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.
We didn't build the interstate system to connect New York to Los Angeles because the West Coast was a priority. No, we webbed the highways so people can go to multiple places and invent ways of doing things not thought of by the persons building the roads.
If the Earth gets hit by an asteroid, it's game over. It's control-alt-delete for civilization.
Certainly I see the scientific view of the world as incompatible with religion, but that is not what is interesting about it. It is also incompatible with magic, but that also is not worth stressing. What is interesting about the scientific world view is that it is true, inspiring, remarkable and that it unites a whole lot of phenomena under a single heading.
My roots, in college, were in behavior in the context of evolution.
There are living systems; there is no living "matter." No substance, no single molecule, extracted and isolated from a living being possess, of its own, the aforementioned paradoxical properties. They are present in living systems only; that is to say, nowhere below the level of the cell.
A study of Disease-of Pestilences methodically prepared and deliberately launched upon man and beast-is certainly being pursue in the laboratories of more than one great country. Blight to destroy crops, Anthrax to slay horses and cattle, Plague to poison not armies but whole districts - such are the lines along which military science is remorselessly advancing.
