According to scientists a recent study performed on an anomaly in space that has captivated the imagination and awe of experts for years has provided evidence that there could be another, parallel “bubble universe” out there. The new study was published in the Royal Astronomical Society (RAS).
Scientists have been left amazed by a massive anomaly in the universe. Referred to as the cold Spot, it stretches a staggering 1.8 billion light years across. But the size of it isn’t what has captured the interest of experts but rather its temperature. Scientists have found that it is cooler by around 0.00015 degrees Celsius (0.00027 degrees Fahrenheit), something that experts discovered by measuring the background radiation throughout our universe.
The Cold spot was thought to be cooler simply because it contained less matter than other sections in the universe. Astronomers even nicknamed it a massive supervoid and calculated that it contained around 10,000 galaxies less when compared to other areas of the universe.
However, in a recently published study of galaxies, experts from the Royal Astronomical Society (RAS) say they have discovered that this super void should not / could not exist.
The discovery doesn’t explain the temperature anomaly.
In fact, scientists believe that the galaxies in the cold spot are grouped together next to smaller voids located within the cold spot. However, experts note that these smaller voids are unable to account for the different temperature that scientists observed.
So, what does that mean exactly?
Good that you ask. In order to make a connection between the temperature variation and the smaller voids said to exist in the cold spot, astronomers believe a non-standard cosmological model is required.
“But our data place powerful constraints on any attempt to do that,” explained researcher Ruari Mackenzie in a RAS press release.
“The voids we have detected cannot explain the Cold Spot under standard cosmology. There is the possibility that some non-standard model could be proposed to link the two in the future but our data place powerful constraints on any attempt to do that,” added Mackenzie.
And even though the new study had a large margin of error, the simulations show only a 2% chance that the Cold Spot formed randomly.
“This means we can’t entirely rule out that the Spot is caused by an unlikely fluctuation explained by the standard model. But if that isn’t the answer, then there are more exotic explanations,” said researcher Tom Shanks in the 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 further, more detailed, analysis of CMB data proves this to be the case then the Cold Spot might be taken as the first evidence for the multiverse – and billions of other universes may exist like our own.”
In order to fully understand what exactly the cold spot is, further studies will need to be done. However, if newer studies support the discoveries made in the recent research, the Cold Spot could be the first ever DEFINITIVE evidence of another universe in existence or the multiverse theory. The Multiverse theory states that many different universes exist in space, of which our own universe is only one.
