Describing Matter: Physical and Energy-Filled
ОглавлениеEinstein helped to revolutionize our ideas about the composition of matter as much as he changed our understanding of space, time, and gravity. Thanks to Einstein, scientists realize that mass — and therefore matter itself — is a form of energy. This realization is at the heart of modern physics. Because gravity is an interaction between objects made up of matter, understanding matter is crucial to understanding why physicists need a theory of quantum gravity.
