After a moment of silence, I suddenly remembered to ask, "How do you pilot your flying saucers?"
"The flying saucers are too fast for humans to pilot. They are operated by pre-set computer programs," explained Suldair
"The passage of time inside and outside the saucer is different. Not only do the interior and exterior of the saucer experience time differently, but the area where the pilot controls are located also has a different spacetime from other parts of the saucer.
To fly to a specific planet, we need to measure the distance and coordinates between that planet and ours in advance. We use the travel time of the saucer to control the distance flown. After setting up the pilot program, we can then fly there.
"When the saucer arrives at Earth, we bring it to a quasi-excited state to stop. Then we switch it to an excited state to fly at the speed of light, but the set time is extremely short, allowing the saucer to fly only a tiny distance before switching back to the quasi-excited state.
By continuously changing the spacetime state of the saucer, we can make it fly over Earth at any speed far below the speed of light."
"Does this measurement need to be very accurate? If it's wrong, could the saucer crash?" I asked.
"Definitely. If the measurements are not precise, it's like how accidents happen with your airplanes - crashing into a planet and resulting in destruction and death.
We first use a pre-set computer program to control the saucer to approach your Earth at the speed of light. When near your Earth, we change its spacetime state to continue flying toward your planet at a speed much less than light," said Suldair.
"However, this measurement is not difficult for us. The most advanced technology on Earth is lasers, while we use fields for measurement. You Earthlings use lasers, which are considered the most advanced. We measure with fields, the essence of which is space undergoing cylindrical spiral motion changes. Measuring with fields is much more advanced than with lasers."
Measurement involves the transmission of information. On your Earth, using lasers to measure the position and distance to the Moon requires the reflection of lasers back to determine. This method has obvious flaws, especially for distant planets far from your Earth, where lasers cannot be emitted due to energy dissipation. Additionally, the speed of laser emission and reflection is limited.
However, using our artificial fields for scanning, energy dissipation is zero. Not only can we emit to distant planets, but the field can also move superluminally. The essence of the field is non-physical space, unaffected by the limitation of objects' movement speed not exceeding the speed of light.
Currently, we not only measure the distance and position of distant planets using fields but also observe these distant planets with fields. We also use artificial field scanning for mutual communication, which is far superior to lasers and electromagnetic waves.
For instance, on your Earth, people driving cars can communicate with electromagnetic waves, which generally works fine because the speed of electromagnetic waves is faster than the speed of cars. However, if we were flying around in light-speed saucers in space, using light-speed electromagnetic waves to communicate would be a joke.
Therefore, superluminal artificial field scanning communication is our ideal and only choice.
"Do you also use artificial field scanning for communication on your planet?" I asked.
"Of course, on our planet, we all use artificial field scanning for communication. The advantage of field communication is unmatched by electromagnetic wave communication," Suldair said.
"For example, if a mining disaster occurs in a deep underground coal mine on your Earth, and the mine shaft is buried under thick layers of soil, electromagnetic wave signals from your Earth cannot penetrate the thick layers of soil and cannot contact the outside world.
But if it were us, using the field as a medium for communication, since the essence of the field is space, which can traverse the entire planet, there would be no such obstacle.
For example, when detecting the interior of a planet or predicting earthquakes, artificial field scanning is very convenient.
Field propagation of information not only has powerful penetrative ability with almost nothing to block it, but also has minimal energy dissipation and attenuation during propagation, even reaching zero, and can propagate to very distant places. Only energy is required during signal transmission and reception, with no energy consumption during long-distance transmission.
Another obvious advantage of field propagation of information is that the speed is faster than electromagnetic waves and can theoretically reach almost infinite speed.
The speed of electromagnetic wave propagation is the speed of light. According to the theory of relativity on Earth, the fastest speed in the universe is the speed of light. However, the speed of information transmission through space can be faster than the speed of light. How is this possible?
Space is a special kind of matter, very different from ordinary physical particles, which possess mass and charge. The speed of ordinary objects cannot exceed the speed of light because as the speed of ordinary particles approaches the speed of light, their mass tends towards infinity.
Electromagnetic waves and light are essentially the accelerated motion of charged particles, creating a counter-gravity field. This makes the charged particles, usually electrons, lose their mass and charge characteristics and enter an excited state, moving at the speed of light.
Light itself is also a type of particle, whose wave nature is the wave motion of space itself. Since space is always moving at the speed of light, light is actually stationary in space, moving along with the space at the speed of light. Its speed cannot exceed the speed of light. Any material particle, in its natural state, cannot move faster than the speed of light.
However, space, having no mass or charge and being different from ordinary matter, is not constrained by this limitation.
"Using fields to communicate is a high-level method," Norton says, "because the universe is composed only of material particles and space. Communication using material particles to process information is outdated; using space to transmit information is the most advanced."
"Not only do we use space to transmit information, but on our planet, we also use space to process information on a large scale," Suldair says, "Our computers and the global public information network are like the computers on Earth and the internet that is about to be born. Our computers are virtual, and the public information network relies mainly on space for information transmission.
With our artificial field scanning technology, we can connect the brains of all our people to others and the public information network continuously through space.
Therefore, we don't need computers or other devices to communicate and connect with others or to access the internet.
We also utilize space for storing information in our universe. There's a fundamental theorem in our concept of the space information field about space and information:
Any part of the universe can store all the information from the past, present, and future of the universe. In other words, the capacity of space to store information is theoretically infinite.
However, in practical terms, the ability of space to store information is subject to certain constraints. While not infinite, the capacity for information storage in space would still appear incredibly vast to people on Earth.
Currently, humans are mainly aware of the importance and value of tangible resources like oil, coal, and metals, not yet fully appreciating the significance and value of data and information.
Eventually, people from Earth will uncover the mysteries hidden within space and begin to extensively use it for transmitting, processing, and storing data.
This is particularly true when humans develop spacecraft capable of traveling at light speed. Relying on traditional light-speed electromagnetic waves for communication during interstellar journeys would be ineffective.
Such spacecraft will require a mode of communication that is instantaneous, with a velocity approaching infinity, leveraging the movement of space itself, akin to the concept of quantum entanglement in quantum mechanics.
About an hour later, I noticed the three-dimensional holograms inside the spaceship suddenly vanish. The few red robots, which were slightly trembling, quickly shrank into a small size, turned a purplish-red like liquid droplets, scattered on the ground, and then disappeared into the ship's interior.
The mysterious voice returned in my mind (not through my ears), announcing, "We have arrived at the planet Guoker. It's time to descend."
This soft female voice, which had been continuously speaking, seemed to be guiding or explaining something.
Without realizing it, we had reached their planet. They stood up and announced, "The journey is over. We've reached our planet. Let's head down."
