length expansion

   The particles inside the particle accelerator fly at a relativistic speed. Therefore, particle accelerators are the best tools for verifying the effects of relativity. However, to interpret the phenomena that appear in particle accelerators as suggested in the current relativity theory, we must make a strange conclusion. Here, the current theory of relativity is a theory that supports length contraction. You may have to conclude that the earth is spinning at 99.999999% of the speed of light. Earth is rotating. The earth is spinning itself one revolution. But if someone claims Earth is rotating 10,000 times per second now, would you agree? I do not think anyone would agree with this. At that rate of speed, perhaps not enjoying ordinary life, everything would have been blown up into space and disintegrated. Let's try the mu-meson story again. Muon, which is created at 10km above the sky, has a very short life span and cannot reach sea level in a classical way. But th...

   Today, I would like to talk about the muon paradox. There are several subatomic particles that are smaller than atoms, such as a μ-meson. It is called a μ-meson, but it is abbreviated to muon. The lifetime of this muon is fixed. The proper lifetime of this particle is 2.2 μsec. It only survives for a very short moment, and then  it collapses into other particles. Cosmic-rays are constantly coming out of space due to the explosion of stars in the universe or the nuclear fusion reaction of the sun. At this time, the cosmic-ray and the earth's atmosphere react to create a muon. Muon's speed is near the speed of light when it falls to Earth. It drops at a rate of about 0.998c. However, even if it falls so fast, it cannot reach the ground because its life is short. If the muon has a lifetime of 2.2 μ sec and a speed of 0.998 c, the muon can run about 650 m from the point where it was created. The point where the usual muon occurs is about 10km above sea le...
