There are parallel worlds with other versions of us, physicists claim

Somewhere nearby there are other parallel worlds with different versions of ourselves, with different stories and alternative results of what we experienced. The theory of parallel worlds is not just an invention, but one of the most exciting possibilities presented by theoretical physics.

According to physicist Leah Broussard, who led the research project on the study of hidden worlds, a new theory has appeared called the “interaction of many parallel worlds.” The theory assumes not only the existence of parallel worlds, but also that they interact with our world at a quantum level and, therefore, can be detected.

In theory, parallel worlds is a continuation of the hypothesis of many worlds in quantum mechanics. The idea of ​​a multiverse universe postulates that all possible alternative stories and even the future are real. Moreover, each of the worlds represents the real world, although parallel. Amazing and even confusing, isn’t it?

Sean Carroll, a theoretical physicist at the California Institute of Technology, actively supports the theory of parallel worlds. This became the theme of his new book, Something Deeply Hidden. “It is possible that there are several worlds in which you made different decisions,” Carroll said in an interview with NBC News.

“We just obey the laws of physics. How many versions can you have? “We do not know whether the number of worlds is finite or infinite, but this is certainly a very large number.”

Theoretical physicist Carroll knows that theory of parallel worlds sounds like something from a science fiction movie. But he is convinced by the idea that he is just one of the many Shawn Carrolls working in alternative versions of reality.

The concept of a single person going from birth to death has always been just a simple approximation of reality. For the physicist, the interpretation of many worlds extends this idea: “The world doubles, and everything in the world is consistent with this.”

The interpretation of many worlds raises all kinds of questions about the multiple versions of reality and the multiple versions of us that exist in these worlds. Carroll has several answers to questions about these mysterious worlds.

If new universes constantly appear, isn’t something created out of nothing, violating one of the most basic principles of physics? According to the scientist, this is not so, since it only seems that you are creating additional copies of the universe.

“Why are we experiencing a specific reality, but not one of the others?” Carroll explains. “Where else would you be? It’s like asking why you live now and not another time. Everyone in every world thinks they are singular. ”

Visit parallel worlds.

Carroll also has a disappointing answer to one of the most compelling questions of all: could you cross and visit one of the other realities and compare yourself with an alternate version of yourself?

“As soon as other worlds appear, they go their own way,” Carroll says. “They do not interact and do not affect each other in any way. An intersection is like traveling at the speed of light, but this is not something you can do.

The critique of Carroll’s interpretation of many worlds is that, although it offers a different view of the reality in which we live, for some scientists it does not offer new ideas about how nature works.

“There’s no content in it,” says physicist Christopher Fuchs of the University of Massachusetts. Fuchs offers an alternative theory called the quantum Bayesian approach. This is the way back to unique old-fashioned reality.

He claims that the universe changes when you look at it, not because you create new worlds, but simply because observation requires interaction with your environment. There are no assignments in this theory, no other lives for us.

“Thus, the measurement is degraded by be something mystical, to be something as mundane as crossing a busy street: this is an action that I can take that obviously has consequences for me, ”Fuchs explains.

But Carroll is not subject to this criticism and alternative explanations. He considers them too complex and unsupported by data. True, for other physicists the ideas of “one-dimensionality” are simpler and more familiar, although they are boring and do not offer the ideas of a “divine idea.”

At the same time, the concept of multiple realities can be confusing. However, for a modern person who is accustomed to the concept of “3D reality”, the basic concept of many worlds is “clear, clear, beautiful, simple and clean.”

Everything seems to indicate that our own actions will directly affect our different “I” in parallel realities. Then the decisions made by our “I” will also affect us in other worlds. However, what will your life be like if you make different decisions? Perhaps one day you will be able to see one of these alternative worlds and find out all the answers.

Scientists create a virus “capable” of destroying any kind of cancer

An Australian company called Imugene has created a virus that can eliminate all types of cancer. So far it has been tested on Petrie plates and mice, where it worked by reducing tumors and killing diseased cells. Human tests should start soon.

Although it seems strange that a virus is used to treat a disease, this is possible and scientists have been doing it for years. A modified herpes virus has been implemented to treat some types of skin cancer.

Now, scientists are using cowpox virus as the basis for their cancer treatment, called CF33. The first tests on mice have reduced tumor cells, so Imugene believes that the next logical step is to perform experiments on humans, in order to verify the effectiveness of the treatment.

During the next tests, which will take place next year in Australia and other countries, the treatment will be implemented in some types of specific cancers, such as triple negative breast cancer, melanoma, lung cancer, bladder cancer, gastric cancer and intestinal.

Professor Yuman Fong, a cancer treatment specialist, told the Daily Telegraph that there is evidence that some viruses could fight cancer since the early 1900s when people were vaccinated against rabies and their cancer disappeared. entered the reference phase.

