velocities of the spheres upon eventual contact. The discussion references a related thread for additional insights on the duration of such a collision event.
