Thunderbolts the Electric Universe and Plasma Physics

Thunderbolt the Tutorial is about the electrical model of the universe. In the universe plasma makes up 99.99% of everything we can see. Our current model has big flaws that has forced scientist to dream up things that don't exist in order to explain things that we see out there in space. Yet the electrical model can explain most of these things. So why don't we hear about this model? It's not mentioned on TV shows like The Universe or How The Earth Was Made, Discovery Channel, or even PBS, never talk about it, WHY? Electricity, that's why! If the universe has electrical currents flowing thru it, and it does, then it's just a matter of time before we would learn how to harness that energy. You would have to buy a devise that would output the power, but after that it would be free. Imagine being able to drive anywhere you wanted to without having to stop and fill up your tank every 200 or 300 miles. Imagine your home when it's 110 degrees outside, but inside a nice 75 degrees with no electric bill to eat up all your hard earned money. Could it be true? I believe it could, and this would defiantly be a reason for the energy companies to not want this known. _____________________________________________________ Related videos: The truth about dark energy, it's really zero point energy. http://www.youtube.com/watch?v=EqaLSulA_3I A short 10 min video about the electrical universe and plasma physics. http://www.youtube.com/watch?v=gPiGWIf3FjA Dr. Chuck Missler on The Electric Universe 1hr 43min lecture. http://www.youtube.com/watch?v=mxLn06k2ATo Wallace Thornhill on the misconceptions of the electrical universe 13 min. http://www.youtube.com/watch?v=aa9tsMztZPY Universe - The Cosmology Quest Pt 1 http://www.youtube.com/watch?v=L6EGpg_BVBg&feature=channel_video_title Universe - The Cosmology Quest Pt 2 http://www.youtube.com/watch?v=t7uT0JuKT8Q&feature=relmfu ______________________________________ For more informative videos like this one: http://youtube.com/davnxs http://youtube.com/thetruthalwaysaddsup _____________________________________ Now you can add my Playlist to your Channel.

Space Odyssey: Voyage To The Planets 1 - BBC

Space Odyssey: Voyage To The Planets This two-part science fiction docu-drama examines the possibilities of a dangerous, manned space mission to explore the inner and outer planets of the Solar system. Five astronauts pilot the nuclear thermal rocket powered Pegasus spacecraft on a tour of the solar system. Their mission is a collaboration of the NASA, CSA, ESA and РКА space agencies and takes the crew to Venus, Mars, a close flyby of the Sun, Jupiter's moon Io and Europa, Saturn, Pluto, and the fictional Comet Yano-Moore. Most of the planetary destinations the crew reaches are followed by a manned landing there. Prior to the mission large tanks of hydrogen were deposited in stable orbits around the planets to allow the crew to refuel to have sufficient delta-v for the multi-year mission. The crew encounter many hardships and disappointments along the way. A Venus EVA that almost ends in disaster when the lander Orpheus encounters launch delays, the near-loss of the shield during the aerobrake in Jupiter's upper atmosphere (according to the first part of the miniseries) and the loss of samples from Jupiter's moon Io all test the crew's resolve. The most devastating blow comes when the ship's medical officer dies of solar radiation-induced lymphoma in Saturn orbit, forcing the crew to decide whether to continue the mission to Pluto, or abort and return to Earth. In the original British release, the crew decides to press on to Pluto, making history.

5-times size of Earth: Giant solar tornado caught in rare NASA tape (VIDEO).mp4

For more exclusive information on UFOs, visit: http://erigia.blogspot.com/2012/05/les-theories-du-complot-revendication.html 5 fois la taille de la Terre: Géant tornade solaire pris dans la NASA cassette rare (VIDEO): Une tornade géante solaire - cinq fois le diamètre de la Terre - tourbillonnant à la vitesse incroyable de certains mph 186000 a été capté sur vidéo par l'Observatoire de la NASA Solar Dynamics. C'est la première fois un géant solaire twister a été capturé sur vidéo. Tornades solaires, connus sous le nom des protubérances solaires, sont façonnées par le champ magnétique du soleil et se produisent souvent pendant les éjections de masse coronale - explosions énormes de plasma solaire. La vitesse de gaz tourbillonnant solaires peut parfois atteindre plusieurs milliers de miles par heure. Cette tornade 124 000-mile de haut a été filmé le 25 Septembre 2011, mais la vidéo n'a été rendu public lors de la réunion national d'astronomie à Manchester (Royaume-Uni) le jeudi. Xing Li, un astronome de l'Université d'Aberystwyth au Pays de Galles, estime que le constat est un "vrai petit bijou d'un événement de frapper l'imagination, et il est un bon moyen d'étudier les structures magnétiques dans l'atmosphère du soleil." Les scientifiques pensent que l'étude de tornades solaires permettra de comprendre les causes des tempêtes de l'espace en général, qui est encore l'un des grands mystères de notre système solaire. ---------------------------------------------------------------------------------------------- A giant solar tornado - five times the Earth's diameter - swirling at incredible speed of some 186,000 mph has been captured on video by NASA's Solar Dynamics Observatory. ­This is the first time a giant solar twister has been caught on video.

