The sun shield that some scientists want to build

Faced with the imminent threat of solar flares that could seriously affect life on Earth, a group of scientists has proposed a novel form of protection: a gigantic sun shield ..

With a sun shield we could protect the Earth from the king star, according to scientists

Human activity in the 21st century increasingly depends on the infrastructure located in the orbit Low Terrestrial (LEO), that is, the many telecommunications satellites currently in space, the International Space Station and the GPS satellite fleet.

For this reason, the solar flares have begun to be considered a serious danger to human life, because if this infrastructure is destroyed we would be left without the tools that make our comfortable existence on the planet possible.

To treat this threat a team of scientists from Harv University ard recently published a study that proposes a bold solution: put a giant magnetic shield in orbit.

The study, which was the work of Manasavi Lingam and Abraham Loeb of the Smithsonian Center As a Harvard Astrophysicist in the United States, it is titled "Impact Strategy and Mitigation of the Solar Leakage of the Future".

As they explain, solar flares represent a serious risk in the world today, and they will become an even greater threat due to the growing presence of humanity in the lower orbit.

A solar flare in full action

In fact, if a solar storm like the Carrington event of 1859 occurred today, it would cause global damage to electric power networks , satellite communications and global supply chains.

To address this, Lingham and Loeb developed a simple mathematical model to assess the economic losses caused by solar flare activity over time.This model considered the increased risk of damage to the technological infrastructure based on two factors.

First, they considered the fact that the energy of solar flares increases over time, then joined the exponential growth of the technology.They determined that over time, Powerful solar flares will be more likely.

Loeb explained that there will be an event that will cause damage within the next 150 years comparable to the current US GDP of 20 billion dollars, and the damage will increase exponentially in later times until the technological development becomes saturated.

Therefore, Lingham and Loeb considered the possibility of placing a magnetic shield between the Earth and the Sun.

This escu C would be placed at point 1 of Lagrange (Point L1) between the Earth and the Sun, where it would be able to deflect the charged particles and create an arc of artificial shock around the Earth, which would protect it in a manner similar to what its magnetic field already exerts, but with a greater effect.

Lingham and Loeb claim that such a shield is technically feasible in terms of its basic physical parameters Thus, they presented a rudimentary schedule for the construction of this shield and some approximate cost assessments.

Loeb indicated that such a shield could be built before this century is over , and it would be a small fraction of the cost of what would be incurred from the damage of the solar flare.

What do you think of the idea of a sun shield? Do you think they could get it ready in time?

Better to study shortly or long before for an exam? You'll be surprised!

Is it better to study months before an exam or in the previous days? A study reveals the best method! Better to study shortly or long before for an exam? You will be surprised! Are you one of those who study the day before the exam even though they have always advised you otherwise? Now, science says that you might be right to do so because studying when stressed or under pressure favors learning . This is what scientists at the University of Bristol have said, discover that the hormones that are produced when stressed are causing changes in the cells, allowing memories to be stored more effectively in the hippocampus, the part of the brain related to memory. According to the Professor Hans Reul, who directs the research, stress hormones, such as cortisol and adrenaline, change genes within neurons and increase their learning capacity . This The phenomenon is called "epigenetic modification", an alteration of the genome of cells to reprogram DNA in the brain and ...

Are you codependent in love? These signals could indicate that yes

Codependence is a psychological condition that makes you forget about yourself and your emotions to focus on the needs of another person almost completely.The codependent knows no limits and is capable of Forgive everything, just for staying close to who motivates this state.Does it sound familiar to you? We tell you these signs that could indicate a possible codependence. Signals that you are codependent You give more than you receive When we talk about couples, we build the concept of two people who voluntarily decide to work in tandem to keep love afloat .Both ensure that each one feels in harmony with the connection they have built.The romantic companions will do their part to continue strengthening the emotional bond between the two, attending to the emotional needs alike. Instead a codependent person will settle for a unilateral relationship, in which only one person is willing to do whatever it takes, to give whatever he can to neglect himself, so that he can r...

