When we look into space, it feels endless. But does that mean the universe is truly infinite? Science doesn’t yet know. The observable universe has a clear limit — about 93 billion light-years across. This boundary exists not because the universe ends there, but because light from beyond that distance hasn’t had enough time to reach us since the Big Bang. What lies beyond the observable universe remains unknown. It could continue endlessly… or it could curve back on itself. Infinity is not something we’ve proven. It’s something we haven’t ruled out.
