If I compress a spring beyond its most relaxed point it will have more energy and thus by General Relativity produce a stronger gravitational field than the uncompressed spring will. But suppose instead I pull in the opposite direction and stretch the spring beyond its most relaxed point it is my understanding that it would produce a weaker gravitational field than the compressed spring even if they both had the same amount of energy because tension, unlike pressure, produces a gravitational repulsion that would cancel out some of the attraction made by the mass/energy. Am I correct?
