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

Relativity challenges your basic intuitions that you've built up from everyday experience. It says your experience of time is not what you think it is, that time is malleable. Your experience of space is not what you think it is; it can stretch and shrink.
Interpretation
What this quote means
This quote emphasizes that our intuitive understanding of time and space is fundamentally challenged by the principles of relativity.
Brian Greene's quote highlights how the theory of relativity fundamentally alters our perceptions of time and space, suggesting that both are not fixed realities but rather flexible constructs influenced by conditions such as speed and gravity. It invites us to reconsider our everyday experiences and intuitions, revealing that what we often take for granted about the universe is, in fact, far more complex than it appears.

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.

The fundamentalists deny that evolution has taken place; they deny that the earth and the universe as a whole are more than a few thousand years old, and so on. There is ample scientific evidence that the fundamentalists are wrong in these matters, and that their notions of cosmogony have about as much basis in fact as the Tooth Fairy has.
