We only have to look at ourselves to see how intelligent life might develop into something we wouldn't want to meet.
Stephen HawkingRead
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 greatest gain from space travel consists in the extension of our knowledge. In a hundred years this newly won knowledge will pay huge and unexpected dividends.
You need propellants to accelerate toward Mars, then to decelerate at Mars, again to re-accelerate from Mars to Earth, and finally to decelerate back at Earth. Accordingly, the mass of these required propellants, in short, drives our need for innovative launch vehicles.
The fossil reserves that have already been discovered exceed what can ever be safely used. Yet companies spend half a trillion dollars each year searching for more fuel. They should redirect this money toward developing clean energy solutions
I try to do my science in a moral way, and, I believe that, ideally, science should be looked upon as something that helps us understand our role in the universe.
It is the desire for explanations that are at once systematic and controllable by factual evidence that generates science; and it is the organization and classification of knowledge on the basis of explanatory principles that is the distinctive goal of the sciences.
The ride to orbit was impressive, as it always is. But once I got on board the space station, it really felt like I was visiting an old home; it felt very comfortable.
