How fast does light travel? The official speed of light has changed several times throughout history. After centuries of debate and experiments with different results, the scientific community finally settled the matter in 1983…maybe. To measure the speed of anything, you’ll need to know 2 things: the distance between point A and B, and the time it takes for an object to travel between those points. With distance divided by time, you’ll have yourself the speed of light.

But with every experiment done to measure light speed, there’s always been an extra cog in the wheel that everyone overlooked. Or rather brushed aside. And this is what we're going to talk about. But the truth is that the speed of light is the ultimate question among scientists, and so far, there’s just no way of truly measuring it. Unlike the speed of sound which is more conceivable, the speed of light might just be light-years ahead of us!
