Perhaps one of the most famous equations in the world, in all scientific fields, is Albert Einstein's theory of relativity, E=mc2. This means that the energy is equal to the mass multiplied by the square speed of light. Recently, an international team whose members come from Germany, France and Hungary, led by L... |

The most complex satellite ever built was almost compromised by an extremely tiny flaw in its design, which made the results very hard to read and less precise than needed. The Gravity Probe B, as the device was called, was launched in 2004 with the goal of proving some aspects of Einstein's general theory of re... |

Gravity Probe B is a NASA satellite currently in Earth's orbit, originally designed to measure relativistic effects predicted by Einstein's General Relativity Theory, such as frame dragging and the geodetic effect. It was launched in 2004 and relies on two high-precision gyroscopes to measure the two effect... |

In August 2002, the Laser Interferometer Gravitational-wave Observatory, or LIGO, became operational and started looking for the elusive gravitational waves predicted by Albert Einstein. It collected a massive amount of data, probably including some gravitational waves, however when scientists were put to the dauntin... |

"Leave your telescopes at home, we won't need them for the next observation," would probably say Einstein. Indeed, the universe is dominated on the large scale by this mysterious force we call gravity, but it is not only responsible for keeping the universe from falling apart. Gravitational lensing, for example,... |

So I've heard... But what does that even mean? It all goes back to German physicist Albert Einstein, who formulated the theories of Special and General Relativity in the early 1900s, in order to construct a better model that would explain the unique characteristics of space and time. Thus, relativity means that ... |

It may look like the stars live for ever and never change position in the sky or even that planets have extremely precise orbits, but the truth is anything but that. That's the reason why a team of astronomers from the St Mary University in Canada are proposing a redefinition of the astronomical unit. The scient... |

Fictitious forces, or pseudo forces are, as their name suggests, apparent forces that exert their influence on every object that has a mass in a rotating reference system. The fact that we are living in such a system, the Earth, means that we are influenced by these forces every day.The first weird thing about these... |

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... |

NASA is becoming more and more interested in future scientific applications based on the Moon. The agency asked the US National Research Council (NRC) in 2006 to advise it on what kinds of science could be tackled from the Moon and what projects should be given top priority.They liked the idea of an American astrono... |

It may sound strange, but Newton's theory of gravity predicts that it would be possible for three planets with equal masses to race around one another in a strange looking orbit the shape of figure 8. Einstein's more accurate theory of gravity, general relativity, was not sure to support such a weird orbit... |

Could it really be that a rapidly oscillating molecule is capable of slowing down its fall in a gravitational field, much like skydivers that increase the area of body parallel to the Earth to glide on the air current? Einstein's theory of general relativity states that the presence of matter in huge amounts (... |

The new precision tool with a variety of applications will serve to test Einstein's Theory of Relativity, and it's called atom interferometry. Interferometry is the science and technique of superposing (interfering) two or more waves, which creates an output wave different from the input waves, which in tu... |

Albert Einstein' general Theory of Relativity, published in 1915/16, unified special relativity and Newton's law of universal gravitation with the insight that gravitation is not due to a force but rather is a manifestation of curved space and time, with this curvature being produced by the mass-energy and... |
