When the James Webb Space Telescope first opened its golden mirrors to the dark, it was meant to show us the beginning of time — the light from the first galaxies, the birth of stars, the echoes of creation. But a few months ago, as it scanned the edges of the known universe, it detected something no one was prepared for. A signal. Not radio, not light, but something else — a faint pulse embedded in the fabric of space itself. The coordinates led scientists to a region behind the Hercules–Corona Borealis Great Wall, one of the largest known structures in the cosmos. There, hidden in a void that should have been empty, Webb’s instruments caught a glow — faint, symmetrical, and alive with impossible geometry. What the telescope captured next made astronomers question everything they knew about physics, time, and the shape of our universe.
