Chapter 525: Mass Increase Causes Atomic Vibration Frequency to Slow Down
Of course, communication systems also need precise time to maintain. For example, telecommunications companies now transmit voice in the form of data packets instead of the analog circuits used in the past. The advantage of using data circuits to transmit voice is that it allows them to transmit a large amount of voice through telephone lines at the same time.

When you call someone in another city, your voice is broken down and sent between computers at both ends.

One conversation would go back and forth with the other thousands of times per second. However, for all this to happen, the two computers had to be perfectly synchronized, otherwise the conversation would be garbled and sound like gibberish. This is why telecom companies now have atomic clocks - so that the computers are perfectly synchronized at all times.

Of course, accurate time is not only needed in scientific research and communication, but also in war. In anti-Japanese war movies and TV dramas, on the eve of the war, the commanders would always gather together with serious expressions, stretch out their wrists to check their watches, so as to act in unison.

For example, in Bright Sword, Yamamoto Ikki checked with his adjutant before launching the attack on Zhao Jiayu.

There was no way around it. The mechanical watches of that era had large errors. An error of more than ten seconds a day was normal, and an error of several minutes over a long period of time was not surprising. So if you didn't check the watch and didn't grasp the timing of the attack, it would be embarrassing.

For example, if we agree on an attack at 8 o'clock, but the time on the watch is wrong, the front attacker launches the attack before the attackers from behind climb up the cliff. In this way, the effect of encirclement from front and back cannot be achieved!

Of course, in modern warfare, the synchronization of various combat systems depends on atomic clocks.

With the development of modern warfare, accurate time systems have become the key to cyber warfare, and the time-frequency system is the foundation of a country's national defense. As the most accurate time acquisition and measurement tool in the world, atomic clocks are a strategic resource for a country. Cutting-edge weapons, aerospace systems, and the launch and tracking of missiles and rockets are all inseparable from them.

For example, if you want to improve the hit rate of guided weapons, you must improve the accuracy of timing. Otherwise, there will be the consequence of "a slight error leads to a great error". It can be said that without high-precision time measurement, most of the current precision-guided weapons will be useless.

In terms of joint operations, all combat equipment in future unmanned combat systems or integrated air-space combat networks will require high-precision time synchronization. Satellites, aircraft, missiles, ground radars, ships and other equipment all require a high-precision local clock - an atomic clock, and achieve time synchronization through electromagnetic waves or optical fibers. Only in this way can the accuracy of detection, early warning and strike be improved, while improving the efficiency of joint operations.

Of course, as time goes by, we have already arrived in the 23rd century in the blink of an eye!

We have experienced deep space exploration, space wars, and even stellar explosions, and we naturally know that these are inseparable from long-distance positioning and navigation. However, while technology in all areas is developing, the timekeeping is still stuck in the 20th century, and the atomic clocks invented in the 20th century are still used.

For nearly three hundred years, the humans wandering on the Blue Planet have not made any progress in timekeeping and still rely on atomic clocks.

However, with the realization of superluminal travel, humans wandering on the blue planet began to realize that the time dilation effect of relativity should be wrong.

After all, they have already carried out space jumps and curvature navigation. Although these things did not exceed the speed of light directly, they did exceed the speed of light laterally.

However, Einstein's prediction that superluminal travel might be able to return to the past did not come true.

It was even discovered that after a space jump, the speed of the atomic clock did not slow down like direct sub-light speed travel.

So this point alone is enough to refute the time dilation effect of the theory of relativity. So if this is the case, then what exactly causes the atomic clock to slow down?

The atomic clock's timing relies on the relatively stable high-frequency oscillation frequency of the atomic nucleus, which makes the atomic clock's timing so accurate.

So what exactly can affect the oscillation frequency of the nucleus itself?

This is obviously the speed, so the scientists on the Wandering Blue Planet quickly thought of whether the speed close to the speed of light produced a mass increase effect, which then caused the oscillation of the atomic nucleus to slow down.

After many experiments, it was discovered that the mass increase effect would indeed change the oscillation frequency of the atomic nucleus, slowing down the oscillation frequency of the atomic nucleus, thus affecting the counting of the atomic clock. Of course, even if we know this, we cannot feel that there is no connection between speed and time at this stage, so it is of no particular use.

At most, you don't have to worry about traveling around outside on a spaceship and then returning home to find that you are still young but your wife has become old and ugly.

Of course, although there was not much use in figuring out this problem, Liu Xiu still gave the scientific research team that figured it out the problem the title of the Wandering Blue Planet's Highest Scientific Progress General.

However, the most critical issue at the moment is how to develop a clock that can reduce the housing quality increase effect.

As for this problem, the scientists of Wandering Blue Star have actually considered the possibility that the speed of photons will slow down after refraction or when they enter other barrier.

Therefore, photons were not chosen as timing devices.

In fact, another proof that time is not affected by speed is quantum entanglement communication technology.

Because when conducting quantum communication on a sub-light speed spacecraft, one does not feel that time is slowing down.

You can still communicate on the phone, and the speaking speed of both parties is still the same as normal.

It is precisely because of such proof that it is completely proved that speed does not dilate the so-called time, and Einstein's theory of relativity is not completely correct.

Of course, although it has been disproven that speed does not dilate time, it has indirectly proved again that speed does increase the mass of matter.

And the closer you get to the speed of light, the greater the increase in mass will be.

However, with the in-depth study of space stones, a phenomenon was discovered, that is, the closer to the speed of light, the mass of an object becomes infinite, while the kinetic energy function in the early stage is still very linear.

Because the space composed of space particles will produce violent conflicts with space particles when its speed is approaching the speed of light, resulting in a sharp increase in the mass of matter, but the speed never increases.

Because the faster the speed, the more rare space particles there are, and the more space particles there are, the heavier the object will naturally become.

Finally, heavier objects will naturally find it more difficult to break the speed of light.

This is a bit like the previous aircraft on the blue planet. When breaking the sound barrier, the energy required is extremely large.

Of course, it’s not as exaggerated as breaking the speed of light.

The biggest obstacle to breaking the speed of sound is naturally the air, but the air pressure and air density are different, so the speed of breaking the speed of sound is actually different. For example, the greater the air density, the higher the speed of sound, and the lower the air density, the lower the speed of sound.
