When can humans fly?
The first human flight was on November 21, 1783, when a hot air balloon designed by the French brothers, Joseph Michele and Jacques Mongofier, took off over Paris. However, this was a hot air balloon flight. In 1809 - 1810, Sir George Kelly of the United Kingdom published "On Air Navigation", which determined the four forces of flight and designed the first manned glider. On September 24, 1852, French engineer Henri Gifard piloted an airship to complete the first flight with controllable power. On December 17, 1903, the Wright brothers completed the first controlled, sustained airplane flight. In November 1907, the French engineer Paul Kenu first tested the rotary-wing aircraft, the predecessor of the helicopter. From these historical processes, humans began to gradually explore and realize different forms of flight in the 18th century. With the continuous development of science and technology, flight technology also continued to improve. Today, humans already had a variety of advanced aircraft, such as jet passenger aircraft, fighter jets, etc. Flight had become an important part of modern transportation and aerospace exploration.

Humans can fly
Humans had gone through a long exploration process to achieve flight. In the early days, people tried to obtain lift through gases lighter than air, such as balloons. On November 21st, 1783, the French brothers 'hot air balloon, Mongofia, successfully flew with animals. Then, the competitor's hydrogen driven balloon also flew. After that, balloons evolved into airships with the support of various equipment. In 1900, the golden age of airships was ushered in. Zeppelin airships were the representative of that time. They were used for war, travel, and many other purposes. However, due to the flammation and explosiveness of hydrogen (at that time, helium was rare and the United States restricted the export of hydrogen, so they had no choice but to choose hydrogen), the golden age of airships came to an abrupt end after the Hindeburg airship disaster in 1937. In the exploration of aircraft heavier than air, the German inventor Otto Lilienthal had achieved gliding flight many times, and the French engineer Clement Adel successfully verified the invention of the aircraft in 1890 but missed the title of "first aircraft" because it was listed as a state secret. In 1903, the Wright brothers created the first aircraft with an engine in human history,"Flyer 1," and completed the first continuous, powered, and controllable flight in human history. In 1950, the world's first turboprop jet passenger plane, the British Viscount, was put into use. In 1958, the American boeing 707 entered the route to announce the beginning of the civil jet aviation era. In 2011, China's J- 20 successfully made its first flight. In 2017, China's C919 successfully made its first commercial flight on May 28, 2023. In addition, humans also explored the universe by launching unmanned probes in outer space, such as the Voyager 1 launched on September 5, 1977. It was currently the farthest man-made aircraft that humans had flown. It had flown 24 billion kilometers away and was flying alone toward the center of the Milky Way.

Can humans fly?
Humans didn't have the natural physiological structure to fly like birds or insects, such as wings and lightweight bone structure suitable for flight. However, with the help of various flying tools, humans realized their dream of flying. Early humans used hot air balloons and airships to fly. In 1783, the first manned hot air balloon flew, and in 1852, a controllable airship flew. Then, in 1903, the Wright brothers achieved the first controlled and continuous flight of the aircraft. The development of the aircraft continued to evolve, from the early simple aircraft to the modern jetliner and many other types. In 1950, the world's first turboprop jet passenger plane, the British Viscount, was put into use. In 1958, the United States 'boeing 707 entered the air route and opened the era of civil jet aviation. In addition, in 1907, helicopters appeared. In addition to flying in the atmosphere, humans also launched aircraft into space, such as the Voyager 1 launched in 1977, which had flown a long distance in space.

Can humans fly at light speed?
As of now, humans had yet to achieve light speed flight. Although scientists had been exploring faster flight technology, according to existing scientific theories, especially Einstein's theory of relativity, no matter could exceed the speed of light. This theoretical limitation posed a huge challenge to achieving light speed flight. Currently, the fastest interstellar probe, Voyager 1, took more than 40 years to fly across the solar system. It was still very slow compared to the speed of light. However, with the continuous development of science and technology, there were still many uncertainties about whether this limit could be broken in the future.

