New research suggests our galaxy sits right near the center of the KBC void, an expanse of relatively empty space that's 2 billion light-years wide. Pablo Carlos Budassi / Wikimedia Commons
- Evidence suggests that our galaxy is inside a cosmic void, a vast expanse of relatively empty space.
- But according to our laws of cosmology, this void shouldn't exist.
- New research says such a void may explain unusual behavior in nearby galaxies. ]/ul]
Our home galaxy, the Milky Way, is just one of billions in our universe. So, in the grand scheme of things, we're not so special. But zoom in to our local cosmic neighborhood, and that story begins to change.
A growing list of observations suggests we live in the crosshairs of a giant cosmic void the largest ever observed. Astronomers first suggested such a void in 2013 and evidence for its existence has been stacking up ever since.
But the kicker is that this giant void shouldn't exist in the first place. If it does exist, that means something is probably amiss with our understanding of the cosmos.

According to a fundamental theory of cosmology named the cosmological principle, matter in the universe should be uniformly distributed on very large scales.

They blew the place to shit and left.

(2,527 posts)This makes sense if we are in a simulation, which would have a limited boundary. I'm not saying I believe that, but I do enjoy reading the assorted theories about it (and they are not all nut cases, the ones who discuss this). When I read this, that's the first thing I thought of.
