spaceship light novel

If they were to fly in a light-speed spaceship for an hour, they would have to travel a very long distance at this speed since the speed of light was about 300,000 kilometers per second. However, the reference materials did not mention other specific situations that would happen when flying in a light-speed spaceship for an hour, such as comparing the time with Earth or the specific location. It was only known that if a spaceship that could fly at the speed of light could be built, it would only take about a year to travel through the Milky Way. Therefore, based on the available information, it could only be determined that the spacecraft would fly about 1.08 billion kilometers (300,000 x 60 x 60) in an hour.

Currently, there were no actual light speed ships. Although in sci-fi works such as "Three-body: Death Forever", there were settings for light speed spacecraft (such as the Celestial Ring), humans had yet to build a light speed spacecraft in reality. Although Mexican physicists had proposed the Akubierre engine, a mechanism that could theoretically allow spacecraft to fly faster than light speed, and there were related simulation experiments, the experiments showed that there were many risks in this mechanism. For example, there would be particle accumulation and energy release during superluminal flight. It was difficult to achieve a safe landing, which indicated that there was still a big gap from the creation of a light-speed spacecraft. The novel "Hundred Years of Spaceship" is equally exciting.

The principle of the light sail spacecraft was to use the light pressure produced by the photon to obtain thrust. In the universe, the photons emitted by the stars were like the wind generated by the atmospheric circulation on Earth. They could become the power source for the spacecraft to move forward. When the light sail expanded to a large enough area, the thrust generated by the photon impact on the light sail would cause the spacecraft to move. For example, the light sail of the light sail spacecraft was made of special materials, such as aluminum plated Myra. Its thickness could be as thin as a few hundred atoms in diameter. When the spaceship was illuminated by light, it could use the light sail to carry the light pressure to obtain energy and continue to accelerate. For example, the spacecraft in the " Breakthrough Starshot " program of the United States only weighed about 10 grams. It was integrated with a variety of small but efficient instruments. The external light sail could theoretically accelerate the spacecraft to tens of thousands of kilometers per second in a few minutes under the illumination of light, and finally stabilize at 20% of the speed of light.

According to current scientific knowledge, the speed of light in vacuum (about 299792458 m/s) was the maximum speed of natural objects. It was the upper limit of the speed of all matter movement and information transmission in the universe. It was also the speed of massless particles and the corresponding field fluctuations in vacuum. Theoretically speaking, there were many limitations for objects with mass to reach the speed of light. For example, according to the acceleration transformation in the special theory of relativity, when the spacecraft flew at a constant acceleration, the constant acceleration measured by the spacecraft itself was not constant in the eyes of the Earth observer. Instead, the acceleration gradually decreased as the spacecraft's speed increased. In other words, the closer the spacecraft's speed was to the speed of light, the closer the acceleration measured by the Earth observer was to zero. Therefore, the spacecraft would never reach the speed of light in the eyes of the Earth observer. The current level of human technology was still far from being able to create a spaceship that could reach the speed of light. The novel "Hundred Years of Spaceship" is equally exciting.

The lightspeed spaceship engine was still in the theoretical research and exploration stage. There are many concepts involving the engine of a light speed spacecraft, such as the Alcubierre engine.(It was proposed by the Mexican physicist, Michael Acubierre, in 1994). It could allow a spacecraft to warp space-time in a "warp bubble" formed around it, allowing it to fly faster than the speed of light. There was also a curvature-driven engine, which could compress the space-time around the spacecraft and create a warp bubble to distort space to achieve interplanetary travel. The spacecraft in the warp bubble did not actually move faster than the speed of light, so it did not violate the theory of relativity. In addition, the new engine developed by Elon Musk and NASA claimed to reach 99% of the speed of light. The new engine concept proposed by NASA engineer David Burns could reach 99% of the speed of light without the need for propellants, but this concept still required a lot of theoretical work to achieve.

Different universe ships had different speeds, and the time needed to fly a light year was different. If it was the Voyager 1 probe, its speed relative to Earth reached 17.062 km/s, or 61452 km/h, about 538 million kilometers per year. It would take more than 17500 years to fly a light year at this speed. The New Horizon probe launched in 2006 was even faster than Voyager 1, with a maximum speed of 23.33 km/s, or 84000 km/h. It would take more than 12800 years to travel a light-year at its speed. The average walking speed of a human is about 5 kilometers per hour, and it takes 216 million years to walk one light-year at a walking speed. The fastest human running speed record is 44.72 kilometers per hour. It would take 24 million years to run a light-year at this speed; 18 million years to drive a car at 60 kilometers per hour; 3.6 million years to run a light-year at 300 kilometers per hour by high-speed rail; and 1.2 million years to fly at 900 kilometers per hour by plane.

