We only have to look at ourselves to see how intelligent life might develop into something we wouldn't want to meet.
The Planck satellite may detect the imprint of the gravitational waves predicted by inflation. This would be quantum gravity written across the sky.
Interpretation
What this quote means
The quote discusses the potential detection of gravitational waves by the Planck satellite, suggesting a deep connection between quantum gravity and the cosmos.
In this quote, Stephen Hawking highlights the groundbreaking possibility that the Planck satellite could observe the remnants of gravitational waves, which were theorized to arise during the rapid expansion of the universe known as inflation. This signifies a profound intersection of quantum gravity and cosmological observations, suggesting that the principles of quantum physics may manifest visibly across the universe, fundamentally enhancing our understanding of the cosmos.

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.

Every mode of transport that we use - whether it's planes, trains, automobiles, bikes, horses - is reusable, but not rockets. So we must solve this problem in order to become a space-faring civilization.
In the history of science it has often happened that the majority was wrong and refused to listen to a minority that later turned out to be right.
Enormous numbers of people are taken in, or at least beguiled and fascinated, by what seems to me to be unbelievable hocum, and relatively few are concerned with or thrilled by the astounding-yet true-facts of science, as put forth in the pages of, say, Scientific American.
The Earth is not 6,000 or 10,000 years old. It's not. And if that conflicts with your beliefs, I strongly feel you should question your beliefs.
