Longest-lived exotic particle discovered that will change modern physics

Analyzing data from the LHCb detector installed at the Large Hadron Collider, scientists have found reliable evidence for the existence of a unique particle - a doubly overtly charmed tetraquark. And no matter how outlandish its name sounds for a person who is not familiar with the Standard Model, it gives physicists even more strange information: it seems that modern scientific ideas about the structure of the world will again have to be pretty shaken up

The shrinking universe will push us into a black hole. But noticing the end of the world won't be easy

New work by Russian researchers indicates that the Universe has not always been expanding - and will contract again in the foreseeable future. Moreover, it is doubtful that humans will be able to survive the cycle of its compression. But the good news is that the universe itself is no longer in danger of heat death. Understanding the details

Michio Kaku is one of those popularizers of science who have been actively working in it for more than a dozen years. In a new interview, timed to coincide with the release of the new book, he told how and why it is necessary to explain complex physical concepts to the broad masses, and also answered many questions "about life, the Universe and in general."

Introduction to the Theory of Everything: simple - about the main goal of modern physics

The more we learned, the more questions we had. And, perhaps, the main one: how to find a general explanation for all phenomena? To answer it, you need to create a Theory of Everything

Freeman Dyson: physicist, heretic, predictor of the future

Freeman Dyson: physicist, heretic, predictor of the future

On February 28, 2020, the physicist Freeman Dyson, whom most of us know from the "Dyson sphere", died - the concept of a huge sphere that fully uses the energy of a star and gives room for life to quintillion people at once. However, in fact, this is not exactly his idea, but Dyson's contribution to other branches of science and technology was much more important. So much so that all Western media trying to write about his death faced a serious problem: a great scientist died, but because of "heretical" views, even in the necro

They found "hair" at black holes, which casts doubt on one of the most important hypotheses based on the theory of relativity

American physicists have simulated black holes with extreme parameters and found them to have unique characteristics. They are also called "hair" because they can distinguish such astronomical objects with the same mass, spin and charge. And this runs counter to one of the direct consequences of General Relativity - the no hair theorem
