   [Note 3] According to the special theory of relativity, c is the upper limit for the speed at which conventional matter or energy (and thus any signal carrying information) can travel through space. [4] [5] [6] All forms of electromagnetic radiation, including visible light, travel at the speed of light. For many practical purposes, light and ...

   The speed of light is 299,792,458 m/s in a vacuum. The speed of light in mph is 670,616,629 mph. With this speed, one can go around the globe more than 400,000 times in a minute! One thing to note is that the speed of light slows down when it goes through different mediums. Light travels faster in air than in water, for instance.

   How fast does light travel through space?

   • Light travels through the vacuum of space at 186,828 miles per second as transverse waves, outside of any material or medium, because photons—the particles that make up light—also behave as waves. This is referred to as the wave-particle duality of light. What Is Light?

   Why does light travel so fast?

   • Ergo, light is made of electromagnetic waves and it travels at that speed, because that is exactly how quickly waves of electricity and magnetism travel through space. And this was all well and good until Einstein came along a few decades later and realized that the speed of light had nothing to do with light at all.
