Destructive brain theory

Even though everybody would be giant brain floating in space time, it doesnt mean they will coexist. The brains are just future humans with the same emotions and feelings which means the primal war-like instincts. There will be one huge destructive brain war which will involve much destruction with mental brain nukes. It would look awesome, but will have devastating effects on space assuming that all matter in the universe is destroyed.

The brains also have nuclear brain mental shields, like force fields. The battle for the universe or multiverse will probably rage on.

More on the multiverse later. There is a chance that we live on a huge brane inside a higher dimensional space. This theory is M-theory

Mental brain power, do you have the brain?
Imagine your brain was extra powerful.
