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.
Physicists are more like avant-garde composers, willing to bend traditional rules... Mathematicians are more like classical composers.
All you are is a bag of particles acting out the laws of physics. That to me is pretty clear.

All of a sudden, space isn't friendly. All of a sudden, it's a place where people can die. . . . Many more people are going to die. But we can't explore space if the requirement is that there be no casualties; we can't do anything if the requirement is that there be no casualties.
You have to know evolution to understand the natural world. And that cannot be a threat to people of faith. There's a serious problem if you are forced by your faith to reject the most well-supported theory in all of science.
This [climate change] is potentially so dangerous that we have to act strongly. Do we want to play Russian roulette with two bullets or one?
Light is the only connection we have with the Universe beyond our solar system, and the only connection our ancestors had with anything beyond Earth. Follow the light and we can journey from the confines of our planet to other worlds that orbit the Sun without ever dreaming of spacecraft. To look up is to look back in time, because the ancient beams of light are messengers from the Universe's distant past.
The fact that you can remember yesterday but not tomorrow is because of entropy. The fact that you're always born young and then you grow older, and not the other way around like Benjamin Button - it's all because of entropy. So I think that entropy is underappreciated as something that has a crucial role in how we go through life.
It's not unexpected that shooting massive amounts of water, sand, and chemicals at high pressure into the earth to shatter shale and release natural gas might shake things up. But earthquakes aren't the worst problem with fracking.
