Web21 jan. 2024 · Light is fast! It can reach the universal speed limit — 186,000 miles per second. Why does light travel at 186 000 miles per second? That’s because all massless particles are able to travel at this speed, and since light is massless, it can travel at that speed. What is 1% the speed of light? WebI can't tell you why light travels so fast. I can tell you one interesting thing though. Albert Einstein showed that light is the fundemental speed limit in the universe. Nothing with mass can move as fast as light. Answer 2: This is an interesting question, one I have often wondered about.Light is a complicated phenomenon.

Some surfaces and materials reflect light really well. We call these reflective materials, and they can be very useful - for instance, wearing a hi-vis jacket while cycling in low-light will make you more visible.
Until the early modern period, it was not known whether light travelled instantaneously or at a very fast finite speed. The first extant recorded examination of this subject was in ancient Greece. The ancient Greeks, Arabic scholars, and classical European scientists long debated this until Rømer provided the first calculation of the speed of light.
