In the world of physics, the existence of a theoretical X-particle may explain why anything in the universe exists at all including antimatter and dark matter. None of these things can be seen with human eyes, and only some of it, such as anti-helium, may be physically detectable through highly advanced technology. One such piece of equipment is the Alpha-Magnetic-Spectrometer (AMS), designed by scientists around the world and tested at the European Space Agency (ESA).
The X-particle is something some scientists hypothesize contributed to the creation of derivative particles such as neutrons and some anti-matter particles. The key aspect of the X-Particle is it may have biased degeneration that led to the creation of more neutrons than anti-matter. Since matter and anti-matter are believed to be the anti-thesis to each other in a physical attrition of sorts, it raises eye brows as to why more matter exists in the universe if both matter and anti-matter were created equally in the beginning.
The X-particle, if it did degenerate, is proposed to have degenerated into matter and dark matter. However, the existence of an anti-X particle very similar to itself may have also led to the creation of other anti-matter. According to a Wired report discussing the scientists who explain the idea in more detail. X-particles and anti-X particles had different degeneration patterns causing the creation of more matter than anti-matter. Since the degeneration of the x-particles led to the creation of more matter, be it visible or dark, the universe was allowed to exist because there was simply more of it.
The universe is believed to be approximately 23-25 percent dark matter and only 5-6 percent matter according to scientists. Only a small percent of the universe is anti-matter according to Universe Today, but may have contributed as much as 49-50 percent of the universe at an earlier time. Anti-matter is an opposite electric charge to regular matter, and when an equal amount of matter and anti-matter collide, the only thing that remains is ‘pure radiation’ according to a discovery channel documentary. Since more matter does exist, theories such at those pertaining to the X-particle emerge, but there are other theories as well.
The existence of competing scientific theories allows questions to emerge into the validity of the X-particle. For example, is this the same X-Particle discussed in Time magazine and hypothesized by Carl David Anderson and Jabez Curry Street in the 1930’s? Moreover, was the universe indeed created with equal parts matter and anti-matter? Some scientists suggest there was just enough more matter in the beginning of the universe to leave the leftover universe. Universe Today reports other scientists propose matter other than the X-particle called B-mesons are what decayed into matter we know now, and that similar to the X-particle, the anti-b mesons degenerated differently causing more matter to be left after time.
