Here are two earlier threads. There are more. > [@Why is light used as the unique descriptor for the universal speed limit?](https://boards.straightdope.com/t/why-is-light-used-as-the-unique-descriptor-for-the-universal-speed-limit/615445): > > As per the Wikipedia entry for “Speed of Light”: [Speed of light - Wikipedia](http://en.wikipedia.org/wiki/Speed_of_light) Apparently the top speed of light is a much more general concept than the name alludes to, because this same top speed also applies to phenomena such as information and gravity (theoretically). Why is light so fundamental out of all of these phenomena that it deserves a monopoly on the name for the universal speed limit? > [@Does the speed of light limit apply to the universe as a whole?](https://boards.straightdope.com/t/does-the-speed-of-light-limit-apply-to-the-universe-as-a-whole/662298): > > Years ago I read an article (I think it was in Popular Science) that a group of scientists had discovered two objects were further apart in light years than the age of the universe and the angle of their divergence could account for. Is this theoretically possible? Could the fabric of space actually be expanding faster than the speed of light? --- _[View the full topic](https://boards.straightdope.com/t/yeah-but-why-is-c-the-speed-limit-of-the-universe/1008837)._
