University of Oxford theoretical physicist Roger Penrose is convinced that our Universe is not the first of its kind. His newest theory argues that a number of eons occurred before this one, and that the Big Band that spawned our Cosmos is just the latest in a string of many. But how can we test this?What the expert ... |

Analysis of the large-scale flow of galaxies, clusters and superclusters are setting the grounds for new scientific theories that may have been cataloged as “heresies” just a few years back. Researchers are shedding serious doubts on the currently-accepted astronomical model explaining the Universe. One t... |

A famous theoretical physicist in the United Kingdom argues that space and time were not something that appeared when the Big Bang spawned the Universe into being. In fact, they may be much older constructs that simply underlie this Cosmos as they did many other before it. University of Oxford physicist Roger Penrose... |

American investigators have just been granted approval to construct a telescope that will be able to peer back as much as 10 billion years into the history of the Universe, and determine how dark energy shaped it. The findings could help explain how the Cosmos is set up.There are numerous researchers who believe that... |

The search for dark energy is about to get real, experts say. Later this years, a team of astronomers and astrophysicists will begin the Dark Energy Survey, one of the largest endeavors to find the elusive stuff ever undertaken.The study will be conducted using the advanced, 570-megapixel Dark Energy Camera, which is... |

Astrophysicists have a relatively solid background of data about what happened after the Big Bang, and how the Universe evolved to its current form. What they are a little hazy on is the process that took place millionths of a second after the initial event, and which triggered the Cosmic expansion.In a new investiga... |

Though most astronomers believe the the Universe began developing some 13.7 billion years ago, a team now proposes that the Big Bang – the event that set everything in motion – was actually preceded by a larger series of episodes of universal birth and death.It could be that a large series of explosive ev... |

Scientists are nowadays focused on determining how the Universe looked like a very short time after the beginning of the Big Bang. This research leads to new knowledge on the CMB.The event that “ignited” universal expansion is called the Big Bang, and it represents a time of accelerated inflation during w... |

Since the Big Bang theory was first formulated, astronomers and other scientists have been hard at work to either confirm it beyond a reasonable doubt, or show it to be false. At this point, it still remains the most popular explanation of how the Universe cam into being, and is widely accepted by the scientific comm... |

A new challenge to classical cosmology comes from a novel field named loop quantum cosmology (LQC), which started from applying rules of loop quantum gravity on the context of general relativity. The new vision states that the universe we live in did not emerge from an infinitely small particle with a similarly infin... |

In a recent article for the New Scientist publication, there is an interesting scientific explanation to the famous (albeit rather theological) question posed by Saint Thomas Aquinas (1225-1274), "Why is there something rather than nothing?". However, the answer does not involve God, but rather how the universe was b... |

Approximately a decade ago astronomers discovered that not only is the universe expanding in space-time, but also that this expansion is accelerating. Since there was no explanation to why this is happening, they proposed the concept of dark energy, a form of energy that makes up about 75 percent of the mass of the u... |

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... |

A comparison between supernova explosions taking place today and those that occurred early in the life of the universe reveals that the latter appear to age slower, as if time was warped somehow. It may look as counterintuitive or even impossible to some of us, but in fact, this is confirmed by the inflation theory, ... |

Geza Dyuk, the director of Astronomy at the Adler Planetarium, says that the universe is indeed expanding. Incredibly, even the great German physicist Albert Einstein didn't know for certain if the universe was expanding or contracting, at the time when he published his Theory of Relativity back in 1905. So, whi... |

Even today, most of the scientific communities still believe that the universe might have originated in a Big Bang explosion, but have no way to prove such process ever took place. Furthermore, although singularity-like objects are allowed to exist in the fabric of space-time, models explaining how such structures c... |

What is the dark matter? I don't know; in fact, nobody knows for certain what it is. However, we do know two basic facts: we proved that it does exist, and without it the galaxies would mostly fall apart. Nevertheless, it is extremely hard to create a complete image of the past and future of the universe, when y... |

Current theories about the beginning of the universe predict that all the observed matter originated in a single point in space, a singularity, which suddenly expanded in space-time provoking the so-called Big Bang. The light emitted by the glowing matter in the beginning of the universe slowly shifted towards the in... |

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... |
