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.

A picture from the Internet killed Samsung smartphones

The image from the network led to the breakdown of Samsung smartphones. The image was shared by an insider of Ice Universe on his Twitter.

“Never set this picture as wallpaper, especially on Samsung smartphones,” said the blogger, emphasizing that the image from the Internet can break the device. Despite the warning, Ice Universe made a link to the landscape with an image of a flooded island in the setting sun “for enthusiasts.”

Users of Samsung smartphones in the comments confirmed that the mysterious image can really “kill” the device. In particular, after setting the picture as wallpaper, the phone may reboot or turn off, which is fraught with data loss. The comments explained that the cause of the failure could be an incorrect color profile of the file that the system cannot process.

The author later clarified that Samsung was aware of the problem and had already released a special update. The blogger also published a landscape breaking smartphones on the Chinese Weibo service, noting that when loading the social network automatically changes the color profile of the picture.

Samsung device owners who set the image as wallpaper were advised to remove it through safe mode. If the device does not boot in the selected mode, then a clean installation of Android should be performed on the smartphone.

The first ever SpaceX rocket launch with crew will be shown online

May 27, 2020 may go down in the history of astronautics as the day when people first reached the orbit of the Earth on aircraft, fully developed by a private company and owned by it. Previously, without the participation of state organizations, people were only launched into suborbital flights.

The SpaceX-created by Elon Mask, a partially reusable heavy Falcon 9 booster rocket and the Crew Dragon passenger ship, should launch today from the launch site at Cape Canaveral in Florida. The task – to deliver to the International Space Station two NASA astronauts, Doug Hurley and Bob Benken.

Elon Musk tweeted a photograph of the launch site this early morning:

The live broadcast of the launch, which is tentatively scheduled for 16:33 by the east coast of the United States, can be viewed on the official NASA YouTube channel:

As confirmed by CBS News in the press service of the White House, President Donald Trump, despite the ongoing epidemic of COVID-19, decided to personally attend the historic launch and will arrive at Cape Canaveral. Last week, Trump said he was “thinking” about visiting the cosmodrome and added that he would gladly send journalists on a rocket into space to get rid of them for a while. 

True, the start may still be postponed due to bad weather. If the conditions prove to be unfavorable, it will be postponed to the 30th or 31st of May.

The first SpaceX passenger ship, the Crew Dragon, is an evolution of the Dragon transporter, which has recently made several deliveries to the ISS. In total, it can take on board up to 7 crew members, but this time only two will fly, and the rest of the space will be taken by cargo.

The interior of the ship reminds of sci-fi films, and touch screens are used for control, as in electric cars of another company Ilona Mask, Tesla.

The last time the United States National Aeronautics and Space Administration (NASA) launched its astronauts from the United States on an American spacecraft in July 2011. After the crash of the “space shuttle” Columbia in 2003, it was decided to gradually phase out the shuttle program and focus on developing a new ship that would also be suitable for traveling to the moon.

The first manned space flight, organized by a private company, took place back in 2004 – the SpaceShipOne rocket plane with pilot Brian Bonnie on board, reached a height of 100 km above the surface in a suborbital flight and successfully returned to Earth. For comparison, the altitude of the orbit of the ISS, where the Crew Dragon astronauts go, exceeds 400 km.

SpaceShipOne was developed and launched by Mojave Aerospace Ventures, a joint venture between Microsoft co-founder Paul Allen and engineer Burt Rutan of Scaled Composites.

Scientists have created a robotic eye that is completely similar to human

The developers plan to make it completely autonomous due to power from sunlight.

Scientists have created an artificial eye, the device of which almost completely copies the structure of the human organ of vision. Its diameter is about two centimeters, it has a retina made of nanowires and a lens for focusing light instead of the lens. The article describing the development was published by the scientific journal Nature.

We can see due to the fact that the light that enters the eyes passes inside them through the lens system and enters the photoreceptors in the retina. They convert particles of light into signals that are transmitted to the brain. Scientists have long been trying to reconstruct this complex system to create robots or in order to try to restore lost vision to people.

Another and relatively successful attempt to achieve this was made by scientists led by Zhiyong Fang of Hong Kong University of Science and Technology. The artificial eye that they created looks like a ball about two centimeters in diameter, filled with a fluid that conducts electric current. The eye of an adult is about the same size, inside it is also filled with a jelly-like liquid.

The device can see thanks to an artificial retina made of photosensitive nanowires. They are made on the basis of perovskite – a hybrid material, which due to its unique structure is now widely used in solar panels. Nanowires react to light and transmit a signal about it further like the photoreceptors of the human eye.

To test whether this eye can see, scientists projected images of several letters onto it. The device successfully recognized the letters I, E, and Y. However, while it creates an image of rather poor quality – about 100 pixels, compared with 120-140 megapixels of the human eye.

For operation, the device needs an external power source. However, scientists plan to make the artificial eye self-contained so that the device works like a small solar cell.

Among other plans of scientists – to check whether it is possible to subculture these nanowires to the human optical nerve. In addition, the developers hope to increase the quality of the picture to the level of the human eye and even surpass it by an order of magnitude.
