In the far, far future, essentially all matter will have returned to energy. But because of the enormous expansion of space, this energy will be spread so thinly that it will hardly ever convert back to even the lightest particles of matter. Instead, a faint mist of light will fall for eternity through an ever colder and quieter cosmos.

Ours is essentially a tragic age, so we refuse to take it tragically. The cataclysm has happened, we are among the ruins, we start to build up new little habitats, to have new little hopes. It is rather hard work: there is now no smooth road into the future: but we go round, or scramble over the obstacles. We've got to live, no matter how many skies have fallen.
D. H. Lawrence
I am certain I have not a right feeling towards women - at this moment I am striving to be just to them, but I cannot. Is it because they fall so far beneath my boyish imagination? When I was a schoolboy I thought a fair woman a pure Goddess; my mind was a soft nest in which some one of them slept, though she knew it not.
John Keats
Hereditary succession has no claim. For all men being originally equals, no one by birth could have the right to set up his own family in perpetual preference to all others for ever, and tho' himself might deserve some decent degree of honours of his contemporaries, yet his descendants might be far too unworthy to inherit them.
Thomas Paine
The mere formulation of a problem is far more often essential than its solution, which may be merely a matter of mathematical or experimental skill. To raise new questions, new possibilities, to regard old problems from a new angle requires creative imagination and makres real advances in science.
Albert Einstein
Space has not changed but technology has, in many cases, improved dramatically. A good example is digital technology where today's cell phones are far more powerful than the computers on the Apollo Command Module and Lunar Module that we used to navigate to the moon and operate all the spacecraft control systems.
