For a long time, scientists have been baffled by a weird oddity far away in space: a mystifying “Cold Spot” around 1.8 billion light-years across.
It is colder than its surroundings by roughly 0.00015 degrees Celsius (0.00027 degrees Fahrenheit), a fact astronomers uncovered by measuring background radiation through the universe.
However, in a recently published study of galaxies, a team of astronomers from The Royal Astronomical Society (RAS) say they have found that this supervoid could not exist and they believe that the galaxies in the cool spot are clustered all over smaller voids that occupy the spot that is cold like bubbles. All these small voids can’t explain the temperature dissimilarity detected.
To connect the temperature differences to the smaller voids, the researchers state a non-standard cosmological model would be needed. “However, our data place strong limitations on any effort to accomplish that,” explained researcher Ruari Mackenzie in a RAS media release. Even though the study had a huge margin of error, the simulations indicate there is a two percentage possibility that the Cold Spot formed randomly.
In case more detailed studies affirm the findings of this research, the Cold Spot might prove to be the case to be the first evidence for the multiverse, though far more evidence would be required to ensure our universe is indeed one of the many.
