<> our world is essentially made up of many elementary particles "piled up" under different physical laws, neutrinos are not among the "building blocks of the universe".
At the end of the 19th century and the beginning of the 20th century, the physics community was in a period of vigorous development in the process of alternating between old and new theories, in which the research related to radioactivity not only made mankind aware of the deepest part of matter, but also made mankind aware of the energy of the sun** and the huge energy inside the atomic nucleus.
In the decay process of radioactivity research, physicists found that the energy before and after the decay process is not conserved, and a part of the tiny mass always becomes inexplicably without a trace, this anomaly once made the physics god Bohr doubt the correctness of the "conservation of energy", but Pauli, who was also a physicist at that time, believed that the conservation of energy was right, and it was Bohr who was wrong. <>
Pauli believed that part of the mass "missing" during the decay process was caused by "a particle that has not yet been discovered", but this particle is extremely small and extremely fast and barely reacts with any matter, so it is difficult for instruments to detect, and the physicist Fermi later named this "unknown particle" neutrino.
It wasn't until 1956 that physicists officially discovered neutrinos, and decades after that, research on neutrinos is still in full swing, but the so-called "neutrino faster-than-light" in Italy a few years ago is just an oolong caused by the lack of cables. <>
Theoretically, there are trillions of neutrinos passing through the earth and passing through each of our bodies every second, but the neutrino itself is only one hundredth of the mass of an electron and the speed is close to the speed of light, and more importantly, neutrinos are neutral particles, and they can ignore the influence of electromagnetic force if they are not charged, which is one of the reasons for its high penetrating power, but neutrinos do not "come and go without a trace".
Physicists** neutrinos will be affected by weak forces when passing through "pure water" and react with hydrogen nuclei, so Japan's "Super Kamiokande Detector" used 50,000 tons of pure water to conduct neutrino research.
At present, except for black holes, there is nothing that can block neutrinos, so "neutrino communication" is also a frequent visitor to science fiction, theoretically a beam of neutrinos that carry information after debugging can transmit information to any part of the universe losslessly.
-
The phenomenon of neutrino faster-than-light anomalies is true, and the phenomenon of black holes can block the phenomenon of "neutrino faster-than-light anomalies", and nothing else can stop it.
-
A neutrino is a particle with a mass close to 0, theoretically it can travel through the earth, but it can travel through the earth, it is based on the fact that the earth's material has a gap, just like there is a gap between two atomic nuclei, and it walks through this gap, as for whether it can exceed the speed of light, there is no official conclusion.
-
The phenomenon of neutrino superluminal speed anomalies is of course true, and in the case of such anomalies, different changes will occur, and the collision of the earth with these speeds of light will cause disasters.
-
Really, this particle can travel freely, very freely, and can even travel through the speed of light, which may also provide us with the possibility of developing a time machine and traveling.
-
The phenomenon of neutrino faster-than-light anomalies is real, because there are actual data to test this artifact, and it should be derived from the reality of proton decay, the reality of neutrinos and magnetic monopoles, etc.

On September 24, 2011, European researchers discovered the inexplicable phenomenon of neutrinos exceeding the speed of light, a phenomenon that violates Einstein's theory of relativity. An experimental device called Opera at the Gran Sasso National Laboratory in Italy received neutrinos from the renowned European Center for Nuclear Research (CERN), 730 kilometers apart, and the neutrinos "traveled" over this distance 60 nanoseconds faster than the speed of light (1 nanosecond equals one billionth of a second).
Antonio Iratitato, of the University of Bern in Switzerland, who participated in the experiment, said he and his colleagues were so shocked by the results that they observed the phenomenon 10,000 times and carefully considered the influence of various other factors in the experiment, and decided to make it public.
Albert Einstein's special theory of relativity, proposed in 1905 and hailed as "the cornerstone of all theories in modern physics", holds that no matter can move faster than the speed of light. The neutrino superluminal phenomenon is of great significance, and the entire system of physics will be reconstructed as a result, which will change the understanding of how the universe works.
Neutrinos at the speed of light verified the new theory proposed by Chinese scientist and vice chairman of the new Nobel Prize jury committee George Muyeshi to modify Einstein's theory of relativity, which was submitted to scientific research institutions around the world ten years ago (Chinese title: "Beyond Einstein - The Universe is Understandable", "Beyond Einstein - Exploring the Origin of the Universe"). George experimentally found the primitives of matter that are more fundamental than particles, concluded that they travel faster than light, and proposed the "mass-energy equation" of faster-than-light matter, explaining the energy of black holes and quasars that are more than a dozen orders of magnitude higher than the nuclear fusion energy**, and pointing out the limitations of Einstein's "mass-energy equation".
And experiments have proved that superluminal speed does not violate the "law of cause and effect", and high sub-light speed can slow down individual time, but superluminal speed cannot go back to the past, because there are many time dimensions in the universe, and these time dimensions are independent of each other, and time travel is unrealizable. While revising Einstein's special theory of relativity and general relativity, George also proposed a relatively complete upgrade theory, that is, the theory of quantum gravity. It is worth noting that his new theory did not completely subvert Einstein's special and general theories of relativity, but only made major revisions, pointing out the limitations and scope of application of the theory of relativity, just as Einstein revised Newton's theory of gravity.

