The Universe Has a Limit, And It's Closer Than You Think

The Universe Has a Limit, And It's Closer Than You Think We like to think of the universe is endless—an infinite expanse of galaxies, a boundless sea of stars stretching forever in every direction, a cosmic canvas too vast to chart. It comforts us, this idea of an eternal frontier, as if discovery will always be possible, as if the answers are just waiting somewhere out there. But what if that’s not true? What if, instead of an infinite playground, the universe is more like a walled garden—expanding, yes, but hemmed in by invisible boundaries we’re only beginning to glimpse? Not poetic barriers, but hard physical limits woven into the very structure of space, time, and information.
