10,000 Years From Now (1922)
The February 12, 1922 Ogden Standard-Examiner (Ogden, UT) published this page, speculating on the world 10,000 years hence. The piece is a shortened article by Hugo Gernsback with illustrations by Louis Biedermann. Excerpts appear below.
The up-to-date scientist has little difficulty in predicting certain things that will happen in ten or fifty years, but a hundred centuries hence is a larger order, even for the most intrepid imagination. That practically nothing of our present civilization will be left after 10,000 years may be safely predicted. We may also prophesy that human beings, a hundred centuries hence, will live in entirely altered circumstances from those in which we now exist.
Our illustration depicts one of the future cities floating high in the air, several miles above the earth. The question of sustaining such a large body in a rareified atmosphere will prove to be of little difficulty to our future electrical engineers. Just as we construct leviathans of the sea to-day, some of them weighing as much as 50,000 tons we shall construct entire cities weighing billions of tons, which will be held in space not by gas balloons, propellers, or the like antiquated machinery, but by means of gravity-annulling devices. Already experiments have been made whereby it has become possible to reduce the weight of substances by electrical forces.