EXISTS! The plant that leads to suicide

We have an ambivalent relationship with nature, which goes from the vision of plants and animals with which we can maintain a harmonious relationship, and that we also need to guarantee a balanced existence, and on the other hand the threatening jungle, full of bugs and willing to push back civilization and cover it if neglected. The truth is in an intermediate place between these two poles, and just as there are dangerous animals for humans, there is also flora that can be harmful and even, as a curiosity, a plant that leads to suicide. The plant that leads to suicide In 1963 Ernie Ryder , an officer of the Service of Parks of Queensland, he was walking in an area of this tropical region of northeastern Australia, when he brushed with his face the leaf of a plant covered with a fluff and known locally as gympie gympie ; what followed next was surprisingly painful: “For two or three days the pain was almost unbearable, I could not sleep or work, and continued to be quite ...

And you, also "procrastins"?

And you? Procrastines too? If you don't, we are sure that you know someone who does it continuously and that, surely, makes you despair.But what does this disturbing word really mean? Let's give an example: you have been dating a person for a long time, you make plans for the future, you have many illusions and projects, however, your partner never seems to decide.He is unable to formalize your relationship because something like that, not only overwhelms him, but even He is lazy. "Are we not well like that?" I often reproach you. Let's give another example: you may have the classic friend who never seems to finish his studies.It is easy to be an "eternal" university student who faces the responsibilities and anxieties of the working world. And what about people who spend all their time in front of a computer screen letting out "real life" ? Sometimes, it is much easier to let ourselves go, evading responsibilities, than to put means t...

How long is love?

How long does love last? The eternal question of those who are in love.Does love last for a lifetime? Does it last 2, 4, 7 years? How long does love last for us? According to anthropologist Helen Fisher love comes to last for some 4 years .Just that first period of infatuation in which the sexual attraction is very important and in which at the end, touching the 4 years, there is offspring., then, in the second phase which is the carino , in which together we raise and educate, and in which that initial sensation fades away.Finally, comes the desire for separation.And, According to this anthropologist, this process is natural, since our organism cannot bear for a long time the ferris wheel of sensations that we feel, due to the chemistry that is generated when we fall in love : the high levels of dopamine, testosterone and norepinephrine that our brain secretes.That is why they have an expiration date: between 1 and 4 years! Researchers at the University of Pisa al...

What is acid rain?

Many times we have heard the term " acid rain " and generally relate it to the weather and possible contamination, but do you really know what it is? In Science Daily Online we explain it below. What is acid rain? The so-called acid rain is a atmospheric phenomenon that originates when acidic compounds are incorporated into the small droplets of water that make up the clouds.It is one of the main consequences related to air pollution that we all breathe the days. This is a cycle that starts at the moment that industries, factory smoke or car engines emit sulfur oxides in the gaseous state that is transported through the winds to hundreds of kilometers.By burning different kinds of fuels considerable amounts of chemicals are released, which not only contain visible particles of gray color, but also have a wide variety of gases not visible, but very harmful for the environment . Acidity values In the troposphere , one of the layers that make up the at...

What do you know about tardigrades? The creatures that would survive in space

If you've been lucky enough to see the sequel to Carl Sagan's famous documentary series, Cosmos , you may have seen an excellent animation of the tardigrades, these microscopic beings also known as “bears of water.” What do you know about tardigrades? Creatures that would survive in space The tardigrados were discovered in the 18th century, and their name literally means "slow-moving." The first to describe them was the German Johann August Ephraim Goezee , in 1773; He was also the first to baptize them as “water bears.” Adults measure 0.5 mm, so they can be observed with the naked eye and find several in a drop of water (young people measure 0.05 mm); there are more than 1,000 species and they are classified as parartropods , that is, similar to arthropods, although there is nothing further from the figure of a crab, or a lobster. Its appearance is that of a being from another world, and it could be, for one of its most extraordinary characteristics and whi...
