Also, any potential explosion can only affect loaded chunks. What you could do, though, is make a command block to spawn a grid of strength-8 ignited orc bombs over the world, and then have another one always running after the previous one - this one would teleport you to where the last bomb was spawned, so that it could explode... This'd take forever, but would destroy a world.
