Future Space
A massive galactic structure may be breaking the rules of cosmology. The Hercules–Corona Borealis Great Wall, detected using gamma-ray bursts (GRBs), could span 10 to 15 billion light-years, far exceeding the size limits set by the Cosmological Principle. If confirmed, it would be the largest known structure in the universe—ten times larger than what physics currently allows. In this short video, we break down how it was discovered, why it matters, and what it could mean for our understanding of the cosmos. Is it a real cosmic feature, or a statistical illusion? Either way, the implications are huge. Subscribe for more space science content, astronomy news, and discoveries that push the boundaries of what we know.
