At present, the theory of length contraction in the theory of relativity has many problems. The correct length of the theory of relativity is not length contraction but length expansion.

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...
Black holes are unusual in many ways. Thet have also has a spinning disc, a jet, a Schwartzchild radius, a horizon of events and singularities. But there is one thing that can not be explained in modern science or the theory of relativity. It is the rotating disc of a black hole. Black hole and Ehrenfest paradox The speed at which materials rotate in the rotating disk of a black hole is almost as close as the speed of light. If so, all the materials must be decomposed and discarded by the Lorentz contraction. However, the rotating disk of a black hole certainly exists. It is definitely a contradiction. In fact, these are linked to the famous paradox of the Ehrenfest paradox. [1] Today, we will look at the Ehrenfest paradox. Fig. 1 Paul Ehrenfest Personally, I think Erlenpest paradox is the best of relativity's paradoxes. Other paradoxes seem to be a little simpler than this paradox. The list of people who studied this paradox is very extensive. Ein...
We looked at the Ehrenfest paradox last time. There are two issues in the Ehrenfest paradox. The first assumes a disc made up of an ideal rigid body, but when rotated at relativistic speed, it ruptures. The second is that the perimeter of a rotating body is different from its length when it is stationary. In the last post I looked at the first issue, and this time I want to look at the second issue. For those who have not read the first part, I will briefly introduce this paradox. It is best to read the previous post. Below is a link to the first part. The Ehrenfest paradox part I Rotating disc and length contraction In relativity, objects that run very fast are said to shrink in length. So the official name of this is Lorentz - Fitzgerald Length contraction. It is not 'Einstein's length contraction'. This was born regardless of the theory of relativity. Before the theory of relativity was published, several people experimented to detect ether, but the...
