This is The Point at Which Our Universe Collided with another

Something strange has been observed in space for more than 15 years - scientists don't know what it is. Some believe this spot could be the result of a collision with a parallel universe, while others say it could be something else altogether. Take a look at this map to see where our universe actually exists. This is not the map of our universe - it's the map of CMB, or cosmic microwave background radiation, which many billions of years ago created our entire reality. An event like this couldn't happen without leaving some traces, and these traces are all around us.

The electromagnetic radiation that we know as 'CMB' was left by the Big Bang. If you had some kind of superhuman ‘vision’, you would see how everything around you shines with this dim light. This radiation is very important, and without it we would never have found out about the Big Bang. Scientists believed that the Universe had always existed, but they didn't have any proof. Stephen Hawking was one of the first scientists to figure out that the Universe had a beginning. Unfortunately, he had no proof to support his argument. If there was such a strong Bank billions of years ago, then where are the traces? Where's the proof? People who believed in the 'Eternal Static universe theory' were completely backed against a wall when Arno Pienzas and Robert Wilson discovered CMB in 1965, and they had no choice but to accept it.

It was revealed that radiation had been present all around us, albeit unnoticed. In fact, initially, Pienzas and Wilson themselves had mistaken it for the commotion of a bustling city or perhaps the cooing of pigeons. However, for their groundbreaking discovery that completely upended the realm of science, they were awarded the prestigious Nobel Prize.

Upon realizing that electromagnetic radiation enveloped their surroundings, people began to diligently gather more information about it. Over the years, they accumulated an ever-expanding wealth of data, which ultimately led to the creation of the remarkable map we see today.

This map, depicting Cosmic Microwave Background (CMB) temperatures, harbored an unexpected revelation during its creation. Let's delve into this intriguing chart. At first glance, it may appear as though it portrays a vast and intricate pattern of warm and cold regions. However, the truth is that our universe exhibits a remarkable uniformity. The temperatures represented on this map all hover near a frigid negative 455 degrees Fahrenheit, with only minor deviations. These seemingly minuscule temperature fluctuations, depicted as tiny specks on the map, actually extend across millions of light-years.

In our mostly calm and stable universe, there exists a rather remarkable exception – a peculiar cold spot. Astronomers first stumbled upon this enigmatic phenomenon back in 2004. Initially, it didn't appear particularly unusual; it was merely a region where temperatures dipped below the average by a few microkelvins. However, it's important to note that this isn't just any ordinary cold area; it's a colossal expanse, spanning billions of light-years.

This unexpected cold spot left scientists perplexed, as it defied the expected uniformity of the universe according to our standard model. The prevailing consensus was that such a cold spot should not exist. Yet, there it was, undeniably present in the cosmos. This wasn't a mere mathematical anomaly; it was an observable reality.

So, what exactly is this enigmatic cold spot, and how did it come into existence? Astronomers have been grappling with these questions for years, and to date, only a few theories have emerged. Let's explore them.

Theory One: Cosmic Texture

Back in late 2007, an intriguing notion emerged. Some scientists posited that this cold spot might be akin to the hills and valleys of space—an uneven region, essentially part of the universe's texture. However, this explanation was met with skepticism and was swiftly discarded due to its seeming simplicity.

Theory Two: The Supervoid

For a time, the leading hypothesis revolved around the concept of a "super void." This theory appeared to be the most plausible explanation.

It was initially proposed that the mysterious cold spot might be attributed to a colossal void in the universe, often referred to as a "supervoid." This dark and desolate expanse of space is characterized by an extreme scarcity of galaxies. Because it lacks the usual cosmic matter, it appears cold to our observations. However, this explanation was debunked in May 2017. Upon meticulous examination of the cold spot, scientists found no evidence of a super void in the vicinity. Furthermore, the known voids and supervoids in our universe are minuscule compared to the expansive cold spot, making it clear that an alternative explanation was needed.

Theory Three: A Parallel Universe.

This audacious and controversial proposition was set forth by cosmologist and theoretical physicist Laura Mercenia Houghton. She posited that the cold spot might be an imprint resulting from a collision between our universe and a parallel one. According to Mercenia Houghton, conventional cosmology fails to account for a cosmic void of such colossal proportions. She boldly asserted that this cold spot represents an unmistakable trace left behind by another universe, one that exists beyond the bounds of our own.

This assumption by Laura Mercenia Houghton is grounded in the Multiverse theory, which posits the existence of an infinite number of universes similar to our own. According to this theory, these universes continuously collide, imparting a force that triggers new Big Bang events. So, perhaps the cold spot in our universe is a cosmic "bruise" resulting from such a collision.

In the realm of quantum mechanics, such outlandish theories are not uncommon. However, they are profoundly groundbreaking and challenging to reconcile with the principles of standard physics and our conventional understanding of the world. Naturally, strong evidence is required to substantiate these claims.

Laura Mercenia Houghton's research team has embarked on the quest to gather such evidence, with the participation of Professor Tom Shanks from the Center for Extragalactic Astronomy at Durham University. Remarkably, the Multiverse theory, despite sounding incredibly audacious, aligns with our current model of the universe, making it the most "standard" among the exotic explanations for the cold spot, as noted by Professor Shanks in one of his works.

To validate the Multiverse theory and the collision hypothesis, researchers like Professor Shanks assert that we should expect to find another cold spot if there was indeed a collision between two universes. This second cold spot would likely be located in the opposite northern hemisphere of the universe, providing crucial corroborative evidence.

The confirmation of this theory would mark a groundbreaking milestone, providing the first tangible evidence for the existence of a parallel universe. However, uncovering a second cold spot is no straightforward task; it demands cutting-edge, highly sensitive telescopes and a deeper understanding of the nature of dark energy and its influence on space. In essence, there is still a substantial amount of work to be done.

There was a recent instance where scientists believed they had stumbled upon a second cold spot. Researchers in New Mexico thought they had pinpointed it in the northern hemisphere. Regrettably, it appears that this discovery may have been a result of the high degree of randomness in the map they employed. It's conceivable that their findings were merely a fortuitous outcome caused by other voids.

To date, despite meticulous scrutiny, a second cold spot has remained elusive. Nevertheless, it's essential to acknowledge that even the most advanced modern equipment has its limitations, and the absence of evidence does not equate to evidence of absence. The quest continues.

If, one day, we do manage to discover a second cold spot, it could revolutionize the realm of science. Such a revelation would not only affirm the theory of parallel universes but also shed light on the famous String Theory, potentially explaining many of the mysteries of our world. Nonetheless, such a discovery would bring forth an array of new questions: How did these two universes collide, and how does this phenomenon operate? As of now, these inquiries remain in the realm of speculation, and we may never definitively uncover the truth. Nevertheless, the pursuit of knowledge in this enigmatic domain remains an endlessly fascinating endeavor.
