    esp,

    We don't really know what happens at the centre of a black hole in detail yet. So, I suppose, yes it is possible. But I won't bet my house on it.

    Ehhhhrrr... no, it's a scalar quantity.

    Bye!

    A scalar quantity, such as energy, has no "direction" in it. What you can do, is look at the energyflow, which is indeed a vector quantity (that indicates the direction where energy flows to). However, energyflow =/= energy.

    Bye!

    Interesting Theory

    Now thats an interesting theory. My answer has to be that I just don't know, but thinking about it - now thats negative energy!!

    I think that Negative Energy is misrepresented. Empty space has a lot of energy just existing. An area of Negative Energy is simply an area of space more spread out. Nearer the time of the big bang a volume of empty space had more energy. These days it's more spread out and so has relatively less energy, ie. it's value is less than that previously, relatively negative.

    How does this help? Just create an area of Negative Energy around your space craft and you will have to traverse less distance, for the same speed, to get to your destination.

    Effectively, yes, an area of less dense space has relatively less mass. Just like an area of more dense space has positive mass.

    ok, i just backspaced my big explanation of how to create negative energy cause I re-read the book I got the info from, and realized I would need to write ALOT more to even start to explain the whole process........and right now it's late and I'm too lazy to type,

    but I will tell you it's called the casimir effect that was predicted by hendrick casimir, I found it in the book "Time Machines", it's about the hiesenburg uncertainty principal allowing a temporary violation of conservation of energy to occur. look it up on google foir more info

    and if no one finds any info, I'll find a scanner and put up the pages from the book....
