Scientists Found Evidence That We Live Inside a Cosmic Void

Aug 15, 2026
We live inside a cosmic hole roughly 2 billion light-years across, and nobody told us.

In 2013, astronomers discovered that the local universe has far fewer galaxies than it should, a strange emptiness now called the KBC Void, with the Milky Way sitting close to its centre. That same void might explain the Hubble tension, a stubborn disagreement between two ways of measuring how fast the universe is expanding, one that JWST has already failed to explain away as measurement error.

This video covers the cosmic web, the discovery of the void, the forces pushing and pulling our galaxy through space, and what Euclid and DESI are about to reveal.

Fexl explores the KBC void, a massive under-density in our cosmic neighborhood that challenges the standard cosmological model. By examining how this vast structure might influence measurements of the universe's expansion, the video investigates whether our location in this immense, empty region could be the key to resolving one of modern physics' most persistent debates.
