Intriguing New Equations Show a "Phased" Creation Our own universe does not seem to have come into existence this way. The phase-transition model is not meant to replace the theory of the Big Bang. “Today, cosmologists know a lot about the early universe – we are not challenging their findings. But we are interested in the question, which phase transitions are possible for time and space and how the mathematical structure of spacetime can be described†Astronomers combine mathematical models with observations to develop workable theories of how the Universe came to be. The mathematical underpinnings of the Big Bang theory include Albert Einstein's general theory of relativity along with standard theories of fundamental particles. Today NASA spacecraft such as the Hubble Space Telescope and the Spitzer Space Telescope continue Edwin Hubble's work of measuring the expansion of the Universe. One of the goals has long been to decide whether the Universe will expand forever, or whether it will someday stop, turn around, and collapse in a "Big Crunch?" rOZZ Music Pictures |

As technology has evolved, astronomers are able to look back in time to the moments just after the Big Bang. This might seem to imply that the entire universe lies within our view. But the size of the universe depends on a number of things, including its shape and expansion. Just how big is the universe? The truth is, scientists can't put a number on it. http://www.space.com/24073-how-big-is-the-universe.html |

But the size of the universe depends on a number of things, including its shape and expansion. Just how big is the universe? The truth is, scientists can't put a number on it. I read some time ago that scientists have used the WMAP data to essentially draw triangles as big as possible. They then measure the angles of the triangles to see if they add up to 180 degrees or not. Triangles with angles measuring 180 degrees are flat and therefore the universe is infinite. If not then the universe will be curved. So far the triangles measured are within 3 decimal places of 180 degrees so they said the universe is infinite. Cannot find the original article, sorry. |

This article could shed some light on the matter. http://imagine.gsfc.nasa.gov/docs/features/exhibit/map_shape.html [edit]The quest to understand the precise geometry and shape of our universe began thousands of years ago, when mathematicians and astronomers used mathematical models to try and explain their observations. While there seem to be some irregularities in the WMAP data that throw the conflicting analyses and conclusions into doubt, there is hope that the data from the Planck satellite will ultimately lead us to the answer. Even if it does not, we will continue to develop new models and methods so that one day we can determine the shape of the Universe. rOZZ Music Pictures |

Those formulas are just too much for me... You have to start with the easy stuff like e^{i \pi} + 1 = 0 |

Those formulas are just too much for me... Euler's identity... [edit]Makes me think of the gelijkheids formule in Dutch, couldn't quite find the English equivalent. I guess you could call it the equality formula. [edit2]darn maths!!!! rOZZ Music Pictures |

I used to ride my bicyle past that antenna at lunch when I worked for Bell Labs. It really isn't that big--maybe 12 feet high or so. Made out of what just looked like galvanized sheet metal. |

The universe can simply be thought of as a giant globe that is infinite in size in all directions. All this stuff about curved planes and warping space time is just scientists trying to explain what they don't understand, and formulas that don't work unless they have the missing item X. That's it! Thanx Chris:) (gelijkheid van Parseval...) rOZZ Music Pictures |

The universe, as most of us know it now, indeed started with a 'big bang'. That was God making the whole shebang, kids. He liked fireworks too. There was no other show quite like that one, and although in our infancy, we were not quite able to appreciate it, we can, with a bit of research, detect it now. All part of the amazing universe that we now inhabit. Kaboom, kitties. Kaboom. "Time is simply the mechanism that keeps everything from happening all at once." |

Earthlings may be extreme latecomers to a universe full of life, with alien microbes possibly teeming on exoplanets beginning just 15 million years after the Big Bang, new research suggests.

Welcome Julie :) I don't think anyone of these theories makes sense. Mother Nature's, secrets may never be known. |

New research suggests that black holes, formed from the first stars in our universe, heated the gas throughout space later than previously thought. @ Chris ;)) Interesting though: Black holes also imprinted a clear signature in radio waves which astronomers can now search for. The study is a major new finding about the origins of the universe. rOZZ Music Pictures |

Black holes at the beginning of the Big Bang should have emitted very long wavelength gravitational waves, which are the target of the LISA mission, should it be financed and launched. Tullio |
