Einstein’s theory of special relativity tells us that for a moving object, time passes more slowly than for a stationary ...

Scientists say fragments of energy may be the fundamental building blocks of the universe—not particles and waves.

Fragments of energy may be the fundamental building blocks of the universe. The theory combines the ideas of particles and waves into a concentration of energy that flows throughout space and time.
