The theory is that our 3d space (or 4d space-time) is like a surface that exists in a universe with more dimensions. This is like how paper exists in our 3d but is itself 2d. In string theory these branes can hit each other and when this happens that energy is dissipated into the brane itself (like if you hit a metal sheet and it starts to ring, the kenetic energy has dissipated into vibrational energy in the sheet. One of these collision events would cause a big-bang in our 3d sheet in larger dimensional space.
