Why is there so much matter in the universe, but hardly any antimatter, and where do matter and antimatter actually come from? These are the questions pursued by a team of researchers from the Institut Laue-Langevin in Grenoble, currently preparing to carry out an experiment destined to measure the electrical dipole ... |

Metals are basically used today in practically any application, due to their strength and durability. However, these two properties can quickly turn against the manufacturer, especially while shaping and cutting large pieces of metal, such as the 'I beams' used in skyscraper construction or other large supp... |

Previously it was believed that the material inside stars is mixed in a homogeneous and predictable way, bringing matter from deep inside the core to the surface and vice versa. However, predictions don't always turn out the way scientists want to. It now seems that increasing the spin rotation of a star renders... |

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 ... |

If it were visible from the Earth with the naked eye, it would appear as a structure eight times bigger than the apparent size of the Moon! Measuring more than 270 million light-years across, the newly discovered cloud is the largest structure of dark matter ever observed. The discovery was made by an astronomer from... |

With the fitting of the last major component of what is now the worlds largest particles accelerator, the build of Large Hadron Collider has been completed. All that remains now is to connect all the smaller components of the collider, in the hope that, by the end of this year, the preliminary experiments may begin. ... |

Interstellar clouds of dust and gas pulled together by gravitational forces often experience instabilities, that can result in spectacular explosions such as that of a supernova. Furthermore, if the individual atoms that compose the respective cloud of gas behave like tiny magnets, the same outcome could be experienc... |

Most of the universe we live in is made of matter, not anti-matter, but, while to create anti-matter particles is extremely easy here on Earth, they immediately decay through what we call anti-particle annihilation, when an elementary particle and its counterpart interact and decay into pure energy, or particles that... |

Try taking a look at the night sky for a while, from time to time. It's kind of boring, isn't it? Nothing ever happens, there is peace and quiet everywhere you look. Or is it? Astronomers say the universe is a chaotic place, where massive explosions take place all the time in order to release large amounts ... |

The universe originated in a Big Bang event more than 13 billion years ago, no doubt about that. However, much of its previous history and complexity misses key elements, which are necessary in order to create an accurate theory of the universe's evolution. As space telescopes get better, they enable us to view ... |

String Theory supporters argue that the universe we live in has eleven dimensions, out of which three spacial dimensions and a temporal one, which define the void and the space-time environment we experience daily. Some of you might say 'Well, the real world we live in has only four dimensions'. That may b... |

It is huge, that's for sure, but no one has seen it or knows what it is; it's invisible and light is not emitted or reflected by it. The enigma of the dark matter has been haunting the astronomers since it was first discovered in the 1970s. It possesses mass and measurable gravitation and an analysis of the... |

This took everybody by surprise: the largest space gap, about a billion light years across and around 6-10bn light years from Earth. This vacuum does not only lack the matter which stars, planets and other space bodies are made up of, but also the so-called "dark matter" too."Not only has no one ever found a void thi... |

Not all stars end in a supernova, but those which do produce one of the most impressive and mysterious phenomena of the Universe, which, although intensively studied in the last decades, is far from being completely understood.A team of scientists at the European Southern Observatory now say they found out what fuel... |

A mysterious dark galaxy continues to puzzle astronomers and the latest pictures taken by Hubble failed to shed some light on the mystery. This galaxy raised many questions about how it formed and its evolutionary path over the history of the universe.About 300,000 years after the Big Bang, atoms of hydrogen and hel... |

This was what a team of Australian and Chinese scientists were trying to find: simple equations describing complex behaviors of atomic systems. This has been the central aim of physics for some time now, and this team says they've got observational evidence of a universal behavior.Peter Drummond and Xia-Ji Liu,... |

Astronomers were able to identify for the first time a dark object that seems to be a double black hole located around 16,000 light-years away from our solar system, using a new technique called cosmic triangulation.In trigonometry and elementary geometry, triangulation is the process of finding coordinates and dist... |

Hollywood movies are full of monsters, bad guys, aliens and mythological creatures, which make the good guys look better after saving the world, or at least some damsel in distress. While some depictions are scientifically documented, some of them are just plain impossible and could only exist in people's imagi... |

A new experiment demonstrated a quantum state exchange between light and matter than can be reverted to the original state. This could help quantum computers overcome one of their biggest problems yet, decoherence.Decoherence is a disruption in the internal systems of a quantum computer that instantly damages the in... |

Saturn is the second largest planet in the solar system, after Jupiter, and also a gas giant. Named after the Roman god Saturnus, it has a prominent system of rings, easy to spot with even a low-end observation equipment.At first glance, Saturn's rings may appear solid when viewed from Earth, due to the density... |

Today's generally accepted view of the distant future has been that today, there is more matter than radiation in the universe and ordinary matter particles - protons and neutrons in particular - will gradually decay into radiation over trillions upon trillions of years, leaving a universe in which radiation on... |

At the center of the Milky Way galaxy, about 26,000 light years away, there is a supermassive black hole estimated to have a mass equal to about 4 million suns.A few bright stars are known to orbit very close to it, and WIMPs (weakly interacting massive particles) may concentrate near this black hole. These particle... |

The quickening pace of our universe's expansion may be driven by a mysterious force called dark energy.Astronomers were astonished to discover in 1998 that the expansion of the universe is happening at an ever-increasing rate. The mysterious repulsive force responsible for this was dubbed dark energy, though sc... |

Scientists have come up with a new tantalizing hypothesis about a new state of matter and space-time. "Twenty five years ago we thought we understood everything about how matter changes phase. Then along came an experiment that opened up a whole new world", said Xiao-Gang Wen at the Massachusetts Institute of Technol... |
