"It is necessary for me to go back a little," he said, "in order that you may understand the situation which confronts us. As you know, our sun and its eight spinning planets are not motionless in space. Our sun, with its family of worlds, has for eons been moving through space at the approximate rate of twelve miles a second, across the Milky Way. You know, too, that all other suns, all other stars, are moving through space likewise, some at a lesser speed than ours and some at a speed inconceivably greater. Flaming new suns, dying red suns, cold dark suns, each is flashing through the infinities of space on its own course, each toward its appointed doom.
"And among that infinity of thronging stars is that one which we know as Alto, that great red star, that dying sun, which has been steadily drawing near to us as the centuries have passed, and which is now nearest to us of all the stars. It is but little larger than our own sun, and as you all know, it and our own sun are moving toward each other, rushing nearer each other by thousands of miles each second, since Alto is moving at an unthinkable speed. Our scientists have calculated that the two suns would pass each other over a year from now, and thereafter would be speeding away from each other. There has been no thought of danger to us from the passing of this dying sun, for it has been known that its path through space would cause it to pass us at a distance of billions of miles. And had the star Alto but continued in that path all would have been well. But now a thing unprecedented has happened.
"Some eight weeks ago the South Observatory on Mars reported that the approaching star Alto seemed to have changed its course a little, bearing inward toward the solar system. The shift was a small one, but any change of course on the part of a star is quite unprecedented, so for the last eight weeks the approaching star has been closely watched. And during those weeks the effect of its shift in course has become more and more apparent. More and more the star has veered from the path it formerly followed, until it is now many millions of miles out of its course, with its deflection growing greater every minute. And this morning came the climax. For this morning I received a telestereo message from the director of the Bureau of Astronomical Science, on Venus, in which he informed me that the star's change of course is disastrous, for us. For instead of passing us by billions of miles, as it would have done, the star is now heading straight toward our own sun. And our sun is racing to meet it!
"I need not explain to you what the result of this situation will be. It is calculated by our astronomers that in less than a year our sun and this dying star will meet head on, will crash together in one gigantic flaming collision. And the result of that collision will be the annihilation of our universe. For the planets of our system will perish like flowers in a furnace, in that titanic holocaust of crashing suns!"

Mur Dak's voice ceased, and over the great hall there reigned a deathlike silence. I think that in that moment all of us were striving to comprehend with our dazed minds the thing that Mur Dak had told us, to realize the existence of the deadly peril that was rushing to wipe out our universe. Then, before that silence could give way to the inevitable roar of surprise and fear, a single member rose from the Mercury section of the Council, a splendid figure who spoke directly to Mur Dak.
"For a hundred thousand years," he said, "we races of man have met danger after danger, and have conquered them, one after another. We have spread from world to world, have conquered and grasped and held until we are masters of a universe. And now that that universe faces destruction, are we to sit idly by? Is there nothing whatever to be done by us, no chance, however slight, to avert this doom?"
A storm of cheers burst out when he finished, a wild tempest of applause that raged over the hall with cyclonic fury for minutes. I was on my feet with the rest, by that time, shouting like a madman. It was the inevitable reaction from that moment of heart-deadening panic, the uprush of the old will to conquer that has steeled the hearts of men in a thousand deadly perils. When it had died down a little, Mur Dak spoke again.
"It is not my purpose to allow death to rush upon us without an effort to turn it aside," he told us, "and fortune has placed in our hands, at this moment, the chance to strike out in our own defense. For the last three years Sarto Sen, one of our most brilliant young scientists, has been working on a great problem, the problem of using etheric vibrations as a propulsion force to speed matter through space. A chip floating in water can be propelled across the surface of the water by waves in it; then why should not matter likewise be propelled through space, through the ether, by means of waves or vibrations in that ether? Experimenting on this problem, Sarto Sen has been able to make small models which can be flashed through space, through the ether, by means of artificially created vibrations in that ether, vibrations which can be produced with as high a frequency as the light-vibrations, and which thus propel the models through space at a speed equal to the speed of light itself.
"Using this principle. Sarto Sen has constructed a small ten-man cruiser, which can attain the velocity of light and which he has intended to use in a voyage of exploration to the nearer stars. Until now, as you know, we have been unable to venture outside the solar system, since even the swiftest of our gravity-screen spaceships can not make much more than a few hundred thousand miles an hour, and at that rate it would take centuries to reach the nearest star. But in this new vibration-propelled cruiser, a voyage to the stars would be a matter of weeks, instead of centuries.
