Research in physics involves the study of matter, energy, and the fundamental forces of nature. Physicists conduct experiments and develop theories to understand how the universe works, from the smallest particles to the largest galaxies. This research can lead to new technologies and insights into the laws governing the physical world. Key areas of research include quantum mechanics, which explores the behavior of particles at the atomic level, and relativity, which examines the effects of gravity and the curvature of space-time. Notable physicists like Albert Einstein and Niels Bohr have made significant contributions that continue to influence modern physics today.
