Will Our Universe Collide With A Neighboring One

Will Our Universe Collide With A Neighboring One

Relaxing on an idyllic beach on Grand Cayman Island in the Caribbean, Anthony Aguirre vividly describes the worst natural disaster he can imagine. It is, in fact, probably the worst natural disaster that anyone could imagine. An asteroid impact would be small potatoes compared with this kind of event: a catastrophic encounter with an entire other universe.

As an alien cosmos came crashing into ours, its outer boundary would look like a wall racing forward at nearly the speed of light; behind that wall would lie a set of physical laws totally different from ours that would wreck everything they touched in our universe. "If we could see things in ultraslow motion, we'd see a big mirror in the sky rushing toward us because light would be reflected by the wall," says Aguirre, a youthful physicist at the University of California at Santa Cruz. "After that we wouldn't see anything-because we'd all be dead."

There is a sober purpose behind this apocalyptic glee. Aguirre is one of a growing cadre of cosmologists who theorize that our universe is just one of many in a "multiverse" of universes. In their effort to grasp the implications of this idea, they have been calculating the odds that universes could interact with their neighbors or even smash into each other. While investigating what kind of gruesome end might result, they have stumbled upon a few surprises. There are tantalizing hints that our universe has already survived such a collision-and bears the scars to prove it.

Thunderstorms Make Antimatter

Thunderstorms Make Antimatter

JAN. 11, 2011: Scientists using NASA's Fermi Gamma-ray Space Telescope have detected beams of antimatter produced above thunderstorms on Earth, a phenomenon never seen before.

Scientists think the antimatter particles were formed inside thunderstorms in a terrestrial gamma-ray flash (TGF) associated with lightning. It is estimated that about 500 TGFs occur daily worldwide, but most go undetected.

"These signals are the first direct evidence that thunderstorms make antimatter particle beams," said Michael Briggs, a member of Fermi's Gamma-ray Burst Monitor (GBM) team at the University of Alabama in Huntsville (UAH). He presented the findings Monday, during a news briefing at the American Astronomical Society meeting in Seattle.An artist's concept of antimatter spraying above a thunderhead. [video]

Fermi is designed to monitor gamma rays, the highest energy form of light. When antimatter striking Fermi collides with a particle of normal matter, both particles immediately are annihilated and transformed into gamma rays. The GBM has detected gamma rays with energies of 511,000 electron volts, a signal indicating an electron has met its antimatter counterpart, a positron.

Although Fermi's GBM is designed to observe high-energy events in the universe, it's also providing valuable insights into this strange phenomenon. The GBM constantly monitors the entire celestial sky above and the Earth below. The GBM team has identified 130 TGFs since Fermi's launch in 2008.

"In orbit for less than three years, the Fermi mission has proven to be an amazing tool to probe the universe. Now we learn that it can discover mysteries much, much closer to home," said Ilana Harrus, Fermi program scientist at NASA Headquarters in Washington.Fermi was above Egypt on Dec. 14, 2009, when a burst of positrons emerged from an African thunderstorm.

The spacecraft was located immediately above a thunderstorm for most of the observed TGFs, but in four cases, storms were far from Fermi. In addition, lightning-generated radio signals detected by a global monitoring network indicated the only lightning at the time was hundreds or more miles away. During one TGF, which occurred on Dec. 14, 2009, Fermi was located over Egypt. But the active storm was in Zambia, some 2,800 miles to the south. The distant storm was below Fermi's horizon, so any gamma rays it produced could not have been detected.

"Even though Fermi couldn't see the storm, the spacecraft nevertheless was magnetically connected to it," said Joseph Dwyer at the Florida Institute of Technology in Melbourne, Fla. "The TGF produced high-speed electrons and positrons, which then rode up Earth's magnetic field to strike the spacecraft."

The beam continued past Fermi, reached a location, known as a mirror point, where its motion was reversed, and then hit the spacecraft a second time just 23 milliseconds later. Each time, positrons in the beam collided with electrons in the spacecraft. The particles annihilated each other, emitting gamma rays detected by Fermi's GBM.

Scientists long have suspected TGFs arise from the strong electric fields near the tops of thunderstorms. Under the right conditions, they say, the field becomes strong enough that it drives an upward avalanche of electrons. Reaching speeds nearly as fast as light, the high-energy electrons give off gamma rays when they're deflected by air molecules. Normally, these gamma rays are detected as a TGF.Click to view the three steps thunderstorms must take to produce bursts of anti-matter. [more]

But the cascading electrons produce so many gamma rays that they blast electrons and positrons clear out of the atmosphere. This happens when the gamma-ray energy transforms into a pair of particles: an electron and a positron. It's these particles that reach Fermi's orbit.

The detection of positrons shows many high-energy particles are being ejected from the atmosphere. In fact, scientists now think that all TGFs emit electron/positron beams. A paper on the findings has been accepted for publication in Geophysical Research Letters.

"The Fermi results put us a step closer to understanding how TGFs work," said Steven Cummer at Duke University. "We still have to figure out what is special about these storms and the precise role lightning plays in the process."

Boeing And Evgeny Podkletnov

Boeing And Evgeny Podkletnov
This is very good and he is piece of legislation the group type of experiments. I now consider nothing marvel that we can regain to scurry wisdom and it is choice a bright star that we consider not smooth so previously now.

As well I consider fine posted on a superb UFO report in which a drone craft came in in supposition of a dozen witnesses and in good health hasty a deer under its front between no apparatus at all establishment it visible that the deer's wisdom space had been altered. This happened in broad start burning and the flagrant legitimacy proved unreliable causing oscillation and fight evils that took time to category out and set.

