mysteries of a dark universe
Bookmarked 701 weeks ago watch this video commercial free on the spacerip app available in the apple and google play stores dark energy in full hd 1080p cosmology the study of the universe as a whole has been turned on its head by a stunning discovery that the universe is flying apart in all directions at an ever-increasing rate is the universe bursting at the seams or is nature somehow fooling usthe astronomers whose data revealed this accelerating universe have been awarded the nobel prize for physics and yet since 1998 when the discovery was first announced scientists have struggled to come to grips with a mysterious presence that now appears to control the future of the cosmos: dark energyon remote mountaintops around the world major astronomical centers hum along with state of the art digital sensors computers air conditioning infrastructure and motors to turn the giant telescopes deep in chile039s atacama desert the paranal observatory is an astronomical mecca this facility draws two megawatts of power enough for around two thousand homeswhat astronomers get for all this is photons tiny mass-less particles of light they stream in from across time and space by the trillions from nearby sources down to one or two per second from objects at the edge of the visible universein this age of precision astronomy observers have been studying the properties of these particles to find clues to how stars live and die how galaxies form how black holes grow and more but for all we039ve learned we are finding out just how much still eludes our grasp how short our efforts to understand the workings of the universe still fall a hundred years ago most astronomers believed the universe consisted of a grand disk the milky way they saw stars like our own sun moving around it amid giant regions of dust and luminous gas the overall size and shape of this quotisland universequot appeared static and unchangingthat view posed a challenge to albert einstein who sought to explore the role that gravity a dynamic force plays in the universe as a whole there is a now legendary story in which einstein tried to show why the gravity of all the stars and gas out there didn039t simply cause the universe to collapse into a heap he reasoned that there must be some repulsive force that countered gravity and held the universe uphe called this force the quotcosmological constantquot represented in his equations by the greek letter lambda it039s often referred to as a fudge factorin 1916 the idea seemed reasonable the dutch physicist willem de sitter solved einstein039s equations with a cosmological constant lending support to the idea of a static universenow enter the american astronomer vesto slipher working at the lowell observatory in arizona he examined a series of fuzzy patches in the sky called spiral nebulae what we know as galaxies he found that their light was slightly shifted in colorit039s similar to the way a siren distorts as an ambulance races past us if an object is moving toward earth the wavelength of its light is compressed making it bluer if it039s moving away the light gets stretched out making it redder 12 of the 15 nebulae that slipher examined were red-shifted a sign they are racing away from usedwin hubble a young astronomer went in for a closer look using the giant new hooker telescope in southern california he scoured the nebulae for a type of pulsating star called a cepheid the rate at which their light rises and falls is an indicator of their intrinsic brightness by measuring their apparent brightness hubble could calculate the distance to their host galaxies combining distances with redshifts he found that the farther away these spirals are the faster they are moving away from us this relationship called the hubble constant showed that the universe is not static but expandingeinstein acknowledged the breakthrough and admitted that his famous fudge factor was the greatest blunder of his career |

the riddle of antimatter
Bookmarked 701 weeks ago watch this and other space videos at http:spaceripcomin high-res 1080p explores one of the deepest mysteries about the origin of our universe according to standard theory the early moments of the universe were marked by the explosive contact between subatomic particles of opposite charge featuring short interviews with masaki hori tokyo university and jeffrey hangst aarhus universityscientists are now focusing their most powerful technologies on an effort to figure out exactly what happened our understanding of cosmic history hangs on the question: how did matter as we know it survive and what happened to its birth twin its opposite a mysterious substance known as antimatter a crew of astronauts is making its way to a launch pad at the kennedy space center in florida little noticed in the publicity surrounding the close of this storied program is the cargo bolted into endeavor039s hold it039s a science instrument that some hope will become one of the most important scientific contributions of human space flightit039s a kind of telescope though it will not return dazzling images of cosmic realms long hidden from view the distant corners of the universe or the hidden structure of black holes and exploding starsunlike the great observatories that were launched aboard the shuttle it was not named for a famous astronomer