As we all know, the speed of light is the fastest speed in the universe, but at the same time, the speed of light is quite slow in the universe.
At the same time, someone once asked Albert Einstein: "What would happen if someone drove a spacecraft faster than the speed of light?"
How did Albert Einstein answer?
Is faster-than-light possible?
1. The slowness of the speed of light.
In our daily lives, we want to do something, such as getting up, cooking a meal, going out, these are all small things that we can do at our fingertips, unless you really don't have time.
So what are the speeds we can expect?
Generally speaking, the speed that most people are satisfied with is the speed of physical movement, and the fastest speed of walking is about 6 m/s, and the fastest speed of running is about 18 m/s.
Further up, the leap can reach 40 m/s, which many animals cannot run, while the fastest human speed continues to innovate with the continuous improvement of the use of tools, such as skiing, grass skiing, running, etc., can reach 50 m/s.
This kind of speed, we sometimes feel that it is not enough, and want to use motor vehicles, and the speed of motor vehicles has been able to reach 200 m/s, high-speed rail is faster, can have 350 m/s, the fastest when the plane ascends can reach 200 m/s, and the maximum speed of people when skydiving reaches about 70 m/s.
Even if it is a rocket, the fastest speed of human beings cannot reach the speed of light, which is 3000000000 m/s.
Therefore, it is impossible for human beings to reach the speed of light under the current technological conditions.
So how fast is that?
There is a counter in our daily life, that is, the stopwatch, which is a tool to calculate the time spent, if the speed of the stopwatch is used to calculate the speed of light, 1 second to run 190 laps, then the speed of light can run 7.5 laps, the length of the circle is 2πr, that is, 3.142149.6*10^9=94 billion kilometers.
The speed of light can run 310,000 laps in 1 hour, that is, 94 billion kilometers/310,000 laps = 300,000 kilometers/lap
So we get a typical solar system radius of 5 trillion kilometers, and our light-speed stopwatch can run 157.9 billion laps in 1 hour.
If the speed of light is on this stopwatch, it can run 157.9 billion laps, that is, 4.39 million laps in 1 second, and 1 revolution in 6 seconds, 1 light year is 946.1 billion kilometers, and if you use the speed of this stopwatch to run 1 revolution, it will take 6 seconds.
However, in the universe, the speed of light is not too fast.
For example, it takes 1.3 seconds for light to pass from the earth to the moon, it takes 8.3 minutes for light to reach the sun, and it takes 5.5 hours for light to reach Pluto, but the distance of light from the earth to the sun, the distance of a month, the distance of an astronomical unit is 15 billion kilometers, if the light travels a month's distance, it needs to run 10,000 times with this stopwatch, that is, the speed of light is also relatively slow on this scale.
So what are the other magical properties of the speed of light?
The most amazing thing about the speed of light is that it doesn't change.
In our normal motion, the speed is subject to change, and it happens all the time, unlike the speed of light, the speed of light will never change, which is also the conclusion that Einstein came to when he proposed the special theory of relativity.
The speed of light can neither exceed nor slower than the speed of light, so is there anything that might be questionable about the speed of light itself?
The speed of light is only a constant, there is no beginning and no end, but the speed of light also has time forward, space backward, so what is the physical law under the speed of light?
Albert Einstein believed that the speed of light is an extreme speed, an extreme, and at the same time, the speed of light is a speed that is greatly ignored.
Visually, if the speed of an object is greater than the speed of light, the object becomes an invisible state, because the light energy around it is overtaken by it, and the highest speed of energy in the universe is the speed of light.
The speed of light is omnipotent, and there is an assumption that if there is a spaceship that is close to the speed of light, and all the technology can't figure it out, can there be any other way to do it?
Albert Einstein told him that he could use the curvature of time.
2. Traveling faster than light.
We can drive through wormholes and the like, but this method is not practical at the moment, but it may be used because there are many aspects that have not yet been explored, and this is the beauty of science.
Italy's Okubieri also designed a spaceship, this spacecraft is not propelled by reaction, but more like a stone, pushed from the ground to the top of the mountain, you can slide down the mountain, the process of sliding down is the curvature of time, from the ground to space, is the process of sliding, this is called "curvature drive".
This kind of spaceship can be accelerated all the time, all the time accelerating, but the human body can't stand it, and it may become a skeleton when it accelerates for the second time, so this kind of spaceship is specially used for research, whether it can be done or not, human beings don't dare to gamble with their own lives.
