This paper presents a new theory on the creation of dark energy linked to mass destruction, extending Einstein’s mass-energy equation to function under high gravity conditions, revealing a relationship between dark energy and dark matter. It introduces key parameters such as dark energy discriminant and boundaries, explaining that mass destroyed within a defined boundary creates dark energy while outlining gravity's effects on light, causing redshift. The research emphasizes dark energy's significance in cosmic expansion and predicts potential advancements in space travel through negative gravity effects.
