Waves in 5 dimensions-How?

  1. Sep 26, 2005 #1
    If our space was imbedded in a higher dimensional space with an additional orthogonal space dimension, and a sound wave traveled with a wavefront perpendicular to this additional dimension, what would we experience?
    What could we measure?
    Thanks, Ron

    NOTHING IS THE ANSWER. Our experiences & measurements is confined to our four Dimensional world. Of course, you can solve almost all equations of physics in "467 dimensional world"! (if you are good in math).But, that is a mathematical word and it is not our observed 4D world.

    I read something a while back that basically stated it is mathematically possible to define the laws of physics in any number of any type of the dimension we experience (space and time). The reason that we do not is basically Occam's razor. This is part of the issues with string theory for instance, at this point they are just math.

    YOUR FIRST SENTENCE IS RIGHT,IF AND ONLY IF, YOU CHANGE "WE EXPERIENCE" TO "WE WISH".HAVE YOU READ POST #2?
    IT IS TRUE THAT WE ONLY EXPERIENCE A 4D WORLD. BUT,DOES THIS MEAN THAT OUR UNIVERSE "IS" FOUR DIMENSIONAL? CERTAINLY IT DOES NOT.SO ADDING MORE DIMENSIONS TO THE EXISTING FOUR DOES NOT VIOLATE Occam's razor PRINCIPLE. OF COURSE ONE HAS TO GIVE A PHYSICAL MEANING TO THE EXTRA DIMENSION.
