Chapter 239: Sol Three Hundred and Thirty-Nine, A Truly Unknown Future
Translator: CKtalon Editor: CKtalon
Some time had passed since the sunset.
Tang Yue and Tomcat were sitting on the vehicleâs rooftop, a star chart spread over their knees as they looked up at the sky.
However, todayâs weather was rather gloomy. The sky wasnât starry like usual and the atmosphere was emitting a turbid pale red glow, covering the sky in a seemingly thin veil. Tang Yue narrowed his eyes. âThere are much fewer stars today than yesterday. Thereâs only a few hundred of them.â
âItâs not possible for Mars to always have clear skies, due to inclement weather.â Tomcat widened its eyelids with its paw and swept the sky with its round eyes.
âCan you see them?â
âOf course.â Tomcat turned its head over. âThe average person can identify stars with magnitude five at the very least. Even if your vision is better than most people, your resolving power would at most be around magnitude six. Thatâs a biological limit of you humans. A humanâs pupil doesnât exceed eight millimeters in diameter, and it only allows 20 square millimeters of light in, but Iâm different. Iâm a cat.â
Tomcatâs pupils dilated like a camera lens.
âThe eye structure of mammals are essentially identical to those of cameras and telescopes, but of course, the bigger the aperture, the stronger the resolving power.â
Tomcat seemed rather smug.
âAre you even considered a mammal?â Tang Yue mumbled.
Tomcatâs ears pricked up.
âHow am I not one?â Tomcat corrected him. âWhen it comes to zoological taxonomy, Iâm a vertebrate mammal, a carnivorous feline of the United Nationsâs robotic cat subspecies.â
Tomcat and Tang Yue were determining their longitude using the two Martian moons, Phobos and Deimos. Phobos was rather striking in the clear night sky, with it being a tiny light blob that was about a sixth of the Moonâs size. In fact, its diameter was far smaller than the Moon. Phobosâs diameter was twenty-six kilometers. The reason it looked big was because of its low orbit. It was only six thousand kilometers from the Martian surface and was practically clinging to it in orbit. It circled Mars three times a sol.
As for Deimos, it looked no different from other stars. It was a dim speck of light. If its location wasnât known ahead of time, the average person wouldnât have been able to find it.
Not long ago, Deimos had suffered a collision, sending it off its original trajectory. The energy carried by Comet Tom-Tang-Mai I was astounding. Even a light brush was enough to send the tiny Deimos flying out. Its nearly circular orbit of 23,000 kilometers had now become a huge ellipse.
âPhobos is about to rise again.â Tomcat did a time check and pointed west.
Tang Yue looked in the direction of its paw and under the dark red sky, the blurry blob of light had already risen above the horizon.
Phobos didnât have clear boundaries like the Moon. It was only a huge piece of rock over twenty kilometers in diameter with craters covering its entire surface. In Tomcatâs words, âItâs a potato that a rat has nibbled on.â This tiny piece of rock reflected very little of the sunâs light.
âPhobos is also very dim,â Tang Yue said. âThis darn weather is like thereâs a smog.â
âItâs a result of atmospheric activity. I once told you that the Martian atmosphereâs structure is completely different from Earthâs. Thereâs only a troposphere thatâs dozens of kilometers high.â Tomcat looked up at the sky. âThe wind can sweep the dust and sand high into the sky, then be swept around the globe at altitudes of forty kilometers above us. They could be moved to every corner of this planet.â
âHow is it?â Tang Yue asked. âAre we on the right track?â
âWe have deviated a little.â
âBy how much?â
âFive arcminutes. Itâs within expectations.â Tomcat straightened its arm and shifted slightly to the left. âTomorrow morning, we should head slightly east when we set off.â
âFeel free to do so, youâre the navigator.â Tang Yue lazily leaned back onto the ground. âAs long as we can accurately reach our destination, I donât care if we deviate left or right. Donât you find me very broadminded?â
âHow would I know if you are broadminded or not?â Tomcat shrugged its shoulders. âIf youâre broadminded, do it yourself. I believe you will go off course all the way to the north pole.â
âMagnanimous!â Tang Yue lay beside the cat, turning his head to shout at it.
Tomcat had the star chart covering its face as it leaned back. Propping its head up, it crossed its hindlegs.
Its ears twitched as the star chart rhythmically movedâTomcat was humming a song, but it shook its ears instead of its legs.
âThereâs another thirty kilometers tomorrow. Another thirty kilometers the sol after tomorrow,â Tang Yue said. âWe should arrive on the third sol. These few sols seem to take an eternity.â
âBut only the heavens know whatâs awaiting us on the third sol.â Tomcat turned its head under the chart, revealing its shimmering eyes under the piece of paper. âYou might know whatâs awaiting us tomorrow and the sol after tomorrow, but you have no idea whatâs waiting for us on the third sol. In three sols time, you might be motionless on the ground or have reached the ends of the Universe.â
Tang Yue was taken aback. It took him a few seconds to understand what Tomcat was saying.
He was unable to crack time and see the future. Three sols were actually no different from an infinitely distant future. In three sols, where would he be?
At his destination?
On Kunlun Station?
On Earth?
Or would he be in a particular solar system on a particular galactic arm of the Milky Way, or even a spot beyond the observable Universe?
Apart from the most probable first option, he could be any corner in the Universe.
No.
Was the first option really most probable?
Perhaps the probability of him being in any corner of the Universe was identical.
Tang Yue thought silently.
âWhat do you wish to say?â Tang Yue asked. âWhatâs really unknown is the future?â
âWhatâs really unknown is the future.â
Tang Yue fell silent and took out a pencil from his pocket. He raised it in midair. âActually, we can predict the future. Just like this pencil. If I were to release it, it would immediately drop. By using Newtonâs laws of motion, we can precisely predict its speed and state at any point in time.â
âThen if you release it, will it land on you?â Tomcat asked.
âOf course,â Tang Yue replied.
âThen release it.â
Tang Yue glanced at it, unsure what the point of carrying out the experiment. Any ordinary person could tell that the pencil would fall due to gravity if he released it.
He released his grip.
However, the pencil didnât fall on Tang Yueâs body.
This was because Tomcat had reached out and grabbed it.
âWe can only predict the future in a specific closed system. The unknown influences that come beyond the system are impossible to calculate. Itâs just how using Newtonâs laws of motion will not allow you to predict me suddenly grabbing it.â Tomcat waved the pencil. âPredictions need conditions. Conditions require drawing lines. And since a line is drawn, it means there is an interior and an exterior. This Universeâs exterior is forever an unknown. It can interfere with you and also not interfere with you. The best interference is that an advanced civilizationâs spacecraft suddenly lands in front of us and the next second pulls you up to reach the other end of the Milky Way via a wormhole.â
âThatâs just sophistry.â Tang Yue was at a loss for a comeback.
âBut it adheres to logic.â Tomcat harrumphed.
Tang Yue looked at the dark red sky; his thoughts a mystery. The farthest he could see was the thin clouds twenty kilometers high. And above the clouds, the atmosphere was slowly stirring, carrying billions of tonnes of dust and sand as they began enveloping all of Mars.