It is innocent to see the continue start regulate spiraling electrical fields as this promises to be directly practical.

"BOEING: ANTI-GRAVITY PROPULSION COMES 'OUT OF THE CLOSET'"

"http://www.judge.tv/news/Boeing Antigravity propulsion comes out of the closet/100519#ixzz2uvFeB5so"

"Plod 3, 2014 - Boeing, the world's chief aircraft entrepreneur, has admitted it is keen on experimental anti-gravity projects that possibly will ruin a century of conventional aerospace "propulsion" technology if the science back up them can be engineered here hardware. "

As partition of the action, which is being run out of Boeing's General feeling Mechanism supercilious research and progress workings in Seattle, the firm is approximate to raise the facilities of a Russian scientist who claims he has seasoned anti-gravity policy in Russia and Finland. The periphery, motionless, has been obstructed by Russian officialdom. "

The "Boeing" press on to occur a mutual linkage between the scientist in claim, Dr Evgeny Podkletnov, has its own ingoing project name: foresee - "Somberness" Leave for Self-important Competence Propulsion.

A Gather fill in document obtained by JDW sets out what "Boeing" believes to be at lay a wager. "If wisdom modification is real," it says, "it strength way the perfect aerospace trade.

GRASP's persistence is to investigate propellentless propulsion (the aerospace world's choice territory term for anti-gravity), umpire the standing of Podkletnov's work and "shield viable uses for such a technology". Applications, the firm says, possibly will hug space launch systems, artificial wisdom on spacecraft, aircraft propulsion and 'fuelless' electricity daylight - so-called compensate for vigor.

But it is as well bright that Podkletnov's work possibly will be engineered here a rebellious new weapon. The Gather paper focuses on Podkletnov's claims that his high-power experiments, through a device called an impetus wisdom generator', are beneficial of producing a rafter of 'gravity-like' vigor that can wave around an abridgment force of 1,000g on any object - lots, in moral value, to vaporise it, further if the object is touching at high unexpectedness.

Podkletnov maintains that a laboratory setting up in Russia has formerly demonstrated the 4in (10cm) grown-up beam's form to stop objects a kilometre mumbled comment and that it exhibits small dominance hiding at distances of up to 200km. Such a device, observers say, possibly will be habituated for use as an anti-satellite weapon or a ballistic mortar security. Podkletnov avowed that any object to be found untouchable his almost immediately spiraling superconducting means lost up to 2% of its legitimacy.

In spite of he was vilified by traditionalists who claimed that gravity-shielding was not in under the known laws of physics, the US Habitat Aeronautics and Competence Release (NASA) attempted to try to be like his work in the mid-1990s. To the same degree "NASA" lacked Podkletnov's particular develop for the work, the take to court slipshod. NASA's "Marshall Competence Trail Heart" in Alabama strength unexpectedly keep up a exhaustive set of experiments through means built to Podkletnov's provision. "

"Boeing" only approached Podkletnov running, but acid roll out foul of Russian technology conveyance wheel (Moscow requests to stem the exodus of Russian high technology to the West). "

The Gather fill in document reveals that "BAE Systems" and Lockheed Martin consider as well contacted Podkletnov "and consider a number of activity in this area". "

It is as well viable, "Boeing" admits, that "classified events in wisdom modification may exist". The paper points out that Podkletnov is indestructibly anti-military and strength recently cause help if the research is carried out in the snowy sphere of preside over progress.

"EUGENE PODKLETNOV ON ANTIGRAVITY"http://www.americanantigravity.com/news/space/eugene-podkletnov-on-antigravity.html#sthash.SIC2Agjw.dpuf"

"American Antigravity" was founded in 2002 between a vision to forwards antigravity and zero-point vigor research. We cover antigravity, vigor, and embryonic science to assess go the look forward to of space a reality. "

"We're link by Dr. Eugene Podkletnov to sermon recent (2004 to 2013) experimental antigravity research in wisdom modification and superconductors. For violently two decades Dr. Podkletnov has been researching the recount in the company of gravitation and high-temperature superconductors, and fine only published the peer-review consequences of new experiments he's conducted to standard the unexpectedness of a force-beam wished-for by a stock-still superconducting means he's seasoned."

"Podkletnov is all-inclusive for his experiments amid YBCO superconductors, which fashioned a gravity-shielding continue that was investigated by NASA and has been the subject of various peer-review papers. He describes continual his experiments in this area, and indicates that he has completed continual get up in creating an antigravity continue that one-sidedly shields the ritual of objects to be found untouchable the rotary disks."

"Dr. Podkletnov as well describes his "force rafter generator" experiment in detail, and provides insights here improvements that he's completed over the last decade to choose the force fashioned by this experimental gravity-beam. The force rafter is generated by smart a high-voltage get away from a Marx-generator regulate a YBCO emitter incomplete in a repetitive outlet, and Podkletnov has described it as being powerful lots to stick over objects in the lab, as well as beneficial of being tuned by alike bump holes in strapping goods."

"Podkletnov only published a peer-review paper on the force rafter experiment entitled "Observe of Simple Kindred between Somberness Impulses and Number of the Degree of Somberness Impulses" through between co-author Dr. Giovanni Modanese, and describes the findings of his study, which complex measuring the unexpectedness of the force-beam through two outcast, but cross-correlated guide techniques. On one occasion aware damaging, Podkletnov has found the unexpectedness of the antigravity impetus to be a propos 64 get older the unexpectedness of light (64c), which he indicates does not confrontation between fresh interpretations of Relativity Philosophy."

"In hoard, Podkletnov describes an antigravity continue generated by rotary repetitive fields that requires no superconductors to be generated, and suggests that it may cause an on sale stratagem for later space & vigor research."
