The Big Bang is a cosmological model in which the universe has been expanding for around 13.7 billion years, starting from a tremendously dense and hot state, thought to be the best model for the origin and evolution of the universe. But what happened before the Big Bang? If something did happen, that caused the Uni... |

The Big Bang is a cosmological model in which the universe has been expanding for around 13.7 billion years, starting from a tremendously dense and hot state, thought to be the best model for the origin and evolution of the universe. But what happened before the Big Bang? A logical thinking would produce the obvious... |

The term Big Bang nucleosynthesis refers to the creation of the first nuclei during the early phases of the universe, shortly after the Big Bang. It is generally believed that in the minutes and hours after the Big Bang itself, besides the normal hydrogen, the heavier isotopes deuterium (D) and tritium (T) and the l... |

It seems physicists around the world are predicting a grim future for our heirs who will want to learn more about space. Presuming that the human race will not survive for a few hundred or thousands of millions of years, it will be impossible for other beings to observe the Universe the way we do it now, from our ga... |

A theoretical physicist is stating that a second dimension of time could help physicists better explain the laws of nature. Now, the dimension of time has an important role in describing matter, gravity and other forces of nature, but something doesn't fit.Einstein's theory of general relativity and the eq... |

The fine-structure constant or Sommerfeld fine-structure constant, usually denoted is the fundamental physical constant characterizing the strength of the electromagnetic interaction. It is a dimensionless quantity, and thus its numerical value is independent of the system of units used.Using relic radiation from th... |
