1. The theory of relativity has a very important statement:
The observed results are in good agreement with the calculated results. Please note that the medium of observation here is light or electromagnetic waves, and its propagation speed is 300,000 km/s,
We will use "detection" instead of "observation" later, because the measurement does not necessarily have to rely on light or electromagnetic waves, perhaps on sonar, etc.
2. Let's take a look at several sensors evolved by organisms: and the corresponding speed
1) The sound wave receptor, which later evolved into the ear, the speed of sound is 340m/s
2) Photoreceptors, which later evolved into eyes, light or electromagnetic waves, 300,000 km/s
3) Magnetic field receptors are only found in some animals such as pigeons. The propagation speed of the magnetic field may also be the speed of light (electromagnetism is not separated), ibid.;
4) Virtual receptors in the spiritual world, the speed of detection of matter in the spiritual world can be infinite, because the brain can think of 10 billion light-years away in 1 second, or even the edge of the universe, so according to the definition of speed, speed = distance/time, so it is gigantic.
3. The Lorentz transformation is actually a time expansion factor introduced when the observed medium is light or electromagnetic waves, in order to make the calculation results conform to the corrections made to the observed results.
4. In the blindfolded bat world, that is, when the detection medium is sound, the speed of light c in the Lorentz transformation needs to be replaced by the speed of sound in the environment. At the same time, remember that when detecting, you cannot use any medium that exceeds the speed of sound, so all electronic instruments cannot be used. You can only use sound waves to detect, otherwise it will not work. At this time, the principle of constant speed of sound also exists. In order to make the calculation results consistent with the acoustic detection results, it is necessary to convert the Lorentz transformation into Replace the c with the speed of sound.
Likewise, if testing in water, replace it with the speed of sound in water, and remember not to use any electronic instruments.
5. When the detection occurs in the brain, replace the c in the Lorentz transformation with infinity. At this time, it will be found that the Lorentz transformation becomes the Galileo transformation. That is to say, the Newton-Galileo transformation is in line with the thinking of the brain.
6. Therefore, from a biological point of view, the special theory of relativity actually means that when the detection medium is light or electromagnetic waves, in order to make the calculation results consistent with the detection results, it is just a mathematical transformation, not really time dilation. Well, time dilation is just an effect.
7. Whether the propagation speed of gravitational waves exceeds the speed of light is still controversial, because people have not invented instruments that can use gravitational waves to detect.
However, I personally think that the propagation speed of gravitational waves may exceed the speed of light, because the universal gravitational formula F = G*m1*m2/r^2 , there is no speed in the formula, that is to say, the speed does not affect the gravitational force. The expansion speed of the universe exceeds the speed of light, and the gravitational force of the stars in it exists at any time. Therefore, it is speculated that gravitational waves may exceed the speed of light, but it is difficult to confirm.
8. In the future, if a medium with a faster propagation speed is discovered (assuming that the speed of gravitational waves exceeds the speed of light), and people also invent receptors that can use this medium (similar to photoreceptors-eyes, sound wave receptors-ears), then everyone It is natural to understand the special theory of relativity and its limitations.
9. If a creature has the ability to use gravity to locate itself (like people use their eyes to see and ears, and pigeons use the earth's magnetic field), then gravity detection equipment will also be produced (military modern stealth fighters will have nothing. Escape), then the special theory of relativity will be self-defeating.
Appendix:
1) General formula of Lorentz transform (it is assumed that the propagation velocity of the detection medium is constant)

2) When the observations take place in a vacuum or air (electromagnetic waves or visible light), the Lorentz transform

3) When using sound wave detection, in order to make the calculation results in good agreement with the detection results, it is necessary to assume that the speed of sound is constant, provided that no electronic instruments are involved, otherwise it will not work.
4) When "detection" happens within consciousness, (i.e. when the brain is simulating)
