My best teachers were not the ones who knew all the answers, but those who were deeply excited by questions they couldn't answer.
The funny thing is, I sometimes get the impression that some people outside of the field think that there's some element of security that we have in working on a theory that hasn't made any predictions that can be proven false. In a sense, we're working on something unfalsifiable.
Interpretation
What this quote means
The quote suggests that working on unfalsifiable theories provides a false sense of security to some individuals outside the field.
In this quote, Brian Greene points out the misconception held by some external observers regarding the nature of theoretical work in science. He articulates that unfalsifiable theories, which cannot be tested or proven wrong, offer an illusion of security, as they do not hold up to the rigorous scrutiny typical in scientific inquiry. This highlights the inherent challenges and complexities faced by scientists, as they navigate theories that may lack tangible evidence or predictability.

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.

There would seem to be nothing more obvious, more tangible and palpable than the present moment. And yet it eludes us completely. All the sadness of life lies in that fact. In the course of a single second, our senses of sight, of hearing, of smell, register (knowingly or not) a swarm of events and a parade of sensations and ideas passes through our head. Each instant represents a little universe, irrevocably forgotten in the next instant.
Something in the world forces us to think. This something is an object not of recognition but of a fundamental encounter.
