the reason stars don't just leak into the void the second they light up.
means the inward pull a star's own mass generates on itself and everything nearby, constantly fighting the outward push of fusion.
from newton worked out the general law in 1687, but it took einstein's general relativity in 1915 to explain why gravity near something as massive as a star actually bends space and time, not just pulls on strings.
