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 idea that there could be other universes out there is really one that stretches the mind in a great way.
Interpretation
The concept of multiple universes challenges our understanding and encourages creative thinking.
Brian Greene's quote speaks to the expansive possibilities of existence beyond our own universe. It highlights how contemplating the existence of other universes can push the boundaries of human thought and imagination, inviting us to explore ideas that may seem far-fetched or difficult to comprehend.
In practice
During a lecture on theoretical physics, I quoted Brian Greene to inspire students to think beyond traditional boundaries.

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.
In no other branch of mathematics is it so easy for experts to blunder as in probability theory.
If we want to travel into the future, we just need to go fast. Really fast. And I think the only way we're ever likely to do that is by going into space.
I'm on a crusade to get movie directors to get their science right because, more often than they believe, the science is more extraordinary than anything they can invent.
The feeling is constantly growing on me that I had been the first to hear the greeting of one planet to another.
'Goals' and 'caps' on carbon emissions are practically worthless, if coal emissions continue, because of the exceedingly long lifetime of carbon dioxide in the air.
Theories are like a stairway; by climbing, science widens its horizon more and more, because theories embody and necessarily include proportionately more facts as they advance.
