According to new data collected by the astronomers operating the NASA Fermi Gamma-ray Space Telescope, it would appear that the spike in cosmic antimatter particle concentrations the Italian spacecraft PAMELA intercepted in 2008 cannot be interpreted as proof of dark matter.
The research bodes both well and bad for... |

According to the conclusions of a new study, it would appear that the gigantic mass our galaxy has may contribute to underlying the asymmetry in decay rates between matter and antimatter. This phenomenon, called charge-parity (C-P) violation, has remained mysterious for years. The Milky Way has a tremendously large m... |

Researchers working on an advanced physics experiment may have confirmed some of the first signs of CP violation. This could lead to developing a plausible explanation as to why there is more matter in the Universe than antimatter, if equal amounts of the two were produced during the Big Bang.The CP violation is a pa... |

For many years, astronomers have known that the universe is expanding at an ever-accelerating rate. This means that galaxies are flying away from each other, and the preferred explanation is that dark energy is driving this expansion. A new study proposes a new force instead, called antigravity.This force could be dr... |

A team of Canadian investigators at the University of British Columbia (UBC) propose the existence of a new particle, dubbed particle X, that could explain dark matter, antimatter, and also why there is enough normal matter in the Universe for us to exist, all in one fell swoop.

While the most basic theories of physics help explain the world around us through rules, they also have the unsettling implication that the Universe, and naturally everything in it, should not exist. As we are aware, it does. This poses a quintessential dilemma to physicists trying to make sense of it all. At least i... |

In a new series of physics experiments set-up in particle accelerators, researchers were able to account for why we, and indeed the Universe, exists. As any physics expert will tell, we theoretically shouldn't be here. Neither should galaxies, stars, black holes, cosmic gas, and everything in between. Since matt... |

For a long time, astrophysicists have been puzzled by the reason why matter prevailed over antimatter, just seconds after the Big Bang exploded everything into being. According to theory, everything currently in the Cosmos should not have existed. The initial explosion should have produced equal quantities of matter ... |

Regularly, when Earth-based telescopes surveying the skies take notice of a supernova explosion somewhere in the Universe, they record a tiny flash of light, which then shortly disappears, as the remnants of the star spread away from its core. The Nearby Supernova Factory survey, at the Palomar Observatory in Califor... |

Astronomers propose a new theory related to the core of very large stars. They say that, when the inner parts of such a celestial body become too hot, they start forming matter-antimatter pairs. Naturally, when this happens, the basic laws of physics dictate that a violent annihilation between the two occurs, and thi... |

Everyone knows that space is big. The thing about calling the Universe massive and what not is that no one can get a clear image of precisely what type of distances we're talking about. The closest star to our location would take the equivalent of 50 million Earth-Moon journeys to get too, or roughly 4.2 light-y... |

Ever since the standard model was first created, depicting the interactions between all forms of matter, physicists who created it, and all those who came afterwards, drew attention to one of its major drawbacks, namely that it erased us all from existence. That is to say, it holds that matter and antimatter annihila... |

The exact opposite of matter, antimatter, has been known to exist for decades now, although how it behaves in the presence of a gravitational field remains mostly unknown even though countless experiments have been conducted over the years. Each particle described in the Standard Model has its own antiparticle counte... |

Most contemporary scientists would argue that matter and antimatter behave roughly in the same ways, however proving it is some kind of a challenge. Why? Well, mostly because there is hardly any antimatter in the universe today. Creating antimatter particles is relatively easy in our particle accelerators, capturing ... |

The Big Bang theory suggests that, in the early life stages of the universe, a massive number of black holes might have been created. Although not as massive as most of the black holes created from stellar remnants, a part of these tiny black holes might still be lurking through space. In the 1970s, the famous physic... |
