Relativistic speeds
We thing the speed of light is fast. But it really isn't when put into a meaningful context. For all mundane purposes it's other instantaneous or just doesn't matter at all.
By absolute comparison the speed of light is much, much faster than for example the speed of sound. But for us the speed of sound is actually really fast. Fast in a sense we can still easily comprehend. Fast in a sense that we can actually for example travel at that speed, and beyond. Even though only a small number of people have actually done so.
