Planck's length is 1.6x 10-35 meters, which is the smallest distance unit in physics. Planck length, a unit of distance, is very important because it is the only physical measurement unit that can be defined by five physical universal constants.
The smallest distance unit in the world is Planck length. It is1.6x10-35m, which is the smallest distance unit in physics. If we continue to shrink, it is equivalent to enlargement, for example, to 1000 times Planck length, which is equivalent to enlargement to 1000 times Planck length.
The smallest unit of length in the world is also the smallest measurable length, which is roughly 1.6? 10 to the-35th power meter is 1.6? 10-33cm, that is, 0.0000000000000000000000016m, with a decimal point of ***36, is difficult to express in words. Haul in physics is expressed as 1/ the size of a proton. This measurement is mainly used to measure the quality of black holes produced by physical collisions, because objects will produce black holes at the moment of collision, and to measure an object, we need to reflect light to obtain data, and light is affected by black holes. Swallow it? Will affect the measurement accuracy, and Planck length can be used to calculate the error caused by the black hole in the measurement, and the quality of the largest black hole in the world depends on it.
Planck length and Einstein's theory of relativity are complementary. With the development of modern physics, there is no unit of measurement that can exceed Planck's length for the time being, because once Planck's length is lower than 1, the theory of space-time relativity will fail, light and time will be distorted in this space-time, and the data in this space-time will lose its original meaning and become irregular.
As one of the important theoretical foundations of quantum mechanics, Planck length is not common in our daily life, but this unit of measurement has witnessed the development of modern physics. In the era of invisible quantum as the mass unit, Planck length has made mankind take a big step forward in finding the origin of the universe.
