asumming you could focus the laser at a point, make it stop after that point, and make the "blade" visible, how would you be able to use it like a sword? the "blades" would pass through each other.

[math]\nabla=\frac{{\partial}x-hat}{{\partial}x}+\frac{{\partial}y-hat}{{\partial}y}+\frac{{\partial}z-hat}{{\partial}z}[/math]? what are "x-hat", "y-hat", and "z-hat"?

what is the [math]\nabla[/math] vector?

Here is a related question I had a while back.

gravitons are virtual particles.

if you could warp space negatively in front of the vehicle and positively behind, it could travel faster than light relative to another object, but it would still be travelling subluminal relative to spacetime.

what? try rephrasing in english.

what's wrong with previewing the post?

"the founding fathers were all devout christians..."

not necesarily. you would need to make a graph. most of the time, [math]\lim{x{\to}a}f(x)=f(a)[/math]. that is one of the things needed for a function to be continuous over an interval. if f(a) exists and [math]\lim_{x{\to}a}f(x)=f(a)[/math] over a certain interval, then the function is continuous over said interval.

thanx for pointing out the typo. it is fixed now. yes, it tends to it, but it is infinitely close to it at infinity. can you actually get infinately far away from it? no. the whole idea of introducing the limit was to show that it does get smaller as you get farther.
