The Sky is Watching: Excerpt

That Friday night, for the sake of appearances, Quincie hung out with some of her track teammates after practice. By ten o’clock, she had enough of the inane conversations, forced laughter, and awkward pauses. She politely excused herself for the night, thankful to be rid of it all. A call came in from Shara while she was driving home, a call she thought about not answering. She turned down her radio.

“Hey, what’s up girl?” she said, and immediately had to pull her ear away from the phone.

“What’s DeAndre’s number?!” Shara yelled, furious about something.

“DeAndre? I thought you were hanging with Steven tonight.”

“I called his cell, and some other bitch answered,” she griped. “He grabbed the phone from her and tried to say it was his sister!”

“Maybe it was his sister.” Quincie tried to stifle her laughter.

“Yeah right,” Shara shot back. “What sister asks, ‘Who’s that bitch, and does she know about our son?” Quincie burst into laughter.

“It’s not funny! Anyway, what’s DeAndre’s number?!”

“Why DeAndre?  You haven’t spoken to him since before school started; and why the hell do you think I would have his number?”

“Because DeAndre is Steven’s cousin, and I can use him to get revenge, and I texted you his number that time I went out with him, remember? In case something happened to me.”

“Oh, right.” Quincie exhaled, remembering that, as a safety precaution, they agreed to send one another the cell number of the guy they were going out with so if either one of them went missing, the police would know where to start. It was always Quincie who got the texts, however, since she was never the one going on a date.

“You know you’d only be making a fool of yourself, right?” Quincie advised. “If you took the time to think about things instead of just reacting, you’d—”

“Quincie, please! I need the number, not a damn lecture!”

“I’m driving right now,” Quincie remembered the day her father bought her car; particularly the ten-minute speech he gave about not talking on the phone while driving. “I’m almost home.”

“Pleeeeaaaaasssse?!” Shara begged.

“Oh God, hold on a minute!”  Quincie pulled up to a four-way stop sign intersection and decided it was okay to look for the number since there were no cars behind her. After a few moments, she wished she had picked a less-scary place to stop. There was nothing but tall grass and woods in every direction, and it looked as if something would jump out and grab her at any moment. She locked the car’s doors and activated the speaker function on her phone.

“Are you there, Shara?” She asked, checking to make sure that the phone’s audio had switched over.

“I’m here.” Shara’s pitchy voice came back through the speaker.

“Okay, talk to me. I’m stopped in a scary place right now.” Quincie scrolled through her text messages searching for DeAndre’s number.

“I appreciate you,” Shara said.

“You’d better!” Quincie’s voice was trembling a little. The wind had picked up, and she looked around and swore that the dried-out weeds surrounding the intersection were coming to life as they rustled and swayed. She found the number, copied it into a new text message, and sent it to Shara.

“I just sent it to you. Did you get it?”

“What did you say?” Shara asked. “I didn’t hear that.”

“I said, ‘did you get it’?”

“What? Speak into the—” Shara’s voice disappeared in a cloud of static, and then cut out completely.

“Hello?” Quincie looked at her phone and saw that she had no signal. “I’m out of here!”

When she looked down the road, she saw a light building just over the horizon, a light so large and so bright, it looked like the sun rising in the dead of night! It grew in intensity until the source appeared at the top of the hill, washing out the darkness. It slowly made its way toward the intersection where she had stopped.

The intensity of the light caused the transitional lenses in her glasses to darken, which enabled her to make out a large black object at the light's center.

“What kind of car is that?” She asked herself, growing more frightened as she saw that, this ‘car,’ floated just above the ground!  The weeds on the side of the road were being pressed flat by some eerie, unseen force generated by the object as it moved.

It came to a stop just across the intersection, directly in the center of the road, blocking her path; its wraith-like blackness was surrounded by brilliant bluish-white light, making it impossible for Quincie to recognize, even from this short distance. When the lights began to overwhelm the shaded lenses of her glasses, she had seen enough, but when she stomped on the gas pedal, nothing happened! She looked down and saw that her dashboard had gone dark. She turned the ignition key but heard only the clicking sound it made in the lock. The car was completely dead! Terrified, she watched the object hover at the opposite side of the intersection, making no attempt to proceed across. She felt the ominous sensation of being watched.

