Boötes Void
AstronomyComments
Imagine the psychological horror of being the only galaxy for 330 million light years. We aren't just crowded, we are practically roommates in a studio apartment.
It reminds me of how city planners deal with dead zones in downtown areas. You can have a thriving metropolis, but a few blocks of empty lots makes the whole neighborhood feel abandoned.
we have the cosmic microwave background to prove density regardless of local voids.
Even if the CMB gives us the big picture, the existence of the Laniakea Supercluster makes our crowded corner of space feel like a fortunate accident.
Recent surveys suggest the void isn't as empty as the original 1981 findings indicated. It is more of a low-density region than a true vacuum.
Do the newer surveys actually narrow the diameter, or are they just finding more low-luminosity objects inside it?
