I probably won't be able to ask this question as well as I envision it in my mind. So please bear with me and try and decipher my babbling gibberish as best you can. According to my very limited knowledge of Strings and Branes.......(theory) Strings are the smallest things in the Universe, and can sometimes stretch into membranes that basically are an entirely different universe. So are strings also the smallest things in those universes, and can sometimes stretch into Branes which are entirely different universes....etc...etc...etc...? So does this mean the "infinity" actually does exhist? If this makes any sense at all to you, please help as best as you feel like. Thanks a ton! Dan.
