What Happens To Our Brain When We Experience Complete Silence & Peace of Mind

Silence. How often do you truly get to experience this? Nowadays, silence is a very rare commodity indeed as we are constantly bombarded with noises from people, traffic, airplanes, music, advertisements, construction and the list goes on. I’ve been thinking a lot about silence and how much I would like some as I’ve been travelling and am constantly subjected to honking cars, screaming tourists, and clanking sounds all around me. Silence, is actually not something that is very easily obtainable -silence is golden. So how important is silence and is it a detriment to the well-being of our minds if we don’t have it?

In 2011, the Finnish Tourist Board ran a campaign that actually used silence as a marketing product. Their campaign aimed to entice people to visit Finland to experience the beauty of the silent land. The campaign released a series of photos of single figures in nature along with the headline, “Silence, Please.” Another tagline was added by Simon Ahnolt, an international country branding consultant that said, “No talking, but action.”

Finland is onto something here. In their campaign we are seeing the beginning of using silence as a marketing technique as it is something that is becoming more and more attractive as it is becoming more and more rare. Really, think about it, how often are you in complete silence? Noise pollution is something we deal with every single day and often, we don’t think twice about it. Scientific studies are now showing that silence is much more important for our brains than you might think.

Science For Silence

A study published in 2013 in the journal, Brain, Structure and Function, used various types of noise and silence and monitored the effect the sound and silence had on the brains of mice. The silence was intended to be the control in the study, but what they found was surprising. The scientists discovered that when the mice were exposed to two hours of complete silence per day they actually developed new brain cells in the hippocampus, which is the region of the brain that is associated with memory, emotion and learning new things.

The growth of new brain cells doesn’t always mean improved health benefits, but in this instance one of the researchers, Imke Kirste, says that these new cells appeared to become functioning neurons.

“We saw that silence is really helping the new generated cells to differentiate into neurons and integrate into the system.”

So, basically this means that silence can actually grow your brain.

Another study from 2001 defined a “default mode” of brain function that showed that even when the brain was perceivably resting, it was still perpetually active and internalizing and evaluating information. Follow up research found that this default mode is also used in the process of self-reflection. In 2013, in Frontiers in Human Neuroscience, Joseph Moran et al. wrote that the brain’s default mode network “is observed most closely during the psychological task of reflecting on one’s personalities and characteristics (self-reflection), rather than during self-recognition, thinking of the self-concept, or thinking about self-esteem, for example.”

When the brain is in a resting state it is able to integrate internal and external information into “a conscious work space,” according to Moran and colleagues.

In other words, when the mind is not distracted by noise or goal oriented tasks there lies a quiet space that allows your conscious work space to process things in a different manner. In these periods of silence your brain has the freedom that it needs to realize it’s place in your internal as well as external world.

As Herman Melville once wrote,

“All profound things and emotions of things are preceded and attended by silence.”

Silence Has The Opposite Effect On The Brain As Noise

Noise, at pretty much any levels cause stress and tension to the body, silence releases tension in the brain and body. A study published in the journal, Heart – discovered that just two minutes of silence can prove to be even more relaxing than listening to “relaxing” music, go figure.

The effect of noise pollution on our ability to perform a cognitive task has been studied extensively. Noise can interfere with task performance at work and school and can also be the cause for a decrease in motivation and an increase in the making of errors. Cognitive functions that are most commonly affected by noise are reading attention, memory and problem solving. You may be able to relate to this if you’ve ever tried to read or study and another person is blaring music or watching T.V. close to you, it’s almost impossible to concentrate.

Interestingly, a number of studies have also shown that children that live in houses or go to schools which are near airports or under airplane flight paths, railways, or highways have lower reading scores and are slower in their cognitive and language skills.

Luckily, This Can Be Resolved

The human body is a truly remarkable thing, and the brain – well, this is beyond comprehension. In other words, it is beyond the brain to fully understand the brain, how about that? It is possible for the brain to restore its finite cognitive resources and according to the attention restoration theory, when you are in an environment with lower levels of sensory input the brain can actually recover some of it’s cognitive abilities. When exposed to silence the brain can let down it’s heightened sensory guard and restore some of what has been lost through exposure to excess noise.

If traveling to Finland is out of your reach, don’t worry, there are many other ways to find silence. If you live in a city it might be more of a mission, but it is always possible. The sounds of nature don’t really count as noise pollution, so if you can go for a walk through a forest, or a quiet park or sit by the beach, maybe even try out a sensory deprivation tank – you can experience the benefits that come from experiencing silence. We all need it, but it’s so easy to forget about it in our buys, go, go, go type of world we’ve created. Luckily from awareness comes change, and we can choose to make time to do what’s best for our mind, body and soul.

Much Love

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.”
