A closer look

Picture space as a vast invisible sheet, and every planet or star as a bowling ball pressing into it. That sag pulls everything nearby into graceful orbits, not because they’re being yanked by strings, but because they’re surfing the dip. Einstein’s big reveal was that gravity isn’t a force tugging—it’s the shape of the stage itself curving around massive objects. Suddenly, the cosmic ballet makes sense: Earth circles the Sun not from a leash, but from sliding across a warped playground. The universe, it turns out, is less about pull than about paths in hidden hills.
