Good Lifestyle

Scientists and astronomers spend all day, every day, wearing data looking for answers to the questions of myriads of the universe, but they will be the first to admit that the space is really, really difficult, if not impossible , at least for our mortal spirits - to understand.

So, since even the experts do not know exactly what is happening in the big beyond, it is only natural to know that the United States of Earth-Falling would have hot issues. In this case, you will find the most appointed confusion. So, bucket and get ready for cognitive blastoff on three ... .two ... one! And if you are really interested in directing you to infinity and beyond, prepare it by learning the27 insane things astronauts must do.

For those who slept through astronomy, here is a refresher: our sun, aStaris surrounded by nine-ish (more than that later)planets. These star-planet clusters are calledSolar systems. The clusters of solar systems are calledgalaxies. The Milky Way - it is the galaxy that we are roughly believed about 200 billion solar systems. The researchers set the observable universe - that's what we can tangibly see about 150 billion galaxies. Honestly, however, it could continue, and again and again, and well, you have the point.

In fact, a team of researchers in Oxford recently deployed a model suggesting that the universe is at least 250 times larger thanthis. To put the resulting figure in context, it's more zero zeros that we can not get away from crushing your web browser. And it's just galaxies. Think about how this number applies to solar systems, not to mention planet, suffices to melt the brain of anyone. And for more cerebral science, read on the20 types of artificial intelligence that you use every day and you do not know it.

Yes, these amazing figures indicate that we should have stumbled through extraterrestrial life. Even if you take the most hesitant and hesitant estimates - who come graceful of the recent national research research procedure on the National Academy of Science - about 1% of all the planets of the universe are at all less able to promote sustainable biological life. People toWait but whyput it like that: For each grain of sand on each beach on the planet, there is100 of these planets; In the milk alone, there should be 100,000 intelligent civilizations. So again, where is everyone?

Enter: The Fermi paradox. Indicated by Physicist Enrico Fermi In the 1950s, the Fermi paradox organizes a valiant effort to meet this puzzled enigma. To date, no one has been able to solve it, but the astrological community is divided largely from two categories: that we are the only existing intelligent life, or that there is a very good reason why we n have not yet discovered our cohabiting celestial. For example, maybe we are in a zoo and extraterrestrial life observes us as if we would be a caged panda. Or maybe we are simply in a "rural" part of the galaxy and have not yet been discovered, as the way the 15 centuries explorers had no idea of ​​the American antite tribus existed before Going in the Atlantic. Crazy, right?

Pluto is technically not a planet. But that does not mean that our solar system is limited to eight planets. Scientists believe that there may be a ninth non-discovered planet on the fringes of our space. If you pay attention to the orbital trajectories of celestial bodies, like Uranus and Neptune, you will notice peculiarities.

The reason is likely that there is a huge gravitational body, like a planet shooting things outside Whack.According toKonstantin Ballyboys, Assistant Professor of Planetary Science at the California Institute of Technology, the reason we may not have found "Planet 9" but it's "because it's scandalously dim ... With the best telescopes around, we could simply detect it, we think. "And for more scientific stories of cerebral torsion,That's what life could look like 200 years from now.

The formations in the form of black holes-galaxy where the gravity levels are so powerful everything, including light, are sucked in deeply mysterious remains. The researchers feel that there can be up to 100 million black holes than the milky road alone. But we do not know how they are trained, what they do and, crucially, what happens if the material passes through one.

Among the things that scientists stripping on black holes are when they were trained in the first place. Search for astronomers examining radio frequency images that provide data on early galaxies suggest that black holes may have obtained a quick start. "Significant involvement is that the black holes formed first, then somehow they formed a stellar galaxy around them"Sit Chris CarilliFrom the National Observatory of Astronomy Radio in Socorro, New Mexico, one of the researchers of the report.

We do not really know what this kind of thing is, but scientists believe thatblack matter Can account for about 25% of the total universe - a substance that functions like a spider band, holding together planets, stars and galaxies. There is a lot of evidence that it exists, but it's a mystery what exactly it is. Maybe it's a compound of an undiscovery particle? Maybe it's a previously unknown severity property? Nobody is sure.

One of the biggest questions about dark matter remains around its temperature - it is hot or not. Theories range from hot, hot or cold, with one of the most widely accepted theories - theLambda Cold Dark Itatiation Model-now it's, as his nomenclature suggests, cold and dark. But the jury is stilla lot outside.

In the 1990s, when a group of astrophysicians found that the expansion of the universe was accelerated due to a kind of substance against gravity, they nicknamed this substance "black energy. "Believed to represent nearly 70% or more of the known universe, the theories differ from what exactly a changing energy field called" quintessence "? A property of space neglected by Albert Einstein? It's a Large numbers of something. We just do not know what.