There was a sudden sinking feeling in the pit of her stomach; like the feeling one gets when riding a roller coaster over a drop. She recoiled from something that floated by her face. She lifted her glasses and looked around the inside of her car. She saw all kinds of objects drifting in the cabin; coins, pens, keys, almost the entire contents of her bag, floating as if suspended in water. She let go of her phone and watched it drift out of her hand.  It was as surreal as it was frightening.  She was relieved when two patrol cars from the Sheriff’s Department came to a screeching halt in the middle of the intersection, directly between her and the strange object. As their car’s lights and sirens flickered and went dark, two deputies jumped out and began shouting at the object from behind their guns. A loud, deep droning noise, like the kind made by a large generator, shook the area, and the outlines of everything that she could see became distorted by the vibrations. That feeling in her stomach got worse, and she could feel her car rising in the air. She looked up and saw the deputies and their cars suspended several feet off the road, by what means, she didn’t know or see. She started screaming; her voice was deafening in her car’s small cabin. She wanted to jump out but was too scared. There was the sharp crack of gunfire as the deputies opened up with their pistols. A series of lights began to strobe all over the strange object, in rapid succession. They mesmerized Quincie, getting brighter and brighter until... https://www.amazon.com/dp/B075Q48MPR

Excerpt- Vacuum Draft Flows Part I

Although the following novella excerpt is in a separate universe from DARK EDGE, I've still been considering publishing within the next few months once the design portion of DARK EDGE has slowed down.

Excerpt- Vacuum Draft Flows Part I

"CHAPT 3

                Green means go and the seconds in between become an infinite and hopeless abyss. The abyss consumed the fears, hopes and dreams of all who found themselves in its presence. Regret, that so many things have been left undone and too many things left unsaid. Pain, that there are no more opportunities and this is the absolute end of all things. Finally, bliss once a man or woman can sweat pure adrenaline and testosterone fuels superhuman strength and senses. Human eyes adjust to slits, brows are frowned, teeth are grit and ground into dust, fingers tremble to crush metal held by throbbing palms, muscles twitch and spasm begging for immediate use. Death is but a weak ghost afraid to take the souls due to him, souls so powerful in this moment that even the reaper couldn’t pull them into the abyss before they willingly conceded to perish.

“Fuck Death” whispered Celia.     "

Meanwhile We Are Here...

Image Source: Meanwhile, In America

Topics: Commentary, Politics, Science

A search term "war on science" will bring up several posts (this one now included) that predate our current epoch. We have a chief executive that used to be a reality show host, insisting on meting out his brand of "diplomacy" at 140-character increments - some misspelled. It like many social platforms was created by science, the very science his administration has decided must kowtow to "alternative facts" and unicorns.

The meme seemed apropos the day after "The Handmaid's Tale" won an Emmy for Best Drama series on Hulu (having read the novel, the reason why I purchased a subscription). Again, a venue we all take for granted on our laptops and Amazon fire sticks, also created by science.

An exhaustive list by Science Blogs follows. My Monday gallows humor, but don't lose heart or get exhausted.

The last one of these was in mid-June, so we’re picking up all the summer stories of scientific mayhem in the Trump era. The last couple of months have seemed especially apocalyptic, with Nazis marching in the streets and nuclear war suddenly not so distant a possibility. But along with those macro-level issues, Trump and his cronies are still hammering away at climate change denial, environmental protection, research funding and public health issues. As exhausting as it seems — and this is part of the plan — amongst all of us opposed to Trump, we need to keep track of a wide range of issues.

If I’m missing anything important, please let me know either in the comments or at my email jdupuis at yorku dot ca. If you want to use a non-work email for me, it’s dupuisj at gmail dot com.

The selections are by no means meant to represent a comprehensive account of everything written about science and science-related over the last few months. I’m not aiming for anything than complete or comprehensive. For example, there are probably hundreds of articles written about climate-change related issues over that period, but I’m just picking up what I hope is a representative sample.

Dénouement...

For Mildred D. Goodwin, September 15, 1925 - May 7, 2009. Happy birthday, mom. As far as this serendipity, I'd like to think she would have enjoyed it.

Friday morning (Sept. 15), Cassini will complete the orbital pirouettes of its seven-year Solstice Mission and complete a self-destructing descent into Saturn's atmosphere. This fierce ending is dramatic for a purpose: It will prevent Earth microbes from contaminating Saturn's nearby moons.

