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

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?
Interpretation
What this quote means
The quote discusses the mystery of information loss in black holes, a fundamental question in theoretical physics.
In this quote, Brian Greene highlights a significant and perplexing issue in astrophysics regarding black holes: when an object falls into a black hole, it is believed that the physical information about that object may not be recoverable. This raises profound questions about the nature of information, the fabric of reality, and the laws governing the universe, challenging our understanding of physics and prompting extensive debate among scientists.

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.

My whole interest is, how do you use evolution as an innovation engine? How does evolution solve new problems that life faces? And to have a system that can create a whole new chemical bond that biology hasn't done before, to me, demonstrates the power of nature to innovate.

My own field of paleontology has strongly challenged the Darwinian premise that life's major transformations can be explained by adding up, through the immensity of geological time, the successive tiny changes produced generation after generation by natural selection.

The fact of evolution is the backbone of biology, and biology is thus in the peculiar position of being a science founded on an improved theory, is it then a science or faith?

Darwin gives courage to the rest of science that we shall end up understanding literally everything, springing from almost nothing - a thought extremely hard to comprehend and believe.
