Godspeed is the speed of light. That is, it’s the fastest that anything can travel through space.
The speed of light has been defined as 299,792,458 meters per second since 1983. It’s one of the most fundamental constants of nature and has been so for thousands of years. It’s also known as c — it’s just a number that physicists use to describe how fast light travels in a vacuum.
A vacuum is essentially empty space with no matter particles floating around (like air). There are different kinds of vacuums — most people think about outer space when they hear “vacuum,” but there are also vacuums in laboratories on Earth where scientists study materials under extreme conditions like high pressures or low temperatures that might not occur naturally in nature.
Light travels at this speed regardless of what medium it travels through (air, glass, water, etc.).
