The speed of motion can reach and exceed the Speed of Light, can’t it?

According to human experience, it seems that a flash of Light emanating from somewhere can be immediately seen by an observer beyond a certain distance. In terms of communication, emitting a flash means emitting a signal while a flash means receiving a signal. Are signaling and receiving at the same time? If it is at the same time, the speed of Light must be infinitely large: if it’s not simultaneously, the speed of Light is limited.

Three hundred years ago, the Danish astronomer Olaus Roemer, through observing the eclipsed period of Jupiter’s satellite, concluded that the speed of Light is limited. The speed of Light that he measured is C = 2.77 x 1010 cm / s. In 1849, James Brley of England, taking advantage of the cogwheel method, successfully measured Light’s speed. Later, through many improvements, it was determined that the speed of Light in a vacuum C = 2.997925 x 1010 cm / s, that is, in a second, Light can circle the Earth 7.5 times. Light travels at such a high speed, at the daily viewing distance, the time it takes for Light to pass, which is so small that people often mistakenly believe that the Light is signaling and receiving the signal at the same time. Currently, in everything that exists in the world, the fastest speed of motion is the speed of Light in a vacuum; no other object’s speed of motion can reach and exceed it. Why?

It turns out that discussing Light’s speed is not just a matter of speed, but also what time and space people have to use to perceive time and space evolution of nature and the Universe. Einstein built a fundamental difference between classical physics founded by Newton and relativity. Newton said that time is absolute. From the ancient past to the infinite future, time always passes in the same way. Space is also absolute; measuring the length of space, large and small, is always fixed, regardless of time or space, and can not be affected by the motion state of an object. Also, Newton said that the mass of an object is also a constant physical quantity. No matter the state of motion, mass can not be changed.

From his view of the three basic physical quantities: space, time, and mass. Einstein drew completely different conclusions from Newton. He said that these quantities are not absolute but they’re relative; that is, they are closely related to the state of motion.

If there is a ruler with a stationary length Lo when it is evenly moving in the ruler’s direction at speed v, its length is measured 1 = W-4; in motion is: where c is Light’s speed. Because the speed of Light is very large, so L is smaller than L0; furthermore, the higher the speed of motion is, the more pronounced the shortening of L is. Through calculation, you will notice: a straight 1 m long when standing still, when the movement speed reaches 0.9 c, the length is only 0.436 m.

Likewise, if a watch participates in linear motion at speed v, then the time distance t0 at rest will turn into t in motion. When stationary, the time interval for the whole day is 24 hours, when the watch’s movement speed reaches 0.9 c, so it takes up to 55 hours! The time gap stretched out more than doubled!

Volume is also relative. According to Einstein’s theory, the object has a mass equal to 1 kg at rest; when the motion speed reaches 0.9 c, the mass increases to 2.29 kg. The length shortens, the clock slows down, the volume increases, is it true that those things will happen? In many experiments on high-energy physics, scientists have completely verified this kind of relativity effect. Because the speed of motion of an object in our daily lives is much lower than the speed of Light. Although the relativity effect still exists, the change caused because it is too small, it isn’t easy to recognize.

For example, when the speed of motion v of the object is equal to or exceeding the speed of Light, what will be the results? Obviously will become a zero or a virtual number. Then, objects of any length at stationary, when in motion will shorten to zero or imaginary number, time distance At and mass m, when the motion will become an extremely large or imaginary number. Up to now, such conclusions have not been able to prove its rational existence. Thereby, it can be seen that an object has a fixed length, a certain stationary mass, and moves in a certain time interval t; its speed can only approach the speed of Light, without how to reach and exceed the speed of Light. That is the highest limit of all the motion speeds of an object in modern physics.

I used to look up at the sky when I was a child and wonder what's in those stars. Growing up, when I had the opportunity to contact the source of human knowledge, I had more knowledge about the universe, the natural world, and created laws. Being the founder of Wikiwap is where I can share my understanding of the world around me in a simple way that readers can access knowledge like a child. You and I are parts of the world; life will always be beautiful.