When NASA's Cassini spacecraft completed its first tour of Saturn in 2008, the mission team had to decide what would come next. [Cassini's Saturn Crash 2017: How to Watch Its 'Grand Finale']

Cassini could have parted ways with the ringed planet. In 2009, studies showed that Cassini had enough fuel to reach Uranus or Neptune. Cassini could have traveled in the other direction, toward Jupiter, or it could have been sent to visit an assembly of asteroids known as the Centaurs in the outer limits of the solar system.

Instead, scientists chose to continue making discoveries about Saturn and its moons — first through a two-year extended mission known as the Cassini Equinox Mission, and then with a second extension in 2010 that would bring the spacecraft to the very limit of the fuel it carried. That made it clear that Cassini's third mission, the Solstice Mission, would be how the spacecraft would end its career. It was during these missions that scientists discovered that two of Saturn's moons, Titan and Enceladus, showed signs that they were well suited to life. But why the fiery plummet?

"The spacecraft will burn up and disintegrate like a meteor in the upper atmosphere of Saturn," Preston Dyches, of NASA's Jet Propulsion Laboratory (JPL), told Space.com via email. "This was determined to be the best way to ensure the safe disposal of the spacecraft, so that there would be no chance of future contamination of Enceladus by any hardy microbes that might have stowed away on board all these years."

Jupiter's Northern Lights...

Topics: Astronomy, Astrophysics, Planetary Science, Space Exploration

Evidence from the Juno probe’s close flights past Jupiter indicate that the gas giant’s dazzling polar light shows are caused by a mysterious mechanism different from the one responsible for intense auroras here on Earth.

On Jupiter, as on Earth, the northern and southern lights are produced by charged particles from the Sun colliding with gas atoms in the atmosphere and releasing energy in flashes of light.

Jupiter’s aurora is the brightest in the solar system, so planetary scientists assumed it was produced by the discrete process.

However, a paper in Nature analyzing data from Juno’s low-altitude passes over Jupiter’s poles shows that, while there are extremely intense electric fields aligned with the magnetic field and signs that electrons are being accelerated downwards, the resulting auroras were much dimmer than those produced by the broadband process.

Why? The authors don’t know, though they speculate that Jupiter’s intense auroras may be started by a discrete process creating a stream of electrons that is then disrupted and diffused by the magnetic field fluctuations that produce the broadband process.

NanoVelcro...

For any couple who has witnessed an amniocentesis with WIDE eyes (as I did), this advance should be a welcome relief.

Circulating fetal nucleated cells (CFNCs) in the blood of pregnant women is an ideal source of fetal genomic DNA that can be used for prenatal diagnostics. However, the problem is that there are only a very small number of CFNCs in maternal blood. A team of researchers in the US, China and Taiwan has now developed nanoVelcro microchips that can effectively enrich a subcategory of CFNCs, namely circulating trophoblasts (cTBs) in blood samples. These cTBs can then be isolated using a laser microdissection technique for subsequent genetic testing.

Current prenatal tests for diagnosing foetal genetic abnormalities rely on invasive, “harvesting” procedures, such as amniocentesis and chorionic villus sampling. Although highly valuable, they can increase the risk of miscarriage. Whole foetal cells circulating in an expectant mother’s blood could also provide important information on foetal DNA since they contain entire genomes, but until now it has been very challenging to capture these cells because they are only present in small quantities.

The new nanoVelcro microchips developed by Hsian-Rong Tsung of the California NanoSystems Institute at the University of California at Los Angeles and colleagues can effectively enrich cTBs from blood samples. These cells can then be isolated using a technique called laser capture microdissection (LCM) for subsequent genetic testing.

The researchers (who initially developed their microchips for detecting low concentrations of tumour cells circulating in blood) made their devices by nano-imprinting them on a spin-coated PLGA substrate (see image). To enrich the cTBs, they grafted a biotinylated anti-EpCAM (which is a trophoblast surface marker) onto the imprinted nanoVelcro.

For the genetic characterization, they isolated at least three individual cTBs and pooled these together in a 0.5 mL polymerase chain reaction (PCR) tube for whole genome amplification (WGA). They then subjected the resulting amplified DNA to so-called array comparative genomic hybridization (array CGH) and short tandem repeat (STR) assays.