When a spaceship flew at light speed and emitted light, the situation was more complicated. It needed to be seen from the perspective of the observers inside and outside the spaceship. From the perspective of the observer inside the spaceship, even if the spaceship was moving at the speed of light, when the spaceship turned on the headlights, no matter how fast the spaceship was moving, the light emitted by the spaceship would still travel at the speed of light to the spaceship and the observer inside. From the inside of the spaceship, the light of the headlights would fly forward at a speed of 299792458 meters per second relative to the observer. However, due to the scarcity of objects in space, there was no reflection of light, so it was meaningless to turn on the lights to illuminate the front. From the perspective of an observer outside the spaceship, the spaceship was moving at the speed of light, and the light emitted by the spaceship was also at the speed of light to the observer. The speed of light would not change because of the speed of the light source (the spacecraft). Therefore, from the perspective of an external observer, the speed of the light emitted by the spacecraft was the same. The light could not run faster than the spacecraft. The two were basically on the same level. Due to the Doppler-effect, if the spacecraft moved toward an external observer, the external observer would see the light emitted by the spacecraft blue-shift. The light's wave-length would be compressed to a very short length, even reaching the violet band outside the visible spectrum. When the spacecraft moved away from the external observer, the light red-shift would quickly disappear. At the same time, according to the relativistic effect, when the spacecraft approached the speed of light, there would be time expansion, Lorentz contraction, and mass increase. From the reference frame of the spaceship, light could not exceed the speed of light. The light would form a ray that moved along the direction of the spaceship. It would not illuminate the front of the spaceship, but would form a bright spot along the direction of the spaceship. Observing from outside the spacecraft's frame of reference (such as Earth), due to the relativistic effect, the spacecraft looked like time had slowed down, its length had shrunk, and its mass had increased. The speed of light was constant in any frame of reference. The light emitted by the spacecraft's headlights still traveled at the speed of light, but the frequency of these lights would change (the Doppler-effect). In addition, according to the general theory of relativity, light would bend in the gravitational field. If the spacecraft passed through a strong gravitational field, the light would be bent, possibly forming a halo or other strange shapes. It should be noted that, according to the theory of relativity, the larger the mass of the object, the more difficult it is to approach the speed of light. When the object reaches the speed of light, the energy required is close to infinity, so it is impossible for any object to move at the speed of light. This is only an analysis under theoretical assumptions. The novel "Hundred Years of Spaceship" is equally exciting. Everyone is welcome to click and read it!

At present, the scientific community generally believed that according to current physics theories and understanding of the universe, there were many major challenges in building a lightspeed spacecraft, and there was no feasible manufacturing method. The main challenges were as follows: 1. ** Restrictions of the special theory of relativity **: According to Einstein's special theory of relativity, when an object approaches the speed of light, its mass will increase. When it reaches the speed of light, its mass will approach infinity, which requires infinite energy to accelerate to the speed of light. However, there is currently no solution to overcome the problem of infinite mass increase. 2. [Huge energy requirement: Theoretically speaking, reaching the speed of light requires an infinite amount of energy.] According to the mass-energy equation E = mc2, the greater the mass, the greater the energy required. The current science and technology could not provide such a huge energy density. 3. ** Time Dilation Effect **: The special theory of relativity predicted the time expansion effect. When an object moves at a speed close to the speed of light, time will slow down. This could cause the time experienced by the pilot during the voyage to be out of sync with the time on Earth, which would pose many challenges for long-term space travel. 4. Cosmic radiation hazard: There is a large amount of cosmic radiation in space, especially at speeds close to the speed of light. This radiation can cause serious harm to the spacecraft and its passengers, such as radiation poisoning and cell damage. The novel " Hundred Years of Spaceship " is equally exciting.

According to mankind's current scientific understanding, the speed of light in the universe was the upper limit for the movement of matter and the transmission of information. No object with mass could exceed the speed of light. There was currently no evidence that a spacecraft could reach the speed of light. According to the special theory of relativity, when a spacecraft tried to fly at a constant acceleration, the closer the spacecraft's speed was to the speed of light, the closer the acceleration was to zero, so the spacecraft would never reach the speed of light.
