Matter in Our Surroundings
Is a shadow made of the same stuff as a bucket of water? To find out, we have to look closely at what actually makes up our universe.
Scientists define matter by two simple rules. It must have mass, and it must occupy space, which we call volume.
So, while water has mass and takes up space, light and shadows do not. They are forms of energy, not matter.