Jonathan Ng, a Princeton University graduate student at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL), has for the first time applied a fluid simulation to the space plasma process behind solar flares northern lights and space storms. The model could lead to improved forecasts of space weather that can shut down cell phone service and damage power grids, as well as to better understanding of the hot, charged plasma gas that fuels fusion reactions.

The new simulation captures the physics of magnetic reconnection, the breaking apart and snapping together of the magnetic field lines in plasma that occurs throughout the universe. The simulations approximate kinetic effects in a fluid code, which treats plasma as a flowing liquid, to create a more detailed picture of the reconnection process.

Previous simulations used fluid codes to produce simplified descriptions of reconnection that takes place in the vastness of space, where widely separated plasma particles rarely collide. However, this collisionless environment gives rise to kinetic effects on plasma behavior that fluid models cannot normally capture.

Minuscule to Immense...

Artwork by Ana Kova

Topics: Astrophysics, Big Bang, Neutrinos, Particle Physics, Theoretical Physics

In particle physics, scientists study the properties of the smallest bits of matter and how they interact. Another branch of physics—astrophysics—creates and tests theories about what’s happening across our vast universe.

While particle physics and astrophysics appear to focus on opposite ends of a spectrum, scientists in the two fields actually depend on one another. Several current lines of inquiry link the very large to the very small.

The seeds of cosmic structure
For one, particle physicists and astrophysicists both ask questions about the growth of the early universe.

In her office at Stanford University, Eva Silverstein explains her work parsing the mathematical details of the fastest period of that growth, called cosmic inflation.

“To me, the subject is particularly interesting because you can understand the origin of structure in the universe,” says Silverstein, a professor of physics at Stanford and the Kavli Institute for Particle Astrophysics and Cosmology. “This paradigm known as inflation accounts for the origin of structure in the most simple and beautiful way a physicist can imagine.”

Scientists think that after the Big Bang, the universe cooled, and particles began to combine into hydrogen atoms. This process released previously trapped photons—elementary particles of light.

The glow from that light, called the cosmic microwave background, lingers in the sky today. Scientists measure different characteristics of the cosmic microwave background to learn more about what happened in those first moments after the Big Bang.

According to scientists’ models, a pattern that first formed on the subatomic level eventually became the underpinning of the structure of the entire universe. Places that were dense with subatomic particles—or even just virtual fluctuations of subatomic particles—attracted more and more matter. As the universe grew, these areas of density became the locations where galaxies and galaxy clusters formed. The very small grew up to be the very large.

Scientists studying the cosmic microwave background hope to learn about more than just how the universe grew—it could also offer insight into dark matter, dark energy and the mass of the neutrino.

What can particles tell us about the cosmos?The minuscule and the immense can reveal quite a bit about each other.Amanda Solliday, Symmetry Magazine

I have a pre-order that needs some reviews.

Hey BSFS community!

If you're familiar with my work, then you've probably heard of "Squirrels & Puppies" and "Flowers & Kittens".  They're short story collections of the weird, dark, and slightly humorous.  I like dealing with the ideas of race, religion, and morality, and in this new book, "Hugs & Bunnies: Weird and Dark Tales", the nature of God will be one of the themes.  He's going to be symbolized as a giant robot, a sex doll, and a bunch of blue flowers among other things in this book of short stories. 

It's available for pre-order, and it needs some reviews.  I'll happily send you a free copy in exchange for a review.  It comes out on December 1st.  Oh, before I forget:

WARNING: SCENES OF GRAPHIC VIOLENCE.

There ya go.  Thanks again BSFS!

Almost Cliché...

Satellite Image of Hurricane Irma from Space, Space.com

Topics: Climate Change, Economy, Green Tech

I saw "An Inconvenient Sequel" about a month ago. It's almost cliché to use the term "super storm," or in our case of so soon on the heels of Harvey in Texas with Irma in Florida, plural. I blogged about it. I ate popcorn. I conveniently compartmentalized its warnings until now. My apathy is we haven't changed one iota since Katrina or Rita. Cliché storms, starving polar bears, the Antarctic glacial sheet melting...we appear to be ready for football and the next chapter of the Kardashians. I am as concerned for family and friends in Florida as I was in Texas, bracing for the next cliché; before the end of hurricane season and the beginning of the winter ahead. Whether bitter or mild, it will not be "normal."