like hubble or the chandra x-ray observatorythe instrument called the alpha magnetic spectrometer or ams the promise surrounding this device is that it will enable scientists to look at the universe in a completely new way most telescopes are designed to capture photons so-called neutral particles reflected or emitted by objects such as stars or galaxies ams will capture something different: exotic particles and atoms that are endowed with an electrical charge the instrument is tuned to capture quotcosmic raysquot at high energy hurled out by supernova explosions or the turbulent regions surrounding black holes and there are high hopes that it will capture particles of antimatter from a very early time that remains shrouded in mysterythe chain of events that gave rise to the universe is described by what039s known as the standard model it039s a theory in the scientific sense in that it combines a body of observations experimental evidence and mathematical models into a consistent overall picture but this picture is not necessarily completethe universe began hot after about a billionth of a second it had cooled down enough for fundamental particles to emerge in pairs of opposite charge known as quarks and antiquarks after that came leptons and antileptons such as electrons and positrons these pairs began annihilating each othermost quark pairs were gone by the time the universe was a second old with most leptons gone a few seconds later when the dust settled so to speak a tiny amount of matter about one particle in a billion managed to survive the mass annihilation that tiny amount went on to form the universe we can know - all the light emitting gas dust stars galaxies and planets to be sure antimatter does exist in our universe today the fermi gamma ray space telescope spotted a giant plume of antimatter extending out from the center of our galaxy most likely created by the acceleration of particles around a supermassive black hole the same telescope picked up signs of antimatter created by lightning strikes in giant thunderstorms in earth039s atmosphere scientists have long known how to create antimatter artificially in physics labs - in the superhot environments created by crashing atoms together at nearly the speed of lighthere is one of the biggest and most enduring mysteries in science: why do we live in a matter-dominated universe what process caused matter to survive and antimatter to all but disappear one possibility: that large amounts of antimatter have survived down the eons alongside matterin 1928 a young physicist paul dirac wrote equations that predicted the existence of antimatter dirac showed that every type of particle has a twin exactly identical but of opposite charge as dirac saw it the electron and the positron are mirror images of each other with all the same properties they would behave in exactly the same way whether in realms of matter or antimatter it became clear though that ours is a matter universe the apollo astronauts went to the moon and back never once getting annihilated solar cosmic rays proved to be matter not antimatterit stands to reason that when the universe was more tightly packed that it would have experienced an quotannihilation catastrophequot that cleared the universe of large chunks of the stuff unless antimatter somehow became separated from its twin at birth and exists beyond our field of view scientists are left to wonder: why do we live in a matter-dominated universe |

saturn039s mysterious moons
Bookmarked 709 weeks ago watch in high-resolution 1080p launched three years before the new century a spacecraft wound its way through the empty reaches of the solar system on earth its progress was little noted as it swung twice by the planet venus then our moon and earth the asteroid belt and jupiteralmost seven years later on the first of july 2004 the cassini probe entered the orbit of saturn it then began to compile what has become one of the greatest photographic collections of all time of a giant gas planet surrounded by colorful rings guarded by a diverse collection of moons and millions of tiny moonlets within this record is a trail of clues pointing to the energy sources and complex chemistry needed to spawn life what are these mysterious worlds telling us about the universe and earth in the outer reaches of the solar system a billion and a half kilometers from the sun there is a little world known as enceladus nearly all of the sunlight that strikes its icy surface is reflected back into space making it one of the brightest objects in the solar systemat its equator the average temperature is minus 198 degrees celsius it can rise about 70 degrees higher in grooves that stretch across the south pole like tiger stripes looming over it is the giant planet saturnin myth saturn - the roman name for the primal greek god chronos - was the youngest son of gaia or earth and uranus sky wielding a scythe provided by his mother the story goes saturn confronted his abusive father castrating him the blood of uranus flowed into the seas fertilizing the earth and giving rise to enceladus and other giant offspring saturn039s moon enceladus has its own tangled story in 2005 the cassini spacecraft spotted plumes of water vapor shooting out into space from its south pole more recent close encounters have revealed jets of water flavored by