Flying speed of the spaceship
Different types of spaceships flew at different speeds. Generally, the speed of spacecraft orbiting the Earth was between 7.9 - 11.2km/s, such as Shenzhou 1 - 9, Tiangong, etc.; the speed of spacecraft flying to the Moon, Mars, or other planets in the solar system was between 11.2km/s - 16.7km/s, such as Chang'e 1 and 2, the Mars probe launched by the United States, Apollo 1, etc. Only the speed of spacecraft flying away from the solar system was greater than 16.7km/s. In the sci-fi movie Star Trek, there was a fictional warp speed used for superluminal spacecraft flight. In addition, when the Shenzhou 19 spacecraft was about 400 kilometers above the ground, its flight speed was about 7.68 kilometers per second. The speed of the return capsule before entering the atmosphere was about 7.8 kilometers per second. When there was only one meter left, the reverse thrust engine would reduce the speed of the return capsule to 8 meters per second. The first cosmic speed of the spacecraft leaving the Earth's surface and circling the Earth was 7.9 km/s, the second cosmic speed of the spacecraft leaving the Earth and flying towards the Sun was 11.2 km/s, and the third cosmic speed of the spacecraft leaving the solar system was 16.7 km/s. There was also the so-called light speed spaceship that had a speed of 30km/s. The novel "Hundred Years of Spaceship" is equally exciting. Everyone is welcome to click and read it!
Is the spaceship flying at the speed of light, time still?
In the special theory of relativity, theoretically speaking, if a spacecraft could reach the speed of light, then from the perspective of an Earth observer, time on the spacecraft would be relatively static. However, for the people inside the spaceship, they did not feel that time had stopped. In their own frame of reference, time flowed as usual. However, according to the special theory of relativity, matter with a rest mass of less than zero could not reach the speed of light, so the spacecraft could not actually reach the speed of light.

Can a spaceship flying at the speed of light still shine?
According to the theory of relativity, the speed of light was the only constant in the universe that was not affected by the state of motion. When a spacecraft moved at the speed of light and turned on its headlights, the light it emitted would form a ray that moved along the direction of the spacecraft's movement. This was due to the relativistic effect. In the spacecraft's frame of reference, light could not exceed the speed of light. Therefore, theoretically speaking, a spaceship flying at light speed could emit light. However, the light wouldn't illuminate the front of the spaceship like under normal circumstances. Instead, it would form a ray of light along the direction of the spaceship. However, it should be noted that according to the theory of relativity, it was impossible for any object to move at the speed of light. This hypothesis was currently only in theoretical discussion.

What is the speed of a spaceship?
The speed of the universe ship varied according to the mission requirements and type. Normally, the speed of a universe ship was around 28,000 km/h. To leave the Earth's surface, one needed to reach the first cosmic speed of 7.9km/s (about 28440 kilometers per hour); to get rid of the Earth's gravity, one needed to fly at 11.2km/s (about 40320 kilometers per hour); to get rid of the solar system's gravity, one needed to fly at 16.7km/s (about 60120 kilometers per hour). Currently, the fastest spacecraft in the world was the United States 'Juno Jupiter probe, which flew at a speed of 73.6 km/s (about 264960 km/h). Voyager 1, launched in 1977, was 17000 kilometers per hour from Earth 40 years ago. The novel "Hundred Years of Spaceship" is equally exciting. Everyone is welcome to click and read it!
A game of flying a spaceship
There were many games to choose from that allowed one to fly a spaceship. Some of the recommended games included Armageddon Crusade, Eve of Star Wars: The Undying Galaxy, Cosmic World, and Planet Leap. These games were all sci-fi space themed mobile games. Players could drive spaceships to explore, fight, and build their own empires in the universe. In addition, there were other space games such as Uninhabited Deep Space, Space Engineer, and Airship Age: Trade Empire. These games provided a rich space exploration and adventure experience, allowing players to realize their dream of flying a spaceship to explore the universe.
1 hour by light speed spaceship
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.

Is there a light speed spaceship in the world?
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 spaceship reaches light speed
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.

Light speed spaceship engine
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.

How to build a light speed spaceship
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.
