We only have to look at ourselves to see how intelligent life might develop into something we wouldn't want to meet.

There are no black holes - in the sense of regimes from which light can't escape to infinity. There are however apparent horizons which persist for a period of time.
Interpretation
This quote challenges the traditional concept of black holes, suggesting that while they may seem impenetrable, light can still escape from them over time.
Stephen Hawking's quote reflects on the nature of black holes, proposing that they do not exist as absolute voids from which light cannot escape. Instead, he introduces the idea of apparent horizons that can be temporary, emphasizing the complexity and dynamism of such cosmic phenomena and encouraging a deeper understanding of the universe's mysteries.
In practice
During a lecture on astrophysics, one might use this quote to illustrate the complexities of black holes.
We only have to look at ourselves to see how intelligent life might develop into something we wouldn't want to meet.
I regard the brain as a computer which will stop working when its components fail. There is no heaven or afterlife for broken down computers; that is a fairy story for people afraid of the dark.
It surprises me how disinterested we are today about things like physics, space, the universe and philosophy of our existence, our purpose, our final destination. Its a crazy world out there. Be curious.
I was not a good student. I did not spend much time at college; I was too busy enjoying myself.
The world has changed far more in the past 100 years than in any other century in history. The reason is not political or economic but technological-technologies that flowed directly from advances in basic science. Clearly, no scientist better represents those advances than Albert Einstein: TIME's Person of the Century.
In my opinion, there is no aspect of reality beyond the reach of the human mind.
First, it is necessary to study the facts, to multiply the number of observations, and then later to search for formulas that connect them so as thus to discern the particular laws governing a certain class of phenomena. In general, it is not until after these particular laws have been established that one can expect to discover and articulate the more general laws that complete theories by bringing a multitude of apparently very diverse phenomena together under a single governing principle.
Most man only care for science so far as they get a living by it, and that they worship even error when it affords them a subsistence.
I venture to define science as a series of interconnected concepts and conceptual schemes arising from experiment and observation and fruitful of further experiments and observations. The test of a scientific theory is, I suggest, its fruitfulness.
Challenges in medicine are moving from 'Treat the symptoms after the house is on fire' to 'Can we preserve the house intact?'
The universe is a symphony of strings, and the mind of God that Einstein eloquently wrote about for thirty years would be cosmic music resonating through eleven-dimensional hyper space.
We're going to need a definitive quantum theory of gravity, which is part of a grand unified theory - it's the main missing piece.