Which telescope to buy?

Below are some of the telescopes I've used in recent years, ranging from ~30 -3000 dollars. (shortened for YTs character limits) Price $35 76mm reflector dobsonian mounted (Celestron Firstscope) Weight ~ 1kg (a couple of pounds) Setup time ~0 East of Transport 1 Short focal length- wide angle field of view. Finder not really necessary. Ultra cheap, good views of Moon, Jupiter Venus, rings of Saturn, bright, wide separation double stars, and brighter deep sky objects such as M13. I was not particularly impressed with the optics on mine, but for 35 bucks, you cant complain too much! Price $200 90mm Maksutov-Cassegrain, dobsonian mount (Orion Apex) Weight ~ 1kg (a couple of pounds) Setup time ~0 East of Transport 1 Longer focal length means smaller field of view for comparable eye pieces. I was impressed with this scope on the planets. It vastly outperforms the Firstscope on optics. The scope comes off the dobsonian mount on a quick release and can be mounted as a spotter scope (the main reason I got it). The dobsonian mount here (one arm) is exactly the same as the mount for the Firstscope. These are sort of the poor mans refractor. Great views of Moon and all the bright planets. Picked out Titan (brightest moon of saturn) with ease. I got this telescope for two reasons, firstly for outreach, in that you can just grab it and point it in seconds, zero setup time. Secondly I can mount it piggyback on the CPC11 (see below) and use it as a spotting/ guide scope. The Maksutov has the 'nice' feature that its a closed tube(helps keep dust out). The Mak. will have the edge on planets/ guidescope etc due to its longer focal length, but the Newtonian will be more all around bang for the buck. Price $600 10in Newtonian reflector, dobsonian mount (Celestron Starhopper) Weight ~ 15kg (~30lbs) Setup time ~10 mins to carry parts outside, 10 mins + cool down. East of Transport: Telescope is about the size of a small child (although not that heavy). It is big and awkward. Difficult to handle for the small. Almost the biggest telescope you can fit in a compact car (the reason I got it). The long open optical train requires periodic alignment (columniation) if it is frequently transported. Powerful deep-sky scope. Near zero photographic potential, but fantastic views of nebula, globular clusters and galaxies. Great scope for planets too. At this size the moon is getting too bright to look at for any length of time. Like most big newtonians, short focal ratio, which pragmatically means you get quite wide angle views. Again well suited to deep sky observing. Price $1500 90mm (3.5in) Stellarvue apochromat, -no mount, tube only (Apo Triplet) Weight ~ 4kg (~8lbs) East of Transport: The telescope is small and easy to transport. Comes with a bag that will go on an airplane as hand baggage. Worth the price for the aperture? Probably not unless you are in a fairly specific niche. This makes a great wide angle lenses for guided photography. As a guidescope its focal length is kind of short. That basically means the field of view for a given eye piece is wide. You need a very short focal length eye piece to get good magnification. I found myself using a 4mm eyepiece to look at planets, and even at that the image was small. As a finder scope though, that wide field is great. The other thing that these scope gives is absolutely beautiful stellar images. The stars just fall into incredible pin pricks. Beautiful contrasty flat views. I found the use of the short focal length eyepieces annoying for planetary use. Lacks the light gathering for versatility as a deep sky instrument. I only really ever used this as a piggybacker for the CPC11 below. Price $2800 11in Schmidt Cassegrain, driven goto alt-az fork mount (CPC11) Weight ~ 30kg (~65lbs) and thats just the top section. Tripods another 15 kg I think. Setup time ~30 mins to carry parts outside and align, 20 mins + cool down. East of Transport: It will fit in a compact car. To carry the telescope any distance really isnt an option unless you are strong. The ergonomic design is very good though. I always found mounting up the scope a bit of a bitch. Aligning it is relatively easy as the scope mount has a GPS in it that means you dont have to plug in these numbers and the time. Alignment is quite easy. I found the scope slips relatively easily unless the clutches are done up very tight. The scope can carry quite a burden (although of course when the scope weights this much extra, it does need to be well balanced). At this level it is an excellent photographic platform. It yields amazing views of almost everything. It's photographic potential is probably as good as you can get from a portable platform. This is the instrument I used to do the full rotation of Jupiter, although there the primary limitation was the stability of the sky.