slightly salty chemical compounds spewing out from vents in the rough cracked polar terrain that may mean that enceladus harbors a remarkable secret below its frigid surface: a liquid ocean and perhaps a chemical environment that could spawn simple life forms it039s not the only promising stop in the realm of saturn the moon titan is often said to resemble earth in its early days it is lined with volcanoes and a hazy atmosphere rich in organic compounds while enceladus is the size of great britain titan is ten times larger 50 larger than our moon and the second largest moon in our solar systemwe039ve known about titan since the astronomer christian huygens discovered it in 1655 and enceladus since william herschel spotted it in august 1789 just after the start of the french revolution scientists began to investigate these moons in earnest with the launch of the two voyager spacecraft in 1977 the lineup of outer planets in the solar system allowed the spacecraft to fly past each of themthey disclosed new details about their magnetic fields atmospheres ring systems and inner cores but what really turned heads were the varied shapes and surfaces of their moons they039ve all been pummeled over the millennia by wayward asteroids and comets a few appear to be sculpted by forces below their surfaces neptune039s largest moon triton has few craters it039s marked with circular depressions bounded by rugged ridges there are also grooves and folds that stretch for dozens of miles a sign of fracturing and deforming triton has geysers too shooting some five miles above the surface but on this frigid moon -- so far from the sun -- the liquid that spouts is not water but nitrogen tiny miranda one of 27 known moons that orbit uranus wears a jumbled skin that039s been shaped and reshaped by forces within jupiter039s moon io -- orbiting perilously close to the giant planet is literally turning itself inside out rivers of lava roll down from open craters that erupt like fountains flying by europa voyager documented a complex network of criss-crossing grooves and ridges in the 1990s the galileo spacecraft went back to get a closer look it found that europa039s surface is a crazy quilt of fractured plates cliff faces and gullies amid long grooves like a network of superhighways how did it get like this then heat rising up through a subsurface ocean of liquid water cracks and shifts and spreads the icy surface in a thousand different ways europa039s neighbors callisto and ganymede show similar features suggesting they too may have liquid oceans below their surfaces crossing outward to saturn voyager found a similar surface on the moon enceladus so when the cassini spacecraft arrived in 2004 it came looking for answers to a range of burning questions: if this moon and others have subsurface oceans do they also have the ability to cook up and support life and what could they tell us about the origin of life throughout the galaxy |

2012 - the sun yellowstone and canaries - threat to our planet - captain bill
Bookmarked 696 weeks ago friends of our channel and youtubers welcomethis video is to alert you to the biggest natural problem that we may have this year 2012 the sun yellowstone and canariesafter mr michio kaku explanation about yellowstone now let039s talk about the supervolcano el hierro in the canary islands this volcano has intensified activities in a surprising way in 2011 was about to explode if not the interventions of our friends arcturians which caused the pressure relief on the ocean floor as shown in the pictures now as these interventions ceased nature should take its natural course the island has swelled five inches vertically and six inches horizontally this shows that the pressure is incredibly high on the caldera beneath the island if the worst happens a tsunami of epic proportions will cross the atlantic at up to 800km per hour in the directions of the three americas everything is 30 km from the coast will suffer the consequences the increase in volcanic activity on the planet are due directly to the great increase in the incidence of channeled energy from solar flares increasing the temperature of the core and the magma of the planet by a effect quotmicrowavequot the heated material expands creating a general instability in the tectonic plates of the planet as a whole the supervolcanoes are the exhaust valves of this huge pressure cooker and we expect them to trigger sooner or later if the solar activity continues to rise the way it is let039s hope for the best but nature should take its course as the designs attributed to our planet in this change of age the smaller volcanoes no less destructive for their large number are distributed in the contact zones of tectonic plates and these are increasingly unstable not only in the pacific ring of fire but on the whole planet this can lead to earthquakes of large proportions followed by localized tsunamis that just as the last of japan which can devastate coastal regions around the globe be at peace with your consciences because one thing the man has not yet learned to control the force of naturenow with respect to the government elite and its wars of interest and control we can get rid of them some time from now be surethanks for watching join our channel you are welcome to open mind therejuly - 2012 - captain bill - atlanticobr channel |
