brane theory

I am not to familiar with the membrane theory brane for short, i just read an article about it in discover magazine. Apparently string theory predicts that our universe is a large 3 demensional brane right next to another universe across another spacial demension. Every trillion or so years our two universes collide releasing all the energy stored up in ever cubic centimeter of space resetting all the order elminating the need for a point of creation. Any one have any more to add?
