In Brief A recent study on a spaceanomaly 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. Too Cold
For years, scientists have been baffled by a weird anomaly far away in space: a mysteriousCold Spotabout1.8 billion light-years across. It is cooler than its surroundings byaround 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 thanmost sections of space. They dubbed it amassive supervoidand 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.
To link the temperature differences to the smaller voids, the researcherssay a non-standard cosmological model would be required. But our data place powerful constraints on any attempt to do that, explained researcher Ruari Mackenzie in anRAS press release. While the study had a large margin of error, the simulations suggest there is only atwo percent probabilitythat the Cold Spot formed randomly.
This means we cant entirely rule out that the Spot is caused by an unlikely fluctuation explained by the standard model. But if that isnt the answer, then there are more exotic explanations, said researcher Tom Shanks inthe press release. Perhaps the most exciting of these is that the Cold Spot was caused by a collision between our universe and another bubble universe.
If more detailed studies support the findings of this research, the Cold Spot might turn out to be the first evidence for the multiverse, though far more evidence would be needed to confirm our universe is indeed one of many.
