More than 99.9% of the world is simply empty space, emptiness between the electrons and the nucleus of the atom. Most modern people know this, it's basic. Behind the veil of Maya there is nothing.
The world is an illusion. Without brains there wouldn't be any reality, practically.
There wouldn't be any bad weather or lovely weather, no funny cloud formations, no chirping sparrows, no noisy neighbors with power tools, no nothing.
