Dust of the universe: feb 5, 2014

National Geographic presents the first accurate non-stop voyage from Earth to the edge of the Universe using a single, unbroken shot through the use of spectacular CGI Computer-Generated Imagery technology. Building on images taken from the Hubble telescope, Journey to the Edge of the Universe explores the science and history behind the distant celestial bodies in the solar system.

This spectacular, epic voyage across the cosmos, takes us from the Earth, past the Moon and our neighboring planets, out of our Solar System, to the nearest stars, nebulae and galaxies and beyond - right to the edge of the Universe itself.

When you finish this video, you will walk away from it with an awareness that you never had before, of the unseen astronomically massive universe that we float around on like a spec of dust in the ocean. This video takes you on a journey through the universe as if you are watching a Sci Fi adventure. Yet you constantly have to remind yourself that what you're seeing is really out there. Just as amazing as this film is, the scope, depth and sincerity of the comments are just as amazing.

In some parts is comical but overall an interesting perception of how it all began. Beautiful, just beautiful. Not enough words can describe the miracle that life is.

From the infinite small to the infinite big. There is a whole universe in every cell of our body, just like we are part of a bigger cell, in a bigger entity. Suddenly you realize how all this mundane life we lead and all the wars and hate on our planet seem so useless and infinitely small in the bigger picture.

I found this after smoking weed one night by accident and it was one of the most amazing things I'd ever seen. It never lost my attention whatsoever.

I've watched it five times in total soberI love it and show as many friends as I can. This is probably the greatest documentaries I;ve ever seen though I can't watch it unless it's Sean Pertwee's narration.

I love this documentary. Not for the science but the sense of adventure by being guided by Sean Pertwee I preferred him to Awec Bawdwin through a visually stunning universe. Anyone know of other docs like this one since now I pretty much know it off by heart? If you want to make a point find someone who has at least average to above average intelligence then have them write it.Some serious health risks appear for astronauts living on a lunar base or going on deep space missions.

10 Astronaut Health Risks That Threaten Deep Space Missions

A study on 12 astronauts found that the heart becomes 9. This could cause heart problems, especially on a deep space flight to Mars. So far, the change in shape reverts after the astronauts come back to Earth.

But no one knows what the long-term effects will be. Doctors already know that astronauts experience dizziness when they return to Earth.

Sometimes, a sudden blood pressure drop will cause them to pass out when they stand up. Some astronauts also experience arrhythmia in space. The researchers need to devise exercise regimens to keep deep space astronauts safe from these effects. Certain people on Earth, such as those on bed rest or with heart failure, may also benefit from this kind of exercise. A new five-year study is also underway to determine if space may speed up the development of atherosclerosis in astronauts.

Although NASA conducted an anonymous health care survey on its astronauts and ultimately dismissed concerns about excessive drinking, allegations were made in that drunk NASA astronauts were permitted to fly on the space shuttle and a Russian Soyuz spacecraft in two separate incidents.

This happened even though flight surgeons and other astronauts allegedly brought their safety concerns to local managers. The policy was supposed to apply to spaceflights, too. One retired astronaut, Mike Mullane, said some astronauts drink alcohol before a flight to dehydrate themselves and make the countdown to launch more comfortable on their bladders.

Psychological issues have also occurred in space. On the Skylab 4 mission, astronauts got so testy with mission control that they turned off their radio and ignored NASA for a day. Researchers are now studying the potential effects of a longer, more stressful deep space mission to Mars.

Three out of four also use sleep medicationswhich may be dangerous when operating the spacecraft or other equipment. This is particularly concerning if all the astronauts on a mission take the same drug at the same time, especially if they must awaken for an emergency alarm. NASA schedules 8.

They also get less than 6. Charles Czeisler. Studies have shown that even one shuttle mission could cause a substantial temporary hearing loss and a smaller permanent hearing loss, usually at the higher frequencies involved in hearing speech.

Crews aboard the Soviet Salyut 7 and the Russian Mir space stations also registered temporary and permanent hearing losses after they returned. Again, higher frequencies were most affected. On the International Space Station, astronauts initially had to wear ear plugs all day.