Tornado on the Sun Vast 300,000mph Planet-Sized

A tremendous tornado whirling across the surface of the sun was captured by a NASA satellite recently -- an amazing wonder of the solar system that may be as big as the Earth itself. The video was recorded by the Solar Dynamics Observatory (SDO), a sun-watching satellite that has transmitted a series of stunning photos of solar flares in recent months. The new video shows darker, cooler plasma shifting back and forth above the sun's surface over the span of nearly 30 hours stretching from Feb. 7 to Feb. 8. And the giant tornado may be as large as the Earth itself, with gusts of up to 300,000 mph, explained Terry Kucera, deputy SOHO project scientist and a solar physicist with NASA's Goddard Space Flight Center. "It's about 15,000 degrees Fahrenheit -- relatively cool," Kucera told FoxNews.com. After all, the sun's corona is a whopping 2 million degrees, she explained. Such tornadoes (Kucera classed it a "solar prominence") have been known of for decades; the European Space Agency's SOHO spacecraft captured evidence of them as early as 1996, mainly near the Sun's north and south poles at the time. And though they resemble their cousins here on Earth, they're created entirely differently, Kucera said -- through magnetism, not pressure and temperature fluctuations. "Those motions you see, it's all just moving along the magnetic field somehow -- but we're still looking to understand what's happening with these things," Kucera said. The storm was created by competing magnetic forces, which pull the charged magnetic particles on the sun back and forth, creating a spinning mass of plasma that tracks along strands of magnetic field lines, NASA explained. The spinning top of the tornado is mesmerizing, but Kucera noted the span of the prominence as well. The long, ribbon shapes could span hundreds of thousands of miles, she said. "In total length, this could be dozens of Earths -- quite large," she said. Such detailed, high-resolution recordings of the immense tornadoes was not possible until the launch of SDO. The satellite has several cameras on board that capture solar activity in different wavelengths and frequencies, all in the name of science. "Each wavelength of light tells us something different," she said.

Wandering Stars: a tour of the planets

A beauteous rip through the solar sytem, based on NASA's Science on a Sphere program "The Wanderers." In ancient times, humans watched the skies looking for clues to their future and to aid in their very survival. They soon observed that some stars were not fixed, but moved in the sky from night to night. They called these stars the wanderers. At the center of our solar system is the sun, binding the planets with its gravitational pull. From our viewpoint on earth, the sun appears small in the sky, but in reality it dwarfs even Jupiter, the largest planet in the solar system. The distance from the sun to the small worlds traveling it are vast. Light takes eight minutes to reach earth, and nearly a day to reach the farthest known bodies. Join us now as we tour our solar system, starting with sun-baked mercury and traveling to the remotest outskirts, where small, icy bodies move with only the faintest connection to our sun. Mercury Mercury, the closest planet to Sun is also the smallest terrestrial planet. It orbits so swiftly that its year lasts only 88 Earth days. The airless cratered surface could almost be mistaken for our moon, relentlessly bombarded by meteoroids for four and a half billion years. One of these encounters left a giant scar called the golarus basin, one of the largest impact sights in the solar system. Temperatures on the surface of mercury can reach a blistering 800 degrees Fahrenheit, and can dip to 300 degrees below zero on the night side. Venus Venus, as seen from Earth, is the brightest object in sky after the Sun and Moon. Russian probes were the first to land on Venus in the 1970's and 1980's. Venus's surface is volcanic. Its atmosphere is composed of thick, dense carbon dioxide with sulfuric acid clouds. Both are potent greenhouse gases that trap incoming sunlight. Venus rotates slowly—one Venusian day lasts almost four Earth months. Earth Earth is the only planet with life as we know it. The atmosphere and temperatures are "just right" for life. It is the only known body in our solar system where water can exist as a gas, liquid, and solid. Vast oceans dominate surface of the planet. Seasonal changes occur on the surface. Earth has a solid surface that constantly shifts due to plate tectonics. Mars Once geologically active, Mars has the largest dormant volcano in the solar system, Olympus Mons. It also hast the longest valley in the solar system, called Valles Marineris. Mars has a thin, atmosphere primarily composed of carbon dioxide. Surface conditions are dynamic. Mars has seasons as well as massive dust storms that cover the planet. Its surface features include the smooth, low-lying northern hemisphere and the craggy, heavily-cratered southern uplands. Evidence suggests that Mars had water running on its surface at some time in the past. Asteroid belt The asteroid belt is composed of small rocky pieces. The big question is "What happened here?" and "Why no planets?" The asteroid Ceres is large enough to be classified as a dwarf planet. Jupiter Jupiter is the largest and most massive planet in the Solar System. It rotates rapidly, completing one rotation every 10 hours. Long-lasting, high-speed winds and storms dominate Jupiter's atmosphere. Jupiter has a faint planetary ring system and over 63 moons. The largest moons, discovered by Galileo in 1610, vary widely. Io is volcanically active. Europa's cracked surface likely hides an ocean below. Ganymede is the largest moon in the Solar System. Callisto is heavily cratered. Saturn Saturn's seemingly serene atmosphere hides powerful storms and winds on its surface. Saturn is known for its extensive ring system made of chunks of ice, rock, and dust with small moonlets embedded within the rings. Saturn has more than 60 moons. Conditions vary among the moons. Titan, the largest moon, has a thick, smoggy, atmosphere covering its icy surface with lakes of liquid methane or ethane. Small Enceladus has water and ice geysers at its south pole. Its water vapor coat other nearby moons and create a thin Saturn ring. Uranus Uranus receives 400 times less sunlight than Earth. Uranus lies nearly sideways, making its axis nearly parallel to the plane of the Solar System. This extreme tilt give rise to seasons that last nearly 28 Earth years. Uranus as many moons and a faint ring system. It has only been visited by one spacecraft, Voyager 2, in 1986. Like the other giant planets, Uranus's atmosphere is primarily hydrogen and helium with a trace of methane gas over deep clouds, giving it a pale blue-green tint. Neptune Neptune also has many moons and a faint ring system. Its Great Dark Spot, a large storm with extremely strong winds, disappeared in the 1990s. Neptune's vivid blue color is due to its frigid temperature: -371°F (-224 °C).

