Black holes and space-time singularities have played a hugely important role in explaining some of astronomy's greatest mysteries, but also in popular science-fiction entertainment shows and books. However, the newest model of the Universe, developed by a Nobel Prize-winning scientist, has no room at all for thi... |

An international research effort, made up of scientists from the United Kingdom, Taiwan, and Spain, has recently taken a considerable step forward in furthering the field of photonics research, when it has developed a new, efficient light source for scientific experiments. Photonics is the science of manipulating pho... |

Many people believe that things such as teleportation, invisibility cloaks and time travel pertain only to science-fiction movies and books, but renowned theoretical physicist Dr. Michio Kaku believes that they may be a lot closer than we think. The expert, who collaborated in creating the string theory, reveals that... |

Albert Einstein's famous theory of general relativity and the quantum mechanics theory are two of the most complete methods we have of explaining our surrounding realities. However, each of them only describes a part of the Universe, so an idea that would unify the two has been sought for over the last decades. ... |

The General Theory of Relativity, developed by the brilliant physicist Albert Einstein, has been at the forefront of modern physics, describing the way gravity, space and time interact. However, it does not account for the movement of elementary particle. The theory of quantum mechanics was devised around 1920, and e... |

Over the past two decades, string theory has been touted as the best chance physics have of combining quantum mechanics with general relativity. This would essentially set the basis for the long-sought-after Unified Theory of Everything (UTE), which would include all the four essential forces in the Universe – ... |

At first glance, black holes and qubits seem to be two completely different entities and indeed they are, although they seem to share a great deal of resemblances. For example, last year, Michael Duff from the Imperial College London first demonstrated a connection between the entropy of a black hole and the ways thr... |

What better way to understand the universe than to create your very own? Of course, black holes, supernova explosions and Big Bangs are off limits for laboratories on Earth, but helium-3 cooled to only 17,7 degrees Celsius above absolute zero will do just as good in replicating the processes that took place soon afte... |

As they travel through space, black holes often bursts off radiation and cosmic flares, which, according to Virginia Tech Blacksburg researchers, could provide yet again with evidence that extra spatial dimensions exist. In the 1970s, British physicist Stephen Hawking revealed a solution to black holes, predicting th... |

We can normally see or experience only four of the dimensions of the universe, three spatial dimensions and a temporal one, but can we be certain that there aren't any others? Ever since it was first constructed, the string theory model of the universe seemed to suggest that the world we live in cannot possibly ... |

They say the string theory is not real science, but merely a science fiction description of the universe. This is mostly due to one thing: the string theory makes predictions than cannot be tested in real life, thus it cannot be proven and is falsifiable. For example, the string theory proposes that elementary partic... |

String theory predicts that the universe could be populated with entities of pure mass-energy called cosmic strings, which are basically defects in the space-time fabric that are create while spacetime suffers a rapid change in phase. Such changes in phase might have taken place in the early stages of the universe, d... |

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... |

One of the most intriguing physical puzzles related to quantum physics and particle physics is a property of the protons, which all elementary particles share, called spin. The spin number, or quantum momentum, represents the particle's rotation around its own axis, but unlike the gyroscopic instruments and spin... |

The universe we live in has a beginning, the Big Bang, no definite end since we cannot yet comprehend its whole structure, and nothing, not even time for that mater, exists outside of it. The concept of a cyclic universe has been mostly created to help physicists in their effort to understand its complexity. It is wi... |

The first man ever to consider the possibility of multiple universes was Hugh Everett III, a brilliant American mathematician and quantum physics theorist. Later he became a successful defense contractor with access to the nation's most sensitive military secrets, after which his live turned tragic as he became ... |

For years now, the Standard Model has been used by physicists as the main theory in studying the universe. After the electric and the magnetic mixed into the electromagnetic force, and after the release of Einstein's theory of relativity, scientists tried to unify the remaining forces - gravity, strong nuclear f... |
