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.
Many people and governments share the mistaken belief that science, with new, ingenious devices and techniques, can rescue us from the troubles we face without our having to mend our ways and change our patterns of activity. This is not so.
Disease is not something personal and special, but only a manifestation of life under modified conditions, operating according to the same laws as apply to the living body at all times, from the first moment until death.
The faster you go, the shorter you are.
If there is any kind of animal which is female and has no male separate from it, it is possible that this may generate a young one from itself. No instance of this worthy of any credit has been observed up to the present at any rate, but one case in the class of fishes makes us hesitate. No male of the so-called erythrinus has ever yet been seen, but females, and specimens full of roe, have been seen. Of this, however, we have as yet no proof worthy of credit.
One general law, leading to the advancement of all organic beings, namely, multiply, vary, let the strongest live and the weakest die.
The study and knowledge of the universe would somehow be lame and defective were no practical results to follow.
