The electromagnetic, weak and strong forces, trapped within the 3-D brane, are not aware of the extra dimension and so maintain their usual behaviour. Gravity, on the other hand, behaves rather differently. If we approach a massive body closer than a distance L, we would feel the effects of a force law in four spatial dimensions rather than three. In this case, the gravitons from the massive body are spread over a 4-D sphere with radius r, the surface area of which grows as r3. We would then find that the gravitational force follows a 1/r3 law.
However, as we move further away from the body (i.e. r > L) the usual 1/r2 behaviour is restored. The reason for this is as follows. Adding a compactified extra dimension is rather like standing between two mirrors; we see images of ourselves stretching to infinity.

| i think its kinda like when u look @ something through a magnifine glass really close, then as you move back it flips. Other Dimensions have that affect with gravity. |

Ants + magnified glass = fun times:wtf: |

| Gravity is some crazy ...probably, the most complicated thing in science, since it is the only thing that we know of that is affected by more then 4 dimensions. Light(electromagnetic wave) is limited to 4. |

sorry what exactly is 4-D? i'm guessing u're talking physics-related stuff? |

kinda, but nothing 2 complicated...its basically just time... You can hold a 3/d object HxWxD...but if that is moving faster/slower then "light," it acts as a different dimension, since things change as time goes by. So if you can change the time you are in, you are moving in a different dimension.
its kinda like HxWxD taken @ 12:00(a time)... |

that is freaky! anyways, yes bwainnn, it was a rockin time when i used to play with my ant kit back in the days...lol now i'am scared of them :S
cheers

| since light really only operates @ 3 dimensions HxWxD, since light is "time." you wouldnt be able to see another dimension. But you could be affected by its gravity. |

| for instance if there was a sphere/black hole...something like that, and it was a meter away from you...imagine something the size of a baseball... You wondn't be able to see this since light doesnt travel in it. But you could theoretically, be gravitationaly attracted to it. The gravity could even bend light if it was strong enough. That would lead to HxWxDxDistance from that object and the time it was at...but that is only if its a closed dimension, with a specific volume. |
