Venus and Earth and all the planets act like giant vacuum cleaners of space, pulling into themselves all the space debris and meteors within millions of miles by their gravitational attraction." Swiftly the planet expanded below them growing vaster with each passing moment.
There can be no space nor any part of space without gravitational potentials; for these confer upon space its metrical qualities, without which it cannot be imagined at all. The existence of the gravitational field is inseparably bound up with the existence of space.
But we were never able to perfect a telescope that could bring a single sun into view. "Nor did we ever have a chance to do this. The dust-cloud surged out toward us every twenty years, and our scientists were able to use a gravitational beam to deflect a part of it toward our sun. In this way we kept it alive and might have been able to do so for ages. But now the dust-cloud is gone."
They had been compelled to guard against sudden motion; a step, instead of carrying them one stride, might hurl them the length of the room. This lowered gravitational pull helped to explain to the pilot that outer world.
There was merely that recording telling him that the numbers were disconnected. And so he felt disconcerted as if he were now walking through the gravitational force of a different planet. He went back to the table and drank the rest of his orange juice. It was to be expected, he told himself, as nothing was permanent. He took a deep breath and then breathed out fully.
Yet nature makes use of number as a regulating factor in quite a different way from its appearance in the purely electrical and gravitational connexions of inorganic matter, namely where sound-ether from the upper boundary of nature so regulates nature's dynamic that the manifold sense-qualities appear in their time-and-space order.
I began to comfort her and myself by repeating all that Ogilvy had told me of the impossibility of the Martians establishing themselves on the earth. In particular I laid stress on the gravitational difficulty. On the surface of the earth the force of gravity is three times what it is on the surface of Mars.
We may also address ourselves to a more noble form of energy, and ask ourselves whether we are not, for the first time, in presence of a transformation of gravitational energy. It may be singular, but it is not absurd, to suppose that the unit of mass of radium is not attached to the earth with the same intensity as an inert body.
"That's not bad when you think that Mercury is the fastest planet, and it only makes about thirty miles a second." "Right," Rip agreed. "After the asteroid is kicked out of orbit, it will fall toward the sun. At our closest approach to the sun, we'll have enough velocity to carry us past safely. Then we'll lose speed constantly until we come into Earth's gravitational field and have to brake."
That means we'd have to lift about five million tons of mass. As we get farther out, our weight will decrease as the gravitational attraction drops off, but we would need such vast amounts of energy that they are beyond human conception. "We have burned up two tons of matter recharging the coils, and are now using another two tons to recharge them again.