These are allegedly, 80% of star systems are binary systems. They haveof them Suns. Ours is not - at least nor. Astronomers suggested that once we perhaps have had a second sun, which has beenNémesis Dubbed. Followingrecent research, Looking at a cluster of young stars of the Milky Way, finds support for that; Apparently, almost all the stars of sunshine are born in pairs. But unless and until we observed a star whose composition is identical to ours, Nemesis always remained a mystery. And for tips to stay safe from the unique sun, we still have, check the20 ways that the sun hurts your health.

A popular theory is that it follows from adummy From a "protoplanet" striking the earth about 4.5 billion years and knocking a piece of debris. But other theories - like the relatively hidden, one of them being a blocked asteroid in our sweater pull-pull-persist. In any case, no one knows it.

Of all the planets of our solar system, mercury can be the most mysterious. It's so close to the sun that terrestrial telescopes may have trouble looking at him, andWhat we were able to gather About this left scientists scratching their heads.

A large metal core represents about half of the volume of the planet (the earth is only 10%, compared to). Some theorized, it was a planet similar to the characteristics of the earth and the Venus, but the collision in the remains of his crust or that the sun closed his crust. Anyway, when it comes to this planet, there are many unanswered questions.

Themost powerful broadcast Never sent into the space was scratched in the sky in 1974 - targeting the M13 globular star cluster. The message (which consists of a graph showing a human, our solar system and a DNA strain, among others) should not reach its destination for about 25,000 years. But who knows: someone else could have been looking for me in time.

This is when two particlesmirror Or interact in a certain way, even if they are separated by enormous distances, even at completely different corners of the universe. Einstein called "Fantasy Action at a distance" and for this entanglement to occur seems to require some sort of signals traveling between the particles - at a speed faster than the speed of light. It would be a trick quite difficult to shoot, but scientists have not yet found a fully satisfactory explanation for the phenomenon.

It's like a regular case,but the opposite. More specifically, an antimatter particle has the same mass as a particle of material, but with the opposite electric charge, it therefore destroys the normal material at the moment when it connects. Although this would have been created next to the subject after the Big Bang - and still remains in the world today, scientists do not know exactly why. They just know that we should stay away from it.

It turns out that in space, you can hearSomething shout, or at least "roar". The researchers have detected a cacophony of radio signals likely to make it difficult to send other signals by space (although it is impossible to hear with the human ear). Dale Fixsen, a research scientist from the University of Maryland,RecountMental floss That there are several theories for what causes this, the possibility that the roar "of the first stars" at "Galaxies Radio", but they are, after all, theories.

When stars lack fuel, they come out with a bang, exploding in a massive explosion called Supernova. But during research and technology such as NASANuclear Specoscopic Telescope Table Have so illuminated on the process, there is still something of a mystery.

"The stars are balls of spherical gases, and you might think that when they finish their lives and explod that the explosion would look like a uniform bullet extending with great power," said Fiona Harrison, the investigator Nustar in Caltech, on the announcement of the conclusions in 2014. "Our new results show how the heart or engine of the explosion is distorted, possibly because the interior regions slosch literally before returning."

The high energy particles of the deep space called "cosmic rays" have struck the earth and expand,According to the conclusions of the spatial vessel of advanced composition of NASA. "In 2009, cosmic ray intensities increased by 19% beyond everything we've seen over the last 50 years," said Caltech Richard Mewaldt. "The increase is meaningful, and this could mean that we need to rethink the amount of astronaut shielding radiation with them on deep missions." But what they do not know is exactly what causes this rise or exactly what are the dangers it could ask.

Any fan ofA strange doctorCan appreciate this, as small as we could feel in this universe, it may only be one of the potentially billions of universes. But while there are a number of legitimate reasons, like the theory of chaos, or the butterfly effect, or called "daughter universe" - align behind this ideation, there is, for the moment, none way to conclusively prove it in one way or another.

A version of the multived theory, this idea develops quantum mechanics, which describes the world in terms of probabilities and suggests that all possible results occur, each one a "universe of the girl" of the original - but we live Only in the world where one of these results occurred. "And in every universe, there is a copy of you witness one or another result, from thought, incorrectly, your reality is the only reality"writing Physicist of Columbia University Brian Greene. But who really knows? Anybody.

Paul Steinhardt and Princeton Neil Turk from the University of Princeton, the Institute of Scope of Theoretical Physics in Ontario, Canada, suggested this concept, in which more dimensions exist that three of the space and one of the time. Greene puts it in this way: "Our universe is one of the potentially numerous" slabs "in a dimensional upper space, a bit like a slice of bread in a cosmic grandfather."

The big bang is still wrapped in mystery, but it's doubly true ofThe big crunch-The final theory of all that indicates that the continued expansion of the universe will finally conical and give way to gravity. In other words, all the mass in the universe (and potential multivators) will be drawn into an ever smaller space until it exists in an unimaginently dense and hot point - then is eliminated.

It sounds unpleasant, safe, but good! This will probably not happen for a few quadrillion years! And for more amazing facts that look like something a sci-fi novel, do not miss these20 long-standing predicted technologies that will never happen.
