Einstein's Big Idea ain't big enough: Or why the Word trumpts all ideas

I've recorded PBS's "Einstein's Big Idea" and have been watching it over few days as I worked out but I found one thing interesting: pre-Einstein physics assumed that mass and energy (and time) were constant, but Einstein had a breakthrough in thinking that time didn't have to be constant. Yet there was one thing which was assumed to be constant: light. But now there are studies which cast doubt into the light being constant. If light is non-constant, then what?

There is also this long unfulfilled desire to find the Grand Unified Theory of everything in the universe....

It's funny how the matter has a similar story: atom was thought to be the smallest. Then we discovered subatomic particles and quantum mechanics. Can we say that we have now reached the bottom? Probably not.

What's really amazing is that we humans can make simple assumptions and turn them into breakthroughs for better understanding the universe we live in (but also surprised in not finding the "final" answer). And amidst of all the changes in theories and ideas, one thing is constant: (human) language and this semi-universal, yet rigorous subset of human language called mathematics. Yes the flavor of human language keeps changing (Greek, Latin, German, English, etc.) but the fundamental need for humans to describe the "new" ideas in language hasn't changed (and the power of each language is such that they can be translated from one to the other). The language of mathematics have allowed a more precise way to describe the universe without direct need for a human language, yet without the verbage, ideas expressed in the math cannot be understand by others reading just the math.

So, all the more reason to be in awe of the Word:
In the beginning was the Word, and the Word was with God, and the Word was God. John 1:1
