Fillmore sighed. "Just the normal ones. Figured out a simple method, just before dozing off to sleep last night, to transfer this planet to an orbit about another sun. Not that it will be of much use. A sun is a sun and it would take thirty seconds solid thought to improve on it, and I don't know anybody capable of that much sustained thought, and there's not much point in transferring this planet, now that we know how to renew the sun whenever it cools too much." "But it's interesting," the bald man pointed out. "It gets sort of dull staying in the same old orbit. I'm in favor of moving to another universe. Why don't you bring the matter before the Council?" "They wouldn't listen. They don't like change. Most of them are aged, and they still think in terms of light and energy. Imagine that in a modern world! Men content to travel at the mere speed of light! Can't get over the idea that breaking through the energy barrier was just like breaking through the sound barrier." "Was it?" "Not exactly. But the theory that at the speed of light matter will change to pure energy was just as ridiculous as the theory that matter would disintegrate into sound waves at the speed of sound. They figure light travels at 186,000 miles per second. Perhaps it does in a straight line. I never thought it was worth the trouble of figuring out. But light waves are always at right angle, different from sound waves, and we must come to the conclusion that light does not travel in a straight line, but in a series of curves. While its theoretical speed is 186,000 miles per second, its actual speed is many times that. Thus we have a constant and a variable. If there were only a constant, it would prove out that matter would become pure energy at the speed of the constant. But it does not, for it must achieve the speed of the variable, and that cannot be achieved without traveling at a million different speeds. And even if matter changed to pure energy it must necessarily change again when it breaks through the energy barrier. But those old slow pokes in the council insist that we go on traveling at less than the speed of light. They do not know that a billion miles per second is considered slow in some laboratories. They may know it but they ignore it. Backward! Stupid! Even the ancients were better informed. They conceived varying dimensions, which is a step in the right direction. Actually we know that there is only one dimension and that is the mental dimension with diverse corridors. But in order to learn that, we had to discover, some fifty thousand years ago, upward of two thousand different dimensions. Then we integrated them and found that they all emanated from the mind. It was merely a matter of mathematics and comprehension. And now everything is accomplished by the mind, and in another hundred thousand years we can dispense with our bodies." "Is that good or bad?"
