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.
For me, arguably the story of telomeres and telomerase began thousands of years ago, in the cornfields of the Maya highlands of Central America.
Mathematics allows for no hypocrisy and no vagueness.
Language is only the instrument of science, and words are but the signs of ideas.
You can't turn on your television without seeing these advertisements about clean coal, clean tar sands and the claim that there's more jobs associated with fossil fuels than other industries. That's of course not true. But they're hammering that into the voters' heads.
One could perhaps describe the situation by saying that God is a mathematician of a very high order, and He used very advanced mathematics in constructing the universe.
Companies are the first to see the costs of climate change.