But NASA developed ways to reduce the noise levels with acoustic padding for the walls and quieter fans, among other measures. Besides the noise levels, other factors that may contribute to hearing loss in space include atmospheric contaminants, higher intracranial pressure, and greater carbon dioxide levels.As draws to a close, we once again cast our thoughts to all things astronomical for the coming year.

Events selected run the gamut from conjunctions and eclipses that are visible worldwide or over a good swath of the planet, to asteroid occultations of stars that are only visible along a thin path along the surface of the Earth. Geocentric conjunction times for occultations are quoted. As always, we look at the coming year with an eye out for the astronomically curious and the bizarre. A big bright one could come up and steal the show at any time! A full resource list, both paper and cyber, is given at the end of the post.

February is the only calendar month which can be missing the same moon phase twice! And while there are no total solar eclipses inthere are two fine total lunar eclipses, both visible from North America. Favorable inwith the Moon a 2 day old waxing crescent. It may be just possible to spot it five degrees north of the solar limb from high northern latitudes. This is a unique, non-central antumbral eclipse! Best observed from the Atlantic Region.

Favorable inwith the 7-day old Moon at waxing gibbous. This is t he only triple shadow transit for Optimal inas the Moon is at New phase. The Moon reaches Full 21 hours prior to perigee. Time variable, favorable in with the waxing crescent Moon 4 days past New.

Dark energy—a mysterious force that causes matter to accelerate away from other matter—is a case in point. It fuels the expansion of our universe, but it's an oddly small force. But if it were bigger and caused matter to fly apart any faster, you would not be here to read these words.

On Feb. They relayed how cosmologists are observing supernovae, galaxy clusters, large-scale structures and the cosmic microwave background to better understand the nature and evolution of dark energy. In addition, they investigated dramatic new ideas about space and time to answer deep questions raised by dark energy's very existence. Dark energy doesn't just exist—it dominates. Only 5 percent of the universe is ordinary matter.

Another 25 percent is dark matter—matter that scientists cannot "see" but whose existence is suggested because of the effects of its gravity on the rotation and clustering of galaxies. A whopping 70 percent of the universe is dark energy. When the universe expands, the particles of matter dilute, or take up less space in a given volume.

Ordinary energy, therefore, dilutes when the universe expands. In contrast, dark energy—also called vacuum energy—is a property of empty space. When empty space expands, it just replaces itself with more empty space; it does not dilute. So dark energy is a form of energy that does not dilute as the universe expands. Enter string theoryDark energy has the effect of a kind of "anti-gravity," causing everything to repel from everything else.

This force is inevitable in physicists' equations, but it's many, many, many orders of magnitude smaller than can be explained by standard theories. Enter string theory, which Susskind and Yoichiro Nambu proposed in While we observe three dimensions of space and one of time, string theory posits 10 dimensions of space and one of time.

The extra dimensions are balled up, or compactified, into dimensions too small to detect but whose structures are important to the laws of physics. Describing compactified dimensions is complex—to say the least. The answer can be as high as —[there are] huge, huge numbers of possibilities for the ways the atoms organize themselves. In the same way, there are huge numbers of possibilities for the way that these—they're called compactification manifolds—organize themselves. And because there are so many ways, there are many, many energy levels.

For the molecule, there are many, many possible values for the energy, possible values of the vacuum energy.

Duststorm - Transformers Universe - Decepticon Introduction

In recent years, some physicists have suggested that rather than having one universe with one set of physical laws, string theory may lay the foundation for the possibility of the existence of innumerable "pocket universes," each with its own landscape of physical laws.

So we now need a plural for the concept if we believe that space is filled like a crazy quilt of environments with different properties and different laws of physics. The number of possible energy states——inherent in string theory is "totally unexpected," Susskind said. Ed Witten [a physicist famed for his mathematical prowess] worked very hard to show that there was only a very small number, and he failed—failed completely.

Said Susskind: "More and more as time goes on, the opponents of the idea admit that they are simply in a state of depression and desperation. More and more people are starting to think about this possibility. But it's been a major sea change in the attitudes of theoretical physicists.

We have a basic set of precise concepts to think about it, and it means that in time we will know the truth.All rights reserved. In this infrared image, stellar winds from a giant star cause interstellar dust to form ripples. There's a whole lot of dust—which contains oxygen, carbon, iron, nickel, and all the other elements—out there, and eventually some of it finds its way into our bodies. Astrophysics and medical pathology don't, at first sight, appear to have much in common.

