The future is an infinite succession of presents.
And if California slides into the ocean, as the mystics and statistics say it will, I predict this hotel will be standing until I've paid my bill.
Happiness is a present attitude and not a future condition.
Imagining in excited reverie That the future years had come, Dancing to a frenzied drum, Out of the murderous innocence of the sea.
The shape of the heaven is of necessity spherical; for that is the shape most appropriate to its substance and also by nature primary.
Our sun enlightens the planets that belong to him; why may not every fixed star also have planets to which they give light?
They have likewise discovered two lesser stars, or satellites, which revolve around Mars, whereof the innermost is distant from the center of the primary exactly three of his diameters, and the outermost five: the former revolves in the space of ten hours, and the latter in twenty-one and a half, so that the squares of their periodical times are very near in the same proportion with the cubes of their distances from the center of Mars; which evidently shows them to be governed by the same Law of Gravitation that influences the other heavenly bodies.
From the moment they had left the Earth, their own weight, and that of the Projectile and the objects therein contained, had been undergoing a progressive diminution. . . . Of course, it is quite clear, that this decrease could not be indicated by an ordinary scales, as the weight to balance the object would have lost precisely as much as the object itself. But a spring balance, for instance, in which the tension of the coil is independent of attraction, would have readily given the exact equivalent of the loss.
Is it not demonstrated that a true flying machine, self-raising, self-sustaining, self-propelling, is physically impossible?
The distance between the earth and her satellite is a mere trifle, and undeserving of serious consideration. I am convinced that before twenty years are over one-half of our earth will have paid a visit to the moon.
Some think that solar work is pretty well played out. In reality, it is only beginning.
A planet is the cradle of mind, but one cannot live in a cradle forever.
No rocket will reach the moon save by a miraculous discovery of an explosive far more energetic than any known. And even if the requisite fuel were produced, it would still have to be shown that the rocket machine would operate at 459 degrees below zero-the temperature of interplanetary space.
The time will come when man will know even what is going on in the other planets and perhaps be able to visit them.
The universe will finally become a ball of radiation, becoming more and more rarified and passing into longer and longer wave-lengths. The longest waves of radiation are Hertzian waves of the kind used in broadcasting. About every 1500 million years this ball of radio waves will double in diameter; and it will go on expanding in geometrical progression for ever. Perhaps then I may describe the end of the physical world as-one stupendous broadcast.
The choice, as Wells once said, is the Universe-or nothing. . . . The challenge of the great spaces between the worlds is a stupendous one; but if we fail to meet it, the story of our race will be drawing to its close. Humanity will have turned its back upon the still untrodden heights and will be descending again the long slope that stretches, across a thousand million years of time, down to the shores of the primeval sea.
The younger generation of rocket engineers is just beginning. They are of the new generation to which space travel is not going to be a dream of the future but an everyday job with everyday worries in which they will be engaged.
Many, and some of the most pressing, of our terrestrial problems can be solved only by going into space. Long before it was a vanishing commodity, the wilderness as the preservation of the world was proclaimed by Thoreau. In the new wilderness of the Solar System may lie the future preservation of mankind.
History will remember the twentieth century for two technological developments: atomic energy and space flight.
We want to build colonies on the Moon, Mars, the Moons of other planets, and even nearby asteroids. We want to make space tourism and commerce routine.
Eventually we must leave Earth-at least a certain number of our progeny must as our sun approaches the end of its solar life cycle. But just as terrestrial explorers have always led the way for settlers, this will also happen extraterrestrially. Earth is our cradle, not our final destiny.
Flight out of the atmosphere is a simple thing to do and should have been available to the public twenty years ago. Ten years from now, we will have space tourism where you will be able to see the black sky and the curvature of the earth. It will be the most exciting roller coaster ride you can buy.
Market studies suggest space tourism-a rubbernecker's trip to earth orbit-is likely to draw 50,000 passengers a year if the ticket can be pushed below $25,000. That's what tens of thousands of people spend each year on competing trips, such as round-the-world cruises on luxury liners and adventure tours to Antarctica or Mount Everest.
Eventually everyone will have the opportunity to travel onto space.
We'll go into orbit. We'll go to the Moon. This business has no limits.
