even in the daytime the Sun is little better than a star.”
His tongue, loosened by visitors to talk to, rambled on. 'A fellow gets kind of queer out here,' he told them.
'It's enough to make anyone get queer. I think the doctor is half crazy from staying here too long. He thinks he's getting messages from some place far away. Acts mysterious about it.”
'You think he just imagines it?' asked Herb.
'I'm not saying one way or the other,' declared Smith, 'but I ask you…
where would you get the messages from? Think of the power it would take just to send a message from Alpha Centauri. And that isn't so very far away. Not so far as stars go. Right next door, you might say.”
'Evans is going to fly there and back,' Herb reminded him.
'Evans is space-nuts,' said Smith. 'With all the solar system to fool around in, he has to go gallivanting off to the stars. He hasn't got a chance. I told him so, but he laughed at me. I'm sorry for him. He's a nice young fellow.”
They mounted the steps, hewn out of living stone, which led to the main airlock of the laboratory building. Smith pressed a button and they waited.
'I suppose you'll want Andy to go over your ship,”
Smith suggested.
'Sure,' said Gary. 'Tell him to take good care of it.”
'Andy is the fueling-station man,' the radio operator explained. 'But he hasn't much to do now. Most of the ships use geosectors. There's only a few old tubs, one or two a year, that need any fuel. Used to be a good business, but not any more.”
The space lock swung open and the three stepped inside. Smith remained by the doorway.
'I have to go back to the shack,' he said. 'I'll see you again before you leave.”
The lock hissed shut behind them and the inner screw began to turn. It swung open and they stepped into a small room that was lined with spacesuits hanging on the wall.
A man was standing in the center of the room. A big man, with broad shoulders and hands like hams. His unruly shock of hair was jet-black and his voice boomed jovially at them.
'Glad to see all of you,' he said and laughed, a deep, thunderous laugh that seemed to shake the room.
Gary swung back the helmet of his suit and thrust out a gloved hand.
'You are Dr. Kingsley?' he asked.
'That's who I am,' boomed the mighty voice. 'And who are these folks with you?”
Gary introduced them.
'I didn't know there was a lady in the party,' said the doctor.
'There wasn't,' said Herb. 'Not until just recently.”
'Mean to tell me they've taken to hitch-hiking out in space?”
Gary laughed. 'Even better than that, doctor,' he said. 'There's a little story about Miss Martin you'll enjoy.”
'Come on,' he roared at them. 'Get out of your duds. I got some coffee brewing. And you'll want to meet Tommy Evans. He's that young fool who thinks he's going to fly four light-years out to old A.C.”
And at just that moment Tommy Evans burst into the room.
'Doc,' he shouted, 'that damn machine of yours is at it again.”
Dr. Kingsley turned and lumbered out, shouting back at them.
'Come along. Never mind the suits.”
They ran behind him as he lumbered along. Through what obviously were the laboratory's living quarters, through a tiny kitchen that smelled of boiling coffee, into a workroom bare of everything except a machine that stood in one corner. A red light atop the machine was blinking rapidly.
'Whatever you say is off the record, is off the record,' Gary told him.
'There's so much of it,' rumbled the doctor, 'that sounds like sheer dream stuff.”
'Hell,' said Evans, 'there always is in everything new. My ships sound like it, too. But the thing will work. I know it will.”
Kingsley perched himself on a heavy kitchen chair.
'It started more than a year ago,' he said. 'We were studying the cosmics.
Elusive things, those rays. Men have studied them for about five thousand years and they still don't know as much about them as you think they would after all that time. We thought at first that we'd made a really astounding discovery, for our instruments, used on top of the building, showed that the rays came in definite patterns. Not only that, but they came in definite patterns at particular times. We developed new equipment and learned more about the pattern. We learned that it occurred only when Pluto had rotated into such a position that this particular portion of the planet was facing the Great Nebula in Andromeda. We learned that the pattern, besides having a certain fixed physical structure, also had a definite time structure, and that the intensity of the bombardment always remained the same. In other words, the pattern never varied as to readings; it occurred at fixed intervals whenever we directly faced the Great Nebula, and the intensity varied very slightly, showing an apparent constant source of energy operating at specific times. In between those times our equipment registered the general haphazard behavior one would expect in cosmic rays.”
The doctor rumbled on: 'The readings had me down. Cosmic simply shouldn't behave that way. There never had been any instance of their behaving that way at any time before. Of course, this was the first thorough investigation far from the Sun's interfering magnetic fields. But why should they behave in that manner only when we were broadside to the Great Nebula?
'My two assistants and I worked and studied and theorized and it finally came down to just one thing. The things we were catching with our instruments weren't cosmic rays at all. They were something else. Something new. Some strange impulse coming to us from outer space. Almost like a signal. Like something or someone or God-knows-what was signaling to someone or something stationed here on Pluto. We romanticized a bit. We toyed with the idea of signals coming from another galaxy, for you know the Great Nebula is an exterior galaxy, a mighty star system, some nine hundred million light years across intergalactic space.
'But that was just imagining. There was nothing to support it in the light of factual evidence. We still aren't sure what it's all about, although we know a great deal more now than we did then.
'The facts we did gather, you see, indicated that whatever we were receiving must be definite signals, must originate within some sort of intelligence. Some intelligence, you see, that would know just when and where to send them. But there was the problem of distance. Just suppose for a moment that they were coming from the Great Nebula. It takes light almost a billion years to reach us from the Nebula. While it is very probable that the speed of light can be far exceeded, there is little reason to believe at present than anything could be so much faster than light that signaling could be practical across such enormous space. Unless, of course, the matter of time were mixed up a little, and when you get into that you have a problem that takes more than just a master mind. There was just one thing that would seem a probable answer… that if the signals were being sent from many light years distant, they were being routed through something other than all that space. Perhaps through another continuum of space-time, through what you might call, for the want of a better term, the fourth dimension.”
'Doctor,' said Herb, 'you got me all balled up.”
Dr. Kingsley's chuckle rumbled through the room.
'It had us that way, too,' he said. 'And then we figured maybe we were getting pure thought. Thought telepathed across the light years of unimaginable space. Just what the speed of thought would be no one could even guess. It might be instantaneous… it might be no faster than the speed of light… or any speed in between the two. But we do know one thing: that the signals we are receiving are the projection of thought.
Whether they come straight through space or whether they travel through some shortcut, through some manipulation of space-time frames, do not know and I probably will never know.
'It took us months to build that machine you saw in the other room.
Briefly, it picks up the signals, translates them from the pure energy of thought into actual thought, into symbols our mind can read. We also developed a method of sending our own thoughts back, of communicating with whatever or whoever it is that is trying to talk with Pluto. So far we haven't been successful in getting an entire message across. However, apparently we have succeeded in advising whoever is sending out the messages that we are trying to answer, for recently the messages have changed, have a note of desperation, frantic command, almost
