There is a giant cosmic void and we are living inside it


There is a giant cosmic void and we are living inside itOur milky way and everything in it exists in an enormous void in space that is without stars, galaxies, and planets. Voids is entirely an empty space that occupies around 80 percent of the observable universe. The other junk such as dust, stars and galaxies similar to the Milky way exists in thread-like filaments in between these voids. Scientists from the University of Wisconsin-Madison said presence within one of these empty regions would sort out our problems related to astronomy—specifically, the rate at which the universe appears to be expanding. As the universe expands, gravity drew matter into clumps and leaves behind a cavernous sphere.

This giant cosmic void does contain some galaxies but they are very dark and invisible. They have very fewer stars and galaxies than other regions. In 2013, Amy Barger discovered that the milky way appears to be located in a large void in space. The scientists at the University of Wisconsin-Madison thinks our own Milky Way galaxy may float near the center of one of these voids. The size of this void is estimated to be 1 billion light-years.

They showed a presentation that how our existence inside a void helps in explaining discrepancies within various measurements of the Hubble Constant. This unit Hubble Constant is used to describe the universe’s expansion rate and evidence suggests its expansion rate is accelerating day by day. The measurement is taken by calculating the distance between a supernova or by measuring light from just after the cosmic microwave background (CMB).


Some of the astronomers noticed bright objects like Cepheid stars or supernovae in the nearby cosmic neighborhood, analyzing their light to determine how fast they’re moving away from the Earth. Different dimensions give different results and the dimensions of the local universe turn out to be higher than those gleaned from the early universe. But astronomers are still unaware whether these discrepancies are a result of statistical fluctuations or hints of new physics.
