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

It now appears that the way the universe began can indeed be determined, using imaginary time.
Interpretation
The inception of the universe can be understood through the concept of imaginary time.
In this quote, Stephen Hawking suggests that the origins of the universe are accessible to scientific understanding through the theoretical framework of imaginary time, which challenges conventional notions of time and space. This perspective provides a unique insight into cosmology, enabling us to theorize about the universe's birth and its fundamental nature beyond traditional temporal constraints.
In practice
During a lecture on modern physics, one could reference this quote to emphasize the importance of innovative thinking in understanding the universe.
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.
The danger is that the compromises and special interests inherent in Kyoto-style targets and cap-and-trade will be accepted because of bureaucratic momentum.
When asked if I am pessimistic or optimistic about the future, my answer is always the same: If you look at the science about what is happening on Earth and aren't pessimistic, you don't understand the data.
But like all power, there are those who want to keep it for themselves. The world's entire scientific and cultural heritage, published over centuries in books and journals, is increasingly being digitized and locked up by a handful of private corporations. Want to read the papers featuring the most famous results of the sciences? You'll need to send enormous amounts to publishers like Reed Elsevier.
Regardless of your sex, if you have elevated testosterone levels in your blood, you're more likely to think a face with a neutral expression is instead looking threatening.
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.
Coal is a portable climate. It carries the heat of the tropics to Labrador and the polar circle; and it is the means of transporting itself whithersoever it is wanted. Watt and Stephenson whispered in the ear of mankind their secret, that a half-ounce of coal will draw two tons a mile, and coal carries coal, by rail and by boat, to make Canada as warm as Calcutta, and with its comfort brings its industrial power.
