12. FINDING THE VALUE OF VACUUM GRAVITATIONAL REPLAYAccording to modern quantum physics, vacuum represents the lowest energy state of all fields. In a vacuum, even without real particles, virtual particle processes take place. But the question of the density of the vacuum, the energy of the vacuum is complicated, it is excluded from the formulas everywhere
11. DENSITY - TIME CLASSIFICATION OF ELEMENTARY PARTICLES OF DYNAMIC TIME PHYSICSIn this sublunary world, everything depends and is directed by time. Time is the most important function of this world, of man, physics, chemistry, biology and the Universe, that is, the function of time must be explicit and implicit in all formulas

While Europe is trying to stop cloning, Chinese scientists are making another breakthrough. Who is the future for? Perhaps in 30 years our world will be inhabited by clones of people and animals. 1
To date, the shepherd dogs Tom and Jack are the only clones in Russia, both among dogs and living creatures in general. Unusual dogs entered service in the canine division of the Federal Penitentiary Service of Russia in the Republic of Sakha (Yakutia)
Recently, cloning from the realm of science fiction has moved into the category of those branches of science that seem mundane to us. For example, recently we wrote that a group of scientists from China managed to clone several pigs at once
China intends to create the world's largest animal cloning center. It will be located in the Tianjin area of northeastern China based on the local zone of technical and economic development. The project cost is 31.3 million dollars
Valery Spiridonov, the first candidate for a body transplant, talks about how modern technologies for cloning living organisms were born, and discusses the consequences of their appearance for humanity
A little more - and human cloning will become an everyday reality. But for some reason this frontier taken by science does not cause delight among people
The female of the Pyrenean tur, resurrected by DNA transplantation, died after 7 minutes of life
In the photo: Stuffed Dolly at the Royal Edinburgh Museum In 1996 at the Rosslyn Institute near Edinburgh (Scotland) for the first time in history a mammal was cloned from an adult cell
New technologies will appear in the near future.Mass cloning of human cells will begin in Russia in the next 10 years. Alexey Deikin, Deputy Head of the Shared Use Center of the Institute of Gene Biology of the Russian Academy of Sciences, spoke about this in an interview with News
Nature has long known the principle of cloning, so identical twins appear identical to each other. However, a couple of years ago, the first primate, one of the closest species to humans, was cloned in China. This event gave rise to discussions about whether a person can be cloned
In a special exclusive interview with the Guardian, leading European scientists reveal their revolutionary plan to grow Neanderthal brains in the laboratory
For the first time, scientists made eggs from a human blood cell. This is the first step towards the possibility of mass production of human eggs using body tissue or blood of other people
People have long dreamed of cloning. Many writers, screenwriters and artists have touched upon the topic of clones more than once in their works. Is it realistic in our time to "copy" a person and if so, what will come of it?
A group of researchers from China and Austria teleported three-level quantum states, also known as kutrits. The research results are published in the journal Physical Review Letters.For the first time, scientists have successfully conducted such an experiment
When Barbra Streisand told Variety magazine that she had cloned her dog for $ 50,000, many first learned that copying pets and other animals - it's real
The thought experiment of "quantum suicide" was first staged by Max Tegmark in 1997, and it looks like this: imagine that a gun is connected to a machine that responds to the rotation of a quantum particle every time you pull the trigger. If the particle rotates clockwise, the pistol will fire; if it rotates counterclockwise, it will not
New experiment in the field of quantum physics was a step towards realizing a strange idea, previously limited to theoretical measurement
Scientists from Germany used light and atom to obtain the state of "Schrödinger's cat" - and achieved the state of superposition many times. One of the world's most famous thought experiments reimagined
What is cloning? Cloning - these are methods of obtaining several identical organisms by asexual (including vegetative) reproduction