Why do humans fly into space?
There were several reasons why humans flew into space: 1. Curiosity: Humans have curiosity, which is an important driving force for the development of human civilization. Since ancient times, humans had been full of imagination about the vast and mysterious sky. This curiosity had prompted many people to constantly study it, resulting in today's aerospace achievements. 2. Resource development: Human development is full of infinite possibilities, but Earth's resources are limited, so going to asteroids to develop minerals has become a feasible method. 3. Find a new home: Humans must prepare for the rainy days and find a new home for themselves. The famous scientist Hawking once warned that humans must undergo interstellar migration within 100 years. Otherwise, they would face many dangerous factors, such as nuclear war, biological warfare, climate crisis, invasion of alien civilizations, asteroid impact on Earth, etc. These factors could lead to the extinction of human civilization. 4. It was helpful to understand the universe, the Earth, and humans themselves: Compared to the entire universe, humans were very small, and human history was very short in the time scale of the universe. It was difficult to understand the development of the universe, the solar system, the Earth, the development of mankind, the origin of life, and many other issues with such a small time and space scale. Only after humans left Earth would they be able to better understand the developments in these areas. 5. To improve life and scientific research needs: Flying into space is not only to realize the "flying dream" that the China have continued since ancient times, but also to use space to improve life and carry out scientific research that is beneficial to mankind, such as space breeding. 6. The general trend and the cost will be reduced: With the development of science and technology, the cost of entering space will become lower in the future, and it will be as convenient as taking an elevator.(For example, if the space elevator technology has a breakthrough, its cable can be made of carbon fiber material with a diameter of less than 2 millimeters and 50 times thinner than a hair. Although this cable is soft, its hardness is far beyond steel. Once the technology is broken, it will greatly facilitate human access to space.) This makes it a general trend for humans to enter space. The novel "Hundred Years of Spaceship" is equally exciting. Everyone is welcome to click and read it!
Why do humans desire to fly?
Humans longed to fly mainly for the following reasons: 1. ** Yearning for freedom **: Freedom is the hope of not being bound too much. Perhaps a long time ago, when human ancestors saw eagles soaring in the sky, the earth suddenly became a kind of restraint, thus producing the desire to fly. 2. [Curiosity and thirst for knowledge: Humans have a blank understanding of most of the attributes of the sky, and curiosity makes humans instinctively want to add the attributes of the sky to their own understanding.] As mankind's exploration of the sky deepened, the concept of the sky continued to expand, from Earth to the moon, to the solar system, and then to the starry sky and the universe. Curiosity about the sky and the desire to fly were the driving forces for humans to explore step by step. 3. " Expanding human thinking ": Human thinking is often constrained by real-life experience. Exploring space requires solving many professional problems, such as materials, power, shape, etc. This urges scientists to be innovative and break through past experience. Most of these technologies invented due to space exploration would be converted to civilian use and ultimately benefit mankind. 4. [Transcending Self-limitations and Controlling Magical Power]: In the minds of ancient humans, birds could fly with wings, but humans could not fly without wings. Flying was the transcendence of self-limitations, and it also symbolized the control of magical power. 5. The desire to explore the unknown: The three classic ultimate philosophical questions, such as " where do we come from, who are we, and where are we going?", may need to be slowly discovered through the exploration of space and even the universe. Earth's resources are limited, and humans need to find new sources of resources for the future. This is also one of the reasons for exploring space.

How long does it take for humans to fly 1 light-year?
For example, the Voyager 1 probe, which was currently the furthest flying probe, had a speed of about 17.062 km/s. It would take about 17500 years to fly at this speed for one light year. The New Horizon probe launched in 2006 had a speed of 23.33 km/s. It would take more than 12800 years to fly at this speed for one light year. If one were to calculate the speed of common vehicles on Earth, it would take 18 million years to drive a car at a speed of 60 kilometers per hour, 3.6 million years to take a high-speed train at a speed of 300 kilometers per hour, and 1.2 million years to take a plane at a speed of 900 kilometers per hour.
