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 central idea of string theory is quite straightforward. If you examine any piece of matter ever more finely, at first you'll find molecules, atoms, sub-atomic particles. Probe the smaller particles, you'll find something else, a tiny vibrating filament of energy, a little tiny vibrating string.
Interpretation
What this quote means
String theory suggests that at the fundamental level, all matter is composed of tiny vibrating strings of energy.
In this quote, Brian Greene explains the essence of string theory, which posits that the universe's most basic components are not particles but rather tiny vibrating strings. This perspective shifts our understanding of matter and energy, illustrating a deeper connection between the physical elements of the universe and their fundamental vibrating nature.

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.
