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

There may be many Big Bangs that happened at various and far-flung locations, each creating its own swelling, spatial expanse, each creating a universe - our universe being the result of only one of those Big Bangs.
Interpretation
The quote suggests that our universe is just one of potentially many created by separate Big Bang events.
Brian Greene's quote reflects on the concept of multiple universes, proposing that the Big Bang which gave rise to our universe may not be unique. This idea opens up discussions about the vast possibilities of existence in the cosmos, indicating that cosmic events may occur in multiple locations, each causing the formation of individual universes, leading to a broader understanding of reality beyond our observable universe.
In practice
During a lecture on cosmology, one could use this quote to illustrate the concept of multiple universes.

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.
Nobody ever told us all matter radiated. We just assumed it did.
I always felt that a scientist owes the world only one thing, and that is the truth as he sees it. If the truth contradicts deeply held beliefs, that is too bad. Tact and diplomacy are fine in international relations, in politics, perhaps even in business; in science only one thing matters, and that is the facts.
I came to dedicate my life to opening space to the average person and crafting designs for new spaceships that could take us far from home. But since Apollo ended, such travels were only in our collective memory.
Our job is not to predict the future. Rather, it's to suggest all the possible futures - so that society can make informed decisions about where we want to go.
The outcome of any serious research can only be to make two questions grow where only one grew before.
Physics filled me with awe, put me in touch with a sense of original causes. Physics brought me closer to God. That feeling stayed with me throughout my years in science. Whenever one of my students came to me with a scientific project, I asked only one question, 'Will it bring you nearer to God?'