Much of the speculation is that neutrinos travel that distance through some kind of shortcut (e.g., a high-dimensional space......But Hawking said he didn't believe in the results and still supported the theory of relativity.
-
Explore ghost particle neutrinos, from how they were proposed to their discovery and confirmation that neutrinos are really faster than light.
-
Neutrinos just travel some distance less than light.
-
The universe is expanding, the speed of light is increasing, light is constant from one end of the universe to the other, the universe is considered unchanged for a certain period of time, the calculated speed of light remains unchanged, and some constants are now slightly different from Einstein's time and have not been discovered. It has yet to be proven, and evidence is lacking.
-
There is no absolute, and Einstein's theory of relativity is not necessarily the most complete law, just as people thought that Newton's classical theory of mechanics was the absolute truth, but it was overturned and improved by Einstein. Neutrinos are faster than light, and it can only be said that this is the law of existence in the universe, but it has not been discovered until now, just like the theory of relativity was discovered by Einstein, so I think we should not ask why it can be accelerated to the speed of light, but should think further: Is Einstein's theory of relativity not perfect?
Is there another view of time and space that has not been discovered?
-
The speed of light is unsurpassable, neutrinos just travel some distance less than light, and Einstein is not wrong, but it is not comprehensive enough.
-
If the time machine appears, I'm afraid the world will be in chaos.
-
Because the line is not plugged in, hahahahaha.

Neutrino experiments have been done many times, and the possibilities are becoming more and more acceptable, of course, the science is rigorous, and it is still too early to draw conclusions, but it is already possible to boldly imagine such possibilities.
I read a little bit of relativity articles, as well as Hawking's popular science books, and these theories have always been based on the speed of light as the ultimate speed, which seems to me to have been the basis of the theory since the advent of relativity.
If there is faster-than-light, the entire physical system will be reshuffled, and some of the contradictions that have existed in the very small and very large problems will be reorganized. The correctness of the theory based on the speed of light and the proven facts cannot be denied.
In my opinion, the centrality of theories based on the speed of light will change, just like Newton's creation of normal-speed physics, and perhaps the study of physics at the speed of light will open up another part of the world that we do not know.

In 1956, Leynes and Cowan directly observed neutrinos in experiments, and Rheins won the Nobel Prize in 1995.
In 1962, Lederman, Schwartz and Steinberg discovered the second neutrino, the Miu neutrino, and won the Nobel Prize in 1988.
In 1968, Davis of the United States discovered the disappearance of solar neutrinos and won the Nobel Prize in 2002.
In 1985, the Japanese Shengang experiment and the American IMB experiment discovered atmospheric neutrino anomalies.
In 1987, supernova neutrinos were observed by the Kamigang experiment in Japan and the IMB experiment in the United States. Japan's Masatoshi Koshiba won the 2002 Nobel Prize.
In 1989, CERN proved that only three neutrinos exist.
In 1995, the LSND experiment in the United States discovered the possible existence of a fourth species of neutrino, the Sui neutrino.
In 1998, the Japanese Super Shengang experiment discovered the neutrino oscillation phenomenon with conclusive evidence.

