IN BRIEF

A recent study on a space anomaly that has perplexed scientists for years has some suggesting that it could be explained by a parallel "bubble universe" — although there are other, more standard potential explanations, as well.

For years, scientists have been baffled by a weird anomaly far away in space: a mysterious “Cold Spot” about 1.8 billion light-years across. It is cooler than its surroundings by around 0.00015 degrees Celsius (0.00027 degrees Fahrenheit), a fact astronomers discovered by measuring background radiation throughout the universe

Previously, astronomers believed that this space could be cooler simply because it had less matter in it than most sections of space. They dubbed it a massive supervoid and estimated that it had 10,000 galaxies fewer than other comparable sections of space.

But now, in a recently published survey of galaxies, astronomers from the Royal Astronomical Society (RAS) say they have discovered that this supervoide could not exist. They now believe that the galaxies in the cold spot are just clustered around smaller voids that populate the cold spot like bubbles. These small voids, however, cannot explain the temperature difference observed.
