Simulating the Whole Universe

Roland Piquepaille writes "An international group of cosmologists, the Virgo Consortium, has realized the first simulation of the entire universe, starting 380,000 years after the Big Bang and going up to now. In 'Computing the Cosmos,' IEEE Spectrum writes that the scientists used a 4.2 teraflops system at the Max Planck Society's Computing Center in Garching, Germany, to do the computations. The whole universe was simulated by ten billion particles, each having a mass a billion times that of our sun. As it was necessary to compute the gravitational interactions between each of the ten billion mass points and all the others, a task that needed 60,000 years, the computer scientists devised a couple of tricks to reduce the amount of computations. And in June 2004, the first simulation of our universe was completed. The resulting data, which represents about 20 terabytes, will be available to everyone in the months to come, at least to people with a high-bandwidth connection. Read more here about the computing aspects of the simulation, but if you're interested by cosmology, the long original article is a must-read."

    Hello. I am really sorry that this message is off-topic. But I'm in a desperate situation, in a dire need of your help. I am aware a lot of intelligent IT people read this forum.

    My problem is - I have come up with an idea that will be a revolutionary solution concerning car theft. I have created a device that will drop car theft to zero (0%) percent. With this device installed it is virtually impossible to steal the car. How can I make sure no one can steal my idea? Who should I contact regarding this device I have invented?

    Thank you very much for your help!

    Why can't the editors either read the fucking article (crappy blog entry) to see if there's any meat, or perhaps even ignore the idiot itself?
