Space found in Space !
Even though the universe is so vast and spread out the density of stars and galaxies remains relatively constant and predictable across all of existence.
There are however
some regions that are completely unexpected with very little matter whatsoever
and the largest of these is known as the Boots Void. At around 330 million light
years across it represents around 0.27 percent of the observable universe and
is an incredibly large region of space. Often referred to as a super void it's
around 700 million light years away from us and is remarkably empty.
Current estimates suggest it only has around 60 galaxies in it. Whereas a similarly sized region in most other parts of the universe would be expected to have around 2,000 Galaxies.
To put this into perspective if our galaxy the milky way was in the
center it would only have been in the past few decades that we've had any idea
that other galaxies actually existed as for the reason behind this massive void. No one has any idea at all. It's possible that it grew so large after the
merging of several smaller voids that acted like bubbles and pushed matter out
of the way.
But we simply don't have enough of an understanding of the universe to fully explain this process.