If the spacecraft wants to be driven by curvature, it must first have curvature, and curvature still exists in the physical world, which is "negative energy", which is called "sliding friction" in tribomechanics, negative energy is a substance that can turn back space-time, and when there is negative energy, curvature can be generated.
Is it possible for negative energy to exist?
Okubieri said yes, but couldn't give any opinion, physicists have tried, but unsuccessful, some say that negative energy can be realized, but special conditions are needed, and there is also a theory that negative energy does not exist, which has become a scientific mystery.
So can the speed of light be reversed?
The speed of light does not change according to the special theory of relativity, light travels in a vacuum, if the speed changes, the energy changes, so the speed of light will never change, the current speed of light is 1 light year / year, which is already the extreme, in the universe, the speed of light is omnipotent and invincible, but there are also people in the scientific community who have come up with a way, such as a wormhole.
A wormhole is another kind of space tunnel that connects different universes and galaxies, which is like going directly from one place to another on Earth, and this kind of tunnel is a wormhole.
Wormholes can shorten the distance between two points and can meet our faster-than-light needs, but the structure of wormholes is unknown and no one has discovered them yet.
3. Speed above the speed of light.
At the speed of light, we cannot explore the magic and mystery of the universe, and human beings are still in the exploration stage of the universe, so it is possible to explore many new fields in the future, and with the progress of science and technology, we may be able to break through the limit of the speed of light.
In our lives, there is a substance that allows a bullet to penetrate glass, and that is a spring, which is connected to the piston at one end and the piston at the other end, and when the piston is moving, the spring becomes longer, and the same is true for electrons.
The electron is a piston connected to the nucleus of an atom, and when the electron is active, it acts like a spring, which acts as a medium of force, which excites the plasma and produces a spring of the medium, which swings the electric field lines, which can create a vortex called an "attraction wave".
The attraction wave acts like a ship, it will compress the water wave behind the water and push it forward until the sea is reversed, which is what we often call a "vortex", and when it is shaken, the water wave goes back.
When an attraction wave is excited, the electrons behind it, like a wave of water being shaken, emit light, and when this luminous photon transmits information, it is like a ship, and it will carry information along the medium like air.
This way of communication is like a person, people walk too fast, people walk too slowly, people walk almost, just like a pair of feet piercing and pushing, the front and rear feet run about the same, that is, people walk too slowly, Zhang Shaohan sang in the song "Time is slow".
However, when playing video games, when we play games like "Legend of Tianhe", the time in these games follows the rhythm of the game, and if the player suddenly disconnects from the Internet, time will stagnate, such as team time, or level up, or gain experience, etc.
In case time slows down, game time slows down, and that's how the light roll works.
Another property of "attraction wave" or "vortex" is that it pulls other electrons, and when there is an "attraction wave" between two electrons, these two electrons will fall into the trap of attracting the wave and will enter "quantum entanglement".
Quantum entanglement, equivalent to the medium of transmitting information, between two each other, the transmission of information without a medium, between two electrons can be carried out the transmission of information, so it is undoubtedly a faster-than-light mode of communication, the disadvantage of quantum entanglement is that if there is no medium, then the information between the two electrons is transmitted in time, then in time, it is no longer sequential, that is, for example, this morning, one person delivers breakfast, one person sends a courier.
If you change your time, this morning's people will be sent in the morning, and this morning's people will be sent in the afternoon, then this time will be chaotic, this is in the Internet era, the right time, you need the right time.
If human beings can break through the limitations of time, then the superluminal speed in the concept is no longer an illusory existence, and the life of human beings may change greatly in the future.
epilogue
The imagination and breakthrough of human beings about the speed of light is the inevitable product of the exploration of all things in the universe and the progress of science and technology.
Wormholes and curvature drives, as well as Okubieri's spacecraft, and then to the challenge of negative energy, all demonstrate the in-depth discussion and attempt to transcend the speed of light and explore the laws of the universe with the innovative thinking and scientific and technological efforts of human beings.
At the same time, the problem of negative energy also demonstrates the in-depth discussion and challenge of energy and material properties in scientific research.
As a phenomenon that transcends time and space in classical mechanics, quantum entanglement may affect the physical properties of matter and the speed of information transmission, and also bring people to rethink the concept of information transmission and time.
In the future, science and technology will continue to innovate, the speed of space will continue to improve, and chemical propulsion technology may be replaced by nuclear fusion, which will inevitably bring about fundamental changes in the way and speed of space exploration, and will also open a new era of space exploration for mankind.
