In the process of exploring the world and the universe, people should not only have the speed of time, but also the speed of light in the universe. Only with the continuous improvement of speed and continuous research, can we make progress in the process of exploring the world.
Many people think that from the perspective of human beings, speed refers to some modes of transportation. From the initial walk, to the later carriage, to the car, and even now the high-speed rail and aircraft, the travel speed of human beings is constantly improving, and now human beings have entered a new era. Speed is indeed a standard to promote the progress of civilization in an era.
The fastest speed in the universe as we know is the speed of light, and this fastest speed is related to time. No object can get rid of the concept of time when it reaches its limit. So is the speed of light. Do we think that the fastest speed of light is only 300000 kilometers per second?
Many people will ask, “what do you think is the fastest speed in the universe?” The speed of light reaches 300000 kilometers per second. How can humans surpass it? Coming out of the solar system? Many people’s answer is light. When describing the speed of things, many people will also call it the speed of light, which can reach 300000 km / s. People can see light every day, but they can’t touch it. This is a very unreal definition. Have people lived for hundreds of years? What is light?
In fact, it is not clear to scientists what light is. If we look at the nature of light, is light a particle or a wave, what is it? Moreover, scientists do not have a clear conclusion. Newton once put forward a theory, that is, the particle theory. Many scientists also believe that, and Newton also put forward the idea that light is a particle.
But with the passage of time, this theory was quickly overturned, and many people said that light is a wave, but the propagation of wave needs medium, so what is the medium of light propagation in light? Is there any air? The speed of light is 300000 kilometers per second. What is light? Newton is different from scientists! In fact, because light can also propagate and see light in vacuum, it is wrong to say that this theory. Empty scientists have studied the nature and characteristics of light. Of course, there is no clear conclusion yet.
Therefore, people have been pursuing speed, the speed of light, but the speed of light is nothing in the whole universe, because the universe is so huge, beyond our imagination, the speed of spaceship has reached the speed of light, which can only show that the development of human beings is very fierce, has developed to the level of interstellar civilization. To explore the entire galaxy, even the solar system, humans need to travel faster than light.
