The idea of the existence of a parallel universe is an intriguing one. Realities running side by side with existence, as we know it, is bound to keep us curious.
It’s not new speculation, we have considered the possibilities of a parallel universe for decades, even building theories around the idea. Well, it’s possible that one cosmologist has found the proof that we desire – maybe, maybe not.
From the Institute of Technology in California comes Ranga-Ram Chary, helping us to understand parallel universes. But first, we have to understand how the universe was born. An important term we must be familiar with is recombination. This process is the point in which hot and energetic particles form atoms. Recombination started about 300,000 years after the Big Bang. At this time, CMB (Cosmic Background Radiation) spread across the universe. Now scientists use this process to build theories and take a look into the past.
Within the Cosmic Background Radiation, Chary discovered a “bruise” or imperfection. He believes that this imperfection could be evidence for the existence of a parallel universe. Just as colliding soap bubbles form in water and cause a reaction, the collision of parallel universes could cause the bruise. These collisions can also drop materials along the way.
Chary isn’t convinced that the idea of a parallel universe is a fact. He speculates that what he is witnessing could be a large bit of space dust. He also thinks there is a 30 percent chance that the bruise or imperfection is only background disturbance. These ideas are prevalent in Chary’s mind because of the level of difficulty in testing the CMB.
David Spergel from Princeton University told Joshua Sokol in the New Scientist:
“It would be worth looking into alternative possibilities. The dust properties are more complicated than we have assumed. I think this is a more plausible explanation.”
Sokol adds, “Joseph Silk of Johns Hopkins University in Baltimore Maryland says the idea of a parallel universe is ‘implausible’. He thinks the paper is a good analysis of anomalies in Planck data, but he believes something is getting in the way. ‘My view is that they are almost certainly due to foregrounds.’”
Based on the number of protons and electrons that existed in the early universe, the signals coming in are 4,500 times brighter than they should be. This was discovered when Chary subtracted CMB models from the European Space Agency’s Planck Telescope’s picture of the universe.
Although Chary has good indications, the idea is just a hypothesis. He believes there may be results within a couple years. Then again it’s possible that the task may fall in the lap of the next generation (roughly 15-20 years from now). Looking back into the past is not easy, but progress is always being made. Until proof makes speculation a fact, we keep dreaming.
“Unusual claims like evidence of alternate universes require a huge burden of proof. Searching is and will be a challenge.”
