# The fastest speed in the universe is the speed of light. Is the slowest speed zero? Scientists tell you the answer

Speed is the greatest achievement of human civilization in the age of science and technology. It is with advanced means of transportation and the advantage of speed that human beings can travel all over the earth and explore the mysteries of the earth. Only with the advantage of speed can we break away from the shackles of the earth and go into space to explore the mysteries of the universe.

Speed is not just as simple as our cognition. In many people’s eyes, speed can shorten the space distance and enable human beings to explore more secrets of the universe. However, in scientists’ cognition, speed is powerful energy. When the speed of an object increases, its energy also increases, especially when the speed of an object is infinitely close to the speed of light, Its energy also becomes infinite.

Infinite energy has a threat beyond our imagination. It can easily destroy a planet. Even if a star such as the sun is hit by an object flying at the speed of light, the probability will change dramatically, causing a super explosion, thus destroying a star system.

From this, we can see that the real reason why speed is king is not that the wave has a false name. It is indeed too powerful for us to imagine. Of course, if the speed wants to exert its super power, it needs to be continuously improved. However, according to Einstein’s theory of relativity, the speed of an object with static mass can only be infinitely close to the speed of light, and even the speed of photons can only reach the speed of light, which cannot be surpassed.

Therefore, under the existing scientific theory, the fastest speed of the universe is the speed of light, and the fastest speed must have the slowest speed. What is the slowest speed in the universe? Maybe many people will think that the slowest speed in the universe should be considered? Doesn’t it mean it’s still? So is the slowest speed in the universe really zero? After listening to the explanation of the scientists, I suddenly realized.

Before answering this question, let’s first look at the upper and lower limits of temperature. We all know that there is basically no upper limit for temperature, but it has an obvious lower limit, which is absolute zero, that is, 273.15 degrees below zero. Why does the temperature have a lower limit? In fact, it has something to do with the essence of temperature. Modern science has already known the essence of temperature change from a microscopic point of view, that is, the thermal motion of molecules.

When the thermal motion of molecules becomes more and more intense, the temperature of the object will continue to rise. On the contrary, when the thermal motion of molecules is decreasing, the temperature of the object is also decreasing. There is a limit to the weakening degree of molecular motion, which is static. When the molecule is completely static, the temperature will reach the limit, which is absolute zero. However, we all know that there is no absolute quiescence in the motion of particles, so absolute zero is only a theoretical limit value, which can only be infinitely close and can not be reached.

After understanding the nature of temperature change, let’s go back to the discussion about the slowest speed in the universe. Theoretically, the slowest speed of an object is when it is absolutely stationary. But we all know that there is no absolute static state in the universe. Friends who have studied physics all know that motion is relative rather than absolute. Quiescence is a relative state rather than an absolute state.

When we discuss the motion state of a thing, we need to choose the reference object first. Without the reference object, the motion state of the object can not be determined. At this time, the object is in a chaotic state, like moving but not moving, like static but not static. Only when we choose the reference object, it is meaningful to judge the motion state of the object, and then we can get rid of chaos and enter the real state.

When we see an object standing still on the earth, it is because when we are on the earth and take the whole earth as a reference, the object has a static state. This is a kind of relative static, not absolute static. We see our house standing on the ground, because our house is in a relative static state with the earth as the reference.

But when we go out of the earth and take the whole solar system as the background, you will find that the earth is moving rapidly. The earth motion naturally means that everything on the earth is in motion, and there is no static thing. In the solar system, with the solar system as the reference, the only relatively static object is actually the sun.

Is the sun still? Of course not. If we can go out of the solar system, stand outside the solar system and take the whole galaxy as a reference, you will also find that the whole solar system is moving, including the sun. After reading these, I believe many friends also understand what is relatively static. There is no absolute stillness in this universe. Even if we can find things that are still in the universe, it is relative stillness with the whole universe as the reference.

If one day in the future, human beings can walk out of the universe, they may also find that our whole universe is still in motion relative to the space outside the universe. The above is our macroscopic analysis of the relative static state of an object. If we analyze it from the perspective of quantum mechanics, is the velocity also relatively static?

The answer is yes. No matter from macro physics or quantum mechanics, the static state of matter is relative. This truth applies not only to the macro world, but also to the micro world. It can be seen that the discussion of the slowest speed in the universe put forward by a friend has certain logical errors. The correct answer to this question is that there is no slowest speed in the universe, only slower speed.

Of course, the cognition of speed is still relatively limited. Whether the speed theory in our cognition is correct or not still needs the continuous research and exploration of future scientists. In particular, the fastest speed in the universe is the speed of light, which may be a wrong conclusion. If the speed of light is the limit of speed, is it meaningful for human beings to develop science and technology and hope to explore the whole universe? Security is meaningless.

The vast universe is too big for us to imagine. If the speed limit of a spaceship is the speed of light, we can’t even explore the galaxy, let alone the whole universe. Without the advantage of speed, the future development of human beings and ecological resources will be in trouble. One day, human civilization will disappear in the universe due to the depletion of resources.

It can be seen that the fastest speed in the universe may not be the speed of light, it may be the same as the upper limit of temperature, it is a concept without absolute value. Through a lot of observation and research, scientists have at least found that the expansion speed of the universe is far faster than the speed of light, indicating that the fastest speed in the universe is not the speed of light, and the expansion of space can easily exceed the speed of light. In the future, scientists may be able to explore the mystery of space through research, so that human beings can break through the speed limit of light and enter the era of superluminal speed. We are looking forward to this day.