What do sunspots have to do with liver spots? How does the big bang connect with cystic fibrosis? Talking from their home in Palo Alto, California, they explain how everything in us originated in cosmic explosions billions of years ago, how our bodies are in a constant state of decay and regeneration, and why singer Joni Mitchell was right. Iris: Was she ever!

Everything we are and everything in the universe and on Earth originated from stardust, and it continually floats through us even today. It directly connects us to the universe, rebuilding our bodies over and again over our lifetimes. That was one of the biggest surprises for us in this book. We really didn't realize how impermanent we are, and that our bodies are made of remnants of stars and massive explosions in the galaxies.

All the material in our bodies originates with that residual stardust, and it finds its way into plants, and from there into the nutrients that we need for everything we do—think, move, grow.

And every few years the bulk of our bodies are newly created. Karel: When the universe startedthere was just hydrogen and a little helium and very little of anything else. Helium is not in our bodies.

Hydrogen is, but that's not the bulk of our weight. Stars are like nuclear reactors. They take a fuel and convert it to something else. Hydrogen is formed into helium, and helium is built into carbon, nitrogen and oxygen, iron and sulfur—everything we're made of. When stars get to the end of their lives, they swell up and fall together again, throwing off their outer layers. If a star is heavy enough, it will explode in a supernova. So most of the material that we're made of comes out of dying stars, or stars that died in explosions.

And those stellar explosions continue. We have stuff in us as old as the universe, and then some stuff that landed here maybe only a hundred years ago. And all of that mixes in our bodies. Your book yokes together two seemingly different sciences: astrophysics and human biology. Describe your individual professions and how you combined them to create this book. Iris: I'm a physician specializing in genetics and pathology.

Pathologists are the medical specialists who diagnose diseases and their causes. We also study the responses of the body to such diseases and to the treatment given. I also provide patient care by diagnosing inherited diseases and also cancers, and by following therapy responses in those cancer patients based on changes that we can detect in their DNA. Our book is based on many conversations that Karel and I had, in which we talked to each other about topics from our daily professional lives.

Those areas are quite different.

Journey to the Edge of the Universe

I look at the code of life. He's an astrophysicist who explores the secrets of the stars. But the more we followed up on our questions to each other, the more we discovered our fields have a lot more connections than we thought possible.

Karel: I'm an astrophysicist.I have been flying an Aircross Ucross for the past 2 years but I'm now looking for a more relaxed glider, a bit more comfort in thermic air but dont wish to comprises to much on the handling. Hi Tom, The UCross handling is unique You cannot compare it to the Rush 4,which has also a very good handling but very different The Ucross handling is toward some acro maneuvers.

The overall performance and efficiency of R4 is slightly better climb and glide. And it is more comfortable to fly than a Ucross and a Blacklight but less than a Mentor 3. Trim speed is not fast like a Ucross! I think you won't have any problem flying the R4.

Try one loaded at max! Happy flights. So the Carrera is not close enough for comparison??

B1424 code

I look forward to hearing your finishing tests. Hi Johnna, Fashion has eventually caught our little paragliding community Making a 6. The Carrera is a very good glider,but they could easily managed to increase some top end speed and let it float in the C category where it should really be!

Despite that many pilots bought the Carrera and some quickly sold it after As it requires more skill level for B pilots. Some will be content. It is like fitting an 8. According to the manufacturer and confirmed by our own testing this glider addresses experienced C pilots exclusively and is no replacement for the standard B -class-glider of the same manufacturer ;- To measure the performance of the Carrera with the Rush 4 is the same when comparing a Delta 2 with the Rush 4!

Many professionals are aware that they could somehow fit an EN-D glider on the B category But there will be a slaughter :- Here i have said it Good post Slingshot Kites. Could you do a quick comparison between Alpina2 and Rush4 comfort, handling and difference in Performance.

Thank you for all your great work. We appreciate it very much. Thanks for your review. I am a confident intermediate pilot living in the mountains of Colorado and flying a Buzz Z3, and flying weight is kg with gear. Hi Chris, Yes the Rush 4 could be a good option if you want to go for a high-end B.
