According to a study published in April 2011, it could be that primordial black holes, the first structures of their type in the Universe, were not produced after the Big Bang but, rather, before it. If proven, this idea could turn modern cosmology on its head.
Simply put, there is no way for something to have been... |

Since the Big Bang model established what happened at the beginning of the Universe with a fairly high degree of certainty, astronomers have been divided about how the entire thing will end. Some even say that it will not end at all.
Over the years, numerous proposals dealing with the upcoming end of the Universe h... |

A group of investigators at the University of Maryland, in the United States, announce that they were recently able to simulate the end of time. They say that the conditions they replicated are known to astronomers as the Big Crunch, or the final event to take place in the Universe.
What the scientists determined ... |

Analysis of the basic properties of black holes appears to indicate that some of these dark behemoths may be capable of surviving the destruction of the Universe. If the Cosmos operates in cycles of Big Bangs and Big Crunches, then black holes can theoretically endure the latter events. In a new study, experts look a... |

The Big Bang theory says that the universe began at T=0 as it suffered a sudden expansion into space-time, from a singularity-like object of zero volume but of infinite mass and density. So what was before that? Certainly, things do not just appear out of nowhere. Some kind of structure must have preceded the current... |

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... |

In August this year, astronomers studying the Cosmic Microwave Background Radiation or CMB, a 'remnant' of the Big Bang, discovered a texture of a giant cold spot in the universe, completely empty of any normal matter or dark matter and even any kind of radiation. In order to explain how such a void might h... |
