Eleven.
Atom lifted the heavy crucible loaded with the molten iron with the aid of the hoist. He dragged the heavy glowing container of the 3000 degree liquid metal towards the waiting sand molds and carefully tipped the spout pouring the yellow hot metal into the openings in the flasks. He'd quickly learned the job of a sand crab. Ramming up a wooden flask full of the moist gritty green sand, forming a mold in the stuff from a wooden or plaster form, setting up the sprue channels for the liquid metal, and spooning off the dross from the top of the crucible before pouring the metal into the molds.
With the four flasks now full, Atom dumped the excess metal into an ingot mold so as not to let the remaining material harden in the bottom of the crucible and possibly crack it. The pots he used to melt metal in were themselves made in the same furnace that melted the raw metal. Atom had made them on a potter's wheel, or formed them using wooden molds from clay mixed with grog and foundry sand. The smallest held just a few pounds of molten metal, the largest nearly a quarter ton.
It would take several hours for the newly poured metal to cool, but by dinner time he would be able to crack open the molds and extract the replacement bearings for the observatory dome. Cobalt would be pleased.
Old man Tom Tesla was more than pleased with Cobalt and Titans work. In the span of less than two months since they had arrived, they had fine tuned the operation of the power station. Old arching contacts had been replaced, over loaded circuits had been bridged with heavier wiring, and the tired relays that kept tripping for no reason were repaired or replaced. The village folk ceased complaining about frequent black outs, and for the first time in anyones memory it was possible to extend the service area of the power grid to parts of the countryside that had to be lit by tallow candles and animal fat lamps.
During his exploration of the countryside, Cobalt had located a rich vein of Wolframite, and he was now working on a process for separating the tungsten metal from the iron and manganese it also contained. He hoped to soon produce light bulbs with double the efficiency and output of the ancient carbon filament lamps now in use.
Now that the power plant was in much better shape and didn't require his constant attention, Cobalt was able to devote some of his time to getting the science laboratory facility into usable condition. The first item he put his mind to was the observatory. The old refracting telescope was actually in decent shape, but its bearings and clock drive would have to be taken apart and repaired. The optical tube appeared to be in decent alignment, but the objective lens had become covered with a film of mold and would need to be removed from the instrument and re-polished. This would have to be done carefully so as to preserve the optical surfaces, but Cobalt intended to optically test the objective anyway.
The big problem was that the dome roof was frozen stuck and couldn't be opened. He and Atom had studied the problem and determined that they'd have to jack up the dome and replace several of the frozen bearings. Cobalt took careful measurements of the old parts and modeled them in clay, adjusting the actual size to account for shrinkage of the clay when it was fired, and that of the metal that the new parts would be cast in. He'd given the ceramic models to his brother who promised to cast replacements in the foundry. Tonight, with any luck they would finally get the old dome operating again.
The two brothers met in the tavern for dinner. Cobalt insisted that he was buying, and he ordered a huge rack of lamb for the two of them. As they ate their dinner Atom stared across the room at a pair of men that somehow looked familiar to him. Both wore eye glasses, one sported a pair of dark sunglasses, the other one had clear lenses that were obviously intended to correct a myopic condition. Atom shrugged his shoulders and gave up trying to remember where he had last seen those two. Like most of the new comers he had only partial recall of his previous existence. He could remember most of the events in his past lives, but some of the fine details were missing.
Why are you so interested in getting that old telescope working again? Atom asked his brother between bites of lamb.
Well besides the fact that it is a classic refracting telescope very similar to those once made by Fraunhofer and Alvin Clark, Cobalt replied, the telescope and the spectroscopic equipment will enable me to figure out just where we really are, both in space and time.
What's so important about that? Atom asked.
I hope to figure out just how far in the future we are from where we were. Cobalt said. I'd like to know how far from old Earth we are as well.
Does it matter? Atom asked. In all probability Earth doesn't even exist anymore anyway.
True. Cobalt sighed. But I'd like to think that our being here means something. Why were we reborn, and why in flesh and blood form? Who did this?
You're asking questions that old religions never could answer. Atom told him. Do you want to find God?
No. Cobalt answered. I think that would disappoint me. But I would also like to know if we are alone. Isn't that what mankind always wanted to know?
