A light speed spaceship was a spaceship that could theoretically fly at the speed of light. According to Einstein's theory of relativity, objects with static mass could not reach the speed of light, because as the speed of the object approached the speed of light, its momentum tended to be infinite, which contradicted the limited mass energy of the universe. However, the concept of a light speed spacecraft existed in science fiction works, such as the Celestial Ring in " Three Bodies 3: Death's Eternal Life." The fifth generation was the first light speed spacecraft created by humans. In theory, the Mexican physicist, Michael Akubierre, proposed the Akubierre engine in 1994. This theoretical mechanism could allow a spacecraft to warp space-time in a " warp bubble " formed around it, allowing it to fly faster than light speed. However, relevant simulations showed that there were risks in this way. For example, during superluminal flight, particles that were opposite to the energy contained in the Akubierre bubble would accumulate in front of the bubble. This could cause the spacecraft to be unable to land safely. According to the concept of the light speed spaceship, if the spaceship really reached the speed of light, according to the speed time expansion theory, time would stop in the spaceship, the distance would be zero, the cell metabolism would also stop, and the human body would not age. However, this was only a hypothesis based on theory. In reality, humans faced many theoretical and practical limitations when creating light speed spaceships.

A light speed spaceship was a spaceship concept that could reach the speed of light (about 30km/s). In the sci-fi work "Three-body 3: Reaper's Eternal Life," there were five generations of Celestial Ring. The fifth generation was the first light-speed spacecraft created by humans. It was developed by the Celestial World Corporation and was dedicated to Cheng Xin. It was shaped like a water droplet and could rotate in an axis to create gravity. The four spherical ecological zones at the thickest part could face the bottom in various directions to adapt to various acceleration environments. At the last moment of the two-dimensional transformation of the solar system, Luo Ji revealed to Cheng Xin the curvature engine on Celestial Ring. Once the engine was used, it could reach the speed of light in about an hour, allowing Cheng Xin and Aiaa to carry it to escape the falling solar system. Due to the speed of light, the original 286-light-year journey of Celestial Ring took only 52 hours to reach the system. In reality, the speed of light was the fastest known flight speed of humans. There was no conclusion as to whether humans could build a light speed spaceship in their lifetime. The novel "Hundred Years of Spaceship" is equally exciting.

At present, the speed of light for spaceships was more of a theoretical and sci-fi topic. In theory, the Mexican physicist, Michael Acubierre, proposed the Acubierre engine in 1994. This theoretical mechanism could allow the spacecraft to distort space-time in the surrounding " warp bubble " to achieve superluminal flight. The curvature-driven engine compressed the space-time around the spacecraft, creating a warp bubble to distort space for interplanetary travel. The spacecraft did not actually move faster than light speed in the warp bubble, which did not violate the theory of relativity. In sci-fi works such as Liu Cixin's " Three-Body ", the third part," Death's Eternal Life," humans developed the light speed spacecraft " Celestial Ring ", which involved a curvature-driven engine. However, in reality, although NASA researchers were researching superluminal engine technology, they had yet to achieve the speed of light. And even if it was a light speed ship, the diameter of the Milky Way was 100,000 light years. It would take hundreds of millions of years to leave the Milky Way. From the perspective of the theory of relativity, if a person was in a light speed spaceship, theoretically, time would stop, the distance would be zero, and the cells would not undergo metabolism, so the person would not age. Furthermore, according to the Lorentz transformation, even if there were other movements on the light speed spaceship, it would not exceed the speed of light.