As with my advocacy of green tech (and anything tech), I can see one clear benefit for fighting climate change: employment. It more than incarceration tends to guarantee stable societies. The coal jobs that used to sacrifice human life and limb as well as a few drilling jobs for the most part are now done by robots. Europe and other countries are not letting "grass grow under their feet" technologically speaking. Chancellor Angela Merkel seems determined for Germany to occupy that well-deserved space as (now) leader of the free world will indeed be a woman...just not an American.

I follow many blogs, Stone Kettle Station being a gem. I almost titled this post with a cliché/expression Jim Wright used in this posting: "Creationists don't build starships." Neither will we, at this point in our technologically lazy history. I say lazy in the sense one does not fabricate a "science" out of whole cloth when the results of observation and experiment reported by the actual subject makes you uneasy. Advocating for it to be taught next to actual science K-12 is galling. It propels us from Democracy to Idiocracy, no suspended animation required.

We're already on a spaceship called Earth without the need to create fantastic engine drives or exotic technologies. It's power source is a fusion reactor at the center of our solar system, it likely forming some distance from here in a star cluster (and a twin sister), along with the precious metals we esteem so highly. Our ship travels space in 365.25 day increments as the system travels the Milky Way as the Milky Way traverses the existing stars, many we have not observed and only discover as we meander the Cosmos. In this sense, we're all astronauts. As such, we're on a ship with a volume, mass and density. It can only give limited supplies of fuel, food and resources. Some of us hoard resources and abuse ship supplies. To compartmentalize those resources, we demarcate ourselves as rich, poor, black, white, makers, takers, winners, losers, deserving, not deserving; human...NOT human. Eventually vessels give way to the wear-tear of Entropy. As one of the lessons of the Titanic attests, even the strongest of bows will break on blunt and obvious icebergs. Captain Ahab is cultural metaphor, known without reading Melville's long novel, a byword and proverb of obsession leading to destruction by relentless natural forces, the leviathan a phallic symbol.

To quote President Bush verbatim: "we're addicted to oil." Our world economy became global on the gold of cotton picked by slaves. Now we're beholden to the value of the dollar and OPEC futures. We would have to halt production full-stop and leave current fossil fuels in the ground, according to The Guardian: our gasoline, Vaseline, plastics, mobile phones, automotive and apparel industries aren't about to let that happen. Controlling the media to the point that an Australian billionaire and a Saudi Prince dictate the thoughts of ditto heads on a media conglomerate 21 years old such that denialism has an obvious profit motive. "Good to the last drop" was a Maxwell House tag line, and may well be our epitaph.

The passengers of the Arbella who left England in 1630 with their new charter had a great vision. They were to be an example for the rest of the world in rightful living. Future governor JOHN WINTHROP stated their purpose quite clearly: "We shall be as a city upon a hill, the eyes of all people are upon us." Source: US History

That famous line has been quoted and paraphrased by President Reagan and recently former FBI Director James Comey. Rather than that puritan and idealistic view of our percentage of humanity and rose-colored view of history, we currently behave metaphorically like the survivors of a shipwreck... on a dung heap.

Project 2061...

TEACHERS INVOLVED IN THE TESTING OF THE NEW CURRICULUM SAID THAT ITS USE OF MODELS PROVIDED STUDENTS WITH TANGIBLE EXAMPLES OF MICROSCOPIC SCIENTIFIC PROCESSES. | JO ELLEN ROSEMAN/AAAS

Topics: Diversity, Education, STEM, Women in Science

I don't plan on being here, seeing I'd be 99. I wish them the best of luck.

As summer draws to a close, participating middle school students will begin tackling chemistry concepts to prepare them for the rigor of high school biology courses.

Students will engage with scientific ideas and practices through hands-on activities and learn to write clear and concise explanations of real-world phenomena as part of a novel curriculum that the National Science Teachers Association Press is slated to publish in mid-September. The collection of 19 lesson plans, titled Toward High School Biology, will be available for purchase and use by teachers in the United States and abroad.

The emphasis the unit places on writing is particularly appealing to Leah Donovan, a science teacher at Oakland Mills Middle School in Columbia, Md., who participated in early tests of the curriculum and has been using the lesson plans in her classroom ever since.