That is a deep philosophical question. Atom said. I didn't know you were interested in that sort of stuff.
Actually it's mostly just my scientific curiosity, but also a chance to finally answer a question that cosmologists have been trying to answer for so many years. Cobalt said.
What question is that? Atom wondered.
How it all will end. It's been known how the universe came into being since the middle of the 20th century, though concrete proof didn't come along for some years after. Cobalt began. The Big Bang theory was an established fact by the beginning of the 21st century, but there remained several theories on how the universe would end. Many thought that the expansion of the universe first discovered by Hubble would eventually slow and even reverse, with the universe falling back on itself in a big crunch. It was eventually discovered that there wasn't enough mass in the universe to halt the expansion, in fact the expansion was accelerating. Since accepted theories of gravity didn't allow for that various fudge factors were added to equations leading to the theoretical existence of both dark matter and dark energy.
Sounds weird to me. Atom said, with a mouthful of potatoes.
Perhaps that's because you were never interested in Astronomy and Cosmology, Cobalt replied. Anyway adding those fudge factors resulted in several consequences. Depending on the values that a few resulting constants would take the universe might now have several different fates in store for it. Given one set of values the expansion would continue forever with the universe gradually cooling off and becoming quite dark as entropy takes over. Change those constants slightly and the expansion will eventually slow down with somewhat the same effect, but the universe ends up being smaller and less dark because the galaxies don't become so separated that light can't travel between them. Finally there is one other possibility, that the expansion continues to accelerate as dark energy dominates and everything rips apart. All matter down to the subatomic level disintegrates and there is nothing left but a very thin soup of the most basic particles of energy which finally disappear.
Now that sounds depressing. Atom said. Any ideas which of those scenarios will play out, and when?
I won't know until I can get the telescope working and gather some observational data. Cobalt said. Give what I can see with my naked eyes, I do think we are fairly far along the expansion with only red dwarf stars left, at lest in this part of the universe.
Later that evening in the ancient observatory, the two of them labored at repairing the operation of the dome. Cobalt carefully examined the replacement parts that his brother had cast in the foundry and pronounced them perfect. They climbed up to the top of the dome on separate ladders and inserted a pair of jacks between the top of the wall and the dome. Atom had cast the screw jacks from the best grade of metal that he could find, and had lubricated them using vegetable oil mixed with animal fat. Petroleum based lubricants were unknown in this world, so more natural products were substituted.
It took them several hours to lift the dome one section at a time, remove the rusted parts and replace them with the newly cast ones. By the time they were ready to quit for the night they had installed all of the replacements that Atom had brought with him. Cobalt would still have to get the gearing system repaired before he would be able to operate the dome, but they had just finished the hardest part.
As the two brothers packed it in for the night and put their tools away Cobalt suddenly face palmed with a look of embarrassment. Crap! he said, I almost forgot to tell you that we've been invited for dinner tomorrow evening. Uran and Titan are having their house warming, they finally have the place respectable enough to invite company over.
You know, they're a bit crazy. Atom laughed. Like we would even notice a sloppy household. Both of them have seen the mess I live in next door to the shop. And while your place is a magnitude of order cleaner than mine, it takes first prize for clutter. How could they keep a worse household than either of us?
That's the difference between men an women I guess. Cobalt laughed. Every time I walked over there with Titan to follow him home he made me stand outside the door. Uran wouldn't let me see the inside of the place because she would be too embarrassed to let me see the mess.
Well I'm glad they got the place fixed up to their satisfaction. Atom replied. It's been almost two weeks since they had their marriage ceremony, and they've been spending their honeymoon doing house work?
Now that they've gotten that out of the way I hope that they actually DO have a proper honeymoon, Cobalt said. I don't think they've even consummated their marriage yet. I've tried to convince them that they have nothing to worry about, I'm certain that genetically they are no closer related than second cousins just as the doctor surmised.
Now THAT'S funny! Atom chuckled.
I'll stop by the blacksmith shop about two hours before to remind you, Cobalt said, Otherwise, knowing you, you'll forget, or show up in those filthy clothes you wear in the shop and never wash.
You're probably right about that. Atom laughed. I'll be expecting you then, unless I forget.
