I am interested in fundamental particles and forces - with special interest in how light actually travels.
How Does Light Actually Travel?
- Thread starter JimLub

In summary, light travels as a wave, moving through space at a constant speed of 299,792,458 meters per second. It can also behave as a particle, known as a photon. Light travels in a straight line until it encounters an obstacle or changes medium, where it can reflect, refract, or be absorbed. The phenomenon of light traveling is explained by the theory of electromagnetism, which states that light is an electromagnetic wave consisting of oscillating electric and magnetic fields. The speed of light is a fundamental constant in the universe and plays a crucial role in many scientific phenomena.
