Brian Greene: "If space and time did not behave this way, the speed of light would not be constant and would depend on the observer's state of motion. But it is constant; space and time do behave this way. Space and time adjust themselves in an exactly compensating manner so that observations of light's speed yield the same result, regardless of the observer's velocity." http://www.pbs.org/wgbh/nova/physics/special-relativity-nutshell.html

First of all, as the speed of your spacecraft increases, the length of everything - you, your measuring devices, your spacecraft - shortens in the direction of motion, as seen by everyone else. Furthermore, your own time slows down exactly enough so that when you haul out your newly shortened yardstick, you are guaranteed to be duped into measuring the same old constant value for the speed of light. What we have here is a COSMIC CONSPIRACY OF THE HIGHEST ORDER." https://www.amazon.com/Death-Black-Hole-Cosmic-Quandaries/dp/039335038X

All correct, for once. (apart from the all caps)

Maybe you should limit yourself to quoting people who know better,
instead of trying to write things for yourself,

No he didn't. Your misquoting Einstein is not worthy of further
discussion.

For this to be true, space and time had to be combined into a single
framework that conspired to keep light's speed the same for all
observers." https://www.livescience.com/space-time.html
