If our species is to survive, our future will probably require outposts beyond our own planet.
Interpretation
Human survival may depend on establishing colonies beyond Earth.
Lawrence M. Krauss emphasizes the necessity for humanity to expand its reach beyond Earth to ensure its survival. The quote suggests that as challenges on our home planet grow increasingly daunting, looking to outer space for new habitats and resources might be essential for the continuation of our species.
In practice
In a speech about the future of humanity, one might reference this quote to underline the importance of space exploration.
The one experience that I hope every student has at some point in their lives is to have some belief you profoundly, deeply hold, proved to be wrong because that is the most eye-opening experience you can have, and as a scientist, to me, is the most exciting experience I can ever have.
The ultimate arbiter of truth is experiment, not the comfort one derives from one's a priori beliefs, nor the beauty or elegance one ascribes to one's theoretical models.
I cannot stress often enough that what science is all about is not proving things to be true but proving them to be false.
To the extent that we even understand string theory, it may imply a massive number of possible different universes with different laws of physics in each universe, and there may be no way of distinguishing between them or saying why the laws of physics are the way they are. And if I can predict anything, then I haven't explained anything.
The illusion of purpose and design is perhaps the most pervasive illusion about nature that science has to confront on a daily basis.
The universe is the way it is , whether we like_x000D_ it or not. The existence or nonexistence of a creator is independent_x000D_ of our desires . A world without God or purpose may seem harsh_x000D_ or pointless, but that alone doesn ' t require God to actually exist.
I like to think that Einstein would look at string theory’s journey and smile, enjoying the theory’s remarkable geometrical features while feeling kinship with fellow travelers on the long and winding road toward unification.
Isolated facts and experiments have in themselves no value, however great their number may be. They only become valuable in a theoretical or practical point of view when they make us acquainted with the law of a series of uniformly recurring phenomena, or, it may be, only give a negative result showing an incompleteness in our knowledge of such a law, till then held to be perfect.
Pierre Curie came to see me and showed a simple and sincere sympathy with my student life. Soon he caught the habit of speaking to me of his dream of an existence consecrated entirely to scientific research, and he asked me to share that life.
Taking bold action on climate change simply makes good business sense. It's also the right thing to do for people and the planet. Setting a net-zero GHG emissions target by 2050 will drive innovation, grow jobs, build prosperity, and secure a better world for what will soon be 9 billion people.
My complaint is that there are more books and news articles than there are primary scientific papers. I am probably the biggest critic of the hypesters, because it's dangerous when fields get overhyped.
Dreaming in public is an important part of our job description, as science writers, but there are bad dreams as well as good dreams. We're dreamers, you see, but we're also realists, of a sort.
