Not only the electromagnetic radiation, even matter once set in motion in outer space, shall carry on moving forever. To stop this or change its state of motion external forces are necessary. This is Newton’s law of inertia, applicable to matter. In quantum state the difference between matter and wave becomes minimal or ceases to exist. Thus electromagnetic waves, light, heat and radio waves, starting from a star or galaxy travel for billions of years as tiny particles or photons. And shall go on traveling.
