Hi I'm a confused layman, and was hoping to get some answers to the question: why is the speed of light? That's not a typo - I mean, why is it what it is? The questions below are specific ways to ask essentially the same question. 1. The speed of light is 299,792,458 metres per second. What stops it from reaching 299,792,459 m/s? 2. If light has no mass, what stops it from having infinite speed? What’s slowing it down? 3. Light from the sun takes 8 minutes 24 seconds to reach the earth – why can’t it get here faster? Thanks in advance. .
