    is it possible to make a sun ?
    coz if we do , than we dont need things like fossil fuels to produce heat

    I think they call this "fusion." And yes, we are working on it (on a much smaller scale than the sun, naturally).

    any sucesses? on the trials ?
    i heard that they can make the reaction going for like
    1 mili second
    but does anyone know the process ? like.. how they actually do it ?
    all i know is that, it starts from hydrogen or some other element that is being heated up with really strong lasers, and it creates plasma or something
    need some opinions thanx

    I heard that they put a small sample of tritium and deuterium on something that looks like the tip of a pen, and then concentrate a lot of powerful lasers from all directions. This heats the atoms up and (almost) started the reaction. They couldn't contain the smaple long enough for it to be heated up enough, because the atoms(ions, I should say) repelled each other too strongly.