However, it was feared that just as the virus was toxic to cancer, it was also to humans, but now things are different and could be the best way to attack cancerous tumors.

In Imugene experiments, patients will observe that the virus will be injected directly into their tumors, where it will multiply to the point of destroying it. The immune system itself should therefore be alerted to other cancer cells in the body, attacking and eliminating them.

This is very promising, but it will take years before the health strategy is used in hospitals, because it remains to be seen how the immune system reacts to the virus itself. Furthermore, cancer cells mutate to survive, and this is how they have become resistant to treatments such as chemotherapy and immunotherapy.

The CDC Says It Really Knows What’s Causing “Vape Lung” This Time

Finally, the government says it’s pretty sure what’s behind the mysterious “vape lung” epidemic that’s been spreading across the country, affecting more than 2,000 people and killing at least 39.

A compound called vitamin E acetate has been found in all 29 lung fluid samples taken by the U.S. Centers for Disease Control and Prevention (CDC), The Washington Post reports. And while the CDC was looking for a wide range of other toxins and dangerous compounds, it didn’t find any in those particular samples.

The FDA first identified vitamin E acetate as a possible cause for vape lung back in September. The compound, which WaPo reports is used as a cutting agent in black market THC vapes, is considered safe to eat and touch. But scientists have a poor understanding of what vaporized vitamin E acetate does when inhaled.

The CDC research strengthens the vitamin E acetate hypothesis because the 29 lung fluid samples came from people in 10 U.S. states, helping to rule out other, more local causes for infections. Still, it doesn’t serve as a definitive explanation for vape lung.

“While this is a big step in helping us understand what may be causing these injuries, these findings do not rule out the potential for other compounds or ingredients as contributing factors,” public health expert Scott Becker, executive director of the Association of Public Health Laboratories, told WaPo. “There may be more than one cause of the outbreak.”

Still, CDC principal deputy director Anne Schuchat told WaPo that the research paints vitamin E acetate as “a very strong culprit of concern” for vape lung. Even if other factors are at play, that knowledge could help prevent the outbreak from spreading even farther.

Blue light causes aging

The prolonged exposure to blue light coming from our phones, computers, and many other household appliances can negatively affect a person’s life expectancy. Scientists suggest that the blue waves that LEDs emit damage the cells of the brain and retina, even if there is no direct incidence of light rays. Scientists conducted a series of studies on an ordinary fruit fly, as a result of which it turned out that light waves emitted during the burning of LEDs accelerate the aging process.

According to previous research, blue light is 15 times more dangerous to the retina than the remaining spectrum

Is blue light harmful?

Light is electromagnetic radiation, each color of which has its own specific amount of energy. At the beginning of the light spectrum there is red, which has low energy and is easily perceived by the human eye, closer to the top of the spectrum is blue light, which has the highest energy and is able to penetrate the retina, quickly wearying our organs of vision.

Artificial blue light, which comes from modern gadgets and devices, occupies the most “harmful” part of the spectrum, the wavelength of which is between 380 and 500 nm. Light waves of this range are the shortest of visible radiation, while scattering most actively.

Scientists have long confirmed the negative effects of blue light on humans, but still continue to conduct more detailed studies on its effects on the human body and still do not plan to dwell on the information received. So, scientists from a university in Oregon published the results of new studies in the journal Aging and mechanisms of disease.

During the experiment, researchers used  an ordinary fruit fly – Drosophila melanogaster, whose body, due to its cellular mechanisms of development, is similar to other animals and people.

The flies underwent daily 12-hour light cycles.

During the study, researchers used 3 groups of flies. The first group underwent daily 12-hour cycles: 12 hours in the light and 12 hours in the dark. The second group was always in the dark and was used as a control, and the third group was subjected to filtered blue light. According to the results of the study, it was found that the flies from the first group had a shorter life span. A study of flies that were exposed to 12 hours of blue light confirmed damage to retinal cells and even brain neurons, reducing the ability of flies to climb fences.

In the experiment, mutants of fruit flies were also used, some of which did not have developed organs of vision, but even brainless flies showed brain damage and impaired coordination. Thus, flies did not have to see the light in order for it to cause disturbances in the body. Researchers also noted an interesting fact that flies try to avoid blue light if given a choice.

Scientists are interested in creating and developing a new and healthier spectrum of light in order to increase the life expectancy of users of modern electronics

Scientists note that the presence of natural light is crucial for the circadian rhythm of the body – a cycle in which a number of physiological processes occur, such as brain activity, hormone secretion, cell regeneration, etc. However, the increased exposure to artificial light, which is increasing in the modern world, is one of the risk factors for sleep failure and many other circadian disorders.

The use of LED lighting, various gadgets and devices exposes people to more and more light in the blue spectrum. But due to the fact that these technologies are quite new, it is not possible to find out about their impact on a person throughout his life.