Big New ExoPlanet Haul

From EsoCast in 1080p, comes the announcement of a rash of new planet discoveries. Astronomers using ESO's leading exoplanet hunter HARPS have today announced more than fifty newly discovered planets around other stars. Among these are many rocky planets not much heavier than the Earth. One of them in particular orbits within the habitable zone around its star. Among the new planets just announced by scientists, sixteen are super-Earths - rocky planets up to ten times as massive as Earth. This is the largest number of such planets ever announced at one time. A planet in orbit causes its star to regularly move backwards and forwards as seen from Earth. This creates a tiny shift of the star's spectrum that can be measured with an extremely sensitive spectrograph such as HARPS. In their quest to find a rocky planet that could harbor life, astronomers are now pushing HARPS even further. They have selected ten well-studied nearby stars similar to our Sun. Earlier observations showed that these were ideal stars to examine for even less massive planets. After two years of work, the team has found five light super-Earths around three of the stars. These planets are very good candidates for future observations looking for evidence of life. One of the newly found planets, named HD 85512 b, orbits inside the habitable zone. This is the narrow area around a star where water can exist in liquid form. Astronomers estimate that liquid water could possibly be present on this planet if it is a rocky world that has more than 50% cloud cover. By looking carefully at the results from the first 8 years of HARPS observations, the team has found that around 40% of stars similar to the Sun harbor at least one planet lighter than Saturn. These new results lead astronomers to believe that they could soon find more super-Earths in the habitable zones of their stars with HARPS. These planets will be great targets for powerful future telescopes to try to study their atmospheres looking for evidence of life. Thanks to HARPS, the search for another Earth elsewhere in the galaxy is picking up pace!

Planet-Sized Tornado Whirls On Sun's Surface 2012 HD

A tremendous tornado whirling across the surface of the sun was captured by a NASA satellite recently an amazing wonder of the solar system that may be as big as the Earth itself. The video was recorded by the Solar Dynamics Observatory (SDO), a sun-watching satellite that has transmitted a series of stunning photos of solar flares in recent months. The new video shows darker, cooler plasma shifting back and forth above the sun's surface over the span of nearly 30 hours stretching from Feb. 7 to Feb. 8.

PREVIEW: Alien Planets & Eyeball Earths

Music by Zero Project. The hunt for planets beyond our solar system has reached a fever pitch. With some 500 planets revealed by ground telescopes, now, the ultimate planet finder, the Kepler space telescope, has released a tsunami of data. Among over a thousand new planet prospects are 200 multi-planet solar systems and 58 worlds in life-friendly orbits. They're all within a narrow window on the sky the size of your hand. That's why this may be the tip of the iceberg in a galaxy that's literally crawling with planets. Scientists are now beginning to envision what these worlds are like, with atmospheres, oceans, geological history. In the process, they are redefining what a planet might need to spawn life.
