My best teachers were not the ones who knew all the answers, but those who were deeply excited by questions they couldn't answer.

Very much, string theory is simply a work in progress. What we are inching toward every day are predictions that within the realm of current technology we hope to test. It's not like we're working on a theory that is permanently beyond experiment. That would be philosophy.
Interpretation
String theory is an evolving idea in physics that aims to be testable with current technology.
In this quote, Brian Greene emphasizes that string theory, while still developing, is grounded in scientific inquiry that aspires to yield experimental predictions. He contrasts it with philosophical theories, suggesting that scientific theories like string theory should ultimately be subject to empirical testing, reflecting the dynamic nature of scientific exploration.
In practice
In a lecture on scientific advancements where theories are discussed.
My best teachers were not the ones who knew all the answers, but those who were deeply excited by questions they couldn't answer.
All mathematics is is a language that is well tuned, finely honed, to describe patterns; be it patterns in a star, which has five points that are regularly arranged, be it patterns in numbers like 2, 4, 6, 8, 10 that follow very regular progression.
According to inflation, the more than 100 billion galaxies, sparkling throughout space like heavenly diamonds, are nothing but quantum mechanics writ large across the sky. To me, this realization is one of the greatest wonders of the modern scientific age.
So: if you buy the notion that reality consists of the things in your freeze-frame mental image right now, and if you agree that your now is no more valid than the now of someone located far away in space who can move freely, then reality encompasses all of the events in spacetime.
Black holes, we all know, are these regions where if an object falls in, it can't get out, but the puzzle that many struggled with over the decades is, what happens to the information that an object contains when it falls into a black hole. Is it simply lost?
Physicists are more like avant-garde composers, willing to bend traditional rules... Mathematicians are more like classical composers.
Science is the tool of the Western mind and with it more doors can be opened than with bare hands.
We send messages all the time, free of charge. There's a big shell out there now, 80 light-years around us. A civilization only a little more advanced than we are can pick those things up.
We've been modifying the biological world at the level of DNA for thousands of years. Somehow there is this new fear of what we already have been doing and that fear has limited our ability to provide real solutions.
There cannot be a language more universal and more simple, more free from errors and obscurities...more worthy to express the invariable relations of all natural things [than mathematics]. [It interprets] all phenomena by the same language, as if to attest the unity and simplicity of the plan of the universe, and to make still more evident that unchangeable order which presides over all natural causes
Scientists are people of very dissimilar temperaments doing different things in very different ways. Among scientists are collectors, classifiers and compulsive tidiers-up; many are detectives by temperament and many are explorers; some are artists and others artisans. There are poet-scientists and philosopher-scientists and even a few mystics.
But nature did not deem it her business to make the discovery of her laws easy for us.