Donovan said her students’ writing skills have improved as a result of the curriculum’s emphasis on teaching them to explain scientific concepts. Her favorite example of how such skills are built relates to the chemical makeup of the Statue of Liberty.

Students study images of the Statue of Liberty, paying particular attention to the 31 tons of copper sheeting that covers its surface and taking note that it is green instead of brown. They are told that, after years of exposure to the air’s oxygen and carbon dioxide, a layer of green copper carbonate has formed on the statue. Students then explain how the chemical reaction responsible for the statue’s green hue takes place.

Quantum Light on a Chip...

A laser (green) excites the quantum dot (red) in this diagram of the chip. The ring, which is tuned via applying voltage to the yellow contacts, manipulates the characteristics of individual photons (ellipsoids).
Topics: Laser, Nanotechnology, Photonics, Quantum Dots, Quantum Mechanics, Solid State Physics

Ideally, optical circuits would generate and shuttle light so well that researchers could use them to transmit encoded information, sense chemical species, and perform quantum computations. But because the components for each circuit—light sources, mirrors, splitters, filters, and waveguides—occupy several feet of table space, they cannot manipulate light down to the nanoscale. In an effort to downsize components and produce practical quantum photonic devices, researchers have been tinkering with nonlinear materials, atomic defects, and traditional semiconductors at the nanoscale.

Now Ali Elshaari at KTH Stockholm and his colleagues have taken a major stride by embedding circuit components on a CMOS-compatible chip that takes up a millionth the area of a tabletop apparatus. The key innovation was implementing precise control over quantum dot light sources, which emit photons in specific quantum states, including entangled ones, when excited by lasers. Scientists had struggled to control the dots’ emission and integrate the dots with waveguides for on-chip applications. Elshaari’s team devised a special geometry that optimized the alignment of the dots’ light emission with the fundamental waveguide mode, which resulted in high coupling efficiencies. To control the emission, an electrically tunable device acted as a spectral filter that could fine-tune the photon characteristics.

Nanoscale Quantum Memory...

Topics: Modern Physics, Nanotechnology, Quantum Computer, Quantum Mechanics

A new type of optical quantum memory that could be integrated with other components on a chip has been unveiled by physicists in the US. The device overcomes an important challenge facing researchers trying to make quantum computers based on light – how to efficiently capture a photon within a sub-micron-sized structure.

From sending messages that could never be bugged to linking together quantum computers in a "quantum Internet", the ability to exchange quantum information may be vital to the future of technology. This will not be possible, however, without quantum memories to store quantum states and release them when needed.

In the Internet of today, information is sent between computers through a distributed series of nodes called routers. "Packets [of information] are maybe stored for some time and then they are sent," says Andrei Faraon of the California Institute of Technology, "There is some control over the timing of the packet." An optical network that uses photons to carry quantum information would require analogous nodes to store not strings of ones and zeroes (bits) but the full quantum states of individual photons (quantum bits or qubits).

There are currently several different quantum memories under development – some storing qubits as collective excitations in ensembles of atoms, others using solid-state crystals. Among the second group, crystals doped with ions of rare-earth metals have proved successful because rare-earth ions have sharp, stable electronic transitions that can couple to photons and preserve their quantum states. However, absorbing a photon generally requires millimetre- to centimetre-thicknesses of material, making quantum memories rather large.

TERROR ON TELDERAN
SYNOPSIS: In 1990,
After breaking away from the Planetary Alliance the planet Otar finds it’s self on the brink of ruin. In a desperate move, their leader Rotart makes a foolish attempt to terra form the planet Telderan so that he may claim it and relocate the Otarian race. Ancient oracles have been warning Alliance leaders for years that such an attempt would be made and that it would have catastrophic results for planet Earth billions of miles away. Rayna, High Ruler of the Southern Quadrant of Lazon and J’lore Chief Council of Earth’s Guardians have been lifelong friends. Although Earth Guardians are considered outlaws by the government Rayna sympathizes with their cause to save the human race. Earth’s Guardians is also aware of the impending disaster for earth but Rayna confirms it. Taz, son of the ruthless dictator of Otar is dispatched to clear Telderan of the handful of inhabitants so that the terra forming process can begin. His harsh and heavy handed ways do not go down well with the settlers and his father's confrontation with leaders of the Planetary Alliance does not fair any better. Only time will tell if the Planetary Alliance’s oracles were right.
