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.
So if the worth of the arts were measured by the matter with which they deal, this art-which some call astronomy, others astrology, and many of the ancients the consummation of mathematics-would be by far the most outstanding. This art which is as it were the head of all the liberal arts and the one most worthy of a free man leans upon nearly all the other branches of mathe matics. Arithmetic, geometry, optics, geodesy, mechanics, and whatever others, all offer themselves in its service.
As a theoretician, I am proud to be part of a counter revolution... discovering that quantum field theory language was not dead and finished but had not really been explored thoroughly enough.
From a genomic perspective, we are all Africans.
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.
Hubble touches people. When you're looking that far out, you're giving people their place in the universe, it touches people. Science is often visual, so it doesn't need translation. It's like poetry, it touches you.
Do not imagine that mathematics is hard and crabbed, and repulsive to common sense. It is merely the etherealization of common sense.