In 2007, the Fermilab Miniboone experiment in the United States rejected the results of the LSND experiment.
In 2011, the Italian Large Neutrino ** Experiment (OPERA), the "Neutrino Faster-than-Light Experiment" reported on November 20 that researchers from the Italian Large Neutrino ** Experiment (OPERA) released new experimental data on November 17, local time, reconfirming the results of the "neutrino faster-than-light" experiment in September. However, since the two groups of people belong to the same experimental institution, scientists from all over the world hope that there will be an independent experimental institution that can replicate and analyze them. The repetition of this experiment under multiple conditions in order to be conclusive is of great significance, completely subverting the basis of Eigstein's theory of relativity, and will rewrite many laws of physics, which requires great care.

Recently, some organizations said that the experiment was redone, and it was confirmed, but no official article was published. For such a breakthrough experimental result, it takes many iterations to make a conclusion. The changes it brings are huge, and the bottom of physics will be turned upside down.

Truly. It is likely that the great theories of the 2o century, quantum theory and relativity, are wrong. These two theories are at the same time the theoretical basis of modern physics.
Influence permeates every aspect of modern physics. It is likely to face a crisis of physical theory. At the same time, it may give rise to new theories.

In the 80s, Chinese university teachers had already rejected the hypothesis that the cornerstone of the Einstein and Lorentz transformations, namely that the speed of light is constant, and that the speed of light is extremely fast--- and the speed of photons is the fastest moving object in the world. In other words, modern physics should have been rewritten long ago.
-
It is said that it forgot to consider the relativistic effect and is being redone.
-
According to modern physical theories, experiments and observations, neutrinos do not exceed the speed of light.

The faster-than-light neutrino experiment made a low-level error, and scientists say Einstein's theory of relativity is still correct.
Italy's Opera project, which made global headlines last year for the discovery of neutrinos at faster-than-light events in its experiments, recently admitted that two mistakes may have affected the results of the experiment. Chinese scientists say the experiment made a "low-level mistake" and that the basic principles of relativity remain correct.
The results of the experiment shocked the world.
In September last year, Italy's OPERA neutrino research experiment found that neutrinos appear "faster than light", and neutrinos arrive 60 nanoseconds earlier than the speed of light. If this result is verified, it means that Einstein's special theory of relativity, the foundation of modern physics, will be seriously challenged, and mankind's understanding of time and space will have to start anew.
Since then, a large number of physicists have begun to study this phenomenon. Fermilab announced that it would repeat the experiment, and scientists from other laboratories of the Opera project also conducted independent experiments, but found that neutrinos did not exceed the speed of light.
On the 22nd, the official website of the authoritative scientific journal "Science" disclosed that an anonymous source familiar with the experiment revealed that the reason why neutrinos are faster than the speed of light is because the optical fiber connected to the GPS signal receiver is "poorly contacted".
The Opera project later issued a statement saying that it had identified two issues that could "seriously" affect the results of the experiment. The first problem is that the oscillator that sits between GPS synchronizations and gives neutrinos a manufacturing time tag; The second problem lies in the optical connection that transmits the external GPS signal to the Opera master clock. These two questions can affect the flight time of neutrinos.
Experimental errors are manageable.
Although the statement of the Opera project does not use the word "error", the scientific community has taken it as an official admission of a mistake in the experiment.
Chen Hesheng, director of the Institute of High Energy Physics of the Chinese Academy of Sciences, believes that this is a "low-level error" and is "within a controllable range". Chen Hesheng said that after the results of the Opera experiment came out, although some theorists were given room for imagination, most of the physics community was skeptical. "Scientists should have the ability to judge, even intuition, and analyze every step of the experiment to see if there are any errors.
Now it seems that the basic principles of the theory of relativity are correct. ”
Perhaps, the microwave crest in the waveguide moves faster than the speed of light.
If it is true, of course, the theory of relativity needs to be modified, first of all, the speed of light is the ultimate speed of the universe. However, the fact that neutrinos arrive before photons can only illustrate two problems: (1) neutrinos are faster than the speed of light. >>>More
Question 1: Because A is faster than the light emitted by itself, B has no light and cannot be reflected until A arrives. Only after A arrives, B has light to reflect, but the reflected light must be reversed in time. >>>More
Yes, there are faster-than-light ones.
I can't think of it all at once, so I can say a counterexample. >>>More
Very well conceived. However, the theory is not correct. Approaching the speed of light, the mass increases and time slows down. When the speed of light is reached, static mass matter becomes infinitely heavier, time stands still, and speed does not matter. >>>More