According to the theory of relativity, if a light beam was emitted from a light speed spaceship, the speed of this light beam would still be the speed of light and would not overlap with the speed of the spaceship. From the inside of the spaceship, light traveled at the speed of light. From the outside of the spaceship, due to the relativistic effect, the frequency of light would change, and the spaceship would appear to slow down, shrink in length, and increase in mass. At the same time, if the spaceship passed through a strong gravitational field, the light would bend. However, the theory of relativity stipulated that any object's mass would approach infinity when it was close to the speed of light, and the energy required would also approach infinity. Therefore, the spacecraft flying at the speed of light was only a hypothesis. The novel " Hundred Years of Spaceship " is equally exciting. Everyone is welcome to click and read it!
According to the concept of time relativity in the theory of relativity, when the spacecraft approached the speed of light, there would be a time expansion effect, which meant that time in the spacecraft would slow down relative to a stationary frame of reference (such as the Earth). This effect was based on two basic assumptions of the special theory of relativity: the special principle of relativity (in different reference frames, all physical laws are the same) and the principle of light speed constancy (the speed of light in vacuum is the same in different reference frames, and has nothing to do with the relative motion of the light source and the observer). Theoretically, when the speed of an object approached the speed of light, time would become slower and slower (the time interval would become larger and larger). For example, in the twin experiment, one group of twins waited on Earth while the other group flew around the Earth in a spacecraft that was close to the speed of light. When the two groups met, the twins in the spacecraft experienced less time than the twins on Earth, which proved the existence of time expansion. However, according to the effect of mass and efficiency, matter with a static mass of less than zero could not reach the speed of light, so in reality, the spacecraft could not really reach the speed of light. However, if the spaceship could reach the speed of light, then theoretically, time could indeed stop inside the spaceship. Under such circumstances, the people in the spaceship would not feel that their time flow had slowed down. It was relative to the Earth observer. The Earth observer would see that the clock in the spaceship was slower than the clock on Earth. Everything in the spaceship seemed to have slowed down. For example, if the person on the spaceship punched twice per second, the clock on the spaceship would show that one second had passed. However, to an observer on Earth, they might see that two seconds had passed on the clock on Earth, but only one second had passed on the clock on the spaceship. This time warping effect was also reflected in artificial satellites. Because the satellite moved faster, the clock on the satellite went slower, so it was necessary to constantly adjust the atomic clock to ensure the accuracy of satellite navigation.

Different types of spaceships had different speeds. China's third-generation high-sea-resistant Wing-in-Ground Ship (sea spacecraft) had a maximum speed of 240 kilometers per hour; the United States 'M80 "Short Sword" stealth speedboat (known as the modern sea spacecraft) had a maximum speed of more than 110 kilometers per hour; China's Xiangzhou No. 1 Wing-in-Ground Ship had a speed of 120 - 550 kilometers per hour.

According to the mass effect formula in the theory of relativity, if any object with rest mass wanted to approach the speed of light, its mass would approach infinity, so the acceleration energy required was also infinite. For example, to make a 100-ton spacecraft reach 90% of the speed of light, the energy required would be the explosive force of several atomic bombs.

In Sea of Thieves, the speed of each sailboat was affected by many factors. When the sails of a sloop were at right angles to the wind (against the wind), the ship would sail faster than if the sails were tilted to either side. The Galleon was one of the fastest sailing ships in direct response to the wind, but in some cases, the Brigantine was faster than the Galleon. If you want to maximize the speed of the ship, there are the following general suggestions: all ships sail at full speed with the wind coming from the stern (just listen to the exclusive full-sail sound effect); single-masted ships sail directly against the wind when the wind is against them, and the sails are at a right angle to the wind; two-masted ships are blown from the side of the wind and the sails are full of the wind; three-masted ships sail at the optimal angle to the wind (avoid the wind).
At present, among the spacecraft made by humans, the United States 'Juno Jupiter probe was the fastest, reaching a speed of 73.6 kilometers per second. The novel " Hundred Years of Spaceship " is equally exciting. Everyone is welcome to click and read it!
A light-speed comeback was when someone returned to their original activity or competition in a short period of time. There were a few related examples. First of all, the LPL professional e-sports player, Uzi, returned at the speed of light after retirement and participated in the competition with his teammates. Secondly, the baseball player, Shohei Otani, quickly returned to the game after his surgery. There was also the tennis player Rafael, who quickly returned to participate in the Qatar Open after recovering from his injury. In addition, the actors Kitagawa Keiko and Amber Heard also returned to participate in the filming and promotional activities in a short period of time. These examples all showed individuals returning to their professions or activities at a rapid pace after facing challenges or injuries.
