The volcanic dome of Mauna Kea, in Hawaii, has been recognized for many years as one of the most suited locations for building ground-based telescopes. Its unique vantage point allows telescopes built here to make out details of the Universe that can only be seen from only a handful of other places around the world. ... |

Next to the International Space Station (ISS), the Large Hadron Collider (LHC) is arguably the most complex and amazing human scientific project ever constructed. Its main goal is to recreate the conditions that existed just a few fractions of a second after the beginning of the Universe, immediately after the event ... |

According to scientists at the Durham University, the galaxies in the early Universe were highly active when it came to forming new stars, and generated about 50 of the new suns every year. The experts determined that previous estimates about the setup inside these galaxies were a bit off, in that their ability to fo... |

According to the standard cosmological model, the Big Bang – the event that created our Universe – took place about 13.7 billion years ago. After that, the Cosmos began expanding and producing all types of structures, which would eventually differentiate in things we know today, such as galaxy, clusters a... |

The standard cosmological model holds that there is a type of matter known as dark matter permeating the Universe, which accounts for the massive discrepancies that exist between how much matter the Universe has, and the amount it should have, according to predictions. Astronomers hypothesized that dark matter should... |

The nature of time has remained something that has fascinated humans since the dawn of time, and the first division of a day into smaller intervals. Many have wondered about how to split it as accurately as possible, whereas others have been wondering if the concept is derived from physical laws or not. Over the last... |

The “Cosmic Web” is a concept that is often used to refer to the underlying support structure that our Universe has, which we cannot see with our eyes or scientific instruments but know it's there. This web, which is charged with keeping galaxies together, and at times channelling them into superclus... |

Over the next decade, as new-generation telescopes will be built around the world, scientists will need to keep an eye on all datasets that come out of these machines, interpret them, analyze them, and then draw conclusions based on them.

Over recent years, a growing number of astronomers has come to believe that the Big Bang did not create just a single Universe, as in the one we inhabit, but many different ones, which only appear locally uniform. The Multiverse theory is catching wings fast, and physicists have recently taken another step for bringi... |

Understanding the current state of the Universe has less to do with analyzing the way things are now, and more to do with finding out how things were in the early days, when the first galaxies and black holes appeared from the chaos that existed after the Big Bang. For this very purpose, experts with the Sloan Digita... |

During the night of September 14-15, the Baryon Oscillation Spectroscopic Survey (BOSS) experienced its first light, in an event that marked the beginning of a new type of quest for dark matter.

The Kepler Space Telescope, launched earlier this year, is, arguably, one of the best telescopes in the world today, especially when it comes to detecting small exoplanets around other stars.

Though no clear evidence documenting the existence of dark matter was ever produced, astronomers believe it exists because, if not, they simply cannot explain phenomena in the Universe.

It has become widely accepted among scientists that our Universe is roughly 13.7 billion years old. It's also known that the diameter of the observable Universe measures at least 93 billion light-years. However, if this is true, there is a hitch. In 13.7 billion light-years, light can only travel 13.7 billion li... |

While the Big Bang theory is still the most agreed-upon idea on how the Universe formed, the final faith of the Cosmos is still a subject of hot debate among astronomers and physicists. While some say that it will expand to a point where it will become a dark, empty void, others claim that it will eventually contract... |

According to a new complex computer simulation, it would appear that the earliest black holes that where formed after the Big Bang were in fact a lot smaller than the giants they are today. Also, the simulation revealed that older theories, which held that the formations accumulated mass quickly and gobbled up matter... |

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.

It is widely accepted that the Universe exploded into existence some 13.7 billion years ago, when the Big Bang created the first light and the first amounts of matter, which then immediately started expanding.

The Hubble Constant is, in astronomical terms, the value given to the speed at which the Universe expands.

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.

One of the most widely recognized paradoxes of time travel is the circular causality problem, which basically states that the consequence of a phenomenon cannot be said to be its root cause.
