Trying to understand how strings and branes work

  1. Dec 3, 2009 #1

    I saw an interview with Dr. Michio Kaku on branes and when asked where these other universes (or is it ‘worlds’) on other branes exist, he said in your living room. (?) This doesn’t sound like the vertical wavy sheets nor the separate (or connected) bubbles we’re shown in brane videos.

    Are strings on ‘other’ branes thought to be physically within the same space that we are? That is to say, if we could look at the strings attached to our brane would we also see (if we could see) strings that are on other branes mixed in with them?

    If so… what is meant by ‘colliding branes’?

    Thanks any help!
