The KBC Void (named after astronomers Ryan Keenan, Amy Barger and Lennox Cowie) is a relatively empty, fairly spherical space region, measuring approximately 2 billion light-years in diameter.

Despite its supposed emptiness, everything you've ever known and loved resides there - not to mention the entire Solar System in which it all resides - the Milky Way that contains the Solar System, the Local Group that contains the Milky Way, and most of the Laniakea Supercluster that contains the Local Group. That's a lot of stuff fitting inside a void.

It can be a difficult thing to get your head around, but basically, Space is a big block of Swiss cheese, and we are a little speck of dust in one of the holes.
