[Warhammer 40K] Why hasn't the Imperium changed significantly in the past 10,000 years?

The Imperium of Man seems basically stagnant. Why hasn't it had any major changes of government in that time? 10,000 years is a really long time.

You could blame religion, except that on Earth historically, religions aren't that static either. New religions pop up and old ones reform, splinter into sects, and so on.

Is there some particular force holding the Empire static for such a long time?

It's hard to notice the changes on a large scale. Sometimes a world will develop some new and fascinating philosophical outlook on life or some revolutionary technology or what have you. And maybe they share it with the larger imperium only to realize they're caught in a warp disturbance and isolated for millennia or maybe they get executed for heresy or just maybe they can't get anyone to understand their dialect of low gothic. And other places it's just that the fundamental ideas of how things work are completely lost to humanity. They're cavemen that know banging the shiny rock on a the black rock makes fire not that flint and granite are two different types of stone and why they interact they way they do.


These are the guys that can deploy a nuke but wouldn't know how to program a clock in most cases.
