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.

Parallel worlds cosmology

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.

Japan has developed an inflatable scooter that weighs practically nothing

The University of Tokyo engineers have developed the Poimo inflatable electric scooter, which is created individually for each owner. It is enough to send your photo to the manufacturers – and a personal optimized model will be assembled for you.

The scooter is designed with a special program for the body size of a particular user and his specific fit. Moreover, each owner is free to make any changes to this model. If he makes any changes to the drawing, the program will automatically redesign the electric bike to maintain its strength, stability and controllability. When the model is finished and approved, it is handed over to the manufacturer.

Scooter Poimo

The scooter consists of seven separate inflatable sections that are constructed from durable fabric and sewn with straight stitch. It remains to add electronic components – in particular, a brushless motor and a lithium-ion battery. 

The finished electric scooter weighs about 9 kg and can travel at speeds up to 6 km / h (that is, slightly faster than a pedestrian). It can work for an hour on one charge.

This is how the current version of Poimo looks like in action:

Excerpts from Elon Musk’s speech at the Martian Society convention

Elon Musk’s comments with questions relayed from the Mars Society Membership by Dr. Robert Zubrin, James L. Burk, and Carie Fay. Following Elon’s 30 min time, Dr. Zubrin took additional questions. This special event was part of the 2020 Mars Society Virtual Convention from October 14-18, 2020.

About Starship Test Schedule:

– entering orbit – with a probability of 80% -90% will take place in 2021

– the probability of the return of the ship and the 1st stage in this flight is 50%

– test of refueling in orbit – 2022

– Starship lunar version – 2022 or 2023

– Starship flight to Mars – around 2024

The goal of the Starship is to build a self-sufficient settlement on Mars as quickly as possible. Musk does not rule out the possibility that this will not be achieved during his lifetime. According to his rough estimates, to create a self-sufficient city, it will be necessary to deliver 1 million tons of cargo, which corresponds to 4-5 million tons in a low Earth orbit. Modern single-use launch vehicles are capable of removing less than 1% of this value.

“Disposable launch vehicles are completely stupid. They are a waste of time. I think people need to stop wasting time on this. If you try to sell a disposable plane, you will be thrown out of the office. If you try to sell a disposable car, you will also be thrown out of the office. “

A series of questions and answers followed:

What is the best landing site on Mars?

– I’m not sure about that. But I can name the criteria. The first of these is latitude: most likely it will be in the northern hemisphere, far enough to the north to have water ice, but to still have enough sunlight.It also needs to be low to get the most benefit from atmospheric braking.

How do you prioritize mission priorities: research, infrastructure construction, and science?

– The first will be the construction of a fuel plant.

A question from a teenager who wants to become an engineer and robot maker with a dream to work at SpaceX: what is the most important education in order to become an engineer?

– There are many varieties of this profession: you can be an aerospace engineer, in the field of electronics, software, or a chemical engineer involved in creating safe production of fuels. I think physics is a good foundation for critical thinking.

Boring Company was originally conceived as a tunnel manufacturing firm on Mars?

– No. It was originally something of a joke. I thought tunnels were a good solution to reduce the traffic problem in cities and improve the quality of life by turning parking lots into green parks. To do this, you need to go to 3d [get away from the “flat” infrastructure – approx. per.]. I think tunnels are good for Mars too. But there you need a lot lighter equipment: you don’t care about mass on Earth, but you will have to take care of it a lot when going to Mars.

At Boring Company, have you learned a lot of technology that might come in handy on Mars?

– I think, yes.

Do you have any tips for young people who love Mars but don’t know how to participate in its settlement?

– I think any strong advocate of the need to conquer Mars matters. People often don’t even think about it. I often talk to people who don’t even know about it. Therefore, I consider it important for humanity and consciousness in general to bring a discussion about this to society. Talking about it with friends and acquaintances – I think this is what we should do. In my estimate, we will spend less than 1% of our efforts on Mars exploration, exactly less than healthcare, perhaps even less than cosmetics – this will be enough to make life multi-planetary. But this requires people to start talking about it 100 times more often. I think this is what really matters. [the entire cosmonautics of the world is $ 424 billion a year, while cosmetics is $ 532 billion, and tobacco production is $ 849 billion – approx. per.]

What’s the coolest part about Starship development?

– I think the coolest detail is the ability to work with a great group of engineers and come up with interesting solutions. I think the best thing is the opportunity to work with smart and creative people who come up with solutions that were not available before. This is a great reward.

What do you focus on when hiring, especially with regard to engineers?

“We’re looking for signs of exceptional ability. Or at the very least, striving to do exceptional things at SpaceX.

Are you planning to make a Mars-Earth communication system like Starlink?

– Yes, I think we will use a laser, probably launched into orbit, to avoid atmospheric diffraction. Thus, it will be a laser beam going from the orbit of the Earth to the orbit of Mars. And also relay satellites in solar orbit, since the laser beam cannot be sent through the Sun [when it is between Mars and Earth – approx. per.].

Can Starship be used for other destinations like Venus and other planets?

– Starship will be able to travel to any target in the solar system that has a solid surface when fuel depots appear. It is not the kind of transport that will take us to other stars, but when we become a multi-planetary species, we will create a demand for innovation in space travel that will ultimately lead us to interstellar travel.

Cern Scientists Plan an Impressive Experiment – They Will Come Into A Parallel Universe

Cern scientists are once again preparing to impress the entire planet and become the focus of discussions with the new experiment they are planning.

An experiment that, if it brings the fascinating result that scientists have in mind,  will change the way we think about the world , will take place in the next few days at the Large Hadron Collider, the European nuclear center, Geneva CERN Research.

The astonishingly LHC complex, the largest, most energetic elemental accelerator in the world,  will be “fired” for the first time to its highest energy levels, in an effort to detect – or even create – tiny black holes. 

If it succeeds, then, a completely new universe will be revealed – rewriting not only the books of physics, but also the books of philosophy! 

It is possible, however,  that gravity from our universe will “leak” into this parallel universe, as LHC scientists say. 

From the Higgs boson to dark matter and the parallel universe

According to the British Express, the experiment is sure to “trigger” the critics, who are worried about the LHC, many of whom warn that the elementary particle accelerator will mark the end of our universe, creating a of the black hole.

Nevertheless,  Geneva has remained … intact since 2008, when the LHC began its spectacular “work”.

The first scientists at the Large Hadron Collider proved the existence of the Higgs boson – a key building block of the universe – and the LHC appears to be on track to locate “dark matter” – a previously undetectable force now considered that it constitutes the majority of matter in the universe, being, in fact, the reason why the latter is constantly expanding and moving away. 

So next week’s experiment is considered to change the game. 

The truth is out there

Mir Faizal, one of three heads of the three natural groups behind the experiment, said: 

“Like many parallel sheets, which are two-dimensional objects (width and length) can exist in a third dimension (height) , so parallel universes can also exist in higher dimensions. We anticipate that gravity can leak into extra dimensions, and if that happens, then tiny black holes can be produced in the LHC. 

Normally, when people think of the multiverse, they think of the interpretation of quantum mechanics by many worlds, where every possibility is realized. This cannot be tested and so it is a philosophy and not a science. We do not mean this with parallel universes. What we mean is real universes, in extra dimensions. The truth is out there.”
