## What is the fastest thing we can see?

The human eye doesn’t really have a “maximum” speed it can see, but has a “timeframe” it can see. We can see light which is the fastest speed, but only if it is around for a certain amount of time. We can see comets traveling at hundreds of thousands of kilometres an hour for instance.
