Eddington Limit: The maximum luminosity a star can sustain before radiation pressure causes its outer layers to be blown away.
General Relativity: Einstein's theory that describes gravity not as a force, but as a consequence of the curvature of spacetime caused by mass and energy.
Nuclear Fusion: A nuclear reaction in which atomic nuclei fuse together to form a heavier nucleus, releasing vast amounts of energy, the primary process powering stars.
Spacetime Curvature: The warping or bending of the four-dimensional fabric of spacetime by the presence of mass and energy, as described by general relativity.
