Physicists think the world is made of atoms.
Biologists think the world is made of cells.
Musicians think the world is made of vibrations.
Painters think the world is made of lights.
Authors think the world is made of stories.
I pour my thoughts onto the world wide web.
And thats' the ones I can remember. There were possibly others, but my brain is at the moment a sponge holding too much. Later!
